The pump on My Miele g646plus will not stop running. As soon as I switch the power on, the pump starts running. Flashing red light for inlet flash drain. I've cleaned all filters and the mains hose and non-return valve. Can anyone advise?

water in the base causing the antiflood switch to come on and make the drain pump run 24/7
turn off at mains.lay dishwasher on it's back slowly then allow the water to run out.leave for 10 mins then stand it up and retry.if the same happens again you have a leak or a blockage/draining issue and you need to strip it and find out where
