Thank you, I'll give that a whirl this weekend.Originally Posted by GingerJohn
You will know if it is spinning with an air lock, it sounds like it is trying to pump gravel.
Drain loop, take pump apart, check for any fouling or visible damage. Then try running the pump in a test loop (beware, they are powerful beasts - I soaked half my apartment doing that once).
If that fails then it is sounding like there is a problem with either the control board or a coil has burnt out. There are some repair options if you have decent soldering skills.
I checked the molex,looked fine but I'll consider all my options. Thanks!Originally Posted by Big Elf
I forgot that it could also be a problem with the molex plug giving an intermittent connection.
I had this problem when I was running 2 pumps separately and the second one often wouldn't start up. In my case it was due to plasticiser in the CPU block that was gradually building up.
Looks like my pcb is bad..Originally Posted by GingerJohn
