Hoover Wdyns654D Keeps Filling Even On Spin Cycle
Hi folks, I would appreciate some help with solving this problem if possible
When starting any cycle the machine fills with water as normal.
The inlet valve solenoid then pulses open and closed throughout the wash cycle, resulting in an overfill.
Even on the spin cycle the inlet solenoid is pulsing open and closed and is letting water in.
I have checked the pressure tube for leaks and replaced the pressure switch for a new one.
I can empty the drum of water by putting it on a spin cycle, the pump will eventually empty the drum even though the inlet valve is still pulsing.
I did notice something odd today, when the programme selector was in the off position one of the digital LEDs was flashing, not the complete digit only the top bar of the first digit on the control panel, then several other LEDs flashed in a random pattern only for a brief period, it reminded me of the close encounters film.
Any ideas?
Thanks in advance.

This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.
Hoover Wdyns654D overfilling and taking in water even on spin
- The problem
- Hoover Wdyns654D fills normally at the start, but the inlet valve solenoid then repeatedly pulses during the wash and causes overfilling. The same pulsing and water entry also happens on spin. The pump can eventually empty the drum on spin. The user also observed random flashing of some display LEDs when the selector was set to off.
- Likely cause
- The accepted diagnosis was a low insulation fault, commonly on the pump, causing erratic control behaviour. The reply also noted it could instead be an insulation fault elsewhere, a poor PCB connection, or another related electrical fault, so the exact failed part was not confirmed.
- What fixed it
- No DIY repair was confirmed. The recommended action was to have the machine professionally traced for a low insulation fault using appropriate test equipment and to inspect the relevant components and control connections. Further diagnosis should be carried out by a suitably qualified appliance engineer.
- Checks to try
- Pressure tube checked for leaks
- Pressure switch replaced with a new one
- Connections were wiggled, removed and re-seated
- Pump operation observed: it could eventually empty the drum on spin
- Parts or tools mentioned
- Pressure switch
- Special insulation tester (megger)
Safety: Further diagnosis should be carried out by a suitably qualified appliance engineer.

Low insulation faults on pumps can cause weird faults like this but there could be an insulation fault elsewhere or a dodgy connection in the pcb or something else. It's not necessarily a serious fault but you really need to find an engineer to trace this one

Thanks for the reply Andy, I did give the connections a good wiggle, took them off and re- seated them but to no avail I'm afraid, considering the cost of a Hoover engineer call out is £120, what and how would he go about finding such a fault?
Low insulation faults are diagnosed using a special meter (megger) which puts 500 volts (DC) through the machine and tests to see if any of it leaks to earth and you can test individual parts to see where from. There are engineers costing a lot less than Hoover on my find an engineer page http://www.washerhelp.co.uk/book_washing_machine_repair.php
