Maytag Washer Error Code E27

E27 means the main control board sent a command to the frequency inverter (the motor control unit) and received no response within 5 seconds. This communication timeout causes the washer to stop running. The fault points to a configuration mismatch, a wiring problem, or a failed electronic component in the motor control circuit.

No, you should not attempt to bypass or continue running the washer while E27 is active. The error exists because the main board cannot confirm the motor control unit is responding correctly, and running the motor under those conditions could cause further component damage. Address the fault before resuming normal use.

A reset may temporarily clear the code, but if the underlying cause is not corrected the error will return as soon as the washer attempts to start and the communication timeout occurs again. A reset is useful for confirming whether the fault is intermittent, but it is not a repair. The configuration settings, wiring connections, and component health all need to be evaluated to resolve the fault permanently.

Some causes of E27 can be addressed without professional help, particularly if the issue is an incorrect configuration setting or a loose harness connector. Checking that the correct washer type and power supply voltage have been selected is the recommended first step. However, if the fault points to a failed frequency inverter or main control board, replacement of those components typically requires comfort with disassembly and working around high-voltage electronics.

Repair costs vary depending on which component is at fault. If the fix is a configuration adjustment or a reseated connector, there may be no parts cost at all, though a service call fee could apply if a technician is involved. Replacing a frequency inverter typically runs anywhere from $150 to $400 in parts and labor, while a main control board replacement can range from $200 to $500 or more depending on the model and labor rates in your area.
