Zero-crossing signal problem
The engine PCB does not detect the
zero-crossing signal for the time specified
below. At power-on: 3 s Others: 5 s

That is what the code means in the service manual. However you can try a reset by doing the following. Press 10871087 to enter maintenance mode. Once in maintenace mode press 906 then follow the steps below

1. Press the start key.
2. Select the EXECUTE using the up/down cursor keys. It is displayed in reverse.
3. Press the start key to reset partial operation control. The maintenance mode is exited, and the machine
returns to the same status as when the power switch is turned on.

If you do not feel comfortable performing this operation, or the problem persists then call a technician immediately.
