Maytag Washer Error Code E318

E318 on a Maytag washer indicates a CPU Fault 6, which is an internal inverter fault. The washer's main control board has detected a problem within the inverter board, the component that regulates motor speed and direction. The machine stops operation when this fault is active to protect the drive system from further damage.

You should not continue running the washer while E318 is active. The fault indicates an internal failure in the inverter, and operating the machine in this condition could worsen the damage to the drive system. Stop using the washer until the fault has been properly diagnosed and resolved.

A reset may clear the E318 error temporarily if the fault was caused by a one-time electrical transient or intermittent condition. However, if the inverter board has an actual internal failure, the fault will return when the washer attempts to run the motor. A persistent E318 that comes back after resetting confirms the inverter board needs to be replaced.

If the fault is intermittent, clearing the error and running a cycle may resolve it temporarily. However, if the E318 returns consistently, the inverter board has an internal failure and needs to be replaced. Replacing the inverter board involves working near high-voltage components, so comfort with appliance electrical repairs is required. If you are unsure, scheduling a professional technician is the safer option.

Repair costs will vary depending on your location and whether you hire a technician or do the work yourself. Inverter board parts typically range from roughly 80 to 250 dollars depending on the specific model. Adding professional labor, total repair costs commonly fall in the range of 150 to 400 dollars. Getting a quote from a local appliance repair service before committing is always a good idea.
