How to Fix / Troubleshooting
Safety first: Disconnect power before accessing pumps.
- 1. Determine when noise occurs: Note if the noise happens during wash (circulation pump) or drain (drain pump).
- 2. Check water level: Ensure the dishwasher is filling to the correct level; a low level can cause cavitation noise. If low, inspect the inlet system.
- 3. Inspect pumps: Access the relevant pump and check for debris or signs of water ingress into the motor.
- 4. Replace pump: If bearings are noisy or there is play in the shaft, replace the Haier pump assembly.
- 5. Test after replacement: Run a full cycle to confirm the noise is resolved.
Warning: Ignoring bearing noise can lead to pump seizure and leaks.
