This is an emergency drain issue.

Emergency drain should run for 6-10 minutes, allow the washer to run through this cycle. If this drain cycle is not allowed to complete then the washer will keep trying to run it until allowed to do so or the main control is replaced.

If the washer will complete the emergency drain, attempt to run a normal cycle to verify if everything is working normally now.

If the drain cycle does not complete after 6-10 minutes, disconnect the pressure hose from the main control and allow the drain to run for an additional 6-10 minutes.

If the emergency drain stops after 6-10 minutes & does not go back into emergency drain when attempting to start the next cycle w/ the pressure hose disconnected there is a physical fault in the system such as suds, blockage, drain system issue, etc.

If the emergency drain does not stop or immediately goes back into the drain when attempting to start a cycle with the pressure hose disconnected then the main control W11124783 has failed.
