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.

the problem is hard water. There is a new product out called The Dishwasher Filtration System. It filters the water going into your dishwasher leaving your dishes spot free with every load. It is very affordable and fits right under the sink. You will be amazed how sparkling your dishes look just after one load. You will love this product. Get it at www.dishwasherfilter.com.

Same thing happened - couldn't do anything - was completely "locked"...tried the breaker reset and it worked immediately. Thank you for sharing the answer!

If you have hard water, glasses can look spotted and cloudy even after cleaning. Sometimes changing the dishwasher detergent can help. The easiest solution to clearing up glasses that start to look cloudy is to add some vinegar to the bottom of the dishwasher before you start a cycle. Simply add 1/4 of white vinegar and it will clear up your glasses very well.
You should see marked improvement after the first time you do this. If they are not crystal clear then simply repeat the process until all of the cloudiness is gone. In fact I recommend to using a little vinegar in each cycle to maintain the clarity of the glass.
Note: you can pre-test this by rubbing some vinegar on an individual glass with a cloth. If you cannot remove the cloudiness by soaking it and rubbing vinegar on it then it is possible that the glass is etched due to harsh or cheap dishwasher detergent and vinegar will not solve the problem.
