Fresh water is applied to the interior wall of the evaporator shell.

Using a refrigeration process, heat is removed from the fresh water in order to freeze it.

As the water freezes onto the wall of the evaporator shell, the auger scrapes it off and into a discharge port. The ice shavings are then compressed and pushed into the ice transport tube which runs to the ice-collection bin. See Figure 1.

EFRIGERATION

ROCESS

The basic principle of an ice machine system is that a liquid refrigerant absorbs heat as it turns into a gaseous state

(evaporates) and releases heat as it turns back into a liquid state (condenses). The system consists of five main components:

•

Evaporator

- Absorbs heat from the fresh water in the evaporator shell causing the fresh water to freeze.

•

Auger

- Scrapes the frozen fresh water from the interior sides of the evaporator shell and extrudes it into the discharge hose.

•

Condenser

- Releases heat into the system’s circulating seawater and turns the refrigerant gas back into a liquid.

•

Compressor

- Drives the refrigerant through the loop.

•

Metering Device

- Meters the flow of refrigerant to the evaporator.

The ice maker’s refrigerant compound has a very low boiling point. It flows in a closed loop between an evaporator and a condenser, alternately absorbing and releasing heat. This process removes the heat from the fresh water in the evaporator/ auger assembly and causes the fresh water to freeze on the inside of the evaporator wall. The heat absorbed by the refrigerant is transferred to the seawater.

A water pump circulates seawater through the inner tube in the condenser coil which cools the refrigerant in the outer tube and condenses it from a gas into a liquid. The heat from the refrigerant is exchanged to the seawater and discharged overboard.

The liquid refrigerant is then pumped through the evaporator coil and the cycle repeats. See Figure 2.

EMPERATURES

Seawater and freshwater temperatures affect the ice machine’s efficiency and capacity. The system is most efficient when the seawater and fresh water temperatures are 55-80°F (13-27°C). The ideal temperature for both is 70°F (21.1°C). See Figure 3.

High Temperatures

- As water temperatures approach 90°F (32°C) and above, the water’s ability to absorb heat diminishes, so the capacity of the system decreases. Also, when seawater temperature increases above 90°F (32°C), the system could sustain a high-pressure shutdown to protect the compressor.

Low Temperatures

- As water temperatures approach 45°F (7.2°C) and below, the water’s ability to provide heat exchange diminishes, so the capacity of the system decreases. Also, as the water temperature decreases, the system could sustain a lowpressure shutdown to protect the compressor.

CAUTION

Extreme care should be taken in operating any unit below seawater temperatures of 45°F (7.2°C). The seawater could freeze in the condenser tubing, possibly causing it to burst, which is not covered by the warranty.

T

EMPERATURE

The Effect of Ambient Air Temperature

The ambient air temperature affects the ice machine’s efficiency and capacity, but not as significantly as the water temperatures. The system is most efficient when the ambient air temperature is 55-80°F (13-27°C). At temperatures above and below this range, ice production will decrease. See Figure 3.

The ice-making unit has an R-404A compressor, seawater-cooled condenser, a filter/drier, and an accumulator. The auger assembly contains the evaporator barrel, auger rotor, gearbox, motor, water reservoir, and expansion device.

The freshwater delivered to it is converted to ice which exits the system via an ice-delivery hose routed properly to a storage box up to 35 feet (10.6m) away. See Figure 4 on page 7.

The unit is pre-charged with refrigerant from the factory. The unit has plug-and-play electrical connections for the ice-level sensor and the optional remote display.

The ice-making unit has an electrical control box with digital display that can be mounted on the unit or remotely mounted up to

7’ (2.1m) away.

The control box (Figure 11, page 14) contains the system function switches, digital display, and system indicator lights. It lets you control all system operations and provides visual indications of system activity, such as whether the system is running or has a fault. If a fault condition is detected, the system shuts down automatically. The control panel lets you restart the system after a sustained fault. See the “The Digital Control” on page 14 for further operating instructions.

The ice-storage box is the destination point where the ice will accummulate via the ice-delivery hose. An ice-level sensor installed in the storage box halts ice production when the box is full.

The ice-storage box should be able to hold water and have at least 2" (51mm) of insulation to keep the ice frozen as long as possible. It is helpful to install a drain in the box at the end opposite from the ice input. To improve ice-production performance, keep the drain plugged to prevent cold air and cold water from escaping the storage box.

