GE Washer E3 Error Code Troubleshooting: Shock Absorber... | appliancefaults.com

Technical Background:

The Main Control Unit (MCU) monitors the tub's movement and vibration through various sensors, potentially including shock absorber sensors. An E3 error usually indicates that the MCU has detected excessive or abnormal tub movement. The MCU operates on 5V DC logic, but the incoming power supply is 120V AC that is stepped down by the power supply board. Faulty shock absorbers cause excessive vibration, triggering the error. The voltage path from the shock absorber sensors back to the MCU may also be interrupted by a faulty sensor or wiring.

Symptoms:

Homeowners often report the washer shaking violently during the spin cycle, unusual noises, or the E3 error code displayed on the control panel. The washer may also stop mid-cycle.

Possible Causes:

Worn or damaged shock absorbers
Loose or disconnected shock absorber mounting hardware
Faulty wiring or connection to the shock absorber sensor (if equipped)
MCU (Main Control Unit) malfunction
Excessive vibration due to unbalanced load
Tub ring damage or loose tub suspension springs

Solution:

1

Unplug the washer from the 120V AC power outlet.
2

Remove the washer's top panel using a 1/4-inch nut driver.
3

Visually inspect the shock absorbers for any signs of damage, such as leaks or cracks.
4

Manually compress and extend each shock absorber. They should offer consistent resistance. If they move freely or offer no resistance, they need replacement.
5

Check the shock absorber mounting points for looseness or damage. Tighten any loose bolts or screws.
6

If the washer has shock absorber sensors, test the sensor wiring for continuity using a multimeter. Readings should match the tech sheet specifications.
7

Replace any faulty shock absorbers with OEM parts.

Safety Warning:

Always disconnect power to the appliance before performing any repairs. Use Lock-Out/Tag-Out (LOTO) procedures to ensure the washer remains de-energized during the repair. Some components operate at 120V AC, which can cause serious injury or death.

Prevention:

Avoid overloading the washer. Distribute clothes evenly in the tub. Periodically inspect the shock absorbers and suspension components for wear or damage, ideally every 6 months. Run a washer cleaning cycle with a washing machine cleaner every month.

Expert Tip:

To enter service mode on many GE washers, press and hold the Start/Pause and Delay Start buttons simultaneously for 3 seconds. This allows you to run diagnostic tests and view error history.

Frequently Asked Questions

•What is the correct OEM part number for the shock absorbers for my specific GE washer model?

The correct OEM part number can be found on the appliance's model number sticker or by searching online parts retailers using your specific model number. Always verify compatibility before ordering.

•How do I test the shock absorber sensor for proper resistance using a multimeter?

Refer to the washer's technical service manual for the correct resistance values. Disconnect the sensor and use a multimeter to measure the resistance across its terminals. Compare the reading to the specified value. An open or shorted circuit indicates a faulty sensor.

•Could a faulty tub suspension spring also cause an E3 error?

Yes, weakened or broken tub suspension springs can lead to excessive tub movement and trigger the E3 error. Inspect the springs for damage or sagging and replace them as needed. Also check the tub ring connecting the springs to the tub.
