Why is my Neff dishwasher working with door open but no lights are on? Seems to be stuck taking on and draining water.

Taken From the Manual (https://media3.neff-international.com/Documents/9000816278_I.pdf)
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.

Drain hose clogs commonly occurwhere the hose is attached to the main household drain line, or where the hoseconnects with the garbage disposer.

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

Hello,
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.

Hope this helps.

You need to operate the door release handle at the same time as applying pressure to the latch you can see just inside the door (imagine which way it would move if the thing was working as designed), the tech has possibly simulated a door closed position for testing purposes.

yes take it apart under sink where it drains could be gunk in there

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.


If all that fails, write me back

I have the same problem with my newly installed Miele integrated dishwasher. The door does not stay open when you are trying to load dishes. I heard that there is an adjustable internal mechanism to adjust the tension on the door. But, I am still working on solving my problem.

if this machine uses an electrical-mechanical timer with cam switches, the try oiling the shaft bushings both for the timer motor and cams-the timer may be getting stuck because of dry or corroded bushings

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

I have just encountered the same problem on my S5433 XO GB/13. Did you manage to get a solution.
