The water cycle always starts at the tank and first look at the transparent filter behind the side panel. If it is dirty, pull it off and rinse it against the normal flow direction until it looks clear again. If it is not the right one, check the hoses up to the pump... |
Thanks for the answer!
I removed the side and back panels, took out the water connection of the tank, cleaned it and put it in as it was. The tank could not be pushed in effortlessly to the stop, so I removed lime from the surfaces and took away some plastic in front of the microswitch so that the tab would fit better to the lever.
Then I removed the 90° plug to the water hose in the machine from the tank connection to the flowmeter including the hose, the flowmeter and the next hose to the pump, cleaned it and put it back in. There was a lot of black dirt in the 90° piece, bah! I replaced the membrane switch on the pump and then reassembled everything again.
In test mode, the two valves click happily and on command, sounds healthy so far. The pump, however, does nothing at all except a super-short electrical hum. Definitely not moving.
The crazy thing is, when I turn on the machine in the morning I usually (1) get coffee without any problems. If the box stays switched on for a longer time, the message "water circuit empty" (2) appears and then it doesn't go away again. Possibly I have here 2 problems that overlap ... or it is haunted somewhere in the electronics (that is guessed).
to (1): If I have a problem in the morning, he says "Insert tank". If I push the tank firmly into the bottom front and/or knock on the side wall behind the tank, it usually works again. The pump starts up and there is coffee.
to (2) In this situation the pump does not start anymore. The machine wants to pump hot water, it also heats, but at most something boils out but without the pump's involvement.
How can the pump run sometimes and sometimes not ... I don't get it. At the moment there is no water in the pressure hose that goes to the pump, there is no water in the feeding hose either. So the water circuit is really empty and the pump does not pump.
