With my Autocover came a Little Giant Pool Cover Pump http://www.lg-outdoor.com/p/apcp-1700?pp=12
Model number APCP-1700, CAT 577301, made by Franklin Electric, Okalahoma City OK. 73112-2935
It had been behaving erratically, turning off during pumping, not turning on when water level raised etc. Yesterday I emailed Franklin Electric, and to my surprise a person knowledgeable in their repair called me back a few hours later. He explained to me what could be happening. First suggestion was that the float had a hole/crack in it, and he gave me the part number to do a warranty claim. I asked about pollen gumming up the works of the switch etc., he advised it could be possible that the magnet the float raises could be dirty, and just need a cleaning. Finally he suggested one other thing to look at, which is a small hole that if blocked could cause "air lock", which didn't fit my description of the problem (he implied it would not work much at all if clogged), but i could check it while i had it taken apart.
First i removed the small round access plate from the bottom of the pump housing. Second i took out the 5 philips head screws holding the blue housing on. Third i removed the pump float (it justs kind of clips in place).
Float had no water in it, and looked fine, allthough dirty. Both sides of the magent looked fine too.
Next i looked for the hole he was talking about, it's dead center of this picture and clogged.
It was also clogged from the back side so i had to remove 4 more screws i think to remove the cover of the impeller to get to the backside of the hole.
When i slide the cover off, it dislodged the debris, and i had my hole back.
Took about 10 mins., and it works perfect now.
Guess i'll have to clean it ever so often, or blow off my cover in the off season more often, so that water and debris don't mix and cause this issue again.
