Siemens dishwasher constantly filling with water

Have an elderly Siemens dishwasher (no visible indent plate) that until I moved it from under its worksurface last week worked fine.

Having moved it back into place I find that the cold feed does not stop, i.e. it is constantly running into the unit as if a valve is open.

Advice please on where to look and for what.

TIA

just a guess, there should be a tube, up which water rises as it fills, this triggers a sensor when the pressure rises to a pre-set level. This can get blocked and therefore fail to cut off - so the machine carries on filling. This happens in washing machines, and I'm guessing it could be the same problem,

Do you mean it is filling up with water when not in use or it is overfilling when in use and flooding the kitchen ?

Filling when I open the tap on the main CW feed - irrespective of power state of DW, i.e even with power off.

I'll investigate the filler tubes - there's a blow moulded plastic thing on the LH side with a series of vertical tubes which fill and empty when the DW is working properly. It is rather mucky at hte top but I do not think it has any pressure sensing capabilities. The level sensor is, I suspect, on the other side or in the door of the unit.

But as the fill continues despite absence of poer I suspect that a valve is open somewhere. Why this should happen after being moved I have no idea.

It can only be a faulty valve or poor water pressure (water pressure keeps valve closed) perhaps if you disconnected the water feed you disturbed muck in the pipes and this has gone into the valve stopping it sealing closed. The valve at fault will be the one the water feed pipe screws directly to inside the appliance.

I would suggest taking a look at the Hanes manual for washing machines. It explains in great detail how the valves work, it only takes a small amount of grit to block a pressure balance hole in the valve and then they start dribbleing.

Thank you both. I'll attack the valve closest to the inlet. I had wondered about dirt. Water pressure is high and the unit fills relentlessly, i.e. not at a dribble.
