Neff dishwasher won't stop draining

6 posts

I have a neff dishwasher which is just over a year old (hence out of warranty sadly!). Last night it seemed to be a bit blocked after finishing the wash - there was excess water on the bottom of it, so I put it on a rinse, with it empty to see if that would sort out the problem.

The dishwasher beeped to signify the end of the programme, but when I opened it, it was still trying to drain. I can't now get it to stop draining, even though there is no water to drain! I have tried reseting it, but that has made no difference.

Any help gratefully appreciated.

Hi there. I am a Neff/Bosch trained enginner. I can tell you exactly the problem.
Your outlet pump or pipe have got blocked (very common) and water has overflowed into the base.
This has activated a float switch to tell machine to pump out all time.
You need to remove the plinth of appliance and remove with sponge or syringe the water and clear outlet blockage and hey presto all will be fine. Neff will charge you £59.50 for the privlege!
I am now independant and charge £40.00 but you can do this easily.

Thanks ever so much Paul

Having rung Neff it appears the machine is still under warranty, so I will let them do this, this time as it won't cost me anything!

I will print off your reply though, in case it happens again once it is out of warranty.

Thank you so much.

Dear Jo

Be careful! Anything caught in outlet pump is considered a foreign object and we were always advised to insist on payment from customer.
I would recommend attempting this easy job yourself, or at least removing the obstruction from your pump/plumbing as you may well get charged for this.
Most engineers I knew were very reasonable but if there is clearly an obstruction you may well get asked to pay.
Don't assume just because it is under warranty there will be no charge.
Do some checks first. Best of luck!
Hope this helps regards Paul

Hi Paul

We tried to do this job but got very confused. When you say remove the plinth, we thought this was the front panel at the bottom, but there appears to be a whole lot of electrical wires there,which we don't want to disturb! Is the plinth somewhere else? We have taken off the spout type thing at the bottom and removed the metal plate. There is no blockage there and the water drains very quickly if you put some in the bottom, so I wonder if we might have a different problem.

Thanks so much.

Hi there

Sounds like the machine is draining OK now, but if the pump is still running constantly you will need to remove the water from the base. You were in the right area, you need to disconnect the cable holder from the metal plinth panel and take off this panel to reveal the base compartment, where you can remove the excess water, and then the pump will stop running and the machine will now work normally.
It sounds scarey but is a really simple job.
Hope this helps.

Hi Paul.
Came across this thread whilst trying to find out the source of the problem with my Neff. Seems like exactly the problem I have. I've opened the plinth as you said and removed the outlet pipe. All is clear but the pump keeps going. Jo refers to a metal plate?

Many thanks

Hi Tom

Hopefully you will be able to resolve this yourself, but just to let you know our machine did actually have a leak in the bottom which we had to get an engineer to fix.

I called an engineer once we couldn't find a blockage and on the day he was due to come, I switched the machine on to find it had stopped draining! The engineer arrived even though I had cancelled the callout and insisted on having a look as he was here - thats when he found the leak.

The machine was about 18 months old and I thought not under warranty as I hadn't registered it within the required 6 weeks, but Neff said it was still under warranty, so we had nothing to pay.

Good luck with your dishwasher. You don't half miss them when they go wrong!!

Paul,



Picked up this thread as I have a similar problem.



The base of my neff dishwasher fills with water, the float switch operates and the pump operates but the water stays in the base - should this water be pumped out and, if so, from where !!



Also I may have a leak from the machine into the base - any ideas where it is likely to come form ??



Thanks

Hi,

I have just been through the same issue. No apparent reason but continuous running of the outlet pump. I tried resetting the dishwasher as per instruction manual but to no avail.



Removed plinth as per forum suggestions but found no water in base so no draining required. This suggests that machine control system may have got stuck in some sort of loop or that swtich was rading flooding in spite of there not being any.



It's now working again after a couple of wasted hours on a Saturday night!
