3.3. TEMPER ATURE CALIBR ATION


The Ecoboiler control PCB (1600345) has the ability to have the desired set-point temperature at whatever setting is required. During manufacture of the PCB it is set to the default temperature of around 95°C.

If the temperature setting needs to be modified on-site please follow the steps below:

1. To Enter Calibration mode: a. Turn the machine off at the mains power supply. b. Then, whilst depressing the tactile switch on the PCB, turn the mains power back on. c.

All available LED’s on the front panel will now blink continuously. d. The machine is now in Calibration mode.


2. In Calibration Mode the machine will heat continuously until the tactile switch on the PCB is pressed for a second time (NB: The tactile switch should be pressed for at least 1 second)

3. Using a thermometer to measure the temperature at the thermistor pocket, the machine should be allowed to reach the desired set-temperature. (NB: It may be necessary to let the unit cool down if the desired set point is lower than the units current temperature)

4. Following a correct calibration procedure the tank temperature should be maintained within

3°C of the desired set-point temperature.

In the event of an incorrect calibration process the steps below should be followed:

5. If the tactile switch is pressed too early and the temperature is set lower than desired, the tester should simply repeat calibration.

6. If the tactile switch is pressed too late and the set temperature is too high, the tester will need to wait for the temperature in the tank to cool, or add cool water, and then repeat calibration.

Ecosmart UC4L /Ecosmart UC10L

PLEASE REFER TO INSTRUCTION BOOKLET FOR TEMPERATURE CALIBRATION.

3.4. TIME/VOLUME DISPENSE C ALIBR AT ION


1. Open the service panel.

2. Make sure that the machine is powered, filled and heated (ready lamp green).

3. Press calibration tactile button on the PCB for a second until status lamp starts blinking red-green.

4. Set new dispense time by pressing dispense button to obtain the required output volume of water.

Button may be pressed several times – all times / volumes will be added together.

5. To confirm and save new value press calibration button on the PCB for a second until the status lamp stops blinking.

6. S etting dispense time / volume to zero (omit step 4) will make the machine work as “push & hold”

(water dispensed as long as the button is pressed).

3.5. TROUBLESHOOTING

3.6. M AINTEN ANCE:

Marco machines have been designed to give many years of trouble free service. Marco Beverage

Systems manufacture and test to ISO9002:2000 standard. The only regular maintenance required is occasional de-scaling.

Descaling Procedure:



Isolate machine from power supply.



Isolate machine from water supply.



ALLOW TO COOL COMPLETELY!



Drain water from machine.



Remove all lids.



Remove as much scale as possible by hand, paying particular attention to level probes (White plastic with steel tab). Be very careful not to damage any attachments.



Use ScaleKleen, Marco part No. 8000270 or similar. Follow instructions carefully.



Thoroughly clean and flush the machine before re-use.



Follow installation and first time operation instructions

3.7. CLE ANING:

The exterior of these machines may be cleaned with a damp cloth and a light detergent. Do not use abrasive cloths or creams, as this will spoil the finish of the machine. Do not use a water jet or spray.

Beware of accidentally operating the draw off tap or push button when cleaning the front of the machine.

3.8. LIMESC ALE:

In common with all water boiler manufacturers, service calls resulting from limescale are not covered by warranty. Fitting a scale reducer is recommended, especially in hard water areas. This can reduce the build-up of scale but may not stop it altogether. The frequency that descaling is required depends on the local water supply; hard water areas need more attention. A scale reducer can reduce the build up of scaling, but may not stop it altogether. Descaling of the machine should ideally be carried out by qualified service personnel.

3.9. C AUTIONS AND SAFETY TIPS:



This appliance must be earthed. If the moulded plug supplied is not used then ensure that the green/yellow cable is connected to a suitable earth.



Risk of flooding. The hose supplied with this unit is non-toxic food quality tested to 190psi.

However, a hose is not a permanent connection. It is, therefore, advisable to switch off boiler and close the stopcock valve when boiler is not in use, e.g. overnight, weekends etc.



Risk of scalding. Beware of accidentally operating the water drawoff tap especially when cleaning the front of the boiler.



The utmost care has been taken in the manufacture and testing of this unit. Failure to install, maintain and / or operate this boiler according to the manufacturer’s instructions may result in conditions that can cause injury or damage to property. If in any doubt about the serviceability of the boiler always contact the manufacturer or your own supplier for advice.

