Bosch SGS46E02GB/75 dishwasher check water

[allan]

Hi hoping someone can help me with this as I don’t have a lot to do with dishwashers, this bosch dishwasher had the check water light on, pump kept running even if door was opened, there was no water in the base,I replaced the jug impeller and all has been ok for about a week, customer phoned to say it’s doing the same thing again! Any ideas where to go next?
Thanks Allan

Check the pressure chamber in the left hand side, these gunge up which causes the water entering the machine to back up and activate the anti flood / overfill switch which can sometimes get jammed in the activated position.

Is that to the right side of the water matrix? Thanks

Yes, it is front left of the machine, you will see a red rod coming up from the base, this is from the anti flood float and the switch that it activates is also the overfill switch.
