Pump not starting, please help !

[look30]

Just came back from vacation and main pump won’t start. Pool is murky and have no clue how long the pump was not started. I put the system in service mode and recorded a video . Any suggestions are highly appreciated.
I will add the video shortly to this thread

Add chlorine and put the robot in the pool to mix it up.
Provide us more detail on the pump/motor including pictures of the labels.

Is it the same pump?

Does it make any noise at all?

Are you trying to start on High-Speed or Low-Speed?

Pump makes a lot of noise, maybe motor is dying.

Hi Guys, recently the pump is making a lot of noise , I think is the motor but now 100% sure as this is a very old pump too. Any suggestions for a replacement, either motor only or the whole pump? Please help ! I have a friend who is certified electrician so installation should be easy.

Type CXCP has 3 capacitors.

There is a run capacitor for high speed.

There is a start capacitor and a run capacitor for low speed.

The top hump contains a dual run capacitor.

Check the capacitors, measure capacitance and replace if bad.

 

[JamesW]

Probably a bad capacitor.

Try replacing the capacitor.

Pump is Pentair WFDS-8 , usually should start at high speed. Ill try to see if low speed works.

When was the pump installed?

Has the motor been replaced?

If yes, when and why?

Why is the bond wire not connected to the bond lug?

The capacitor is probably bad.

I would replace the capacitor.

You can access the shaft from the back by "carefully" twisting the back shaft access cover to see if the shaft turns easily.

So first of all you guys are AMAZING!.

With the controller in service mode I can start the pump and low speed , I got rid of the air and looks to work fine no strange noises so I went a step further disabled the low speed and high speed kicked in and I should ahve left it at that for today but I tried to see if that will work again and it didn't , once the pump is set to low speed it will start but doesn't revert to high speed any more so with my very little knowledge of electric motors I would assume that is the capacitor like you guys pointed out. If you can help with the correct capacitor spec I will start looking for a replacement ASAP.

The Pump was replaced 2 years ago by professional company under home warranty, I have no clue why that wire is not connected... Took them 3 months to come and replace the pump and I have no documentation for that as it was performed under the warranty and they didn't gave me any paperwork.

I went a step further disabled the low speed and high speed kicked in

The controller might be misconfigured and sending power to both windings at the same time or it might be just a bad capacitor.

Remove the capacitor and check the specs and a local pool store or electric motor repair shop should have a suitable replacement.

 

[JamesW]

Pentair can tell you the correct capacitor, but the specs are printed on the capacitor, so just take it out and bring it to the store for an exact replacement.

Pump Capacitors - Further Reading

Be careful when handling a capacitor. It can hold a voltage charge for a long time and you can be shocked by it. To drain all the power out of a capacitor you can touch both prongs together with the shaft of an insulated screwdriver. You may get a spark or pop from the current outflow.

I’ll get on it now and remove the capacitor and head to Leslie’s see if they have it in stock if Amazon doesn’t sell it

 

[JamesW]

If the windings are good, a capacitor should discharge through the windings, so there should almost never be a charge, but the safety warning is still valid because there can be times when a capacitor can store a dangerous charge.

If you find that a capacitor is actually charged, the windings are probably bad.

Inyo Pools will also likely know the correct capacitor.

So quick update, found a capacitor with same spec and now everything works fine. Thanks again for your support!
