GE Profile UltraFast Combo Takes 3 Hours to Wash Jeans:... | appliancefaults.com

Technical Background:

The GE Profile UltraFast Combo's MCU controls the washing and drying cycles. The MCU monitors various sensors, including moisture, temperature, and water level, to determine the cycle progress. Voltage paths from the moisture sensor and heating element, as well as pressure sensors, all provide key feedback to the MCU.

Symptoms:

The GE Profile UltraFast Combo is taking approximately 3 hours to complete a single load of jeans. The customer reports the clothes are damp at the end of the cycle, or the wash cycle seems excessively long.

Possible Causes:

Restricted airflow in the dryer ducting.
Clogged lint filter or lint screen housing.
Faulty moisture sensor preventing the dryer from ending the cycle.
Defective heating element in the dryer not reaching proper temperature.
Inadequate water fill or slow drain affecting wash cycle timing.
Incorrect cycle selection or custom settings prolonging the drying time.

Solution:

1

Disconnect the unit from the breaker panel.
2

Inspect the dryer vent ducting for obstructions or kinks. Clean or replace as needed.
3

Clean the lint filter thoroughly. Remove and clean the lint screen housing using a 1/4-inch nut driver to remove any screws.
4

Check the heating element continuity with a multimeter. It should read between 8-12 ohms. Replace if open or shorted.
5

Locate the moisture sensor (usually in the dryer drum) and inspect for corrosion or damage. Clean with a non-abrasive pad or replace if needed.
6

Verify the water inlet valve screen is clean and not restricting water flow. Check water pressure at the inlet hoses (should be at least 20 PSI).
7

Examine the drain pump and hose for clogs. Ensure the drain hose is not kinked or restricted.

Safety Warning:

Always disconnect power at the breaker panel before servicing. High voltage components are present. Use proper LOTO procedures.

Prevention:

Clean the lint filter after every load. Inspect and clean the dryer ducting annually. Use appropriate detergent amounts to prevent excessive sudsing.

Expert Tip:

Enter service mode by pressing and holding the Start/Pause and Temp buttons simultaneously for 3 seconds. This allows you to run diagnostic tests and retrieve error codes.

Frequently Asked Questions

•What is the proper resistance range for the moisture sensor?

The resistance of the moisture sensor varies depending on the model and the moisture level. Consult the service manual for specific values. Typically, you'll be looking for a significant change in resistance as the clothes dry.

•How do I access the heating element on this model?

The heating element is usually located behind the rear access panel. You may need a 5/16-inch socket or nut driver to remove the panel screws. Be careful not to damage the thermal fuse or other components during removal.

•Where is the water inlet valve located and how do I test it?

The water inlet valve is typically located at the back of the unit, near where the water hoses connect. You can test it by disconnecting power and using a multimeter to check for continuity across the valve terminals. It should have a resistance reading. You can also apply 120V AC briefly to the valve terminals (with extreme caution!) to see if it opens.
