Panasonic Washing Machine H29 error code

Difficulty: Hard · Cost: $80–$250 · Duration: Requires professional service

The H29 error means your Panasonic washing machine detected that the cooling fan on the main PCB is running below the expected speed — typically under 1200rpm — or has stopped entirely. The cooling fan prevents the control board from overheating during operation. When it slows or stops the board is at risk of heat damage. A technician will need to inspect the fan wiring and replace the fan or board if needed.

Common causes

Cooling fan wiring is loose or has developed an open or short circuit
Cooling fan motor has slowed or failed
Power supply voltage drop causing the fan to run below normal speed
Fan blade is obstructed by debris

How to fix it

1

Unplug the machine and do not attempt to use it
2

Contact a qualified technician to inspect the cooling fan wiring and fan motor
3

If the fan checks out correctly the main control board may need replacing
