TROUBLE SHOOTING
•
NO COFFEE:
WHEN TURNING THE SELECTING BUTTON TO MAKE COFFEE, NOTHING IS HAPPENING.
- Check if there is water in the tank (the water lack light may be burnt out)
- If there is water, control the functioning of the water lack microruptor ref. PN0340. By pressing
and raising the tank, the light must be extinguished and enlightened.
- Check the microruptor of the distributor ref. PN0340. It must start the pump ref. PN0620 and open the
electrovalve ref. PN1310.
•
COFFEE QUALITY:
- Check the temperature adjustment, coffee must not be too cold ("white") or too hot ("black")
without cream
- Control the pump flow, it's necessary to get at least 10 cl in 20 seconds
- Check the 3-way electrovalve ref. PN1310 ; if it leaks during infusion, the pressure goes down
and the overflow tray is untimely filling.
- Check there is no water going back to the tank during infusion, if it is the case that's a leak of
the distributor decompression valve.
The infusion pressure is going down and the coffee quality too.
- The heat exchanger ref. PN1290 is partially blocked, the passage is reduced, the flow decreases,
the thermic conduction is less good.
- Check the fringe filter of pump sucking ref. PN0650 in the tank.
Coffee is completely cold.
- The heat exchanger does not heat any more.
- Check the heating element ref. PN1290
- Control the thermofuses ref. PN1750 or PN1751 (blue wire) and ref. PN1752 or PN1753
(brown wire)
- Check the probe ref. PN1250, the temperature control card ref. PN0490.
•
NO HOT WATER:
WHEN TURNING THE SELECTING BUTTON TO PRODUCE HOT WATER, NOTHING IS
HAPPENING.
- Control the same points as when it is not possible to make coffee, i.e. water in the tank,
tank microruptor ref. PN0340 and microruptor ref. PN0340 of the ceramic tap.
NO STEAM:
* If the boiler is hot, but nothing is going out:
- Check the steam switch ref. PN0950
- Check the pump ref. PN0890
- Check the fringe filter of steam pump sucking in the tank
- Check if the electronic circuit ref. PN0510 is sending pulses.
- Check the 3-way electrovalve ref. PN1310.
