Neff dishwasher is so old, no on-line parts supplier can even identify it!

some of the old ones use this

you could post a pic of the valve but may have to host it somewhere else and ost a public link

Thanks Dave and Don…

Yeah, it’s a shame that even the likes of Neff seems to have sold out, by overwriting their database, similarly to Bosch’s new MO, which is to sell cheap (mediocre) stuff using their old good name.

Anyway; thanks for the link and image upload suggestion. The linked part looks similar to mine, but a little inverted. Is this a reducing pressure valve? My unit seems to be able to ignore when the value is open sometimes, as though another valve in-series is still closed/off.

Thanks again!

Update:
I’ll take a picture later and upload to Dropbox.

electrofix wrote:the valve after the inlet valve is an overflow sensor. it uses air pressure from the machine to stop it filling if its over filled

you need to check you need a valve before you order as it could be down to a blockage in the machine.

Dave

Thanks Dave, I’ll do that.

Currently, I can’t imagine that there’s a blockage as it will often fill when appropriate and without intervention, and sometimes not fill when appropriate – when there is no water in the machine. If the machine seems to be “stuck” in the cycle, tapping on the valve makes the water flow in. What makes me ask about the reducing-pressure aspect is that water can be flowing in happily, and then stop after what seems to be an appropriate time, and yet the valve is still energised. From what you’ve said, I think this seems consistent in principle with it being a “working” overflow sensor dictating to the valve.

Thanks again Dave.

then try the machine
if water flows out of the thin tube ( wont be gushing as its not under pressure) then you know the overflow mech is causing the problem

if the machine still has the fault you have prob got a faulty valve

Dave

Thanks, I’ll do that too. In the mean time, here are two links to two shots of the valve from different angles – as it’s not out of the machine yet:

As I hope you can see, water comes in from the right, the electrical part is on top, the overflow sensor is beneath and the water-out is on the left. I’m not sure what size fittings these are, but if it is indeed the valve assembly, it would be good to have something that is anotomically correct in as many ways as possible – for ease of fitment.

Cheers!

When Hotpoint decided to go back into selling dishwashers they sent one engineer from each district to Peterborough for a five day course on just this 4 model range. I was the designated dishwasher engineer for all of Manchester North. It was over 6 months before I got my first call out, couldn’t remember how to switch the drained thing on.:)

Not sure but think I might have copies of original manuals, will check later.

🙂

Sorry if I sound thick iadom, but this isn’t a Hotpoint badged washer of course. Who is/was BHS?

Update:
Iadom, I’d love a manual if you might have one. Mine’s turned to coal!

Thanks Dave and iadom beat me to a comment about the price. For me, my shoestring just wouldn’t reach that cost.

I guess that if push comes to shove, I could get one with the same connections and buy a shoehorn. I chuckled when iadom said that they were intermittent. Do you think the designers grandson now occupies the position?
