I just watched a video of how freely the impeller should spin, and mine is definitely not like that. What would cause that?
Maybe the seal is in backwards or the impeller is rubbing.I just watched a video of how freely the impeller should spin, and mine is definitely not like that. What would cause that?
So I just took off the impeller, and noticed that the pump seal thing that looks like a spring, was on backwards. I corrected that, and the impeller seems to spin more freely now. Wired it all up and same issue. It is like a humming sound that sounds like the motor is getting power but not actually running. I am about ready to hire someone to come out and fix this, but hate to pay them to come out only to find out the motor is bad.Maybe the seal is in backwards or the impeller is rubbing.
How easily does the impeller turn by hand?
So I removed the motor from the pump housing, and also removed the impeller, and secured the motor, and it runs perfectly - the shaft spins when I turn on motor. So now it seems the motor is fine, and it has to do with my assembly of the parts. Here are some photos of the parts and seals. Do you see anything wrong? The only thing I did differently this time when replacing the motor is that last time I used magic lube on the white ceramic seal (forgot what it is called), and this time I used silicone sealant RTV because I read on TFP that is what you are supposed to use.You could try to run it with the pump housing and diffuser removed. If it won't spin you could try to give the impeller a nudge, if it runs then the capacitor might be bad. Be careful... you probably should support the motor on both sides so it won't move and be ready to turn it off. The capacitor shouldn't be bad though if it is a new motor.
Or you could also remove the seal plate and see if the motor will run by itself, again secure/support the motor.
Where does it say to use RTV?this time I used silicone sealant RTV because I read on TFP that is what you are supposed to use.
