WARNING You will need:
Explosion Hazard
Keep flammable materials and vapors, such as petrol, away from dryer.
Do not install in a garage.
Failure to do so can result in death, explosion, or fire.
Selecting the proper location for the washer/ dryer improves performance and minimizes noise and possible washer “walk.”
The washer/dryer can be installed in a basement, laundry room, or recessed area.
(See page 2-21) “Drain System.” n A water heater set to deliver 120°F (49°C) water to the washer. n A grounded electrical outlet located within
6 ft. (1.8 m) of where the power cord is attached to the back of the washer. See
“Electrical Requirements.” n Hot and cold water faucets located within
4 ft. (1.2 m) of the hot and cold water fill valves, and water pressure of 20–100 psi
(137.9–689.6 kPa). n A level floor with a maximum slope of 1” (25 mm) under entire washer/dryer. Installing the washer/dryer on soft floor surfaces, such as carpets or surfaces with foam backing, is not recommended. n A sturdy and solid floor to support the washer/dryer with a total weight (water and load) of 450 lbs (204 kg). n A floor drain under the bulkhead.
Prefabricated bulkheads with electrical outlets, water inlet lines, and drain facilities should be used only where local codes permit.
Companion appliance location requirements should also be considered. iMPOrTanT: Do not install or store the washer/dryer where it will be exposed to the weather. Do not store or operate the washer/ dryer in temperatures at or below 32°F (0°C).

GaS PiPe CHarT (naTural GaS)
The chart shows the maximum capacity in terms of cubic feet of gas per hour, for various sizes of pipe at lengths of from 10 feet to 200 feet. The column on the left is the nominal iron pipe size shown in inches. Sizes range from 1/4” to 4”. The next column shows the internal diameter of the pipe in decimal inches.
The numbers across the top of the chart are lengths of pipe from 10 feet up to 200 feet.
The numbers in the body of the chart are maximum capacities of cubic feet of gas per hour.
To determine the cubic feet of gas required per hour, divide the total BTU input of all the dryers which will be on the line by the average
BTU heating value per cubic foot of the gas used.
EXAMPLE:
The dryer has a rating of 30,000 BTU. If the average BTU rating of natural gas is 1000, divide 30,000 by 1000 and get 30. If for example, eight dryers are to be operated on a gas line, the following figures would be used:
30 Cubic feet per hour each x 8 Dryers
240 Total cubic feet of gas per hour
Let’s assume 40 feet of pipe is required. This is how to use the chart:
1.
Look across the top of the chart and find 40 feet of pipe.
2.
Look down into the body of the chart to get to, or just over the maximum needed cubic feet of gas per hour. In this case it will be
245.

Warm Start (after power failure)
A few seconds after power is restored, if a cycle was in progress at the time of the power failure, “RESELECT CYCLE” will flash in the display, indicating the need for a key press to restart washer or dryer.
Washer Door lock
Prior to beginning a cycle, there is a door lock routine of lock/unlock/relock, then cycle begins. The door will remain locked until the end of a cycle or approximately 2 minutes after a power interruption.
Pricing
After the door is opened and then closed following the completion of a cycle, the display indicates the cycle price (unless set for free operation, where the display will flash
“SELECT CYCLE”). As coins are dropped or debit inputs arrive, the display will change to lead the user through the initiation of a cycle.
There are four (4) types of dryer pricing:
Fixed “vend” Pricing
A dryer set up for “Fixed Cycle” operation can only accept additional time accumulated by increments equal to the length of a complete dry cycle. A maximum of 99 minutes may be purchased; no additional credit is given for coins dropped with 99 minutes in the display. accumulator Pricing
If the price is set to one coin 1, then accumulator pricing is in effect. Cycle time can be purchased one coin at a time up to the maximum time of 99 minutes.
Fixed Cycle With Top Off Pricing
A dryer set to offer “Top Off” capability will allow time to be added to an existing dry cycle in increments equal to the number of minutes of dry time per quarter (coin 1), up to
99 minutes, regardless of the cost required to start the dryer. No credit is given for coins or debit inputs entered when the control is displaying 99 minutes.
PR Models: In Enhanced Debit Mode, the top off price can be set independently (see VALUE
OF COIN 2), and the top off time is calculated according to the following equation:
Penny increment offset is not applied to top off purchases.
Free Cycles
This is established by setting the cycle price to zero. When this happens, “SELECT CYCLE” will appear rather than a cycle price. Any cycle started as a free cycle will automatically terminate when the door is opened.
Debit Card ready
This washer/dryer is debit card ready. It will accept a variety of debit card systems, but does NOT come with a debit card reader.
Refer to the debit card reader manufacturer for proper washer/dryer set-up. In models converted to a Generation 1 debit card system, debit pulses represent the equivalent of one coin (coin 1).

