Zanussi dishwasher problem

[Burnerman]

I don't really know what I'm doing here, but a neighbour has asked me to have a look at her DW 908 dishwasher.
From what I gather it wouldn't fill with water.
The solenoid fill valve seems to have some sort of anti flood device built into it....when I got to the appliance the solenoid coil seemed to have a reading in the megohms area.
On disconnecting the machine and looking further, the resistance of the coil has fallen to around 3.6k ohm - as if something has reset itself.
Can anyone enlighten me as why it could have tripped out in the first place? The machine is running happily at the moment with a rigged up water supply, and the water is heating.
Thanks for reading!

Sounds like an older anti-overflow valve (pre-aquastop). Around 4kohm is about right for the coil. There is a breather tube attached to the valve, if this gets clogged it can cause the problems you experienced.

Most kind of you to reply...I think (hope) I've sorted it.....
Basically I removed all of the tubes from the sump area, and blew through them - there was a possibility that a pipe below the large filter may have been blocked.
Anyway, I was rewarded with a faceful of gunge from the filthy bowels of this machine (always catches you on the lip, doesn't it) and the thing has done 4 trial runs faultlessly. So, reinstalled back with its owner.

Curiously, I can feel my jaw starting to lock
Unbelievable grot inside a machine thats designed to clean things

Dishwashers can be really gross...especially one that has clogged & stood for a week or two. Handy to have some of those paper airline bags in your toolbox
