When first plugged in the door locks, displayed on panel. after a few seconds ,the drain motor runs for a a few minutes. The motor shuts off and screen goes blank. I press the on button the wash time comes up on the display. The start/pause blinks, after I press that button in about 30 sec the drain pump comes on again. The drain pump stays on and the diplay goes blank except for door locked on the display. I blew out the drain pressure hose, it had no leaks. The washer will not go into the service mode, tried several times.
