What have you tried so far?

Tried running the machine it locks the door, tries to drain the water. Then it runs the motor for about 6 sec’s then shuts down, then will not unlock the door. You have to on plug the machine. Is there any diagnostics sheet on this unit. Is it possible to short out the control board because a flood problem.

Here is the test for the main control. Run through the diagnostics and see if there are any error codes. This should tell you if thier are any issues with the board. Matt Ace technician
DIAGNOSTIC LED – MAIN CONTROL
A troubleshooting tool has been implemented
onto the main control board—a diagnostic LED.
LED ON – The Control is detecting correct incoming
line voltage and the processor is functioning.
LED OFF – Control malfunction. Perform TEST #1:
Main Control, page 12, to verify main control
functionality.

SERVICE DIAGNOSTIC TEST MODES
These tests allow factory or service personnel
to test and verify all inputs to the main control
board. You may want to do a quick and overall
checkup of the washer with these tests before
going to specific troubleshooting tests.
