Soap dish cover fails to open 1 of every 2 washes.

Any ideas fix?

Thanks

Could be any number of things. First thing I'd do would be to look for
loose connections in the wiring harness that feeds power to the door's
wax motor actuator. Second would be to check the motor itself. Your
washer may have a self-test cycle which allows you to test each switch
and actuator -- the big problem is finding how to enter that hidden
mode. Sometimes you will find a service sheet with such information
hidden inside the kick plate or hung underneath the washer but that
can't be depended upon.

Of course when working on such things it is best to kill all power to
the equipment when poking around in the wiring. If the whole thing is
too confusing, then calling out a service tech may be best overall.
