Dishwash machine electrolux esf 6121

i think that is engaged via a _(i can't think of the word.. it's a points set that works off an electro-magnet) if that got stuck then it will keep the pump engaged in the drain mode.. otherwise it's an issue with the settings.

I would replace the switch assembly.

The anti-flood system has been triggered means that water remains in base because leakage or overflow. In this case, in order to prevent flooding, drain pump running continuously.
Remedy: you should first remove the water from the bottom of the dishwasher and determine leakage.
If you work around the dishwasher, you always take care that appliance must be disconnected from the power supply.

this fault can be the heater which has an electrical earth fault. You need an insulation tester to test it. The heater is accessed from the right hand side and is a cartridge type insert in the flow to the top spray water supply.

Mine did the same thing. Turned out it was leaning back a bit, so I leveled it and now it seems to be working fine.
