I had a persistent clog in my 7600 that would not go away. So, I loaded cleaning fluid into all the positions, did an "initial fill," and let it sit for more than 2 weeks. It appears to have worked. I re-loaded UT7 and the nozzles are all perfect again - not a single cleaning cycle was needed. Hopefully this will last. If not, it's time for new dampers. At any rate, the point is that leaving the cleaning fluid loaded for a long time seems to be able to dissolve through persistent clogs - as MIS had suggested.
