NEFF leaking. S44E43SOGB

[rsjon]

My NEFF 6 year old dishwasher is leaking from the door bottom right hand side (as you look at it).
I have replaced the lower door seal with no improvement.
I now suspect the water level sensor is not turning off the water when it should and the machine is simply overflowing.
Can anybody tell me what this sensor looks like, where it is located and best way to test it?
Last time I looked at one of these sensors (years ago) it was on a washing machine and worked on air pressure! 😆
Many thanks,
Jon.

The correct water level is based on a timed fill between the Impellor jug and the main control board. As a rule the Impellor jug is the guilty party and would need replacing I would think.

Thank you very much for your quick reply.
Where and what is the Impellor Jug?
Does it provide a signal to the PCB to calculate the volume of water?

Sorry, bit lazy there, just looked up the Impellor Jug and I know where that is on the machine. I guess that counts the water flow and lets the PCB know.
Do they seize up or just go inactive?

They wear, the spindle is only flimsy plastic with a fairly short but hard working life….cheap to replace though fortunately. 😀

Thanks for that great info.
I’ll get one ordered and give it a try!

The faults keep coming….
Now it fills and then drains for a few seconds and then fills….and so on.
Level in the machine is about the salt container lid so I think that’s right.
Problem is I have no repair manual so I am groping in the dark.
Can anybody help. please?

Re: NEFF leaking. S44E43SOGB

Did you order and fit the Impellor Jug then?

[rsjon]

Re: NEFF leaking. S44E43SOGB

Yes, fitted and now more probs.
I wonder if the new impellor jug is faulty?

No, put you could easily fit it the wrong way round. There is an arrow stamped on the side indicating the direction of flow so best check that and then get back to us!

Re: NEFF leaking. S44E43SOGB

Will do! I just put in on the same way as the old one!
Be back in a mo when I have checked.

Re: NEFF leaking. S44E43SOGB

OK, pulled out new IJ and it is exactly the same as the old one and the arrow is pointing in the same direction.
However, when removing the IJ the connector to the tiny PCB may not have been fully pushed home onto the edge connector on the PCB. I have now fully clicked it on and set the machine off on a quick cycle with no dishes etc in it.
So far it seems to be working normally. The water filled up until it was just lapping the salt container lid and then went into its’ cycle. Still running now with no leaks so far; will let you know whether this is a success later today.
Thanks,
Jon. 🙂
