GE UltraFresh Vent Smells Like Damp Towels: Airflow... | appliancefaults.com

Technical Background:

The GE UltraFresh washer utilizes a vent system controlled by the main control unit (MCU). The MCU monitors moisture levels and activates the vent fan to dry the internal components. Voltage is supplied through a relay on the MCU. Malfunctions can occur due to component failure, clogged hoses, or sensor issues, leading to improper vent operation and odor buildup.

Symptoms:

The GE UltraFresh washer emits a persistent damp towel smell from the vent, even after running cleaning cycles. Airflow from the vent may be weak or non-existent.

Possible Causes:

Clogged or restricted vent hose
Blocked or dirty drain pump filter
Excessive detergent usage
Biofilm buildup in the drum and hoses
Faulty air vent system
Incorrect laundry practices (leaving wet clothes in the washer)

Solution:

1

Disconnect the washer from the power outlet and water supply.
2

Inspect the vent hose for kinks, clogs, or obstructions. Remove any debris.
3

Locate and clean the drain pump filter. Remove any lint, hair, or debris. Use a 5/16-inch socket to remove the access panel.
4

Run a washer cleaner cycle with a washing machine cleaner according to the manufacturer's instructions. Use a product like Affresh or similar.
5

Check the air vent system for proper operation using a multimeter to check the voltage to the vent fan motor (should be 120V AC when the vent is active). Replace if faulty.
6

Sanitize the washing machine drum using a bleach cycle (check the user manual for specific instructions).
7

Ensure proper ventilation in the laundry room. Consider installing a dehumidifier.

Safety Warning:

Disconnect power at the breaker panel before performing any repairs. High voltage (120V AC) is present in the appliance. Use proper Lock Out Tag Out (LOTO) procedures to prevent accidental energization.

Prevention:

Regularly clean the drain pump filter (every month). Use the correct amount of HE detergent. Run a washer cleaning cycle monthly. Leave the washer door slightly ajar after each use to promote airflow.

Expert Tip:

Enter service mode by pressing and holding the Start/Pause and Option buttons simultaneously for 3 seconds. This allows you to run diagnostic tests on the vent system and other components.

Frequently Asked Questions

•How often should I clean the drain pump filter?

The drain pump filter should be cleaned monthly or more frequently if you notice slow draining or excessive lint buildup.

•What type of washer cleaner is recommended for the GE UltraFresh?

Use a washing machine cleaner specifically designed for HE (High Efficiency) washers, such as Affresh or a similar product.

•How do I know if the air vent fan motor is faulty?

Use a multimeter to check for 120V AC at the motor when the vent is supposed to be active. If voltage is present but the motor isn't running, the motor is likely faulty and needs replacement.
