My cups and glasses are coming out spotty, cloudy and filmy. What's wrong?

For spotting only, try using the heated drying cycle. If that doesn't help, try using a rinse-aid product. 

For cloudiness or filminess, there are several possible causes: 

Excessive detergent usage: Etching, or cloudiness, is glass corrosion. It is often caused by using too much detergent. A rainbow hue is the first sign of etching. Cut in half the amount of detergent used.

There could be a water flow restriction. Call Hill Country Appliance Repair we can help.

You may have hard water. You can purchase water hardness testing kits at home improvement stores to determine if a water softener is needed for your water supply.
