Maytag Washer Error Code E29

E29 indicates an OV3/E.OP overvoltage timeout fault from the frequency inverter, which is the component that controls motor speed. The fault means the inverter detected a voltage level beyond its safe operating range and was unable to resolve it within the allowed timeout period. This is a protective shutdown designed to prevent damage to the motor and drive electronics.

No, you should not attempt to run the washer while E29 is active. The fault indicates an uncontrolled overvoltage condition inside the inverter circuit, which poses a risk of further damage to the motor, control board, or other electrical components. The machine has shut down as a protective measure and should remain out of service until the fault is resolved.

Repair costs vary depending on the cause. If the fix is simply correcting a configuration setting, there may be no parts cost at all, though a service call to diagnose the issue typically runs in the range of $75 to $150. If the frequency inverter board needs replacement, parts and labor combined can range from $200 to $450 or more depending on the model and local labor rates.

The first step is to check the Machine Type setting in the Configuration Menu, which is something a knowledgeable DIYer can do without tools. If the configuration is correct, diagnosing and repairing the frequency inverter or electrical supply issues typically requires a multimeter, technical familiarity with motor drive components, and comfort working with line voltage. If you are not experienced with appliance electrical systems, it is safer to call a qualified technician.

A power cycle reset may temporarily clear the fault display, but the E29 code is likely to return if the underlying cause has not been corrected. Because the fault is specifically described as one the inverter cannot handle on its own, the root cause, whether it is a configuration error, supply voltage issue, or hardware failure, must be addressed for the repair to hold.
