Maytag Washer Error Code 31: What It Means and How to Fix It

Maytag washer error code 31 generally indicates a communication failure between the central control unit and the motor control unit, requiring a power reset or wiring check.

What does the error code 31 mean on a Maytag washer?

Error code 31 on a Maytag washer signifies a communication error between the main control board and the motor control unit.

When your washer cannot properly send or receive signals between its primary electronic components, it halts the cycle to prevent internal damage. Because error code definitions can vary by specific model line and production year, you should always double-check your owner’s manual or the manufacturer support page for exact details.

• Indicates a disruption in the digital data stream between internal boards.
• Stops the current wash cycle immediately to prevent electrical issues.
• May appear intermittently if a loose connection makes temporary contact.
• Can be triggered by temporary power surges or electrical glitches.
• Requires verifying specific model guidelines as wiring layouts differ.

Why does Maytag washer error code 31 happen?

This error typically occurs due to temporary software glitches, loose wiring harnesses, or failing control boards.

Electronic appliances rely on steady voltage and secure wiring harnesses to transmit commands from the user interface down to the drive motor. Over time, heavy spin cycle vibrations can loosen these delicate internal connections, or a sudden electrical surge can freeze the internal processor.

• Loose wiring harnesses caused by continuous machine vibration during spinning.
• Temporary electronic glitches or data freezes on the main control board.
• Corroded terminal pins on the motor control unit connector plugs.
• Power fluctuations that interrupt normal communication loops.
• Component failure on either the main board or the motor inverter.

How do you perform a quick reset to clear error code 31?

Unplug the washer for two to three minutes to completely drain residual voltage and reset the control boards.

Before checking internal components, you must remove power to protect yourself against electric shock and allow the computer memory to clear completely. Unplug the appliance from the wall outlet or turn off the dedicated circuit breaker before touching internal parts.

1. Unplug the washing machine power cord from the electrical wall outlet.
2. Wait for at least three full minutes to let all internal capacitors discharge.
3. Press and hold the power or start button for five seconds to drain residual energy.
4. Plug the washing machine power cord securely back into the wall outlet.
5. Run a short test cycle to see if error code 31 reappears on the display.

What are the next troubleshooting steps if the reset fails?

Inspect and secure internal wiring harnesses connecting the main control board to the motor.

If a simple power reset does not restore communication, you will need to inspect the physical wiring. Always unplug the appliance or turn off the breaker before removing any panels to expose internal wiring harnesses and control boards.

1. Unplug the washing machine from the electrical outlet before removing any service panels.
2. Remove the rear access panel or top panel using a standard screwdriver.
3. Locate the wiring harness running between the main control board and the motor.
4. Unplug each connector plug, check for corrosion or damage, and push them firmly back together.
5. Reinstall the service panels securely and plug the washing machine back into power.

Which fix matches your specific Maytag washer symptom?

Match your washer symptom to the corresponding repair action to quickly resolve communication issues.

Symptom	Likely cause / fix
Code appears instantly	Perform a 3-minute power reset.
Code returns after cycle starts	Check motor wiring harness connections.
Dim or flickering display	Verify steady outlet voltage.
Intermittent code during spinning	Secure loose internal terminal plugs.

When should you stop troubleshooting and call a professional technician?

Call a technician if you find burnt control board components, damaged wiring, or if the error persists.

Appliance repair involving electronic circuit boards requires specialized diagnostic tools and replacement parts. Stop working immediately and contact a licensed service technician if basic resets and harness checks do not resolve the communication failure.

• Visible burn marks or melted plastic on the main control board.
• Frayed, cut, or severely damaged internal wiring harnesses.
• The error code returns immediately after professional-level resets.
• You feel uncomfortable or unsafe performing internal electrical checks.
• The appliance is covered under an active manufacturer or extended warranty.

What information should you have ready before calling for service?

Gather your exact model number, serial number, warranty details, and troubleshooting history before calling.

Having the correct appliance information ready helps customer service dispatch the right technician with compatible replacement parts on the first visit. You can typically find the model and serial number sticker located around the main door opening.

• Locate the exact model number and serial number on the appliance door frame tag.
• Note the exact error code number displayed on your machine control panel.
• List all the troubleshooting steps you have already attempted.
• Gather your original purchase receipt and active warranty documentation.
• Prepare a description of when the error code first started appearing.

How can you prevent Maytag washer error code 31 from returning?

Prevent future communication errors by ensuring stable power supply and minimizing heavy machine vibrations.

Protecting your washer’s sensitive electronic control boards helps extend the lifespan of the appliance and prevents recurring error codes. Simple maintenance habits keep internal connections secure and protect against harmful electrical spikes.

• Plug your washing machine directly into a wall outlet without using extension cords.
• Level all four washer feet correctly to reduce excessive vibration during spin cycles.
• Use a surge protector rated for heavy household appliances to block voltage spikes.
• Avoid overloading the wash drum to prevent severe mechanical strain on the drive system.
• Keep the laundry area dry to prevent moisture buildup around electronic components.
