Question about Pentair 1.0 Hp Whisperflo Pump

1 Answer

My Whisperflo was making a buzzing noise while pumping. I turned it off to clean the strainers and now when I turn it on it makes a loud buzzing noise and the motor does not spin. The impeller moves freely when I spin it manually. Thanks for the help.

It's a bad start/run capacitor. It's under the hump on top of the motor. DO NOT touch the terminals with your bare hands in case the capacitor is charged. You can replace it with an exact match.

Samsung dishwasher makes a loud buzzing sound when the water is filling. It pulses a couple times to start then is constant. It pulses again right before the wash cycle. Comes from the bottom left.


This is common. The noise is coming from the water pump. If it bothers you, you can try UNPLUGGING the washer or turn off the Circuit breaker first. Then you can remove the bottom kickplate on the front of the washer and clean around the pump. If there is a water filter scree, clean it out. Make sure there is nothing rubbing against the pump which could cause a buzz. Tighten all fittings and screws to eliminate vibration noise.

When I turn on the self cleaning oven, it makes a loud buzzing noise. Is this normal? If not, what needs to be fixed and how do I do it?


The buzzing sound comes from the relays located on the control board. Remember, the oven gets very hot during self clean, so the control works at full speed to get all the elements working.

Sounds like you've got a thread jam going on in the bobbin case area. Good cleaning and a new needle will probably fix it. See: https://answers.yahoo.com/question/index?qid=20091202121550AAHxN8y

Whirlpool duet sport makes very loud noises when it expells water through all cycles


How old is the unit?

I would venture to say that your drain pump is failing. Some will make a more louder than usual noise near the end of life. Have you checked the pump strainer yet? If it's clear, go ahead and replace the pump. It's a very easy DIY fix.


btw: remove the lower access panel to the washer. The strainer is located in the pump and will twist out w/a few turns. put something down on the floor (pan, towel, ect) before you remove the strainer for it will empty out whatever is left in the lower tub.

Pump motor makes loud noise when pump comes on


If this is a high pitched sound, then this sounds like you have bearings that are starting to go out.  There is not much that you can do to prevent eventual failure.
The only other option that I see is that there is something causing friction inside the pump between the impeller and diffuser.
