My Sedra 3500 pump stopped working on my ASM 1-GX, I've taken it apart and all looks o. k. it's ~ 1 yr old...could it be the impellar (looks o.k. any other way to check it) any help would be much appreciated, Thanks
No rust at the back end at the cord insertion looks new. The needle wheel moves freely on shaft out of the pump body and does turn inside the body with tension against it. appreciate the help these pumps are expensive!!
