Hi,
Having recently fitted a temporary kitchen - so we now have some work surface, a usable sink and some where to park the white goods I connected up the dishwasher.
It is only a couple of years old and was last used about a year ago when we were in Scotland.
It was transported along with our other stuff by ourselves in our Luton van.
So, when connected up it refused to work, the sump filled up with water and wouldn't drain - I had to pump it out with a little hand pump I bought recently on spec at Lidl!
The salt container also had water in it so got the same treatment. Having looked on line I couldn't find info on our specific model but did find out how to dismantle the machine.
The indicator panel indicated 'Check Water' all the time as well.
Sometimes it would drain the sump but generally wouldn't wash or do anything it was supposed to.
I guessed it was a sensor somewhere as the drain pump was fine and no visual indication that anything was amiss.
To cut a long story short after working out how the thing operated I checked the water inlet flow sensor. This consisted of a plastic whell with small magnet attached which rotated when water entered the filling system. The magnet operated a reed switch - feeding back pulses to the processor/programmer.
I easily removed the small PCB that held the reed switch and checked its operation with a magnet, it was very inconsistent - sometimes not working at all.
Unable to find any reed switches among my spares I purchased one off Ebay. I wasn't sure whether it was a NO or NC or whether it really mattered so I bought a changeover type to be sure.
On de-soldering the original switch one end was loose - it was cracked, obviously the cause of the problem. I soldered the new switch in NC configuration and refitted the PCB and tested the machine. Worked perfectly! I wonder how the reed switch was damaged or maybe it was faulty from new?
Anyway a cheap repair - only a few quid for the replacement switch!
