Perform Pressure Relief Procedure, page 13.

2.Turn the ON/OFF switch OFF wait 30 seconds and then turn power back ON again (this ensures sprayer is in normal run mode).

Turn the ON/OFF switch OFF, remove the control cover then turn power back ON. Observe the status light. Blinking LED total count equals the error code (for example: two blinks equals CODE 02).Press display button to restart code messages.