THeOry OF OPeraTiOn
The idea behind the development of the
Stacked Washer/Dryer was to have a product with a small enough footprint that could deliver the same washing and drying capability as well as load size of the freestanding washer and freestanding single dryer in half the area.
Combining payment systems and operating with a single coin drop and single coin box adds to the simplicity as well as keeping the cost of ownership down.
Commercial Stacked Washer/Dryers may or may not require a payment system to operate.
If required, once payment is established, following the instructions on the console leads the user through the procedure for selecting a cycle to care for particular fabrics. After a cycle has started, the display will show the selected cycle as well as the countdown of the time left in the cycle.
With a Smart Card system, after a valid card is inserted, a choice to turn on the washer or the dryer is given. After the selection is made the appropriate payment is debited from the user’s card. With a coin system, the value of a wash or a dry cycle needs to be added before either cycle will be made available. The cost of the dry and the wash cycles shown on the display will decrease with each coin entered. With a dry cycle set for less than the wash cycle, the display prompts the user to select the dry cycle or add additional coins for a wash cycle.
There are 5 fabric care selections available and a QUICK WASH selection available for the washer. All selections are preprogrammed at the factory for optimum water temperature and spin speeds by fabric type.
Water levels are also factory set and not adjustable by the user or the owner.
Dryers have 3 fabric care settings and there is no cycle available for drying without heat.
All dryers are factory preset to allow for 2 minutes of cool down at the end of a cycle.
Any time added at the end of a cycle (Top-off) will include 2 minutes of cool down time. Any dry cycle started as free vends or OPL will be cancelled if the door is opened during the cycle and a complete cycle will need to be restarted to finish drying the load.
The maximum time selectable for a dry cycle is 99 minutes. Coins entered after 99 minutes is displayed will be held in escrow for a limited
(owner selectable) time, and can be used for a subsequent dry or a wash cycle. Additional coins entered after the total needed for wash cycle will also be held in escrow for a limited
(owner selectable) time, and can be used for a subsequent wash or a dry cycle.
Communication with the user is important and the display will advise the user if a washer was
‘UNBALANCED’ or if the user has added too much detergent (SUDS). At the end of a cycle if the wash cycle was aborted and finished without completing the entire cycle, one of the aforementioned messages will appear on the display. The message will remain on the display until after the door is opened and an additional 2 minutes has elapsed.
This provides adequate time for the user to determine that the load did not complete as expected and to view the message on the display. The following or subsequent wash cycle will not be effected by the previous load unless the residual detergent is left in the washer and or the next user adds too much detergent as well.

TyPiCal CyCle OF OPeraTiOn
When WHITES AND COLORS is selected, the high heat cycle is activated. The high temp cycle uses the circuit that involves the 155°F setting of the exhaust thermistor.
When the cycle type is selected on PD models the dryer motor circuit is energized. The motor has power sent to both the Run and the Start windings. When the motor reaches run speed the centrifugal switch snaps closed and the switches in the motor switch change position.
Motor switch 5M continues to power the main motor winding but the switch contact to the
Start winding is opened, which drops the start winding out of the circuit. At the same time motor switch 1M closes to motor switch 2M which allows the circuit to close, completing the heater circuit. Now the blower, the drum, and the heat are all working.
Notice the components in this gas heat circuit; heat can be shut off by opening any of the inline components:
1. Thermal Fuse
2. Exhaust Thermistor
3. High temp cutout
4. High temp thermostat
5. Motor Switch 1M to 2M
6. Gas Valve Coils
Using this same theory we can show that if there is line voltage showing at the 2-pin connector for the gas valve, then all of the thermal components are closed and OK! We would also know that the motor switch 1M to 2M is closed as well, because the neutral side of line voltage must pass through this motor switch that is only closed if the motor is running.
With Electric heat models, as with gas heat models, when the motor reaches full speed and the centrifugal switch trips, the switches change state, although with electric heat models full line voltage (208-240volts) is supplied to the heating element when the motor switch M1 to M2 is closed.
3-11
The belt switch is in series with the motor and has one of its leads connect directly to a terminal on the motor thermal overload. If either the belt switch or the motor thermal overload opens the circuit, it will stop the motor, which In turn will cause the motor centrifugal switch to open and change the positions of the motor switch, opening motor switch 1M to 2M, which causes an open in the neutral in the gas coil circuit and L2 of an electric element circuit.
Door switch on this dryer is not wired in series with any other components. When the door switch is opened or closed it is the User Interface Control that senses this and activates or deactivates the relays on the board. Whenever a door switch state is sensed as closed the UIC allows the Select
Cycle or Reselect Cycle to display on PD or
PR models after correct vend price is applied.
On PR models set-up for free vend the display would show Select Cycle after the door switch state is changed and then detected as closed.
With all pay for use commercial dryers, whenever the power is supplied to the dryer and the cycle has been started, time continues to count down even if the cycle is interrupted by the opening of the door switch.
Dryers set for On Premises Laundry (OPL), set for free vend; when a cycle is interrupted with a door opening or power failure, that cycle will be cancelled, and a new full cycle will need to be started if additional dry time is required.

