Re: miele g180 flashing lights. alarm cancel?
Best to take out dishy, tip up to empty water from base. It will reset & work o.k when float switch is reset.
A solenoid valve needs water pressure to stay closed, if theres no pressure to keep it closed it can leak through, it just needs a little trickle.
Most Mieles have a dual solenoid in series in the intake pipe, if this is leaking through it may have grit or sand in one of the valves & need replacing.
