Maytag Washer Error Code E320

E320 indicates that the washer detected an instantaneous power failure lasting between 15 and 100 milliseconds. This is a very brief interruption in the power supply that the control board registered as a fault. It points to a problem in the power circuit rather than a component inside the washer itself. Checking all connections in the power circuit is the recommended first diagnostic step.

A brief power interruption in itself is not immediately dangerous, but the underlying cause could be. Loose or arcing electrical connections, a damaged power cord, or an overloaded circuit all present potential fire or shock hazards if left unaddressed. It is important to inspect the power circuit promptly and not ignore this code, especially if it appears repeatedly.

If the fix is simply tightening a connection or replacing the power cord, costs can range from around 10 to 50 dollars for parts, with minimal labor. If the circuit breaker needs replacement, expect 50 to 150 dollars including an electrician's visit. In the less common scenario where the main control board is at fault, parts and labor combined can range from 200 to 400 dollars or more depending on the model and service rates in your area.

Start by unplugging the washer and inspecting the power cord, wall outlet, and all accessible wiring connections for looseness, corrosion, or damage. Make sure the washer is plugged directly into a grounded outlet and not sharing a circuit with other large appliances. If connections look good, test the outlet voltage under load and inspect the circuit breaker. If the problem persists after addressing these external factors, a technician should evaluate the internal wiring harness and control board.

A reset may temporarily clear the error code from the display, but it will not fix the root cause. If the power circuit issue remains, the E320 code is likely to return during the next wash cycle, especially during high-draw phases like the motor spin-up. Address the underlying power connection problem before relying on a reset.
