My Neff dishwasher displayed a fault & engineer came out quickly & for a few washes all was well until the fault appeared again. Another engineer came out but said I needed a new motor. A new motor was ordered & fitted & on first use the fault appears again. Not sure it could have been tested properly. I seem to have to wait 2.5 weeks each time for an engineer to come back - there never seems to be an engineer in my area ! Very frustrating especially as I have now waited in 3 times & the problem is still not fixed, so back to hand washing for several more weeks.
