Blomberg Dishwasher: not stopping draining
What is this symptom?
If your Blomberg dishwasher is not stopping draining, it may be due to a clogged drain filter or an issue with the control board. This can lead to the drain pump running continuously, disrupting your cleaning cycle. Understanding the causes can help you troubleshoot the issue effectively.
Important Tips for Blomberg Models
- Official Blomberg documentation focuses on drainage blockages (filters, hoses) but does not explicitly describe continuous drain pump behavior; no official symptom-specific guide found
Possible Causes
Clogged drain filter or debris preventing normal completion of drain cycle
How to Identify: Food debris visible in the filter area; water remains at bottom requiring prolonged pump run; dishwasher makes continual pump sounds
Part: Drain filter / sump area
Control board or electronic control misinterpreting cycle stage
How to Identify: Pump runs unrelated to actual drainage needs, no blockages found, error codes displayed or no display feedback
Part: Main control board
DIY Solutions
Clean drain filter and sump area
- Turn off power to the dishwasher.
- Remove the bottom rack to access the filter area.
- Twist and lift out the drain filter and any removable screens.
- Rinse the filter under running water and scrub off debris with a brush.
- Reinstall the clean filter and run a short cycle to test.
Inspect and clear drain hose
- Turn off power and water to the dishwasher.
- Locate the drain hose under the sink or at the back of the dishwasher.
- Inspect for kinks and straighten hose if bent.
- Disconnect the hose and flush with water or use a flexible brush to remove debris.
- Reconnect securely and test the dishwasher.