Seawater is pumped into the ice-making unit to efficiently cool the hot refrigerant via a cupronickel coaxial tube design. The condensing unit may be connected to its own single-station pump or to a larger, multi-station pump via a pump relay box.

The seawater system (Figure 7, page 10) consists of a thru-hull fitting, seacock, strainer, seawater pump, seawater hose, and overboard discharge. There must be water flow of at least 2 GPM / 7.6 LPM (maximum 2.75 GPM / 10.4 LPM) or coil erosion can occur.

Know the frequency and voltage provided where your ice-making system will be used and select the appropriate 60 Hz or 50 Hz model.

Do not operate a 60Hz unit on 50Hz power or a 50Hz unit on 60Hz power, as this will cause damage and void the warranty.

The voltage rating of a unit is a nominal rating. The voltage in a given location may be higher or lower by as much as 10% and the system will still operate correctly. For example, in a 60 Hz environment you may see 110 VAC to 120 VAC, or 208 VAC to

240 VAC. In a 50 Hz environment common voltages range from 220 VAC to 240 VAC.

Never install the unit in the bow of the boat.

Dometic ice-making units are designed to be installed in any convenient location on the transom, in the aft, or in a machinery space that does not require ignition protection that is as far aft of midship as possible. The unit can be located in living areas if necessary. Some considerations:

• This equipment is not ignition protected per CFR 183.410 and may not be installed in areas that may be exposed to flammable gas.

• The unit will produce condensation, so the drip pan is necessary.

• The unit is water cooled and does not need direct ventallation, but do not install in a sealed space.

• The space around the unit may be insulated to reduce noise if necessary.

Site Location Check List

• Location is aft of midship.

Never install the unit in the bow of the boat.

• Location is not exposed to flammable gas.

• Location provides adequate space for access to refrigerant, seawater, and electrical connections.

• Location provides accessibility for service and maintenance.

• Location is away from direct spray, from engine air intakes, and from water washdown.

• Mounting space is a flat, horizontal surface.

1.

Do not remove any covers, caps, or fittings that may expose any wiring or refrigerant until you are ready for those steps of the installation.

2.

On a flat, horizontal surface, orient the unit so the refrigerant, seawater, and electrical connections are accessible and use the 4 provided hold-down clips to secure it.

3.

If you decide to remotely mount the control box, be sure it is away from direct spray, from engine air intakes, and from water washdown.

4.

If pump wires need to be extended by butt connections, make sure they are tightly crimped and heat shrunk.

The condensate drain pan is 2.0” (51mm) high with one drain location. During conditions of high humidity, condensate may be produced at a rate of approximately one-half gallon (1.9 liter) per hour. With this in mind, it is important to route condensate drains downward to a sump pump. It is not recommended to route condensate drains to the bilge.

After the condensate drain installation is complete, test the installation by pouring one quart (liter) of water into the pan and checking for good flow.

Planning the Route

The maximum length of the ice-delivery hose is 35 feet (10.6 m) under ideal conditions.

The best hose routing provides a level but slightly upward rise from the ice maker to the ice-storage box, with very few bends.

No bend should be tighter than a radius of 18" (458mm). Refer to Figure 4 below to see:

•

Best Routing

- A continuous uphill route of travel from the ice maker.

•

Good Routing

- A continuous route of travel from the ice maker, with only one high spot.

•

Acceptable Routing

- A route of travel from the ice maker which includes one low spot and two high spots.

Figure 4: Routing of Ice-Delivery Hose

Mount the ice-delivery hose as high as possible in the ice-storage box.

Figure 5: Heat & Stretch

Auger End of Hose

Procedure

1.

The hose delivery location should be as high as possible

in the icestorage box and facilitate the best hose route from the auger (as described above and shown in Figure 4).

2.

Install the proper thru-hull in the ice-storage box using the supplied fitting. The thru-hull must be large enough for the 3/4" (19.1mm) ice-delivery hose.

NOTE:

In cases where the EI540D is replacing an existing older Eskimo Ice system that used a larger fitting and hose, it might be possible to insert the newer, smaller hose inside the existing hose and use the existing icedischarge thru-hull.

3.

Insulate the full length of hose with 1-1/8" (29mm) ID, 3/4" (19mm) thick wall insul-tube, minimum.

4.

