Error comes up saying that the unit is not draining properly. So I do the below:

1. Flush out drain hose
2. Check pump (11 ohms and the impeller turns tightly)
3. Clean pump
4. Take unit through reset process
5. Get the PSB invertor error
6. Go through initial start process

And of course, I get the same drain error message at the end of the initial startup. From what I am reading it sounds like a bad board? Hoping someone can shed some light, not looking forward to dropping $400 bucks into this thing for a new board.
