Error code 8C

Hello,
After checking the wire connections, I would order the Mems PBA and main control board and start with the MEMS board as it will be less expensive. Then return the board you do not need.
1.Check the wire connections.
2. Replace the Mems PBA. The MEMS sensor is basically a vibration sensor to control board that the machine is experiencing and out-of balance condition.
3. Main PBA wire connection Check or PBA’s silver nano part
malfunction. Replace if necessary
The reference to the PBA’s silver nano part malfunction, this information is in reference to the main control board.
