hawkella Posted September 3, 2013 Report Share Posted September 3, 2013 I have a white water spa pump. It is the circulation pump and also high speed pump. Right now high speed works but circulation stage hums and will not start. There are two capacitors I'm thinking start and run. Why would it run at high speed and not start at low? Could it be the capacitors as the voltage is fine and its obviously not seized/starved for water? Thanks Quote Link to comment Share on other sites More sharing options...
n1oty Posted September 3, 2013 Report Share Posted September 3, 2013 The windings in the motor (start winding and run winding) are separate, so you may have an issue with the low speed run winding. I'd still do a capacitance check on the caps though. A weak cap can also exhibit this seemingly strange behavior. John Quote Link to comment Share on other sites More sharing options...
hawkella Posted September 3, 2013 Author Report Share Posted September 3, 2013 Thanks for the reply. Its an intermittent problem - would that indicate capacitor or windings? (Seems to be gettting worse though) Quote Link to comment Share on other sites More sharing options...
hawkella Posted September 3, 2013 Author Report Share Posted September 3, 2013 One more thing - when I switch the power cables to the pump I still get the flo error even though the low speed signal is pumping st high speed Quote Link to comment Share on other sites More sharing options...