unDerSTanDinG THe GaS valve anD iGniTiOn SySTeM
The sensor, ignitor and gas valve are interrelated and function as the ignition and heat source for gas dryers. At the start of the cycle the radiant sensor contacts are closed, the ignitor is at room temperature and the gas valve is closed, blocking the flow of gas. In the wiring diagram below, the radiant sensor contacts are wired in parallel with the gas valve secondary coil. This bypasses current around the secondary coil when the radiant sensor contacts are closed. Therefore valve
#2 cannot open as long as the radiant sensor contacts are closed.
A significant voltage drop develops across the secondary coil, which renders both the booster coil and the ignitor ineffective due to their low resistance and the reduced voltage available, even though they are still in the circuit.
Radiant Sensor Contacts Closed
The holding coil, the booster coil, and the ignitor all receive line voltage. The holding coil and booster coil open gas valve #1. Gas valve
#2 is still closed, prohibiting gas to flow to the burner. The ignitor, operating at line voltage, begins to get very hot (as the ignitor gets hotter the resistance of the ignitor drops). The ignitor glow radiates heat to the radiant sensor and as long as the radiant sensor contacts are closed the secondary coil of the gas valve #2 are bypassed.
Radiant Sensor Contact Open
The ignitor is now very hot and valve #1 is open. The radiant heat from the ignitor causes the contacts in the radiant sensor to open.
With the radiant sensor contacts open the secondary coil of the gas valve is no longer bypassed. The secondary coil is now in series with the parallel circuit combination of booster coil and ignitor.
The booster coil and the ignitor are wired in parallel, although they are still wired in series with both the radiant sensor and secondary coil combination.
When the radiant sensor contacts are closed, full line voltage is available to the booster coil and to the ignitor. When the radiant sensor contacts open, the current has to flow through the secondary coil on gas valve #2 in order to get to the booster coil and the ignitor.
3-13
Because of the relatively low resistance of the hot glowing ignitor, most of line voltage is dropped across the secondary coil. The remaining voltage is dropped across the booster coil and ignitor. The secondary coil now opens gas valve #2 allowing the gas to flow through both valve #1 and valve #2 to the burner where it comes in contact with the still very hot ignitor and the flame is ignited. nOTe: Since the ignitor will begin to cool, the tip of the ignitor is left in the flame to keep the resistance low enough to keep the secondary coil powered, which keeps the gas flowing and the flame burning.

every load cleaning:
The lint screen is located in the door opening of the dryer. A screen blocked by lint can increase drying time.
To clean:
1.
Pull the lint screen straight up. Roll lint off the screen with your fingers. Do not rinse or wash screen to remove lint. Wet lint is hard to remove.
• iMPOrTanT:
Do not run the dryer with the lint screen loose, damaged, blocked, or missing. Doing so can cause overheating and damage to both the dryer and fabrics.
• If lint falls off the screen into the dryer during removal, check the exhaust hood and remove the lint. See venting requirements
(Document Links Page).
as needed cleaning:
Laundry detergent and fabric softener residue can build up on the lint screen. This buildup can cause longer drying times for the clothes, or cause the dryer to stop before the load is completely dry. The screen is probably clogged if lint falls off while the screen is in the dryer.
Clean the lint screen with a nylon brush every
6 months, or more frequently, if it becomes clogged due to a residue buildup.
To Wash:
1.
Roll lint off the screen with your fingers.
2.
Wet both sides of lint screen with hot water.
3.
Wet a nylon brush with hot water and liquid detergent. Scrub lint screen with the brush to remove residue buildup.
4.
Rinse screen with hot water.
5.
Thoroughly dry lint screen with a clean towel. Reinstall screen in dryer.
2.
Push the lint screen firmly back into place.

