Help with a Neff diswasher

54and56

Hi all,

I've a Neff dishwasher model S44T09N4GB which has stopped working. I'm not sure whether the program which controls the settings has become scrambled somehow or there is a plumbing/component problem which is preventing the machine from filling with water.

The machine was put on last night and ran through a normal program but when we went to empty it this morning nothing had happened and the dishes etc were exactly as they had been put in.

I tried running the program again but after a few minutes opened the door hoping to see water being sprayed everywhere but it was bone dry. It makes a noise like its trying to pump water in but thats as far as it gets.

Here's a video showing the machine starting up as soon as a program is selected which it shouldn't do as it's supposed to not start until the door is closed which is why I think a malfunction with the program may be a contributing issue but my hunch is that its mechanical/plumbing related rather than electronic.

Any thoughts or suggestions as to how I can diagnose the source of the problem?

pull out the machine , make sure its empty and then tilt it either back or forwards as much as possible and then try it again, it should fill then but if the problem reoccurs there is a leak, normally from the circulation pump. have a towel ready for any mop up

Thanks Red Ace,

I didn't have a clue where to start so your suggestion was perfect.

I pulled off the kickboard and eased out the dishwasher as far as the pipes feeding into the back of it would allow which is about 18 inches. There was no water under the machine so no sign of a leak and I didn't want to cause one by pulling the machine out too far and ripping a pipe off its connection.

I wiggled the machine as much as I could which wasn't a lot as it was still half under the kitchen top and ran a quick wash. After a few minutes I opened the door and there was water shooting everywhere so delighted with my handywork I pushed the machine back into place, loaded it up with dishes and stuck on new quick wash only to find out a few minutes later that despite sounding like it was cracking on with a cycle it was bone dry again.

I pulled it back out again and tried starting it but again it remained bone dry and the control system is still acting weird i.e. the motors/pumps stay on trying to inject water (I assume) when I open the door. The machine should automatically cut off when the door opens but it isn't.

I tried rebooting it by pulling the fuse which serves the dishwasher and waiting a coupld of minutes before starting a load again but that doesn't cure either problem i.e. it still continues to run but with no water coming in and it still doesn't cut off when the door is opened mid cycle.

The two issues much somehow be linked, it would be an incredible co-incidence if two distinct unrelated problems occurred at the same time but it's possible I guess.

I'm thinking the decision I have to make is do I call an engineer out to try and fix it which is likely to cost at least €50 if he just comes and says it's banjaxed or do I accept we've had 8 years out of it and just buy a new one which will be the guts of €500

your assumptions about it having different issues are incorrect, unless you follow the advice I gave you it wont fill, the machine has a sensor that is detecting a leak, that water has to be removed from the base of the machine and unless you can do that yourself you will have to get a tech like me to fix it or else replace it before you have a working d/w again
