I have a dishwasher issue as well. I think the water doesn't get jetted up the arms as much as it should (If I interrupt mid-cycle, msot top dishes are only steamed, not soaked). So I want to do an attempt at clearing the residues. I can hear the dishwasher pump still works, or it's the arms, but there's a lot of noise, just not the splashing I'd usually hear against the door.
Used the instructions on the CLR bottle. Normal wash - when it gets to the actual wash cycle (past the first rinse) then add in a half cup of CLR and let it finish the cycle. Then run another full cycle using cold water.
Our arms were full of lime - I could not get all of it out but had to do a LOT of poking and prodding in the holes.
All I can do now if keep clearing the holes and call the softener repairman tomorrow.
I dont know if those instructions work every time.
My dishwasher sort of cause into a confused seizure when you interrupt it. It doesn't really resume, it seems to flush its water tank and start over with a fresh batch.
You and me, buddy, will be cleaning our dishwashers this week. May I suggest you take OUT the arms, lay them in a shallow bucket large enough to hold the arms, then soak in CLR to let it sit for 24h or something.
While I would not mind soaking it a lot longer to see if I can to get the lime out - I am not sure of the long term effect of old style CLR on plastic...
