Possible Causes

Low mains voltage affecting inlet valve, Very low water pressure, Faulty inlet valve coil, Loose power connections

How to Fix / Troubleshooting

Safety first: Unplug the washer before checking electrical connections.

Steps to check and address E29:

  • Check household supply: Confirm that other appliances and lights are not dimming; if they are, contact an electrician to check supply voltage.
  • Verify water pressure: Ensure taps are fully open and that water flow is strong.
  • Inspect inlet valve wiring: Remove the top cover and check that the inlet valve connector is secure.
  • Test inlet valve coil: Measure resistance; replace the valve if the coil is open or out of spec.

When to call a technician: Persistent E29 with good water and voltage may indicate a control board issue requiring professional service.
