Vision Washer Error Code Er:20

Er:20 means the washer terminated the spin cycle because it detected either a communication failure between the main control board and the inverter board, or a load imbalance that exceeded safe operating limits. The machine stops the spin as a protective measure to prevent mechanical or electrical damage. Checking both the laundry distribution and the wire harness are the recommended first steps.

A reset may temporarily clear the code, but it will return if the underlying issue is not resolved. If the error was caused by a one-time load imbalance, restarting with redistributed laundry may be all that is needed. If the fault is caused by a harness or board problem, the error will reappear as soon as the spin cycle is attempted again.

If the issue is only an unbalanced load, there is no repair cost. Harness repairs or connector cleaning are typically low-cost fixes, often in the range of a service call fee plus minimal parts. Inverter board replacement parts can range from roughly $50 to $200 or more depending on availability, plus labor if a technician is involved.

Start by opening the washer and redistributing the laundry evenly inside the drum, then restart the spin cycle. If the error returns with a balanced load, inspect the wire harness between the control board and the inverter for loose connections, pinched wires, or corrosion. If the harness checks out, the inverter board or main control board may need to be tested and potentially replaced.

The washer is designed to halt the spin cycle when Er:20 is triggered, which is itself a protective response. Running the machine repeatedly while ignoring a communication fault could stress the control board or inverter further. It is best to diagnose and resolve the cause before continuing normal use.
