DISHWASHER- Model no: DW009

I experienced exactly the same problem with this Model. The handbook says code E4 is an overfill problem and in my case because the filter had become blocked, water had somehow found its way into the base of the washer (where all the electrical stuff is) and activated the anti-flood device. The solution is to simply get the water out of the base. Making sure the unit was switched off at the mains, I removed the wooden kick-board from under the kitchen units and the screws securing the washer to the units. I then lowered the 2 front height adjusting legs so that the washer was slightly tilted down at the front. There are 2 black plastic access covers at the bottom of the unit which can be gently prised out and then use a cloth/sponge, removed all the water that had collected in the base. This cured the problem without the hassle of removing the washer altogether.

i dragged my DW009 out today 17/02/08 took the side panels off, thought i'd take a look!. i had'nt got a clue i might as well be looking at a cows backside, there was no water in the bottom pan, ho hum put the panels back ....now it works fine..no more E4, beeping and draining. my conclusion is it only needed a good hard kick. hope this could be of use to someone else?

my dw009 is showing e2 does anyone know what it means ive tried everything
