That’s it really: the machine has been pretty reliable but when I came to empty it after a wash, the drain pump was still running. I switched the rotary switch to off and it still continued running. I’ve switched off at the mains, had a look at the drain pump access, and there were a few bits in there but nothing much. Leaving the mains on I can see it spinning happily. Also checked the drain hose at the sink junction – that’s clear.
Now what? Could this be a controller fault? Any suggestions as to how to troubleshoot? Thanks 🙂
OK – more information: had a peek inside and I can see water – and the reason is one of the hose junctions on the detergent box has cracked open. So it’s leaking water when the fabric softener cycle runs. I can fix that, but I’m assuming there’s some kind of float switch that’s triggering the drain pump – where is that and how do I reset it?
OK- I’ve dried it out and fixed the leaky pipe. Let’s see if it works…
No idea of the actual model number! So basically you have/had a leak from the soap box nozzle`s black rubber hose – so one of the valve to dispenser hoses -plus the drain pump is constantly on. Normally it is a duff triac on the printed circuit board gone wrong BUT it can be a melted inlet valve coil ( which may or may not be fairly obvious so have a good look ) so turn power off remove lid, take a note which wires go where on the valve. If a double valve you remove the 2 wires off one solenoid, isolate them with tape as necessary switch machine back on see what happens with the pump, if no joy still do the same with other solenoid and if still no joy there turn power off again, remove back panel, and disconnect the two heater wires and isolate those and then retry. If still no joy most likely the pcb which would not surprise me as Hoover pcb`s are not the greatest. If you find any blown tracks or a physically looking blown up electronic component something PROBABLY (?) caused it ( the leaking water onto something ). If the machine has blown-up components and is still under the Hoover 10 year parts warranty call them out just in case it goes pop again – the parts cost them very little but a blown board is expensive for you and will be not covered if you bought and fitted it…….TAKE NOTE!! OR, more rarely can be a duff water pressure switch stuck on emergency pump out. Without the actual model number difficult to know..Check the pcb last.

Thanks so much for this comprehensive answer – really appreciate it. It turns out that a plastic nozzle with a black water inlet hose had cracked and was spraying water around the machine. After locating that, making running repairs with careful use of epoxy putty, and then drying the inside of the washer out with a fan heater, then putting it back together, the machine started working normally again. So I have to assume it was flood switch – although I couldn’t see but there must be one.. (Same thing happens with dishwashers – machine goes into manic drain mode if it thinks it’s flooded.)
I’ve never known hoover washer or even there dishwashers to have float switches the water valve and drain pump where wired on the same wiring to pcb on some machines so if pump is dis connected no water would come in
“more rarely can be a duff water pressure switch stuck on emergency pump out” This is where the pressure switch clicks once but there is a high pressure switch, a stage 2, built in to the same pressure switch that if triggered turn off the valve and turns on the pump. So just maybe the pressure switch is nuked
