GE UltraFresh Washer Vent Smells: Mold Inspection and... | appliancefaults.com

Technical Background:

MCU logic and voltage paths.
The washing machine's MCU (Microcontroller Unit) controls the vent opening based on the wash cycle stage. The MCU sends a signal to the wax motor, which expands and opens the vent. A thermistor provides temperature feedback to the MCU. Voltage to the wax motor is typically 120V AC.

Symptoms:

US homeowner observations.
The GE UltraFresh washing machine vent smells musty, and there is visible mold in the detergent drawer.

Possible Causes:

Insufficient ventilation after wash cycles.
Excessive detergent usage leading to residue buildup.
Low water temperature washes that don't fully dissolve detergent.
Clogged drain pump filter preventing complete water removal.
Biofilm accumulation within the washer's internal components.
Defective wax motor controlling the vent opening.

Solution:

1

Unplug the washing machine from the 120V AC outlet and turn off the breaker.
2

Inspect the detergent dispenser drawer for mold. Remove the drawer and clean it thoroughly with a mixture of bleach and water (1 part bleach to 10 parts water).
3

Check the drain pump filter for obstructions. Remove the lower access panel (usually secured with a 1/4-inch nut driver or Phillips head screwdriver) and remove the filter. Clean it under running water.
4

Check the vent for proper function. Manually actuate the vent door and observe its movement. If it's stuck or sluggish, the wax motor might be defective. The wax motor should measure around 1500 ohms with a multimeter.
5

Run a cleaning cycle with a washing machine cleaner specifically designed to remove mold and mildew. Follow the manufacturer's instructions.
6

After the cleaning cycle, leave the washer door ajar to allow for proper ventilation and prevent moisture buildup.
7

Inspect the drain hose for any kinks or clogs. Ensure the hose is properly installed and allows for free drainage.

Safety Warning:

LOTO and high voltage warning.
Always disconnect power to the appliance before performing any repairs. Lockout/Tagout (LOTO) procedures should be followed to prevent accidental energization. High voltage components are present within the appliance. Exercise extreme caution.

Prevention:

Specific maintenance.
• Always use HE (High Efficiency) detergent and follow the manufacturer's recommended dosage.
• Regularly clean the detergent dispenser drawer.
• Run a cleaning cycle with a washing machine cleaner every month.
• Leave the washer door ajar after each wash cycle to allow for proper ventilation.
• Periodically check and clean the drain pump filter.

Expert Tip:

Trade secret or service mode sequence.
To access the GE UltraFresh service mode, simultaneously press and hold the 'Start' and 'Soil Level' buttons for 3 seconds. This will allow you to run diagnostic tests and retrieve error codes.

Frequently Asked Questions

•How often should I run the cleaning cycle?

It's recommended to run the cleaning cycle once a month to prevent mold and mildew buildup.

•What type of washing machine cleaner should I use?

Use a washing machine cleaner specifically designed for HE (High Efficiency) washers. Look for cleaners that contain bleach or other anti-fungal agents.

•How do I know if the wax motor is defective?

A defective wax motor will often be stuck or sluggish. You can test it with a multimeter. If the resistance is significantly different from around 1500 ohms, it's likely defective and needs replacement.
