GE UltraFresh Vent Smells: Cleaning Behind the Microban... | appliancefaults.com

Technical Background:

The GE UltraFresh system utilizes a vent to help dry the washer tub and prevent mold growth. The MCU controls the vent fan motor based on cycle selection and moisture sensor readings. Voltage to the vent fan motor is typically 120V AC, supplied through relays controlled by the MCU.

Symptoms:

US homeowners notice a persistent unpleasant odor emanating from the GE UltraFresh washer, specifically from the vent area even after running the cleaning cycle. The smell persists even after wiping down the visible surfaces of the drum and door seal.

Possible Causes:

Buildup of detergent residue and fabric softener in the vent system.
Mold or mildew growth due to trapped moisture.
Organic material (lint, hair) accumulation in the vent and behind the seal.
Insufficient ventilation after wash cycles allowing moisture to persist.

Solution:

1

Disconnect power to the washer at the breaker panel. Verify no voltage is present at the washer outlet using a multimeter.
2

Locate the vent system, usually accessible from the front or top of the washer after removing the access panel (requires a 1/4-inch nut driver).
3

Inspect the vent hose and surrounding area for visible buildup or mold. A borescope inspection camera can be helpful here.
4

Prepare a cleaning solution of equal parts white vinegar and hot water.
5

Gently clean behind the Microban seal with a soft brush or cloth dampened with the cleaning solution. Avoid excessive force that could damage the seal.
6

Flush the vent hose with the vinegar/water solution, ensuring proper drainage. For heavy buildup, a small amount of bleach (1/4 cup per gallon of water) can be used, but rinse thoroughly afterward.
7

Reassemble the vent system and access panels. Restore power at the breaker panel.

Safety Warning:

Lock Out/Tag Out (LOTO) the breaker before servicing. High voltage components are present. Use extreme caution when working with electrical components.

Prevention:

Regularly run the washer's cleaning cycle with a washing machine cleaner. After each wash, leave the washer door slightly ajar to promote ventilation. Avoid using excessive amounts of detergent or fabric softener.

Expert Tip:

Enter the service mode by pressing and holding the Start/Pause and Soil Level buttons simultaneously for 3 seconds. This allows you to manually activate the vent fan motor for testing and extended drying cycles. Check vent fan voltage at the motor, should read 120V AC when energized.
