Amana Dishwasher: pump failure
What is this symptom?
Experiencing pump failure in your Amana dishwasher? This issue can lead to standing water after cycles, lack of water circulation, or unusual noises. Common causes include a clogged pump or impeller, a faulty pump motor, or issues with the electrical control board. Understanding these symptoms can help you troubleshoot effectively.
Important Tips for Amana Models
- Official troubleshooting guides do not provide detailed pump failure steps; community sources note typical causes similar to general dishwashers.
- Control board can prevent drain pump activation on Amana models.
Possible Causes
Clogged pump/impeller due to debris
How to Identify: Standing water at bottom after cycle, unusual grinding or buzzing noise from bottom of dishwasher during operation, visible debris when accessing pump housing.
Part: Dishwasher pump (drain or circulation pump) impeller
Faulty pump motor
How to Identify: No pump noise at expected drain/circulation times; humming without pumping; consistent failure across cycles after filter/hose cleared.
Part: Dishwasher pump motor
Electrical/control board issue preventing pump activation
How to Identify: No signal to pump despite correct cycle selection and power, intermittent operation not correlated to debris, issues persist after clearing clogs.
Part: Electronic control board / relay
Clogged drain hose or filter mimicking pump failure
How to Identify: Standing water but clear pump impeller; kinks or blockages in drain hose; debris caught in filter causing reduced flow.
Part: Drain hose, filter assembly
DIY Solutions
Clear debris from filters and pump area
- Turn off power and water supply.
- Remove bottom rack and filter assembly; rinse and remove debris.
- Access pump housing (usually behind filter) and remove debris from impeller area manually.
- Reassemble filter and bottom rack; restore power and test dishwasher.
Inspect and straighten drain hose
- Disconnect power to dishwasher.
- Locate drain hose behind the dishwasher.
- Check for kinks and straighten hose; if accessible flush with water to clear obstructions.
- Reconnect hose securely and restore power; run a short cycle to test.
