Dishwasher Repair - Soft Water | Dishwasher Repair Meridian

Soft water, as used in dishwashers, is virtually mineral free.  Total dissolved solids are usually low, in the range of 100 to 200 ppm.  Water is considered soft when the grain hardness does not exceed 4 grains/gal.
In naturally soft water the temporary hardness, or bicarbonate content, is the important factor affecting the Ph.  Solutions of bicarbonate, when heated to a high temperature, undergo a chemical reaction to form a carbonate.  In the presence of hardness, the carbonate with the calcium and magnesium, precipitates out of solution as scale.  In soft water this precipitation does not take place, and the carbonate stays in the solution.  Carbonate is much more alkaline than bicarbonate, causing the alkalinity of the final rinse water in a dishwasher to increase.  The carbonate and bicarbonate content of water is part of the total dissolved solids.  Most naturally soft water will have some calcium and magnesium dissolved in it, even though the amount may be small.

Many appliance repairs in Boise, Meridian, and Eagle areas of Idaho have to do with white scaling found on glassware and dishes.  In the majority of these dishwasher calls the problem lies with the hard water that is being used to clean the dishes.  If you suspect you may have hard water the best cure would be to invest in a good water softener.  This will help your dishwasher clean better and it will minimize the white scale you see on your dishes.
