I see what you mean. It still may not be measuring the flow correctly. I took the panel off the door and checked continuity at the pcb so the wires and connections are all ok. I measured continuity across the reed switch again while it was running and it does pulse a little between short and slightly longer beeps. I will see if I can get another reed switch to try it.

Thanks again for your help.

I have to apologize for the time it’s taken to reply but I had to give in to pressure from the other half and buy a new dishwasher! I wasn’t too keen on giving up on a nearly new dishwasher so I put it in storage until I had time to look at it again. I had some time today so I took the reed switch out and tested it with a Magnet and a multimeter and it was working ok. I put it back on the machine and tested for continuity while it was running and it was giving fast intermittent beeps as you might expect as the magnet spins when water is coming into the machine. I held the probes on until the water stopped flowing in. (About a minute and a half or so) About 20 seconds later it stopped on fault again. It seems like the reed switch is working ok.

I’m not really sure what to try next?

So it’s not the inlet valve. Fitted the new one and it’s still the same.

Thanks for the info Dave. I will see if I can find something like this or figure out how it senses water. If anyone has any experience with Montpellier dishwashers I would be grateful for any info.

Many Thanks

I couldn’t find a pressure sensor. If I activate the safety float switch during a cycle it shows a water overflow fault code. If it was overfilling or flooding wouldn’t it show this code rather than the inadequate water supply fault code?

For now I’ve ordered a new inlet valve as I’m not sure if the flow is good enough or not. I’ll let you know how that goes.

Thanks for your help so far.

Thanks for your reply. I checked the float for obstructions and it seems ok, the float is nowhere near the switch, I also checked for continuity across the switch and it seems fine. If I press the micro switch at any time, (even with the program selector switch off) the discharge pump runs. I removed the hose from the top of the float and checked for obstructions and during a cycle there is no water in the hose at any time. As far as I can tell it seems to be working as it should?

I’m not sure what I should check next?
