I have the Electrolux ESL6211LO. The warning light is the…

Ok as you are getting the single flash from it then this is indeed a filling fault.

As it fills and washes then its possibley the pressure switch at fault here. As ive replaced quite a few of these in the past for failing during the cycle. So as it fills we know the water valve is fine, The wiring is fine and the control board will be.

So usually for this fault we just replace the pressure switch. This is loacted on the right hand side of the dishwasher so you need to remove the top and side panels and then you can access the pressure switch from there.

Ok bit strange for the 3 bleeps and theres no water in there.

Check the wiring to the microswitch and also lift the float up and see if you hear the switch click as you lift it up and down.

As the service manual states for the anti flood error code its either the float stuck, water leaked in base, the microswitch,wiring or the control board at fault here.

So check the micro switch and the wiring to it first and see what you find.

Ok so if the pump is running all the time even if the float switch isnt activated and the switch is fine then its looking like its either the wiring to switch running up the door or the control board itself im afraid.

As to the 4 beeps this is a pressure switch related fault again im afraid.

Yes it could be.

Remove the pressure switch again and refit it and check the wiring plug to it as well.

If all that is fine then its possibley a faulty pressure sensor at fault here.
