Amana Washer Error Code F7E1: Basket Speed Sensor Fault... | appliancefaults.com

Technical Background:

The MCU (Main Control Unit) relies on the basket speed sensor to monitor the speed of the wash basket during the spin cycle. The sensor typically sends a pulsed DC voltage signal back to the MCU. The MCU uses this signal to regulate motor speed and detect any abnormalities. The voltage path is typically 5V DC from the MCU to the sensor, and a return signal to the MCU.

Symptoms:

The washer displays an F7E1 error code. The washer may not spin properly, or the spin cycle may be intermittent or not function at all. The basket might be jerky or make unusual noises during the spin cycle.

Possible Causes:

Faulty basket speed sensor
Wiring harness issue between the sensor and the control board
Loose connection at the sensor or control board
Damaged control board (MCU)
Obstruction interfering with basket rotation
Incorrect drive motor operation.

Solution:

1

Disconnect power to the washer at the breaker panel.
2

Locate the basket speed sensor. It's typically near the motor or drive assembly. Refer to the service manual for your specific Amana model.
3

Inspect the wiring harness and connectors leading to the speed sensor for any visible damage, corrosion, or loose connections. Secure any loose connections and repair damaged wiring.
4

Using a multimeter, check the resistance of the speed sensor. Consult the service manual for the correct resistance range. A reading outside the range indicates a faulty sensor.
5

If the sensor tests within range, reconnect power and use a multimeter to check the voltage at the sensor connector on the control board during a spin cycle. Look for approximately 5V DC. No voltage suggests a control board issue.
6

If the sensor is faulty, replace it with a new one. Ensure the replacement sensor is compatible with your Amana washer model.
7

If the control board is suspected, replace it with a new one. This requires careful programming on some models. Consult the service manual or a qualified technician.

Safety Warning:

Always disconnect the power supply to the washer before performing any diagnostic or repair procedures. Use proper Lock Out/Tag Out (LOTO) procedures to prevent accidental re-energization. Be aware of high voltage components within the washer. Wear appropriate safety glasses and gloves.

Prevention:

Periodically inspect the washing machine for any signs of damage, such as frayed wires or loose connections. Ensure the washer is level and not overloaded, as excessive weight can strain the motor and sensor. Clean the area around the sensor to prevent debris buildup.

Expert Tip:

Many Amana washers have a diagnostic mode. To enter diagnostic mode, typically you press and hold the Start/Pause button, then quickly press the Cycle Select button three times within 5 seconds. This will allow you to cycle through error codes and test individual components like the speed sensor.

Frequently Asked Questions

•What is the typical resistance range I should see on the basket speed sensor?

The resistance range varies by model, but typically falls between 500-2000 ohms. Consult the service manual for your specific Amana washer model.

•How do I know if the control board is sending the correct voltage to the sensor?

Using a multimeter set to DC voltage, carefully back-probe the connector at the control board while the machine is attempting to spin. You should see approximately 5V DC.

•Where can I find the service manual for my specific Amana washer model?

You can usually find the service manual online by searching for your model number followed by 'service manual' or 'repair manual.' AppliancePartsPros.com and similar sites often have them available for free download or purchase.
