Been fighting this dishwasher's poor performance for a while. Ready to sit it on the curb. Here is what I think I know using the water/service test:
Neither of the top two spray arms rotate or move at all
Both dispensers work
Inlet valve filter is not clogged
Overflow float never trips
Water reaches the just covers the post that the heater element mounts to
126 seconds to fill
Water temp 120
Check ball rolls back towards the rear on the dishwasher
Water in bottom of dishwasher after all cycles looks dirty
After the drain cycle a little amount of water flows back into the bottom of the dishwasher
Dishes have some whitish grit left on them
Air gap is new, as the old one looked pretty dirty to me
I use the normal cycle with no other options
Drying vent on door was clogged with "stuff" but now is replaced and working.
Not looking to replace it unless I have to.
