Put on a programme and the dishwasher a Smeg DWF1-2 stops after around three minutes with the Bio light giving a flash though not using the Bio. After restarting and switching of the bio light the same thing can happen several times. The machine is erratic and sometimes continues to wash but stops again. I open the door and the plates are quite hot. I get no error code. I have looked at the bottom of the machine and there is some water remaining in where the filter resides which I have removed and had a look is this normal. The only cycle that seems to work without a problem is the P1 soak.
