WET STEAM AND/OR DETERGENT PUMP DOES NOT RUN:
1.
Inspect if the command on the hose enables the wet steam or detergent pump
or not (runs only when steam output is enabled). Test with an identical hose that is
known to work.
1a. Check all electrical connections and the switch in the grip and repair
or exchange.
2.
Inspect the electric connection in the socket and repair if faulty.
3.
Inspect the pump (the coil can blow or the pump can jam), hose and water filter.
3a. Remove coagulated detergent from the detergent hose and pump and
exchange parts if necessary.
4.
Make sure the LED on the wet steam / detergent PCB light up correctly, otherwise
it is faulty or wiring is.
ATTENTION:
In case of a faulty wet steam/detergent PCB always first inspect the
small pumps to exclude a short circuited pump coil before replacing the small
PCB, otherwise the new circuit board will immediately blow due to overvoltage
from the coil.
WATER TANK LEVEL SENSOR GIVES NO SIGNAL
1.
The water tank has two level sensors MAP0120/NEW, one for low level and one for
tank full level. If you run out of water without the machine stopping steam output
with an audible acoustic signal, then inspect this sensor and exchange if faulty.
(see picture 14)
2.
The sensor is electromechanical and may be jammed. Put you hand into the water
tank and find both sensors. Move them gently to make sure they are free to move.
If they are then check all cables and connections and if nothing is loose exchange
the faulty sensor.
