Went to this machine today. After selecting a program and pressing start the machine drains starts to take in water for a second or two then stops and the check drain check inlet flashes. I have checked the filter at the inlet valve, and a good water pressure from the plumbing supply. I have a good ohms reading at the water valve. I have checked the wiring loom for any breaks in the door. The voltage to the water valve cuts out after a second or two. Is there anything I have missed as I suspect the control module. Any replies are much appreciated.

As this one got a reed switch in the matrix on the side? If so sometimes the wheel sticks in the matrix or the reed switch may be faulty.

Hi I have checked the reed switch, should there be a resistance between the terminals. Its open circuit at the moment?
Re: Miele Dishwasher G645 SC Plus
Not sure if it is meant to be open or closed circuit to be honest.
Try putting a magnet near it if it switches you know it is ok.
It’s usually the wheel that spins in the matrix which the reed switch counts that sticks.Phil
Re: Miele Dishwasher G645 SC Plus
Have had the wires to the reed switch break under the door, so check for continuity back to the PCB
Re: Miele Dishwasher G645 SC Plus
Checked the reed switch continuity which was OK. I also jumped out the level switch which is in the circuit but same fault. It looks like the control module as I don’t think there is anything else in the circuit for water intake valve. I have tried a new reed switch.
