Hi there,
I've had my washing machine over 2 years without any problems until I came back from a couple days away. The washing machine appeared to be powered on (not on a cycle) while in the off position. The display flashes no errors but where it should flash digits and letters looks just like gibberish. As soon as I tried to unplug it the whole house tripped out (doesn't seem to be a problem now). It looked as though it might have had a power surge while I was away as the display looked scrambled. I have replaced the control panel but it is still doing the same thing. I was wonder if there was anything else I could check? I have attached a picture.
Thanks in advance
Solution Summary
AI-generated from this discussion
This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.
Hoover washing machine showing gibberish display traced to PCB fault
- The problem
- The Hoover washing machine appeared powered while set to off, with a scrambled/gibberish display instead of normal digits or letters. The house also tripped when the machine was unplugged. Replacing the control panel did not change the fault.
- Likely cause
- A fault on the PCB is the strongest supported diagnosis. The accepted reply said the display shows what the PCB tells it, so a display fault can be caused by the PCB and/or the control panel. The original poster later confirmed finding a wasp inside the PCB housing and concluded the PCB was at fault.
- What fixed it
- The discussion supports diagnosing the PCB as faulty after the replacement control panel made no difference. The exact repair was not confirmed in the thread.
- Checks to try
- Observed machine appearing powered on while in the off position
- Observed gibberish/scrambled display with no readable error code
- Machine tripped the house when unplugged
- Control panel was replaced with a used part but the fault remained
- PCB cover was removed and a wasp was found inside
- Parts or tools mentioned
- Used control panel
- PCB
Safety: Further diagnosis should be carried out by a suitably qualified appliance engineer.

Hello. The control panel displays what the PCB tells it to so a display fault could be caused by either or both. I never recommend people replacing control panels or PCBs. They aren't cheap, you can't send them back and it's rarely 100% certain that they are the cause of the fault or the only fault.

I managed to locate the correct control panel (a used part) for £10 so I thought I'd give it a try. As for the PCB I'm not sure how lucky I will get. Thanks for the response.
Edit
It is the PCB. I had a wasp problem the same time that this died. Taking the cover off the PCB a have just found a bloody wasp in it, coincidences aren't all that real. Thanks again!
Wow. I would never have thought of that. Thanks for the update.
