i did change the water filter, clean the condenser and use cleaner on the water circuit when i first did this one.
so im pretty sure thee only problems left are the water valve, and this evap plates you mentioned. I dont see a detailed discussion about them in the manual.
i mention the float position because that is where i got it to work best for time and size when they first asked me to resurrect this dinosaur last year.
and that point is maybe almost half way along the slide.
could it have had the evaporator problem all along i guess?
ill climb up there and take a look at the end of freeze tommorrow, and im gonna go ahead and get a fill valve for it just to be sure.
but with the evap plates, is that repairable? or do you have to replace the evaporator?
