Dishwasher Making a Strange Noise?
Grinding, Rattling, Buzzing, Humming, Knocking or Squealing?
If your dishwasher has started grinding, rattling, buzzing, humming, knocking or squealing, the sound may involve a foreign object, a pump issue, the circulation system, spray-arm interference, a loose component or another mechanical fault. Electro Appliance Repairs diagnoses unusual dishwasher noises across Harare. Noise alone does not identify a pump replacement.

Why Is My Dishwasher Making a Noise?
New dishwasher noises can come from a foreign object in the sump or spray path, a pump issue, the circulation system, a spray arm hitting a rack or utensil, a loose component, or another mechanical fault. The sound may be grinding, rattling, buzzing, humming, knocking or squealing.
A noise is a useful booking detail, not a parts list. A pump is not diagnosed from sound alone. A technician needs to inspect the appliance while it is used safely.
Unusual Dishwasher Sounds
Describe the sound as clearly as you can. Different noises still need inspection.

Squealing
Possible Causes of Dishwasher Noise
Possible causes include the following. The sound does not confirm which part has worn.
- Foreign object
- Pump issue
- Circulation system
- Spray-arm interference
- Loose component
- Mechanical fault
What Can You Safely Check First?
Stop the cycle and check the base and filter area for bones, glass, bottle caps or cutlery that has fallen through a rack. Remove anything loose before running another programme.
Confirm racks are seated and that a pan is not stopping a spray arm.
Do not continue using a dishwasher that smells burnt, sparks, or makes a sudden grinding noise. Do not dismantle the pump.
If the noise started with a burning smell, sparking or a seized pump sound, stop using the dishwasher until it has been assessed.
How Dishwasher Noises Are Diagnosed
A technician can listen to the dishwasher under controlled conditions, inspect the sump for foreign objects, and check pump, circulation and spray-arm paths without assuming a pump replacement from the sound.
The repair is recommended after that inspection, not from a noise description alone.
