I have 2 streams 6200 that continue to stall. Both have a hard white substance inside of the main unit (once you remove the impeller you can see it on the wall). The white substance is only on the inside of the unit, its not on the propeller. I have soaked both units in vinegar, and they only run for a few wks before they stall. I have a 6201 and 6100 and 6212 that have no issues like this. Is there something specific to the 6200 units?? The units are fairly new, i have only had them for roughly 6 months.