Double clamp thru-hull end so the hose will not get pulled out. In addition, PVC glue may also be used at the thru-hull end.

5.

The hose at the auger end must be stretched in order to fit over the auger spout: Heat 1.75” (45mm) of the hose end in hot water (160°F / 71°C) or with a heat gun to soften, then stretch it by inserting and rotating pliers inside the tube. See

Figure 5, page 7.

L-3040 ENGLISH 7



6.

The EI540D now REQUIRES a Constant Torque Hose Clamp to secure the ice delivery hose to the auger spout.

It is supplied with the machine and attached to the Auger spout with a black wire tie. The clamp must be installed behind the 8 protruding dimples on the auger ice spout. The use of another type of clamp will void the warranty and liability of ice overflow and damage if the hose comes off while producing ice. Secure hose end with constant torque hose clamp to auger spout.

It is CRITICAL that you check the integrity of this hose connection when you perform the system start-up test.

(See “Mandatory System Start-Up Test” on page 13.)

7.

Securely strap hose to bulkhead every 12” (30.5cm), keeping in mind that the hose will be much heavier once filled with ice. Be careful not to kink, flatten, oval or crush hose, because any obstructions will prevent free flow of ice.

ENSOR

To prevent overflow, this sensor stops ice production when the ice in the storage box reaches the level of the sensor. Use

Figure 6 below to determine placement for the ice-level sensor at the storage box location. The EI540D will not operate without the ice-level photo sensor installed.

Test the photo sensor for correct operation to avoid machine damage and avoid ice overflow. See “Mandatory System Start-Up

Test” on page 13.

1.

The sensor must be located 2.5” (64mm) minimum to 3” (76mm) maximum to the left or right side of the ice-delivery hole. Drill a 23/32" (19mm) hole for sensor.

2.

Use the 2 lock nuts provided to secure sensor into the hole.

3.

Use marine-grade sealant around the hole if desired. (Remember that the unit may have to be removed at some time.)

4.

Route the cable to the ice maker’s electrical box and plug the end into the ice-bin sensor socket. See the appropriate electrical wiring diagram in this manual for the voltage model you are using.

NOTE wiring changes from earlier Eskimo Ice models:

The wiring has changed in the electrical box for the ice sensor. There are 4 wires in the sensor harness: white, black, blue and brown. The signal wire in the center position of the ice-level sensor plug is now a white wire, not black as before. The white wire was previously cut off at the grey insulation. Now the black is cut off and the white is used. Note the photo sensor can be used for old as well as new. It is just dependent how it is wired.

Feedwater for the unit should be fresh water supplied by the boat’s potable water system. The water reservoir has a float switch to ensure the unit does not operate without a water supply.

L-3040 ENGLISH



Requirements

• Supplied feedwater must have a pressure of at least 15 PSI.

• The water system must be able to supply at least 4 GPH when the ice maker is operating.

• Install the in-line filter (supplied in kit) just prior to the unit to remove sediment which may clog the needle valve in the water reservoir.

• Dometic recommends installing a shut-off valve in the feedwater line between the source and the filter to facilitate filter changes.

WARNING

Use of saltwater as feedwater will damage auger components and evaporator barrel and will void the warranty.

WARNING

Failure to install and use the water filter included with the installation kit will void the warranty.

Note, if unit is purchased separately you must also purchase the water filter to maintain warranty.

Procedure

1.

Run copper tubing or equivalent from the freshwater source to the in-line water filter.

2.

Run copper tubing or equivalent from the water filter to the water input, and connect with the supplied 1/4" SAE male flare connection on the unit.

3.

Ensure there are no leaks in the field-installed portion of the system.

Water Quality and Filters

No water from a municipality is “pure” feedwater, but water from a vessel’s onboard water maker comes close. The feedwater problem is that water contains suspended and dissolved feedwater solids. Pure water freezes first, leaving the feedwater solids to increase in concentration in the unfrozen feedwater. Solids also bond to the evaporator wall during feedwater freezing, forming scale. Eventually, built-up scale will shorten machine life.

A Dometic-supplied filter for use with ice makers must always be used, otherwise the warranty will be void. Replace the filter at least twice yearly, or more often if the machine is used frequently. While filters help clean the water, a 6-month cleaning of the evaporator barrel is required. See “Evaporator Cleaning” on page 21 of the “OWNER MAINTENANCE” section.

