Why does my VWR UCW-VA10101 Dishwasher leave stains or film on the glassware?

If your VWR Dishwasher leaves stains or film on glassware, the issue might stem from using phosphate-free detergent with hard water, in which case you should change the detergent. High temperatures or excessive detergent can also cause etching; try washing glassware at a lower temperature and using less detergent. Additionally, too much rinse aid could be the culprit; reduce the dosage or dilute it with water, using a mixture of one part rinse aid to one part water.
