I’ve searched the forums without success to try to discover what the E9 error code my Diplomat ADP 8234 dishwasher is displaying means! Unfortunately the instruction manual doesn’t list this code 🙁
The dishwasher will start the programme, but stop after a minute or so – before any water has got to the dishes.
Basically, it’s the flood protection system being activated, repeatedly. This means that the water level control system is not being activated. Level switch may not be working (unusual), or there is a blockage in the pipework somehere (common).
