switch is operating properly. Check the
pressure switch harness.

If the controller was installed in a different
size machine before being installed in this
machine, a problem can occur. If someone has
been doing repairs on the washer, check for
the correct size drive. It can also be caused by
pressure switch harness. Check to ensure the
correct harness in installed. The control can be
reset by holding program button on controller
during startup (soft reset). Check orange wire
at Molex connector on controller coming from
pressure switch or replace pressure switch
harness.
