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. 1

    Unplug the machine and do not attempt to use it

  2. 2

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

  3. 3

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