If there is too much water or foam in the machine the overflow ow contact
on the pressure switch is closed. If the valves are open they are
automatically closes and the drain pump is switched on for at least 30
seconds. If overflow ow occurs 5 times the error code is displayed and the
pump drains the machine. To unlock the door press PAUSE/CANCEL.
Check the drain hose and make sure it is not plugged or kinked.
Unplug washer or disconnect power.
Check wire harness connections to the drain pump, pressure switch,
water inlet value, and Central Control Unit (CCU).
Check/clean drain pump filter of foreign objects.
Check for drain pump failure.
Check the inlet valve for proper shut off.
Check the pressure switch for proper operation.
if you cant do these tests you will need to call for service unfortunately, hope this helps, thanks, Bryan
