What does the E3 code mean on the 540 model and is there a fix?

SOURCE: Code E3

The Machine control is attempting to drive the motor but is not seeing any tachometer response or motor action. It could have a failed tachometer/hall sensor which is part of the motor, failed motor or machine control. It could be a loose wire connection at the motor or at the machine control board. This type of failure will require a technician to diagnose and repair your washer. I recommend calling a service technician.

SOURCE: We are getting error code E3. What does this mean

Looks like you have either a stuck drum (does not spin) or an electrical fault that make the washer think the drum is not moving.

From a 2006 Technical Bulletin:

E3: Machine control is attempting to drive the motor but is not seeing any tach response. Visual Check shows motor is not moving. (Locked or Hall Sensor fault.)

Specifically, it could be:

1. Spin drum stuck – Verify that the spinner moves freely to eliminate this cause.
2. Hall Sensor (integral part of motor) fails or is loose – When the Hall Sensor fails or becomes dislodged, the control doesn't recognize that the motor is spinning and shuts down. The result will likely be an “E3” code in the worst case, or “SUdS” if it is only getting a partial rpm reading. Check wire harness connector(s) to motor.

Unless you are really overloading your machine you likely have an electrical fault, or a failure in the drive train--especially if the problem is intermittent. Probably time to call in a technician.
