Whirlpool Dishwasher: leaking, not draining
What is this symptom?
Is your Whirlpool dishwasher leaking and not draining properly? You may notice water pooling at the bottom or leaking from the door. Common causes include clogged filters, kinks in the drain hose, and faulty seals. Addressing these issues promptly can prevent further damage and odors from stagnant water.
Important Tips for Whirlpool Models
- New installations often suffer from missing garbage disposal knockout plug or improper drain hose routing (high loop/air gap).
Possible Causes
Clogged drain filter and sump
How to Identify: Standing water after drain cycle with visible debris around the filter; foul odors; performance improves temporarily after cleaning.
Part: Dishwasher drain filter/sump area
Clogged or kinked drain hose
How to Identify: Water remains in tub; water backing up into sink; visible kinks or bends in hose under sink; blockage when flushed through hose.
Part: Drain hose to garbage disposal or drain
Garbage disposal mis‑installation or blockage
How to Identify: Dishwasher water not draining and disposal inlet plug not removed or disposal clogged; running disposal clears backup.
Part: Garbage disposal/dishwasher drain connection
Faulty drain pump or pump impeller
How to Identify: Humming from pump without water removal; debris not visible in hose/filter; no drain activity despite cycle progression.
Part: Drain pump assembly
Damaged or stuck drain valve
How to Identify: Pump runs but water remains; valve doesn’t open when tested; partial or very slow drain.
Part: Drain valve
Door gasket or door seal failure causing leakage
How to Identify: Water visible around door edge during cycles; gasket shows cracks, gaps, or uneven sealing.
Part: Door gasket/door seal
Loose or damaged hoses/clamps inside unit causing leaks
How to Identify: Water on floor under dishwasher not clearly from door; visible wear on hoses when inspected.
Part: Internal hoses and clamps