Using

saltwater

to make ice is

not

approved by Dometic. Saltwater is very corrosive, and it contains many more dissolved and suspended solids than freshwater. If you want a brine solution for your catch, we suggest sprinkling salt over the ice in the storage box. USE OF SALTWATER AS FEEDWATER IN ANY DOMETIC ICE MAKER WILL CAUSE SEVERE DAMAGE AND

VOID THE WARRANTY!

Self-Draining System

A poorly plumbed seawater system is the most common installation problem. When water flow is lost, not only will the ice maker cease to produce ice, but the pump could be damaged from running without water flow.

When using a centrifugal seawater pump, it is imperative that the seawater piping be routed continually uphill from the thru-hull to the condenser, then smoothly up or down to the overboard discharge without any dips or loops, and with only one high point in the system. This type of routing is called self-draining because all water will drain out of the piping if the boat is taken out of the water.

If air gets into the system, which can happen in heavy seas or with a sharp turn, it can become trapped in the pump. Because centrifugal pumps cannot pump air, water flow is lost. A self-draining system, however, allows air in the piping to rise naturally through the pump and be expelled. It also makes winterizing the system much easier. Figure 7, page 10 shows a properly plumbed system and some common mistakes.

L-3040 ENGLISH 9


Figure 7: Seawater Piping Recommendations


10

Thru-Hull Inlet Fitting

A separate thru-hull fitting must be installed for each seawater pump. Do not attempt to draw water from the thru-hull fitting of an engine, generator, or other device.

Install a scoop-type thru-hull fitting:

1.

Drill a properly sized hole for the thru-hull fitting as far below the water line and as close to the keel as possible.

2.

Make sure the scoop of the thru-hull fitting faces the bow.

3.

Bed the scoop with marine sealant designed for underwater use, and tighten the nut onto the thru-hull to secure it.

Seacock

The seacock must be accessible and easy to close in case of emergency or to clean the strainer.

1.

Install a full-flow seacock directly onto the thru-hull fitting.

2.

Use threaded-seal tape to seal the threads.

Seawater Piping

• Only use reinforced marine-grade hose or other suitable piping (PVC, CPVC, cupronickel, or stainless steel).

• Double clamp all hose connections.

• Use only plastic, bronze, or stainless steel fittings (do not use brass).

• Avoid loops or dips in all hose runs.

• Make sure enough hose is used to allow for future removal of components.

L-3040 ENGLISH



• Use the correct size hose, fittings, and components: 5/8” seawater hose, 3/4” inlet. Note that the pump inlet piping

(including thru-hull and strainer) may need to be larger than the outlet pipe size. Do not use pump connections to determine hose size.

• The "pump inlet" recommended pipe size includes all fittings and hose up to the pump connection (thru-hull, seacock, strainer, hose, manifold). The "pump discharge" recommended pipe size includes all fittings and hose from the pump discharge up to the overboard discharge, and should be a minimum of 5/8”.

Strainer

A seawater strainer must be installed between the seacock and the pump, and should be situated to provide easy access for cleaning. The strainer must be located vertically above the seacock and below the pump so any air that gets into the strainer can get out.

1.

Mount the strainer to a bulkhead so it is properly supported before connecting hoses.

2.

Make sure the water flow through the strainer is in the correct direction. Some strainers have an arrow that shows correct flow direction.

3.

Run appropriate seawater piping from the seacock to the strainer, and use threaded-seal tape on pipe threads.

Seawater Pump

Required Flow Rate

The Dometic EI540D ice maker requires at least 2 GPM / 7.6 LPM (or 120 GPH / 454.2 LPH) up to a maximum of 3.5 GPM /

13.2 LPM (or 210 GPH / 792 LPH) of seawater flow for rated performance.

Centrifugal Pumps

Centrifugal pumps are not self-priming, and must be mounted so they are below the heeled waterline in any given operating condition. The pump should be accessible for future service.

1.

Mount the pump so the outlet is directed upward. If you are using the Dometic pump, other mounting orientations are acceptable as shown in Figure 8, and the head on these pumps can be rotated to allow mounting on a vertical bulkhead.

2.

Run appropriate seawater piping from the strainer to the pump, and use threaded-seal tape on pipe threads.

Self-Priming Pumps

Self-priming pumps are available if a centrifugal pump cannot be mounted below the waterline.

