Amana Washing Machine Error Code F3E2: Inlet Water... | appliancefaults.com

Technical Background:

The Main Control Unit (MCU) monitors the inlet water temperature sensor to ensure the water entering the machine is within the expected range for the selected wash cycle. The sensor is typically a thermistor, a resistor whose resistance changes with temperature. The MCU supplies a 5V DC reference voltage to the sensor, and the voltage drop across the sensor is measured. If the MCU detects a voltage outside the acceptable range, it triggers the F3E2 error code.

Symptoms:

Homeowners often report that the washing machine displays error code F3E2 and refuses to start a wash cycle. They might also notice that the water temperature seems incorrect, or that the machine fills very slowly or not at all.

Possible Causes:

Faulty inlet water temperature sensor.
Wiring harness issue between the sensor and the MCU.
Loose connection at the sensor or MCU.
Defective MCU (Main Control Unit).
Incorrect water temperature selection (Hot water feed to cold inlet).
Clogged water inlet valve screen restricting flow.

Solution:

1

Unplug the washing machine from the 120V AC power outlet.
2

Turn off both hot and cold water supply valves.
3

Disconnect the inlet hoses from the back of the washer.
4

Locate the inlet water temperature sensor. It's typically located near the water inlet valve.
5

Using a multimeter, test the sensor for resistance. A typical reading is around 10,000 ohms at 77 degrees Fahrenheit. Refer to the service manual for the exact resistance range for this specific Amana model.
6

Inspect the wiring harness and connectors for any signs of damage or corrosion. Repair or replace as needed. Use a wire stripper and crimping tool for any wire repairs.
7

If the sensor is faulty or the wiring is damaged, replace the sensor or wiring harness. Order the correct Amana replacement part.
8

Clear any clogs from the inlet valve screens. You can use a small brush or compressed air.
9

Reconnect everything, turn the water supply back on, plug the washer back in, and run a test cycle.

Safety Warning:

Always disconnect the appliance from the power source before performing any repairs. Lock Out/Tag Out (LOTO) procedures should be followed to prevent accidental energization. Some components may retain a high voltage charge even after the appliance is unplugged. Exercise caution when working near the control board.

Prevention:

Regularly inspect the water inlet hoses for kinks or damage. Clean the inlet valve screens every 6 months to prevent clogs. Use a water softener if you have hard water.

Expert Tip:

On some Amana models, you can enter service mode by pressing and holding the Start/Pause button for 3 seconds while simultaneously pressing the Cycle Select knob three times. This will allow you to run diagnostic tests and check sensor readings.

Frequently Asked Questions

•What is the correct resistance range for the inlet water temperature sensor on my specific Amana washing machine model?

Refer to the service manual or technical data sheet for your specific Amana washing machine model. The resistance range will vary depending on the model and the ambient temperature.

•How do I access the inlet water temperature sensor on my Amana washing machine?

Accessing the sensor usually involves removing the back panel of the washing machine. You may need a 1/4-inch nut driver to remove the screws. Ensure the machine is unplugged and the water supply is shut off before proceeding.

•If the inlet water temperature sensor tests good, what else could be causing the F3E2 error code?

If the sensor tests good, the issue could be with the wiring harness, a loose connection at the MCU, or a defective MCU. Carefully inspect the wiring and connections, and if necessary, replace the MCU.
