My LXIH 30 will not fill on initial start up. Pump down finishes then solenoid fires for a fraction of a second then shuts and sump element comes on as if sump is full. Unit has been working fine for many months. Cleaned probes, swapped out relay board and control boards with some from another working unit, no help. Machine cycles fine if you initiate then after pump down fill with hose. cycles fine until shut down, then wont refill upon start up

hi there have you checked that the drain pump is pumping out the water fast ehough, sounds like you may have a blockage problem and the programe is timeing out ie. not draining within the specified time, for example 3 mins

I can't imagine a bad relay board would blow a fuse. The relay board would need to make a bad connection to ground to blow a fuse -- I don't see it.
If you could supply me with the ML#, I'll take a look at the wiring diagram and give you an educated answer.
Not that I recall clearly which fuse is for the drain solenoid, but the two sound related. If a drain valve is obstructed by debris, it will heat up the coil and short it out. I don't know the spec'd ohms, but I would suspect at least 50. I'd check it.

Frank,does the sump probe (the one underneath the screen) look good?It should have at least one quarter inch of metal.I have seen these break and its hard to tell but the info your describing sounds like that probe is bad or the control board.I'm a hobart tech and can help you troubleshoot,let me know----Tony
