Admiral Washer Error Code F3E2: Inlet Water Temperature... | appliancefaults.com

Technical Background:

The MCU monitors the inlet water temperature sensor to ensure proper water temperature for the selected wash cycle. The sensor sends a resistance signal to the MCU, which interprets the temperature. If the MCU detects an out-of-range temperature reading or a lack of signal, it triggers the F3E2 error. The sensor typically operates on a 5V DC circuit from the MCU.

Symptoms:

The homeowner reports the washer displays error code F3E2 during the wash cycle. The washer may not fill properly, or the water temperature may be incorrect. Cycles may be interrupted.

Possible Causes:

Faulty inlet water temperature sensor
Wiring harness issue between the sensor and the main control unit (MCU)
Corroded or loose connector at the sensor or MCU
Defective MCU
Water supply issue affecting water temperature
Excessive scaling or mineral buildup on the sensor

Solution:

1

Disconnect power to the washer at the breaker panel.
2

Locate the inlet water temperature sensor, typically near the water inlet valve. It often has a blue or white connector.
3

Inspect the wiring harness and connector for any signs of damage, corrosion, or loose connections. Clean or repair as needed.
4

Disconnect the sensor and use a multimeter to measure its resistance. A typical sensor should read between 10k and 50k ohms at room temperature (70°F). Refer to the service manual for the exact specifications.
5

If the sensor resistance is outside the specified range, replace the sensor. Use a 1/4-inch nut driver to remove any mounting screws or clips.
6

If the sensor tests good, check the wiring continuity from the sensor connector to the MCU connector. Use a multimeter on the continuity setting.
7

If the wiring is good, the MCU may be faulty. Replacement of the MCU may be needed, but licensed technician diagnosis is recommended before replacing expensive parts.

Safety Warning:

Always disconnect power to the appliance at the breaker panel before performing any repairs. Lock Out/Tag Out (LOTO) procedures should be followed. Some components may retain a high voltage even after the appliance is unplugged.

Prevention:

Periodically check the water inlet hose screens for debris and clean them as needed. This helps ensure proper water flow and reduces stress on the temperature sensor. Inspect the sensor and wiring connections annually for any signs of corrosion or damage.

Expert Tip:

On some Admiral models, you can access a diagnostic mode by pressing and holding the Start/Pause and Temp buttons simultaneously for 3 seconds. This may provide more detailed error information or allow you to run diagnostic tests.

Frequently Asked Questions

•What is the exact resistance value I should be looking for on my inlet water temperature sensor at 70°F?

The resistance value varies slightly by model. Refer to the service manual for your specific Admiral washer model. However, a typical range is between 10k and 50k ohms at 70°F. Some sensors may have a specific value like 25k ohms +/- 5k ohms.

•How do I access the main control unit (MCU) on my Admiral washer?

The MCU is usually located behind the control panel. You will need to remove the screws securing the control panel to the washer cabinet. Be careful not to damage any wiring when removing the control panel. A 5/16-inch socket or nut driver is usually needed.

•If the sensor and wiring test good, and I suspect the MCU is faulty, is there a way to confirm this before replacing it?

A professional appliance technician can use specialized diagnostic tools and procedures to further test the MCU. This might involve checking voltage levels, signal outputs, and communication between the MCU and other components. Without these tools and expertise, it's difficult to definitively confirm an MCU failure. Replacing the MCU without proper diagnosis can be an expensive and unnecessary repair.
