I worked at one place where they had a dishwasher. They had stopped using it by the time I got there. But if they had kept using it I would have gotten a clean glass and put it in to see how clean it came out. I think after a while with only one tan

Thanks for the reply. Yes we currently have an Ionagraph setup at the bottom of the wash where we take the first board out for that day and check it for contamination. Im just wanting to get an idea if any jets are blocked and that the temperature

We are using a Trek board washing system with 2 deionizer tanks hooked up to the 2 final rinse tanks and the first tank is directly connected with the city water. We are having problems with a vendor board on some tranformer/chokes. The part manufact
