Asko Dishwasher: grinding noise
What is this symptom?
Hearing a grinding noise from your Asko Dishwasher? This unsettling sound typically occurs during wash or drain cycles and often indicates mechanical friction or an obstruction within internal components like the pump or impeller. Identifying the root cause early can prevent further damage and ensure your dishwasher operates smoothly.
Important Tips for Asko Models
- Asko official support notes that if impeller or motor bearings fail, the entire circulation pump assembly may need replacement; some models allow impeller replacement separately. (Asko Appliance Support
- Obstructions like utensils can cause noisy operation and grinding if wash arms hit items; ensure loads do not block spray arms. (Asko Appliance Support
Possible Causes
Foreign object (debris) jammed in pump/impeller or chopper area
How to Identify: Grinding occurs when debris such as glass shards, fruit pits, utensils falls into lower sump/filter area and noise often correlates with the pump trying to spin.
Part: Drain or circulation pump impeller, chopper blade
Damaged or worn wash/drain impeller
How to Identify: Grinding that persists after debris removal; impeller blades broken, warped, or rubbing against housing when inspected visually. (askoappliance.support
Part: Wash impeller / drain impeller
Worn motor bearings in circulation or drain pump
How to Identify: Continuous grinding or droning noise even with no debris present; noise appears during wash cycles and is mechanical in nature.
Part: Circulation/drain pump motor bearings
