Blomerg Dishwasher sensor in lower door?

[Twoten]

Called to a Blomberg LDV02284 slimline dishwasher tripping electrics.
After a while of hunting, I found the insulation fault in what appears to be a sensor mounted on the right-hand side of the support bar inside the lower section of the door.
It’s connected to a blue and a white wire which goes back to the PCB.
I can’t find it as a spare on its own, but it appears to come as part of the complete cable harness.
Can someone tell me what this is, is it available as a separate part and what causes this to get wet?

possibly?

Thanks, Dave,
It pointed down, but looked like it was pointing into the overflow channel where there’s a lower lip in the front edge of the tank. I should have taken a photo or opened it up to take a closer look. I thought I was going to find it as a spare and identify it that way.
If it was an LED I would have thought it would be available as a spare.
I think I’ll have to go back and strip it down.

have emailed you the wiring diagram as i could not see the colours you mention

since you may be able to trace it back to a plug on the board you may get an idea from that

It sounds like it is the floor illumination LED – I have seen several of these cause this problem, usually the customer doesn’t want to replace the harness so I just cut it off at the PCB and the machine works fine.

I’m going to go back and take another look. If it is the LED indicator I was going to talk to the landlord. My guess is they will probably go for this option particularly if it could go again at a later date.

Thanks for the wiring diagram Dave.
It looks like KN8 terminal 5&6 marked lower LED. It’s not showing any wires from the terminals though.

all you can do is trace the wires and see where they go and take it from there

I’ve changed one under warranty yes they are a pain to fit and it doesn’t come with the harness I’m nor 100{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} but I think [h=3]1767140100 is the part number[/h]
