I have a small AEG Favorit Proclean dishwasher.
On three occasions the code has flashed 30.
The first time it happened, I tilted the machine and water came out of the bottom and all was okay.
The second time it happened this trick did not work and so I undid the outlet hose from underneath the sink and stuck it out the window and tilted it again. This sorted it out and the machine ran fine for a couple of weeks.
Today the machine is playing up again. Midway through the cycle it flashed code 30 again. I turned the machine off and tilted it again, turned it back on and it seems to be going okay now but is there anything I can try before it happens again? Thanks for reading and thanks in advance for hints, tips and advice.
