Dishwasher leaves behind gritty residue i am not sure of what to try...


We have a Kitchen Aid dishwasher, 10 years old, never any problems until 2 weeks ago, then we started noticing a gritty subtance on the dishes and glassware. We're on well service, psi 40-60. water hardness is 6 grains. small trace of sulphur, and we have a Mermaid sulphur system, then a complete house carbon filter, and finally a Culligan water softner. Checked everything, Water temp. at kitchen was 120, all cycles on dishwasher were operating. Called in repair service, he says something is breaking down in the dishwasher, best to buy a new one. That'll be $150.00. Thank you very much. Tried the white vinegar, no change. Next bought 2 bottles of Dishwaser Magic. Slight improvement. Next bought 1 bottle of Finish Dishwasher Cleaner. Bingo. The thing is like brand new. even the trays slide in/out much easier. None of the dishsoaps contain phosphate, which is what helps disolve the minerals in the water. I'm not sure what the gritty stuff is, maybe the buildup over time, and it just keeps getting redistributed through the wash and rinse cycles, and finally baked on in the dry cycle. According to a tech with many years repairing appliances, the majority of their calls are for dishwasher poor performance, all because they removed the one compound that's been cleaning our dishes for years, Phosphate. We've always used Cascade gel soap. best on the market today, Finish Quantum. We tried it and dishes look terrific. It's a small tablet that fits in the soap dispenser. All Mfg's. today recommend that you run a dishwasher cleaner once a year, Experienced tech recommends every 3 months maybe more if you're on hard water. Good luck.

We get a gritty / sandy residue. what can I do?


The cause may not be your dishwasher.
Especially hard water may leave the residue. If you don't have that problem when you hand-wash, then check your pipes. Homes more than 40 years old may have galvanized pipes that eventually rust on the inside. The grit could be grains of rust from the pipes. If you do have galvanized pipes (rather than copper) then you may need to replace them. You could put in a filter as a temporary work-around, but that will eventually clog with the gritty material.

Although I previously posted with the same problem of a film on the dishes after cleaning, I did find a section in the owner's manual which solved my problem. Lift up the rinse aid cap on the inside door - the factory setting is on "4". The rinse aid works in conjunction with your local water, which has variations in it's hardness or softness. When your dishes are streaky, lower the rinse aid setting to 1 or 2. If your dishes are spotted, raise the rinse aid setting higher.