4.6. TROUBLESHOOTING – DIAGNOSTIC GUIDE:

NOTE FOR THE ECOSMART RANGE IN ADDITION TO THE STATUS LED FLASHING TO

INDICATE AN ERROR

– THE DISPLAY WILL ALSO PROVIDE INFORMATION

2 FLASH CYCLE – BELOW LOW LEVEL

Display pattern:



2 flashes then a short pause - repeated.

Electronic check and action:



This indicates that the low level circuit is open i.e. the probe is not in contact with the water.



The element is switched OFF at this stage and the inlet is left ON.



(note that if this is a low probe wiring fault, the water will stop at the high level probe regardless of the status of the low level).



This is a recoverable error i.e. the machine does not need to be reset when the problem is solved. (e.g. if a closed mains water stop valve is the problem, opening the valve will allow water into the machine and normal function will resume when the low level probe is reached)

Probable causes:



The water level is below the low level probe, which is normal when the machine fills for the first time. (Can be flashing for up to 2 min at start up)



The low level probe wire is disconnected, or there is another wiring fault



(eg. a bad earth (return) connection between the PCB and the Tank)



Check that the water pressure is OK and ensure that the stop valve is Action required: open.



Check that the inlet solenoid is working.



If the water level is above the level of the low probe, check the probe circuit wiring

3 FLASH CYCLE

– THERMISTOR OPEN CIRCUIT

Display pattern:







This indicates that the Thermistor is measuring such a large resistance that it assumes the thermistor circuit is open.



The element and inlet valve are turned OFF when this error is detected



This is a recoverable error. When the correct range of resistance is measured, normal operation resumes

Probable causes:



The thermistor probe is unplugged from the 4way connector on the PCB or the thermistor has failed open circuit.

Action required:



Check that the thermistor is plugged in to the PCB correctly. If it is, replace the thermistor.


4 FLASH CYCLE – NOT HEATING

Display pattern:







This checks that the temperature is increasing when the heater is on.



Measures the rate that the temperature increases in a specified time.

This error is only displayed after 20 mins of the heater being on continuously. When the error is detected, the element and inlet valve are turned off.



This is a non recoverable error. The machine needs to be reset when this problem is solved.

Probable causes:



The elements have failed



Wiring fault

Action required:



Check that the resistance on the elements. If there is a reasonable resistance (1525Ω)on the element it probably has not failed, so the wiring might be at fault.

5 FLASH CYCLE

– THERMISTOR SHORT CIRCUIT

Display pattern:







This indicates that the Thermistor is measuring zero resistance. It assumes the thermistor has failed sort circuit.



The element and inlet valve are turned OFF when this error is detected



This is a recoverable error. When the correct range of resistance is measured, normal operation resumes.

Probable causes:



The thermistor has failed.

Action required:



Replace the thermistor.

6 FLASH CYCLE – NOT FILLING

Display pattern:







This checks that the water in the tank cools when the inlet solenoid valve is switched on.



This is a non-recoverable error. This checks that the water in the tank is cooled by when the inlet solenoid valve is opened. If the water pressure is within the specifications (5-50psi), the inlet solenoid should not be on for more than a few seconds. If this water temperature has not decreased by the required amount



(1 degree per minute), the inlet solenoid is switched off and the 6 flash cycle is displayed.

Probable causes: 

Mains water pressure problem or the mains water stop valve is closed.



Inlet solenoid valve failure.

Action required:



Check the mains water supply. (Note: Temporary loss of water pressure can occur in certain sites

– particularly when various machines are plumbed to the same mains water supply.) If the water supply is ok, reset the machine (switch the machine Off and On again). This will reset


the error and if the water supply is ok, the machine will return to normal operation.



NOTE: If the water supply is the problem, ensure that this is rectified or this error will re-occur.



If there is no problem with the mains water supply, check that the inlet solenoid valve is working.

4.7. Tank Components

The tank internals are detailed below. Care should be taken when cleaning inside the tank.

The level probes provide much of the control inputs into the PCB and are critical to the operation of the machine. The wiring to these should be checked regularly and the probes themselves should be cleaned whenever the machine is serviced.

There are 3 level probes on the 10L Ecoboiler versions and 2 level probes on the 4L versions.

4.8. Descaling Procedure

To descale the machine thouroughly:





Unplug the machine.

Disconnect from the water supply.







Drain as much water from the tank as possible.

Remove the lids and allow the machine to cool completely.

Drain all the water from the machine.
