I have two 6100s on a 7095 multicontroller. The alarm went off yesterday and when I consulted my manual and this site I figured it was time to clean them. There was quite a bit of calcium deposits on the drive shaft so I soaked them in vinegar overnight, this morning they were clean. First question: besides the rotor is there anything else that is removable and needs to be cleaned (didn't look like it and didn't want to force anything). So I reassembled everything and the right stream does not work. I opened up both and switched the drive shafts and rotors, same result - the right side does not work. I've also noticed that the right side transformer and driver box is hot to the touch while the left side is cool. Question 2 - What is the problem and where do I start to trouble shoot this? Thanks in advance.