Figure 8: Dometic Pump Head Orientation

Correct Orientations

Incorrect Orientations

Manifolds

If a pump serves multiple units, a seawater manifold is needed to supply water to all units. This can be as simple as a tee for two units, or a custom manifold for seven to eight units.

It is very important to consider manifold orientation so that all units get their required flow. See Figure 9 on page 12 for proper orientation tips. Verify the manifold still provides the required flow rate for the ice maker.

A manifold can also be used on the outlets of multiple ice makers when using a single overboard discharge.

L-3040 ENGLISH 11



Figure 9: Seawater Manifold Orientation

Pump Relay

The pump relay (if needed) is generally located in the engine room or mechanical space near the seawater pump, but can be mounted anywhere that is convenient and accessible. It must be in a dry location, away from water spray, with some room for heat dissipation.

Choose your pump relay based on the number of units that will operate off one pump. Choose each trigger to reflect the voltage of the unit it serves. The polarity of the signal from the unit does not matter to the trigger, but the voltage is very important.

Connection to Ice Maker

Connect a hose from water discharge of pump to water inlet on the condensing coil.

Overboard Discharge

Connect a hose from the water outlet of the condensing coil to the overboard discharge. The overboard discharge should be located 1” to 2”

(25-50mm) above the waterline. This facilitates visual confirmation of water flow and also keeps it close to the waterline to minimize splashing.

If the overboard discharge is located below the waterline a valve must be installed per ABYC guidelines.

Note: In some applications a Sea Chest might impede water flow depending on the water volume other devices discharge into the common overboard. Proper water flow must be confirmed to ensure proper operation of ice maker if a Sea Chest is used.

Bonding

Bond all metallic parts (thru-hull, valves, strainer, manifolds, etc.) that are in contact with seawater to the vessel’s bonding system in accordance with ABYC standards. Items should only be bonded or grounded once. If an item is in contact with an electrically grounded part (pump, seawater condenser) then it should not be bonded again.

that you test the durability of the hose connections, the icelevel sensor, and the amp-sensing feature during the installation process:

1.

Run the machine to start producing ice. See “OPERATION” on page 14.

2.

Block the output end of the ice delivery hose and run the system until the machine shuts down with the OCA code to confirm the overload feature.

Note: Image shown is not to scale.

3.

Check to see that the unit displays the

OCA code

indicating an ice-hose clog, restriction, actual auger motor overload, possible motor problem, or internal gear problem. The amp-sensing feature of the control monitors the amp draw of the auger unit and shuts down and locks out when an overload is sensed. The

115V auger locks out at 2.6 amps; the 230V/60Hz and 220V/50Hz augers lock out at 1.3 amps.

NOTE:

The Spout fault code of earlier models is no longer used since there is no spout switch on this unit.

NOTE:

If an OCA has occurred and you remove the immediate obstruction, such as ice piled up in front of the discharge, and then reset the unit, a second OCA might occur if a sufficient amount of time has not elapsed to allow ice to melt in the auger or where ice might be compacted in the hose on a long run.

4.

Check the hose connection at the auger end. It is CRITICAL to make sure that the ice delivery hose did not come off the auger spout or move in any way. If there is a problem, refer to “Installing Ice-Delivery Hose” on page 7 and make the hose secure then retest.

5.

Reset the system and resume ice production to test the photo sensor for correct operation to avoid machine damage and avoid ice overflow. When ice blocks the sensor the unit should stop producing ice, and this should occur before the collection bin overflows.

ONTROL

The control system is programmed to operate the unit within assigned parameters. It uses sensors, timers, and counters to protect system components from failure due to loss of fresh water, loss of seawater, ice clogs, low refrigerant charge, high pressure, low pressure, or auger-motor start failures.

To prevent overflow, a sensor also controls system operation based on ice level in the ice-storage box. The control panel shows system function and failure mode, if one occurs. See “Faults - Events That Interrupt Ice Production” on page 15 for details.

The digital control display panel is also the user interface for programming system parameters. See “PROGRAMMABLE

Your Dometic ice-making system contains R-404A refrigerant, an environmentally safe gas. The unit comes pre-charged with the right amount of refrigerant for operation and should not need seasonal recharging. If recharging is necessary, R-404A should be charged in the liquid phase with “Charge-Guard” and weighed in according to data label located on electric box.

4.

