Thank you for posting your question here on Fixya.com.

It could be the pump is bound up but it is more likely the motor is failing. It may be a small part such as the capacitor or the starting switch, but could also be more severe such as the winding itself. You will also want to examine the shaft where it passes thru the pump and motor and look for signs of rust from a pump seal leak.

If you are not familiar with testing these parts your best bet would be a local electric motor repair shop to see if the motor can be repaired or if it would need to be replaced. They should also be able to ensure there is no pump damage.

If this answer does not fix your problem, please comment with additional details prior to rating the answer. Positive feedback is appreciated once your problem is solved!

Having problem with polaris 380 not moving. just replaced back-up valve and having a different problem. there are three small devise on hose that are spraying water.


If the wheels are spinning independently you have broken drive belts. The hose swivels are leaking also which could lower the pressure to the head.
