Maytag Washer Error Code E335

E335 indicates that the heatsink on the frequency inverter has exceeded its maximum allowed temperature. The inverter controls motor speed and relies on a cooling fan and fin assembly to stay within safe thermal limits. When that cooling system fails or is compromised, the washer stops and displays E335 to prevent damage to the inverter electronics.

No, you should not continue running the washer while E335 is active. The error indicates that the inverter is overheating, and continued operation without addressing the cause can result in permanent damage to the inverter board. Allow the machine to cool down before attempting diagnostics and do not bypass the shutdown.

Repair costs depend on the failed component. Replacing the inverter cooling fan is generally the least expensive fix, typically ranging from $50 to $150 including parts and labor. If the inverter board itself needs replacement, costs can range from $200 to $450 or more depending on the model and whether a technician is hired. Cleaning blocked fins or improving ventilation involves no parts cost at all.

Start by checking whether the inverter cooling fan is running during operation. If the fan is not spinning, it may need to be replaced. Also inspect the heatsink fins for dust or lint buildup and clean them with compressed air. Ensure the washer has adequate ventilation space around it, and if those steps do not resolve the issue, the temperature sensor or inverter board itself may need to be tested or replaced.

A reset may temporarily clear the code, but the error will return if the underlying cause has not been fixed. If the cooling fan is not functioning or airflow remains restricted, the heatsink will overheat again during the next cycle and E335 will reappear. Always resolve the root cause before relying on a reset.
