Midea Washer Error Code E50/E55

E50 and E55 on a Midea washer indicate that the motor speed signal has been lost and the unit has stopped operation as a result. The control system can no longer confirm how fast the drum motor is spinning. This fault typically points to a wiring connection problem, a failed inverter module, or a motor fault. The washer will not resume operation until the underlying cause is resolved.

No, you should not attempt to continue using the washer while this error is active. The machine has already stopped itself because it cannot control or monitor motor speed, which could lead to mechanical damage if operation were somehow forced to continue. Resolve the fault before running any wash cycles.

A power cycle reset may temporarily clear the error code and allow the washer to attempt another cycle, but the fault will return if the underlying cause has not been addressed. Repeatedly resetting without diagnosing the root cause can mask a worsening problem. A permanent resolution requires identifying and correcting the specific wiring, inverter module, or motor fault that triggered the code.

A knowledgeable DIYer can begin by checking and reseating the wiring connections between the motor and the inverter module, which costs nothing and resolves many cases. If the connections are secure, diagnosing and replacing the inverter module or motor requires more technical skill, including the ability to safely work around high-voltage components. If you are not comfortable working inside the washer's cabinet, a qualified technician should handle the repair.

Repair costs depend on the failed component. If the issue is simply loose wiring, there may be no parts cost, though a service call will still carry a labor charge. Inverter module replacement typically ranges from around $80 to $250 or more depending on the part and labor rates in your area. Motor replacement is generally the most expensive repair, often ranging from $150 to $400 or higher including labor.
