    Do you see any streak staining from a source or is it in you water supply?

    I’m pretty sure it came from non stainless soap pads which I found that are not supposed to be used at all.

    Found particles on the door magnets and on the switch lever magnets. I don’t believe it is a hard water issue.

    The biggest thing to do is remove all sources of iron. There are acid base cleaners that will remove the stains, but they should go away over time if the sources are removed with normal dish machine cleaning. ie; mineral cleaning. There are a lot of different brands sold for the purpose from food service chemical suppliers and restaurant food suppliers. Check closely for screws and bolts that may have been replaced with non-stainless ones.

    BTW, what model machine is this?

    Has the Grunfos recirculating pump eve been replaced? If so, make sure that it has a bronze housing, not iron like is common in heating systems..

    Hey Drewus, Have you isolated the source?

    Sorry I haven’t got back to you sooner fixbear. The problem turned out to be particles from the soap pads they were using. I do not use recirc pumps on any of our machines here. Thanks for the help.
