Repair man for the dishwasher just left. Did you know that Indiana has one of the HARDEST water systems in the world? (Gotta thank that limestone down in southern area of the state.) Our dishwasher is under 6 months old but was already having issues: the motor is laboring, dishes aren't getting clean, there's a film inside all over EVERYTHING... Here's what he told me to do:
So, to keep your dishwasher working (if you have a water softener or not), do the vinegar rinse every 2 to 3 months, USE JET-DRY, and do NOT use heated dry. Also, run your hot water for 30 seconds before starting the dishwasher--the water needs to be at LEAST 90 to attempt to dissolve the soap, but the dishwasher takes the hot water from the sink, which is at least 15 degrees less than the water heater (and that's running the hot water) and then it knocks off another 15 or more from going to the dishwasher (all those pipes absorb the heat).
He went ahead and ordered a new motor for the dishwasher, but we need to do a vinegar rinse before and after it's installed. That's filling 4 coffee mugs with white vinegar and placing them UPwards (do NOT dump the vinegar into the bottom of the dishwasher because it'll just drain out with that first rinse cycle) in each corner of the top rack. As the water runs, it will over flow the cups to keep vinegar continually running through that "load" and cleaning the gunk off of the inside of the dishwasher and out of the pipes. Yes, the cups will still be full of a mixture of vinegar and water when it's done running, but just dump them in the dishwasher THEN and drain it (for ours, that would be hitting start and then cancel).
Also, for the hot water thing, that first rinse cycle, if the water isn't the temperature it's supposed to be, it'll run longer. So, say that setting is only supposed to be 60 or 90 minutes? It's going to run for 120 or more if you don't run the hot water first.
I learned a lot of information today! Now I just have to convince everyone else we need Jet-dry and a gallon of white vinegar........ Also, FINISH All-in-1 Powerball tabs are the best product on the market. But you still need to add jet-dry even though they have jet-dry in them. That soap dissovles during the wash cycle, and you need jet-dry during the final RINSE cycle.
Okay, I'm off my lecture for now. I hope I helped some of you with your dishwashing issues too.
