This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.
Hisense WFHV7012 stops near end of cycle and then appears dead
- The problem
- A Hisense washing machine, model WFHV7012, was reported to stop with about 10 minutes left in the programme. The display went off, and afterwards switching it on produced only a relay clicking on and off with no display.
- Likely cause
- The accepted reply said this most strongly suggests a power supply issue. The first suspected cause was the wall socket or its wiring connection. Other possible causes mentioned were a dry joint, a loose connection, a fault on the PCB or control panel, the on/off switch, or the door lock. The exact failed part was not confirmed.
- What fixed it
- Recommended action was to first rule out the wall socket by trying the appliance from a different socket. No confirmed repair was documented in the discussion. If the fault persists, further diagnosis should be carried out by a suitably qualified appliance engineer.
- Checks to try
- Observed machine stopping with 10 minutes remaining
- Display went off completely
- Machine then only produced a relay on/off sound
- No visible blown component seen on the board
- Try a different wall socket to rule out supply issue
Safety: Do not bypass safety devices. Further diagnosis should be carried out by a suitably qualified appliance engineer.

Hi. Sounds like a power issue. First thing to discount is the wall socket. Try a totally different wall socket. I've had appliances just die halfway through running caused by loose connection in wiring in wall socket. Other than that it could be tricky to sort out. Could be a dry joint, loose connection somewhere or a fault in the PCB or control panel. Could even be a problem on the on off switch or door lock.
