Hoover HD97E dishwasher. 32000009. 0225.
E1 fault.
The fault code guide says time out on fill. The hose was kinked and the valve was silted up; so I cleaned the valve filter and fitted new inlet hose. The water filled quicker, but….
1) The water level was just below the tub rim; (looked overfull) and
2) Five minutes into the cycle and washing normally, the E1 flashes up again and the machine beeps continuously. 👿 The machine has enough water in it to wash, if not a little too much.
I must also mention that it is on a hot supply. There is no room for a ‘Y’ piece amongst the plumbing under the sink so connecting to cold is impossible without cutting the pipes about. 🙁 But it has worked fine like this for 2 years and the problem has only just started.Any ideas?
Thanks,
Steve.
Re: Hoover HD97E dishwasher E1 fault.
It’s got to be water level related. Pressure chamber is a take-off on the front of the sump – sludged? There’s no flow meter on this one to worry about, so slugde, water in the hose and p/sw or p/sw itself I suppose – ain’t much else.

Re: Hoover HD97E dishwasher E1 fault.
Before I put an axe through this thing…… :bang: :angry4:
I’ve taken the sump off and thoroughly cleaned it out – not much sludge present. Refitted it and after sorting numerous leaks from all the hoses, I’m still getting E1 fault. The machine was set to the 29 minute rinse / hold cycle to test fill and empty.
So….I tested the presssure switch contacts empty and full – switching perfectly. 😕 I connected a meter to the valve terminals and ran the machine from empty. Power at the valve OK; fills and the pressure switch clicks off. Power still at the valve…… 😕 😕 Stopped the machine and circuit tested the pressure switch again – working fine. Reconnected and switched machine back on. Power at the valve until 25 minutes and then E1 fault. Machine then auto drains a bit then switches power to the valve back on. But this time it is hydraulically locked off by the overfill. :hmm:
So the pressure switch and the overfill system is working, but still E1 faulting. The only thing I can think of is PCB – anyone have any thoughts on this? Anyone had this fault before?Thanks,
Steve.
