Checked this error on here and online…… it all indicates a fault with the anti-flood BUT there is No water in the base whatsoever, the float is fine and the switch is good…. There’s no sounds like the pump, it just lets you select a setting the the end light flashes 3 times and bleeps?
Have cleaned out the pressure switch and the customer ran the dishwasher for a few days without any trouble….. I ordered a replacement just to be sure.
