Hi there I have a very old Bosch slimline dishwasher all anologue it suddenly stoped working yesterday all you can hear it doing is pumping out then stops not even the timer moves.
I head on another post on here about removing left panel as water could be in there or something well I removed the panel there is this yellow kind of plastic sheet under the panel at the bottom as a max and min there is water way past the max but cannot seem to find out how to drain the water any ideas thx George

Water has leaked into the base and activated the anti flood device float switch. You will need to find the source of the leak.

You need to tip the machine back / forward to drain the water away and reset the float switch. You may have a small removeable panel at the front of the machine on the bottom.
