Hoover Vhd8142-80 Not Starting
Hi,
I have a hoover VHD8142-80, it was stoping towards the end of the wash with flashing led lights indicating heater element. This was not replaced and ignored about a year now. The machine now does not run after triggering off electric circuit breaker, once breaker turned on the machine was still on the cycle with nothing happening except when dial set to off door would open eventually.
It was left to finish the cycle which took approx 24 hrs, but now when attempting to start, it sets a wash cycle with door locking but the door security light keeps flashing and the wash never begins, no drain pump sound, no motor spinning, just nothing apart form door locking.
I decided to change the heater element but still the same symptoms.
The drain filter was clogged with large pieces of limescale and 1p coin, drained and removed. However, still nothing.
Drain Pump?
Motor?
PCB ?
Can anyone give me any advice?
When the wash is placed on hold, continuous flashing of the "timer saver", "Sensitive Care", "Stain Blaster" and the time for cycle. The security door light turns off during pause but door remains locked, normal I guess.
Thank you

Hoover VHD8142-80 will lock door but not start after electrical trip
- The problem
- Hoover VHD8142-80 stopped near the end of washes previously with LED indications said to point to the heater. After a single circuit-breaker trip, the machine later completed the cycle very slowly, then would only set a programme and lock the door. The door/security light flashed and the wash never began. There was no normal drain or motor action at start. The heater element was replaced and the drain filter was cleared of limescale and a 1p coin, but the fault remained.
- Likely cause
- Most strongly supported diagnosis was an electrical insulation fault or short-to-earth on a component such as the motor or heater, with possible damage to the PCB after the trip. A PCB fault was considered possible, but not confirmed.
- What fixed it
- Accepted advice was that the fault needed tracing with an insulation test meter, as a standard volt meter was not sufficient to diagnose a short-to-earth fault. If no obvious damage could be seen, the next sensible step was professional diagnosis, including inspection/testing of components and the PCB. Exact repair was not confirmed in the discussion.
- Checks to try
- Heater element replaced
- Drain filter cleaned; large limescale pieces and a 1p coin removed
- Motor carbon conductors checked and reported as over 5mm
- Drain pump observed to twitch/fidget when the machine starts
- Visible wiring inspected with no obvious bare wires seen
- Parts or tools mentioned
- Heater element
- Drain filter
- Motor carbon conductors
- PCB control board
- Voltmeter tester
- Insulation test meter
Safety: Further diagnosis should be carried out by a suitably qualified appliance engineer.

The motor and heater are the two most common causes of tripping the electrics. If the motor goes down to earth it can damage the pcb. To trace this fault you need an insulation test meter to see if anything is shorting to earth. If you don't have one (and it's a specialist meter) you can't trace this fault unless you can see something very obvious to account for why it tripped out the electrics.

Hi,
No one has replied unfortunately.
I happen to check the motor, which still had over 5mm of the carbon conductors and the drain pump is fidgeting when the machine starts. So I'm disregarding both the motor and drain pump as the issues and can only think its the PCB control board.
Could anyone give me an idea if this would be the most sensible conclusion?
Thanks and regards
I have this article on washing machine tripping electrics which explains it better

Hi WH_WGH,
Thanks for you reply, I do have a volt meter tester, which I used to check if there was current coming towards the motor and drain pump. Not that I know what I'm doing with it but appears to be current going to these organs. However, the breaker tripping episode was only the once and it hasn't happened again. We have had trips in the past but once in a blue moon for different parts of the house. However, the washing machine has never mulfunctioned before.
I was wondering if it was more due to a power surge rather than the machine causing the fault? Maybe some rats nibbling on some wiring.
I inspected what wiring I could see and they all appear to have insulation on then, no naked wiring.
Seen as there hasn't been another trip, what would be your suggestion on the next step?
Thanks
If it only tripped out of the blue then I agree it was possibly one of those things and no part is down to earth. It's possible for intermittent leaks or wires rubbed bare in the harness (out of sight) to cause intermittent tripping of the electrics but I'd only worry about those if it was doing it regularly. It could be a power surge, or something that shorted out a circuit on the main pcb.
It's even possible for a part to go down to earth and blow the circuit which supplies power to it so that when the power is restored, even though the part is still down to earth it no longer trips the electrics because it's no longer being powered up. Apart from inspecting the pcb there's nothing else to check. An engineer would get his 500v DC insulation meter and check the components first.
