SOURCE: 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

chucked it !!

We had this problem with our machine.
There turned out to be a few things that caused it:

- Firstly, the float assembly (an orange looking float in a little chamber, visible if you take off the left-hand panel of the machine) was clogged - we cleaned this and it seemed to help.
- The heat exchanger matrix was full of debris - we tried to clean this but ended up damaging it and bought a new one.

.. these two things seemed to improve the cleaning and the machine worked for a while.

The real problem though (which caused it to pump out continuously) turned out to be a failed seal on the circulation pump.

If you look on page 4 of the following link:

https://www.neff-eshop.com/eshop/neff/gb/prodp.htm?eShopType=S&prod=S5456X3GB%2f22

.. you will see a diagram of the bottom of the machine - the part that failed was 171598, which you can see on the bottom middle-to-right hand side of the picture..
The rubber had perished very badly, and it was causing water to leak into the bottom of the machine, which triggers 'flood mode' whereby it pumps continuously and doesn't actually wash the dishes.

The part costs about £5 - fitting it is not straightforward though, as you need to strip the machine down which is a pretty involved job.
If you think you're up to it, the steps I followed were:

- Remove both side panels
- On the left hand side, remove heat exchanger matrix and float assembly
- Remove kick-panel under the front door
- On the right hand side, remove all wiring from the door to the machine (including an earthing wire which is screwed to the side of the machine) - note that there are two wires which go to push-on connectors which have to be removed separately - all the others go to connector blocks.
- Inside the machine, remove the wire baskets, spray arm and bottom filter.
- Remove the lid from the salt dispenser - and now the tricky part, you need to find something that will allow you to remove the large plastic 'nut' that holds the salt dispenser to the machine.
- Remove the two screws in the bottom of the machine (167241 in the diagram mentioned above)
- Now, shut the door and then disconnect the door spring mechanism from the left and right side of the door.
- Disconnect the string from the door closing mechanism from the springs at the left and right back corners, under the machine.
- Remove the two screws at the back of the machine which connect the top of the machine to the base.
- Remove the two screws at the front of the machine which connect the top of the machine to the base (these are quite low down, near the door hinges).

Now, you should be able to lift the top of the machine off the base, and will have access to the pump etc.


... re-assembly is the reverse of disassembly ;-)

This took me a couple of hours - it might be better to find somebody who will do it for you for fixed cost as it's a pig of a job.


For what it's worth, there seemed to be very few places where the machine could leak - and this looked to be the major one - and there are a few push-fit pipes which are worth checking out too.


Hope this helps somebody.

What your saying is suggesting a water supply issue. The Model number you've given can not be found on the Neff website.

You will need to disconnect power, turn the water supply off (under sink or behind dishwasher), disconnect the water line, put the end of the hose in a bucket or cup, turn water back on slowly and make sure water flows. Turn back off. If water flows -

Then check that there is not a restriction in the water solenoid valve. If you know how to use a multimeter, check the water valve solenoid for continuity.

Plug the unit back in, and initiate a wash cycle, and watch for voltage applied to the water solenoid valve. If you get voltage, you should hear the valve open.
Power the unit off, connect the water line, and repower the unit. Check again if water does or doesnt flow.

Let me know what you find.

SOURCE: my dishwasher is not filling w water

check filter or drain hose it probably have a dirt,try to fill with water manually and turn on pump to dispossess water,if water not go out and pump work then you have dirt in hose or filter,if pump not work then pump is broken.
