This is a weird one… customer reported that it stopped working.
Found that there was an issue with the door catch which I managed to resolve it. The drain pump is responding and emptied the tank, then it proceeded onto fill which it did for one second.
The water did come through as the turbine did spun only for a second or two then went silent, I replaced the contact reed to see if this would resolve it also increased the water pressure as the inlet tap wasn’t fully open.
Still nothing, all it does drains then fill for one second then silent. No error codes. The info projection light is broken as there is no information other than one full white blob.
The fascia panel are responsive, and nothing appears to be hindering. No leaks another than old leak from 2 years ago when customer accidentally filled the salt chamber with detergent which was replaced by Neff engineer at the time.
Any thoughts? I need the solution as the customer’s dad is a commercial dishwasher repairer and is looking down on me….
that sounds like a board fault
when turbines fail it fills for a lot longerthe only long shot is the cold valve coil is going open after a second but its a very long one
assume if you reset its repeatable
take out main pcb. check connections to valve and look for damage

Have you checked the valve 11033896 on the side of the heat exchanger (a common failure) as it sounds like it may be trying to empty the exchanger tank and failing.

The dreaded e19 fault? I do have the drain valve, come to think of it I did notice that the tank didn’t drain completely (thank you, Jem) and it has some standing water inside the heat exchanger. I will try this one then check the board to the valve(?) – it’s very rare if not in my case never had to replace aquastop if that what you are referring to Dave?
The flaming dishwasher is 3 years old. Why is it that new dishwasher especially Bosch/Neff/Siemens test my mettle?
have had aqua stop valves go but normally is not the coil that fails, it normally has slow flow. Its also poss when the valve energises it has normal flow then stops due to diaphragm damage. Was looking for long shots as its always the unusual faults that stump you
the one way you can be certain its not a valve fault is to check for voltage going to the valve

“the one way you can be certain its not a valve fault is to check for voltage going to the valve”
Not sure you mean that?

forgive me… how to do you check the voltage and where (the module side?)? The cable is very thin, just saying…
