Mine was also almost imposable to service due to the rat at the factory who had to deliberately wrap the wiring, and a water line around the housing. I moved all that out of the way, but decided to take it out completely and use the blue hose filters available almost anywhere. Probable cheaper in the long run anyway.
Retired and loving it.
Got a new 2014 Grayhawk 31DS
Hoping to get away from the IL winters