Each washer comes from the factory with a “U” Bend fixture to be used on the drain hose end that fits into the stand pipe or over the sink edge. The “U” Bend needs to be fitted to the drain hose at the very end with no more than 2 inches of the end of the drain hose extending past the end of the “U” Bend. Secure excess drain hose to plumbing or another structure to avoid having the drain hose rubbing or bouncing on other surfaces, which could cause wear of the drain hose and leaks.
TeCH TiP: Do not insert excess drain hose into a stand pipe. This will cause siphoning of water out of the washer and down the drain during the fill process, which can result in a F20 code.

TeCH TiP: If the latch has been tripped, with the door open, by something being poked into the latch, it must be unlatched before the door will be able to be closed again. There are two ways this can be done:
1.
Remove the door lock assembly and turn it over to view the back of the latch mechanism.

8.
Disconnect 4 wire connectors attached to the door lock assembly. The top connector has a locking tab to release, and one of the connectors in the middle is a Rast connector with a locking tab to lift.
nOTe: In case of a power failure, the latch should unlock automatically after 2 minutes, but if not, the door can be opened manually by removing the washer lower service panel and reaching up to pull down on the manual release tab at the bottom of the door lock assembly. A reason for the lock not self-opening after 2 minutes would be if the power interruption occurred prior to 2 minutes of cycle time, which would not allow enough time for the wax motor to energize and extend completely.

COin DrOP aCCePTOr
The coin drop acceptor is used only on the
PD model washers. This is a mechanical coin drop assembly with a coin sensor attached.
In normal use, occasional cleaning in hot water is all that is needed to maintain reliable operation of the coin drop acceptor. The coin drop does not need to be oiled, as it will only cause dirt and dust to collect or build up. This can disrupt the operation of the acceptor.
The coin sensor is mounted to a bar located at the back of the coin acceptor. There is a window period for a coin to pass the coin sensor. If the coin fails to pass through at a certain speed, the microprocessor may assume the washer is being tampered with or it is a non-valid coin. The washer will then go into a standby mode and will not accept coins.
The coin sensor is set in position at the time of manufacturing for the proper reading of coins.
The coin drop assembly checks the diameter, thickness and magnetic properties of the coin.
There is a coin return button that can be pressed if the coin jams in the coin acceptor.
When it is pressed, the button presses against a tab which is pushed to one side spreading the coin acceptor plates apart. This allows the coin to fall and roll into the coin return bail area. The face plate has a coin bail (arched area for the coin) which is located at the base of the coin return slot. The face plate can be removed from the coin acceptor by removing the two screws from the back side of the face plate.

Burner iGniTOr ManOMeTerS
When the dryer control calls for heat, line voltage is applied to the ignitor. The ignitor will heat up quickly and glow as it reaches approximately 2200°F in about 30 seconds.
Gas contacting the ignitor at this temperature will ignite immediately.
Insufficient gas flow can cause problems.
Therefore, checking the gas pressure at the time service calls are performed may avoid a return call.
1.
Unplug dryer or disconnect power.
2.
Turn off gas supply to dryer.
Gas pressure can be checked with an instrument called a “manometer.” This device can detect a “low” LP tank, restricted gas flow, bad gas valve, a malfunctioning pressure regulator, too many gas appliances operating off of a small supply line, or an improperly converted appliance from Natural to LP gas.
3.
Remove gas burner ignitor
(See page 4-83).
4.
Disconnect ignitor wire connectors from the main harness connector.
5.
Set the ohmmeter to the R X 1 scale.
Set digital ohmmeter to lowest scale.
Other types of manometers exist; however, the type of manometer we will discuss in this manual is a water tube with a glass tube inserted into it. Water is added to the outer tube and it rises within the inner tube to equalize and seek its own level, the same method is used in both arms of a “U” shaped tube Manometer.
6.
Touch ohmmeter test leads to the 2wire connector pins. The meter should indicate between 50 and 250 Ω at room temperature.

A flexible rubber hose is connected to the upper, open end of the manometer and to the gas source. Gas pressure is exerted on one of the water columns, pushing it down. The water level then rises in the other column.
The pressure is then read on the manometer as the water column pushes downward.
The water column (W.C.) for a Maytag dryer is
3.5” W.C. for Natural gas and 11” W.C. for LP gas.
