Good evening,
I am having issues with the above dishwasher. Apx 3.5 years old. Started intermittently a few weeks ago now won’t complete a cycle.
Story goes. Machine will start as normal, drain, then fill with water. About 3/4 minutes in it stops and starts to drain water to the tray on the underside of the unit (I assume this is a flood protection system, please correct me if i am wrong). The machine will then emit a warning tone (3 beeps) at me and continue emptying water via the two overflow tubes underside. Sometimes during checking today the machine will stop and only beep once (1 tone).
I have cleaned all the filters. Dryed the water out of the undertray. Ensured the drain pipe is free, not kinked and is clear at the drain connection under the sink. It also once this evening ran the drain pump continuously until the power was isolated.
Can anyone point me in the right direction please .
Many thanks
Update
On closer inspection the two overflow pipes that are draining water into the tray seem to be exactly that. They are attached to small drains under the door.
My question is now what tells the board when enough water has been loaded into the machine? I can’t see a level sensor anywhere.
Is there a workshop manual available anywhere other than the operation manual I have downloaded from Manuals lip?Many thanks
there is a pressure switch mounted on the side of the sump

Hi Dave
I have attached the pnc number below. There is a sensor that sits in the sump. I have cleaned around it just incase of a build up of limescale etc.
To add. The machine started faulting by only beeping once and the bottom of the machine was full of water (not drained). Once reset the pump would run and drain and usually run a full cycle ok.
