I have a grundfos MQ45 that I rebuilt the impellers in and now it will not start. I installed a new capacitor and still nothing. The lights come and it says "pump running" but nothing is happening. It sounds like it tries to start initially and then nothing happens. I can easily rotate the pump by hand with a screwdriver.
It lights up, makes a quick "bump" over sound, then nothing. Sits for a few minutes then "alarm" lights up.
Pressure tank was at 0 psi but I filled it to 25 psi and still nothing.
Any help is appreciated.
Thanks
