Diplomat ADP8332 – F4 Fault

Re: Diplomat ADP8332 – F4 Fault

Very interesting – is the pump easy to replace or is it an engineer job?

Thats the million dollar question isn’t it 😀 as we have no idea of your abilities 😕
To fit new pump you may need some hose clips as they are usually “one-shot”, rather than you get half way through to find you can’t complete 😥
Appliance on its back, base off and of course unplug prior to working on it 😉 Not a bad job TBH.

Within a few minutes of me describing the symptoms and he observing them he diagnosed a split hose on the main wash pump. He knew this without even inspecting the machine because every single person that had this machine had experienced the same problem!. Sure enough when he got the pump out there was a split about 2 ” long around the rubber hose (explains why water was going where it shouldn’t!).

Furthermore, he claims it’s a “known” design fault as the hose is not manufactured to a high enough spec and can’t handle the load put on it. He claimed that Whirlpool are fully aware of this problem but are chossing not to do anything about their manufacturing process!

He reckoned the part would be around £150 ( the hose cannot just be detached and replaced because it is an integral part of the pump) but recommended I complain direct to Whirlpool on the grounds of “not fit for purpose”.

I will let you know how I get on.

I contacting the Customer Service Dept at MFI and they wanted to send an engineer round at a cost of £90. If the engineer agreed it was a “manufacturing” fault my £90 would be re-imbursed and the machine repaired free of charge. I told them to send the engineer round but not expect payment, they refused to help any further and said there’s nothing else they can do and told me to take whatever further action I wanted! – Looks like Trading Standards then

There must be a way of protecting people against this sort of thing or at least warning them. If nobody ever buys one of these things ever again then Whirlpool might take some notice.

Have a looko at this site, which may help:
Bird’s Miscellaneous

It has information on fixing an oversensitive pressure sensor, which will cause a seemingly unnecessary F4 fault.

Mod edit to get link working. Penguin45.

Good piccies – thanks.

Readers should be advised that the F4 problem is plastered all over the Dishwasher Forum and the solution is often to replace the Water Indicator unit. This is because the light-action microswitch attached to the unit often loses its spring.

Replacement is HERE if required.

I have been struggling with the same dishwasher to the point where I replaced the water pump today, but then the same F4 message kept coming up. rather frustrating. I removed and cleaned the water sensor , it is running as we speak and hopefully that is it fixed. pictures in above link were invaluable

Re: Diplomat ADP8332 – F4 Fault

I have one of these “lovely” machines, rather than start a new thread I will bung my story in here.

Originally the machine tripped the electrics in the house, found water in the sump caused by known split hose problem. Removed pump and replaced hose with a nice bit of Audi radiator hose, perfect fit 😆 Reassembled machine thought I had dried everything out but water ingress in the water drain level indicator caused it to burn out and give F4 code.

Replaced drain level indicator (purchased from this site!) and now have the dreaded F4 code at the end of a wash cycle. Now it appears to be stuck in the F4 error cycle. The water drains out as it should but the pump stays on until the F4 code comes up. Holding down the start button clears F4 and the 4 flashes and makes the unit drain and then it goes straight in to F4 again.

Any ideas or just thrown the thing in the bin? 😆

Re: Diplomat ADP8332 – F4 Fault

drain level indicator do u mean the pressure switch?
only 4 things will cause a f4 fault
1st pump aka not draining
2nd pressure switch faulty or weak spring inside it or all gunged up, normally can see white on the black pressure sw in sump if its dirty
3rd module faulty
4th if motor pipe is leaking when on can pressure water over other componets to give fake random faults

I have just used this little guide to fix my F4 problem. In my case it was a Bauknecht GSI 4875 giving me grief.

I’d like to add that I had to apply considerable force from within the “sump” to force the water sensor (i.e. diaphragm switch unit) out. Rotating the sensor was just not enough — I guess it was a really tight fit.

After that, I had to dismantle the sensor unit to get all the “gunk” out. There was a genuine carpet of white goo covering the rubber diaphragm, that I couldn’t get out w/o taking the lot apart. But, no biggie: getting the thing out of the machine though the front bottom inspection cover was the hard bit anyway.

Still…. 100{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} success — w00t!
I’m very happy that my machine is working again, because it may well be 10 years old but it’s good and very quiet.
