Question about Zanussi 24 in. DE6850 Free-standing Dishwasher
When a program is started the machine pump runs and after a few seconds the end light flashes three times. The user manual states that this is for flood protection. Is there a common part failure with these dishwashers or is it most likely to be a blocked drain hose.
Had the same problem on a Miele mashing. In my case trying to clear a drain blockage in a kitchen sink had probably forced water back into the washing machine and caused an internal leakage. Rather than remove the whole machine and tip it over, I opened the small panel at the front bottom (behind the skirting panel) (needs 'special' screwdriver for the 2 screws) and removed the water that was lying on the base of the machine. Not much (less than 5mm) but enough to lift the white polystyrene float (a round disc about 10cm diameter) which was activating the micro-switch and causing the F70 message.

The flood protection unit is placed at the front of the bottom front panel of the washer. The front panel just clips out revealing the inner gubins. If nasty liquid comes out when you tip the unit over this may be because over time & not quite emptying those cups of tea etc before putting the cups into the washer, this old liquid flows along the bottom door seal & into the bottom drip tray via the door hinges. Scunge builds over time & it does not take a great deal of liquid to trip the flood protection. Solution? Tip over the unit, allow the scunge to come out, disinfect as best you can (including hands after this operation, its life in there Jim but not as we know it!) & test out of situ with something like a Finish dishwasher cleaner. Saved me a call out & cost me the cleaner only. Result.

Flood protection is generally activated when a leak occurs.Leaking liquid ( water + ....) in a bassin at the lowest point in the dishwashers. In the bassin is also a floater, which goes up with incoming liquid , and at a certain level, by means of a cantilever it will activate a micro-switch, and holding the dishwasher on alert. Unplug the diswasher, and tilt it over up to 60 degrees. If liquid gets on the floor, there is a leak somewhere, most often between pump and spraying arms. ( Maybe these where not cleaned and block the pump, so pressure can get high and liquid leaves at wrong place). Check if spraying arms are not blocked, and then try if the dishwasher starts again. If after a while the flood protection start again, call a repair-service. If no liquid gets on the floor, probably the dishwasher was moved recently, it is possible that the bassin itself has been pushed up by a foreign body to the diswasher. Again , tilt the diswasher and look under the dishwasher.

Miele provider the only solution to this situation. They installed a brand new unit because we were still under warranty. They took the old machine presumably to try to find out the cause of a the failed water inlet valve on the reservoir tank. Before they took the machine they tried to relieve pressure on this valve by placing a larger (less pressure) blue restricter when they replaced the tank for the second time, but even with two new parts it did not make it through the first wash cycle before flashing the infamous F70 code.

MY DISHWASHER STARTS BUT THE WATER DOES NOT COME THROUGH AT ALL

You should be aware that the overfill overflow, the short pillar in the machine with holes in it leads directly to the bottom tray and it will partially immerse the pump motor and cause it to fail. There is nowhere for the water to escape, apart from tipping the machine over and draining the water on floor. It appears that water could seep through through the overflow during normal operation.
If water is getting into the tray through the overflow you can prevent this by turning the machine on its side taking off the bottom tray and then connecting the rubber tube that comes out of the overflow back to the other outlet from the overflow forming a closed loop. All that will happen now is that if the machine does over fill (unlikely - this must be a failure) then the water will seep from the door seals. It will not sit in the bottom tray and cause the main motor to fail.
I have heard that the newer models do not have the overflow holes in the pillar - draw your own conclusions.
Please note that I am just an owner, tired of replacing pump motors and wondering how to extend the useful(?) life of a machine that was bought new just a couple of years ago. I would not recommend the D63.

I have had the KUDD01DPPA drawer dishwasher since 12/30/05. The "Flood Switch" has been activated 8 TIMES. Our dishwasher is not freestanding - it is under the counter; therefore it does not move. Tilting it would be impossible. We've had service on it twice. There answer to us was to "shut off the breaker for several days and see it that works." We need another dishwasher!

I had the flood switch activate. removed the drawers and found that water was leaking at the back of the top drawer. They use a re-enforced white plastic cable guide and support on the hoses (in water, drain out, elect connect)to each drawer. The one to the top drawer had broken in half. When the drawer was shut part of the cable guide got caught over the top of the drawer. This prevented the seal from closing properly and allowed water to leak out. Used wide electrical tape to hold it together and dried up the water. Worked ok until I could replace the cable guide

Simply it could be the door seal has deteriorated, especially around the bottom, letting samll ammounts of water to escape below where the floater switch is helded, causing a short.

I have the same problem if you take off the tray below the front door and set a small blow heater in there it will dry the out the anti flood switch. It usally takes about 25 mins for the machine to start working again.

This is for the right model, but is the UK version, all should be the same but power supply details might differ if you are in US etc. http://www.serviceforce.co.uk/pdfs/U23297.pdf Hope this helps :)

I think I had a similar problem to this. It seems like it was starting a cycle but then it just stalled and made a buzzing noise and it did not drain properly. I opened the bottom of the dishwasher where the draining pump was located. take off the plastic cover and I found bits of broken plates were jamming the fins on the pump... Try this and see how it goes.. Hope it was of some asistance.
