Re: Miele G646SC plus filling/drain problem
I have a Miele G692 SCI Plus which had a similar problem a while ago.
The inlet/drain light also comes on when there is water in the base pan. There is a float switch that also triggers this and over time if water has collected in the base pan the float switch can stick. Pull out the dishwasher and tilt it towards to back. If there is any water in the base pan it will come out. To be thorough, put the machine on it’s back and remove the base pan (4 screws by the feet), the float switch is a circular plastic casing with a polystyrene float in it. It comes apart for servicing, the float can jam if there is any rubbish in the water.
