What does GE GTW720BSNWS Washer Problems & Error Codes mean?

Motor and drive system faults are most common, causing codes 5, 6, 8, or 10. Check belt, motor, mode shifter, and control board wiring in diagnostic mode.

How do I fix GE GTW720BSNWS Washer Problems & Error Codes?

Work through the step-by-step fix below. Start with the quick reset and the most common cause, then check the specific part this guide points to. Most fixes need only basic hand tools and the right replacement part.

Can I keep using my GE appliance with this error showing?

Usually not. GE appliances show this error when a part or safety circuit is out of range, so running it can stop the cycle or make the problem worse. Diagnose and clear the error before normal use.

What part is most commonly replaced for GE GTW720BSNWS Washer Problems & Error Codes?

The parts that most often fix GE GTW720BSNWS Washer Problems & Error Codes are listed in the parts section of this guide. Match the part to your exact model and serial number before you buy.

Is GE GTW720BSNWS Washer Problems & Error Codes a DIY repair or do I need a technician?

Many fixes are DIY-friendly with basic tools, such as door switches, drain pumps, water inlet valves, thermostats, heating elements, and filters. Sealed-system, refrigerant, gas, or high-voltage work should go to a licensed technician for safety.

GE GTW720BSNWS Washer Problems & Error Codes

GE GTW720BSNWS Washer Problems & Error Codes — Overview

The GE GTW720BSNWS is a 4.8 cu. ft. top-load washer with electronic controls, FlexDispense, and Sanitize w/Oxi cycles. Like other GE top-loaders in this platform, it uses a hidden diagnostic mode that stores numbered fault codes to help pinpoint motor, drive train, and control failures. Motor-related codes (2, 5, 6, 8, 9, and 10) are the most frequent problems on this model, along with mode shifter and communication faults between the motor and control board.

Jump to Common Problems

Most Common Problems on This Model

Motor locked or won’t spin (code 6) The motor or drive train is bound up by a seized mode shifter, locked transmission, or failed motor, so remove the belt and test whether the pulley turns freely by hand to isolate the motor from the actuator.
No communication between motor and control (code 10) Wiring or connectors between the motor and timer/control board are damaged or loose, or the control board itself has failed, blocking all motor signals.
Motor problem or overheating (codes 5 or 8) The motor itself is failing, the drive train is binding and overloading the motor, or the belt is contaminated and causing excessive drag during spin.
Belt slipping during agitation or spin (code 2) The drive belt is worn, stretched, contaminated with detergent or grease, or the pulleys are dirty, so replace the belt and clean the pulley grooves.
Mode shifter failure or can’t switch cycles (code 4) The mode shifter actuator (which moves the transmission between agitate and spin) is stuck, broken, or not receiving power from the control board.
Brake resistor failure (code 9) The motor brake resistor has burned out or opened, preventing the motor control from safely decelerating the spin basket.
Tub takes more than 25 seconds to stop (code 1) The brake mechanism, clutch assembly, or motor control is not decelerating the basket correctly, often due to a worn clutch or resistor fault.
Lid not opened after four wash cycles (code 7) The lid switch is stuck closed, preventing the washer from detecting that the lid was lifted, or the control board has logged repeated continuous-run events.

Parts That Commonly Fail

Part	Notes
Drive motor	Amazon \| Fails with locked rotor, overheating, or communication loss to the control board, causing codes 5, 6, 8, or 10.
Mode shifter actuator	Amazon \| Sticks or breaks, preventing the transmission from switching between agitate and spin modes (code 4 or 6).
Drive belt	Amazon \| Stretches, cracks, or gets contaminated, causing slipping, noise, or incomplete spin cycles (code 2).
Main control board or timer	Amazon \| Loses communication with the motor, fails to send power to components, or corrupts diagnostic data (code 10).

When to Call a Pro

Call a tech if you cannot access diagnostic mode, if stored fault codes point to the motor or control board and you are not comfortable with live voltage testing, or if the drive train is mechanically seized and you need to disassemble the transmission or clutch. Any repair that requires removing the cabinet, testing motor windings, or replacing the main control board is safer and faster with a technician who has the service manual and the correct part numbers for your control version.
