Maytag Washer Error Code E315

E315 indicates that the frequency inverter, the component that controls motor speed, is not receiving operational requests from the main washer control board. This communication failure causes the washer to stop and display the fault code. The issue typically originates in the power supply contactor, the wiring harness, the inverter, or the control board itself.

No, you should not continue operating the washer while E315 is active. The fault means the motor control system is not functioning correctly, and running the machine in this state could cause further damage to the inverter, control board, or motor. Stop using the washer and complete the diagnosis before resuming use.

A power reset may temporarily clear the E315 code and allow the washer to start, but the fault will return if the underlying problem is not repaired. The error is triggered by an active hardware communication failure, so resetting without fixing the contactor, wiring, inverter, or control board will not resolve the issue. Use a reset only as a temporary step while arranging for a proper diagnosis.

Some basic checks, such as inspecting wiring connectors for looseness or corrosion between the control board and the inverter, can be done by a knowledgeable DIYer. However, diagnosing the power supply contactor and testing the frequency inverter involves working with higher voltage components and is generally safer when handled by a qualified technician. If wiring checks do not resolve the issue, professional diagnosis is recommended.

Repair costs vary depending on the failed component. Wiring or connector repairs are typically on the lower end, while replacing a frequency inverter module can range from a moderate to a higher cost depending on parts and labor. A main control board replacement tends to be among the more expensive repairs. Getting a diagnostic estimate from a technician first will help clarify the actual cost.
