Neff S517T80D0G/33 dishwasher left with water in the bottom after the end of a cycle. There is no issue with drainage, no blockages, or returning water. No fault codes displayed. Diagnostic cycle runs ok. The Drain pump replaced & pump cover is ok. Reed switch flow meter has been replaced.
Anyone offer any advice please?
I’ve seen this be the drain valve in the side tank, it fails and lets the water run back in. Next time you see there’s water left, check if the tank is empty or not.
