My neff 5543 fitted dishwasher has stuck on drain. The pump will not stop running, even if I open the door, or re-set the programme. The only way to stop the pump is to turn the whole thing off.
Any ideas what's wrong? Is it easy to fix?
Thanks in advance

Re: Dishwasher stuck on "drain"
Not easy to fix - it has a leak. the tray at the base is full of water which ooperates a float which switches drain pump on. remove front panel at bottom front and mop out water or tilt backwards 45deg and water will run out. leak is usually main pump

That is the classic behaviour of a flood sensor being wet. You said 'anti flood float'. I know them as a small sensor in a tray under the machine and above the floor in a plastic pan. If it is that where your float is, then you need a service call to diagnose. It is likely to be a circuit board issue and they are expensive so need proper eyes-on trained diagnosis.

If the appliance stops during dishwashing or does not start for no obvious reason, first run the Abort
programme function (Reset).
Terminating the programme (Reset)
1. Open the door.
2. Press START button 9 for approx. 3 sec. until all displays go out.
3. Close the door.
The remaining programme sequence for draining the residual water takes approx. 1 minute.

If you take the kick plate off from below the door youshould be able to access the base to remove any excess water.Behind your kick board is a plate below the door. Remove theplate. With the power off push a rag into the base plate to soak up the water. Failing that pull out the dishwasher onto the floor and tilt the machine backto allow the water to run outSwitch the water and power back on and restart the programto test.If the appliance is less than 2 years old Neff/Bosch Groupguarantees it
This depends what you mean by "runs". If the dishwasher continues with a wash cycle - i.e. circulating water - with the door open, the simple answer is that you have a defective door microswitch.
However, I suspect what you perceive to be the dishwasher running, is actually the drain pump running continuously. This happens when the anti-flood protection system has been activated and continues even when the door is opened. The simplest way to check is to open the door (while it's "running") and pour some water into the tub. If the water drains away immediately, this shows the drain pump is running and the anti-flood protection has been activated.
This may be due to water having leaked into the base of the dishwasher, but it could be as simple as a stuck or defective float-switch.
Please try the simple test above then post back for further assistance. If you're planning to investigate or repair this yourself, you're going to need a Torx T20 screwdriver and a multi-meter would be useful as well.
The water which has activated the antiflood device is actually underneath the appliance it is held in the sump tray and this has to be drained before the A.F.D.will cancel.You will have to remove the dishwasher to get at the underneath but when you have got rid of the water you will still have to trace what caused it.The seal on the circulation pump could be a suspect or a pin hole in the drain hose.
This is caused by a water leak into the base pan,it will trigger the anti flood and the machine will continously drain out even with the door open,you need to establish what is leaking,if you leave the appliance standing for a few days it will start again as the water will evaporate however if the fault returns you will definetly have aleak on the appliance which will require further investigation.
Our Neff Dishwasher S5456X0 the pump was running all the time and the solution 1 worked. We removed the front panel under the door and the the flood camber was full of water. Drained it out with a sponge and the dishwasher is fine. Thanks
First try disconnecting the unit, completely from any power, for an hour or more, look in any control doors or access points for a small battery mounted to a board or in a holder, if you find one, take it out also, noting the positive and negative orientation.
If that doesn't do it, there are reset buttons under the tops or lids of some NEFF models, if there is an obvious lid after trying the no power trick, take off the top and look for a stand alone reset button.
This is a on going problem with asko and they keep jerking everyone around with this defect. I had a repair person come over and used a turkey baster with a 7" rubber hose attached to the end of the baster. He took off the kick plate and inserted the hose end in the overflow tray and pull about of 12 onces of water from the tray. He is a asko repair facility and says it is a comon problem and has made the repair solution on his own as it is easier then taking the hole dishwaser out and tip it on the side just to drain the water. This has been on going for 3 years and each time i called asko it was like i was the only person having such a problem. I now do this every 3 months and the problem is on going. What a piece of junk. Purchased at Marcellas appliances in Schenectady,NY. They also know how to avoid the problem in fact there repair person left out most of the screws so the next time it would take less time to drain the water. DDDDDont buy ASKO. Michael Foote
Hi there ....this condition is ususally caused by a water leak into the sump of the dishwasher which activates a safety switch to run the drain pump..preventing the appliance from being used....Remedy...tip the dishwasher back in the head allowing excess water to exit from the sump...then with the door open check that the air vent lock ring is secure, thet the salt unit retaining ring is secure..and finally that the filter unit to base screws are secure...this done re-start and you should b fine
