Whirlpool Dishwasher: not draining properly
What is this symptom?
Is your Whirlpool dishwasher not draining properly, leaving water at the bottom after a wash cycle? This issue often leads to unpleasant odors and may indicate a clogged filter, a blocked drain line, or a malfunctioning drain pump. Understanding the causes can help you troubleshoot effectively.
Important Tips for Whirlpool Models
- Newly installed Whirlpool dishwashers require removal of the dishwasher-to-disposal knockout plug; failure can cause non‑draining.
Possible Causes
Clogged filter or drain basket
How to Identify: Standing water after cycle and visible food debris around the bottom or filter area.
Part: Dishwasher filter / drain basket
Garbage disposal or drain line blockage / knockout plug not removed
How to Identify: Dishwasher connected to disposal and disposal backflow or plug left intact, causing dishwasher water not to exit.
Part: Garbage disposal / drain connection
Failed or obstructed drain pump
How to Identify: Pump makes humming or no noise when it should be draining, or water remains despite clear hoses and filters.
Part: Drain pump / motor
Blocked or stuck drain valve
How to Identify: Pump runs but water doesn’t exit; the valve doesn’t open properly.
Part: Drain valve
