Whirlpool Dryer Lint Screen Housing Full of Water:... | appliancefaults.com

Technical Background:

Moisture in the dryer vent is a normal byproduct of the drying process. The MCU controls the heating element and motor, and proper venting is essential for moisture removal. Restrictions in the vent cause backpressure and condensation, leading to water buildup. Inadequate leveling can cause water to pool.

Symptoms:

The homeowner notices water accumulating in the lint screen housing of their Whirlpool dryer after running a drying cycle. This can lead to musty odors and reduced drying performance.

Possible Causes:

Restricted dryer vent.
Incorrect dryer leveling.
Siphoning from a floor drain.
Condensation due to cold surfaces.
Leaking exhaust duct connections.

Solution:

1

Disconnect power to the dryer at the breaker panel. Use a multimeter to confirm 0V AC at the dryer receptacle.
2

Inspect the dryer vent for blockages. Use a vent cleaning brush and shop vacuum to remove lint. Measure vent length; should not exceed 25 feet equivalent with bends.
3

Check the dryer's leveling. Use a level. Adjust the leveling legs with a wrench (usually 9/16-inch) until the dryer is level in both directions.
4

Inspect the exhaust duct for proper sealing. Seal any leaks with aluminum foil tape. Ensure duct material is rigid or semi-rigid metal, not plastic.
5

Verify that the dryer vent extends at least 3 feet away from the house and has a proper termination cap with a backdraft damper.
6

If connected to a floor drain, ensure proper drain trap functionality to prevent siphoning. Add water to the trap to ensure it's primed.
7

Run the dryer on high heat for a full cycle to remove any remaining moisture. Check for water return after the cycle.

Safety Warning:

Disconnect power to the dryer at the breaker panel before performing any maintenance. Lock Out/Tag Out (LOTO) procedures should be followed. High voltage components are present inside the dryer cabinet.

Prevention:

Clean the lint screen after every load. Inspect and clean the dryer vent at least once a year. Ensure proper dryer leveling and vent connections.

Expert Tip:

Some Whirlpool dryers have a diagnostic mode. To enter it, press and hold the Start button, then press and release the following buttons in sequence within 6 seconds: MORE TIME, LESS TIME, MORE TIME, LESS TIME. Fault codes will then be displayed on the control panel.

Frequently Asked Questions

•How do I know if my dryer vent is too long?

The maximum vent length for most dryers is 25 feet equivalent, with each 90-degree bend reducing the allowable length by 5 feet and each 45-degree bend reducing it by 2.5 feet. Use a vent length calculator for accurate measurement.

•What type of dryer vent is recommended?

Rigid or semi-rigid metal duct is recommended. Plastic or foil duct is a fire hazard and should be replaced.

•How do I properly level my dryer?

Use a bubble level placed on top of the dryer. Adjust the leveling legs with a wrench until the bubble is centered. Tighten the lock nuts to secure the legs.
