How to Fix F7/E1 Error Code on Whirlpool Top Load Washer (Maytag, Amana, Kenmore)

If you’re seeing the F7/E1 error code on your top-loading washer, you’re not alone! This error, which indicates a “Tachometer Missing or Wrong Signal,” affects certain models by Whirlpool and can appear on Maytag, Amana, Kenmore, and Crosley washers. Below, we’ll go through the common causes and solutions to this common error code.

What Does the F7/E1 Error Code Mean?

The F7/E1 code is triggered when your washer’s Appliance Control Unit (ACU) cannot detect the speed of the drum through the tachometer, an essential component that helps the washer manage spin cycles and other operations. Without this signal, your washer can’t function properly, leading to errors and operational issues.

Most Common Causes and Solutions

Here are the top causes of the F7/E1 error code and steps you can take to fix them:

1. Bad Shift Actuator or Optical Speed Sensor Failure

   The optical sensor, which monitors drum speed, is integrated into the shift actuator. If the shift actuator fails, it can cause the optical sensor to stop sending signals, leading to the F7/E1 error code. Replacing the shift actuator usually resolves this issue.

2. Bad Motor Run Capacitor

   Another common cause of the F7/E1 error is a faulty motor run capacitor, which helps the motor start and operate efficiently. Most motor run capacitors should measure around 50 microfarads (µF) – you can find the exact rating printed on the capacitor. To check if it’s functioning correctly, use a multimeter capable of measuring capacitance. If your capacitor doesn’t measure correctly, it may need to be replaced.
