Hotpoint washer/dryer display flashing on and off, likely PCB fault

The problem

Near the end of a drying cycle the machine stopped and the entire display began flashing on and off. The original poster also reported the buttons were not working.

Likely cause

The strongest diagnosis in the discussion was a fault on the main PCB and possibly the display PCB. The accepted reply suggested these boards are usually replaced as complete units rather than repaired at component level. A capacitor fault was only mentioned by the poster as a similar case seen elsewhere and was not confirmed here.

What fixed it

Accepted advice was that an engineer would typically replace the affected control board rather than repair individual electronic components. The exact failed board was not confirmed from the discussion.

Checks to try

• Visual check of capacitors on the board, with no obvious damage seen by the poster
• Observation that the display flashes on and off
• Observation that the buttons were not working
• History that the display screen had previously been replaced under warranty due to earlier problems

Parts or tools mentioned