Turn on vacuum pump. Open both high and low manifolds and allow the pump to run so the vacuum reaches 28" HG.

Close gauge-set valves and turn off pump.

5.

Leave the system for 15 minutes then observe the gauges. If any vacuum has been lost, check for leaks, especially at any mechanical fittings.

6.

Repeat the vacuum process until a vacuum of 200 microns or less is achieved, 50 microns is ideal. If the system was open to the environment, allow 12 to 24 hours for evacuation. Close gauge-set valves and turn off pump. If no vacuum is lost, proceed with charging.

NOTE:

If moisture was a problem, refer to Refrigeration Bulletin 02-1 for instructions on clean up. This bulletin is available on the DometicEnviro.com Customer News and Information website under Technical Field Notices 2002: "Control of Moisture in

Close the seacock and remove the inlet hose from the condensing unit. Allow all water to drain from the system. Loosen screws on the pump head to allow water to drain from the pump. Cutoff feedwater supply, and drain the unit. Remove water from the water reservoir inside the unit. You may also add non-toxic antifreeze to the water reservoir.

Use a shop wet-vac to remove the water from the evaporator through the ice discharge spout tube, or remove the water tank assembly from the spout and drain it.

TROUBLESHOOTING GUIDE

Before calling for service, review this list. It may save time and expense. This list contains common occurrences that are not a result of defective workmanship or materials.

If you still need service after trying these procedures, call your local dealer or refer to the back cover of this manual for technical support options..

PROBLEM POSSIBLE REASONS & SOLUTIONS

Unit does not operate at all.

1. Power switch in the “Off” position. Press power switch to turn the unit on.

2. Check for tripped breaker or blown fuses.

3. Significantly low voltage to unit.

4. Misconnected or loose plugs or wiring.

High-pressure fault.

(HPF)

1. Check seawater system for clogs, air trap, faulty pump, dirty strainer, or condenser in need of descaling.

2. Faulty pump relay trigger at relay station (if pump is used for more than one unit). Replace trigger.

Low-pressure fault.

(LPF)

Ice-clog.

(OCA)

1. Low refrigerant charge. Have a certified technician check the pressure.

2. Improperly set Thermal Expansion Valve (TXV). If under warranty, call for authorization before adjusting TXV, otherwise warranty will be voided.

1. Check for obstruction at the ice discharge in the ice-storage box.

2. Check for frozen ice-delivery hose.

3. Check routing for dips or kinks in the ice-delivery hose.

4. Check for auger motor failure.

Feedwater fault.

(H2O)

PROBLEM

Ice delivery volume seems less or slower.

Water leaks.

Display consistently shows

“Full”.

Squeaking or groaning noise coming from evaporator/auger assembly.

Typically heard once per revolution as auger rotates.

Excessive buzzing, grinding noise from evaporator/auger assembly. Usually constant.

Oil in auger assembly drain pan.

POSSIBLE REASONS & SOLUTIONS

1. Check water pressure in boat’s potable water system.

2. Check for a supply valve that has been turned off.

3. Check for a clogged feedwater filter.

4. Check for a cloged Y strainer located on the feedwater line of the unit.

5. Check for a clogged needle valve in the water reservoir.

1. High seawater temperature.

2. High feedwater temperature.

3. Low seawater flow. Check pump and strainer.

4. Drive motor weak. Replace motor.

5. Auger corroded or stained due to water conditions. Clean and/or replace assembly.

6. Inlet water filter or Y-strainer partially clogged. Clean or replace filter. Remove clog.

7. Loss of refrigerant charge. Consult trained technician.

1. Defective water seal. Replace seals.

2. Water level in reservoir too high. Adjust float.

1. Make sure ice sensor is installed in the ice-storage box.

2. Check ice sensor for proper operation.

1. This type of noise is normal during ice production. It is caused by the shearing of extremely hard ice from the evaporator wall. No adjustment is necessary as this is normal.

2. See description of “excessive noise” below to compare.

1. Mineral or scale deposit on auger and evaporator walls. Clean evaporator as described in

“Evaporator Cleaning” on page 21.

2. Low water supply. Check for fouled filter or float valve.

3. Gear-reducer assembly loose on mounts. Tighten the mounts.

4. Gear-motor end-play or worn bearing. Replace worn part.

1. Leaking water seals in the evaporator/auger assembly. Replace seals.
