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

Technical Background:

The dryer's exhaust system removes moisture-laden air. When airflow is restricted, humidity builds up within the dryer drum and vent. In cold conditions, this humidity can condense into water within the vent, especially at low points or restrictions, eventually draining back into the lint screen housing. The MCU (Main Control Unit) monitors temperature sensors, but doesn't directly detect water accumulation.

Symptoms:

US homeowners often report finding standing water in the lint screen housing after running their Whirlpool dryer. This can be accompanied by longer drying times, damp clothes, and a musty odor. Some may also notice condensation on the dryer door or surrounding surfaces.

Possible Causes:

Restricted or blocked dryer vent.
Long or improperly installed dryer vent.
Outside vent flapper stuck closed.
Insufficient airflow around the dryer.
Kinked or crushed dryer vent hose.
Dryer installed in an unheated space during cold weather.

Solution:

1

Unplug the dryer from the 120V AC outlet.
2

Disconnect the dryer vent from the back of the dryer.
3

Inspect the dryer vent for blockages. Remove any lint buildup using a vent brush. Ensure there are no bird nests or other obstructions.
4

Check the outside vent flapper. Make sure it opens and closes freely. Clean if necessary.
5

Verify the dryer vent run is within the manufacturer's recommended length (typically less than 25 feet with minimal bends).
6

Replace any kinked or crushed vent hoses with rigid or semi-rigid metal ducting.
7

Ensure adequate airflow around the dryer. Clear any obstructions that might be blocking the dryer's air intake.
8

Reconnect the dryer vent and plug the dryer back into the outlet.

Safety Warning:

Disconnect power to the dryer before performing any maintenance or repairs (Lock Out/Tag Out - LOTO). The dryer operates on 120V AC, which can cause serious injury or death. If you are not comfortable working with electrical appliances, contact a qualified technician.

Prevention:

Clean the lint screen after every load. Inspect and clean the dryer vent at least once a year, or more frequently if drying times increase. Use rigid or semi-rigid metal ducting for the dryer vent to prevent kinking and crushing.

Expert Tip:

To check the dryer's exhaust temperature, run the dryer on a timed cycle (high heat) for 15 minutes. Use an infrared thermometer to measure the temperature of the exhaust air exiting the dryer vent. A normal exhaust temperature should be between 120-190 degrees Fahrenheit. Higher temperatures indicate a restricted vent.

Frequently Asked Questions

•How often should I clean my dryer vent?

You should clean your dryer vent at least once a year. If you notice longer drying times or excessive lint buildup, you may need to clean it more frequently.

•What type of dryer vent hose is best to use?

Rigid or semi-rigid metal ducting is the best option for dryer vents. It is more resistant to kinking and crushing than flexible foil or plastic hoses, which can restrict airflow.

•Can a clogged dryer vent cause a fire?

Yes, a clogged dryer vent is a serious fire hazard. Lint is highly flammable, and a buildup of lint in the vent can ignite due to the heat from the dryer.
