Midea Washer Error Code E64

E64 indicates that the communication signal between the main PCB and the inverter PCB is abnormal. The inverter PCB controls power delivery to the drive motor, and both boards must communicate reliably for the washer to operate. When this signal is disrupted or lost, the washer stops all operation and displays E64 to alert the user. The fault can stem from loose wiring, a damaged harness, corroded connectors, or a failed board.

No. The washer automatically stops operation when E64 is detected, so it will not allow a cycle to run. Attempting to force operation with a known communication fault between control boards could risk further damage to the motor or electronics. The fault should be diagnosed and resolved before returning the unit to regular use.

Repair costs vary depending on the cause. If the issue is simply a loose connector, there may be no parts cost at all, though a service call from a technician could run anywhere from $75 to $150 or more. If the inverter PCB needs replacement, parts and labor combined could range from $150 to $350 or higher depending on your location and the specific model. Main PCB replacement tends to fall in a similar price range.

In some cases, yes. Start by unplugging the washer and inspecting the wiring harness and connectors between the main PCB and inverter PCB. If a connector is loose, reseating it firmly may resolve the error. If wiring is damaged or a board has failed, those repairs involve working inside the machine and may be better handled by a qualified technician.

A reset, such as unplugging the washer for a few minutes and restarting it, may temporarily clear the error if the fault was caused by a transient signal glitch. However, if the underlying cause is a loose connector, damaged wire, or failed component, the E64 code will return once the washer attempts to operate again. A reset alone is not a fix.
