Noisy Pump

[cheapjack]

My pump (Jandy 2.7HP Variable Speed Model# VSSHP270AUT) has started making a cracking noise. The noise is coming from the motor side and NOT the pump side. So it can't be the impeller.

What do you think it is?
Is it dying?
Can it be fixed/redeemed?
Can I DIY or do I need to take it to a shop?

Thank you for your advice.

Sounds as if something is tapping the inside of the motor casing as it spins around. I've not heard a bearing make that sound, but maybe one of our other members will confirm. Anything odd happen recently? Motor run dry or anything that may have caused warping? How old is this pump/motor? That could determine if it's even worth a repair, or just replacing the motor.

Could be the fan rubbing the casing, you will probably have to open it up.

With the pump running place your hand on it to see if the noise lessens or stops. Look for the bond wire and see if it is vibrating against the motor somewhere.

Thanks for your response.
- No dry running
- Pump was installed in 2013. What is the life of these things?

It varies. I've seen some with problems as early as 3 and others moving water at age 15. If I had to throw an average out there, it would be 7-9 year range. Anything past that and you're doing well IMO. Going on 9 years you've done quite well if that's all original.

Oooh... there goes another $1500 in the money pit! I guess I'll keep it running till it dies and then replace it. Thanks for your input.

It could be the motor bearings. A good motor shop can replace them. What are you using to control the motor?

If that's all it is, I would be all for bearing replacement. I use a wireless Aqualink Pool Automation System to control the motor.

If you are willing to do it, you can take the pump apart. Remove the bolts holding it together and turn the motor on. If the noise stays with the motor you have found the issue. You may actually find that there is something that is stuck in the impeller and the noise is being transfered to the motor.

It would be best to find a motor shop willing to work on it before you do so as many won't work on a VSP motor for some reason. If you are not familiar with this type of work it is best to hire it out. You will be working with high-voltage (can be dangerous if great care is not taken), communication cables (can easily short the motor or Jandy control), seals, gaskets, and fasteners that can easily damage the pump if not done correctly.
