I have a Kenmore Automatic Dishwasher. The glasses and dishes look clean after a wash, but if you get water into a glass, you can still see some foam traces (suds) on the top of the water. More like a light sud from a beer pour. I've tried liquid and solid type of soaps but the problem remains. What is going on ? And how can I prevent this? If the glasses are rinsed again individually under the tap, the suds are not present.
Thanks.
