motor problems

I recently replaced the pool pump motor because the bearings were shot on the old motor (horrible whining sound). I had a spare motor on hand (same exact make and model) so I swapped it in for the old motor. When I powered back up, the motor wouldn’t start and there was nothing but an...

Part 1: pool motor sounded weak and pump not moving water properly. On the assumption that we had a dying motor, we bought a new one, (exact replacement Century (A.O. Smith) 1.0 HP Up Rate Motor, Round Flange 56J Frame, Single Speed - Model UST1102 Voltage 115/230, Max Amps 115V = 15.0 230V =...

Hi All, After going through the messy and laborous process of replacing the two propulsion/drive motor brushes on my Dolphin M400 it now looks like I'll have to repeat the process again on the impeller motor. Well, I started investigating to see if there were any robots on the market with...

My pool motor recently started screeching. Hopefully you can listen to it with the short 10-second video in the link below. I am thinking the bearings are going out (?), but want to know if there is something I can do to repair or fix vs. buying a new motor. I believe the motor is only a few...

I have a 12 year old pool with the original pump. The pump has started to turn off and then go back on. It has happened three times (that I am aware of). When it turned off today, I went over and felt the motor and it was quite hot. About 10 minutes later, it turned back on. In a search for "how...

Hi, TFP! My motor changed its pitch this week. It is a much higher tone than it used to be. Also, it appears that only one of three jets are flowing. I know it's hard to diagnose in a forum, but I thought I'd give it a shot before going to the dreaded pool store. TIA

Hi all, I woke up to the motor making a noise. Almost a screeching sound. It’s done this once or twice, but only recently. Turning it on/off seemed to resolve the problem. The noise started upon restart, but then seemed to go away shortly after. If I didn’t know any better, it’s almost like it...

Just installed a new motor to my pump, and when I fired it up, the switch was turned from 230v to 115v. It was making a bit of noise so I killed it immediately. After setting it to the correct voltage, it now will not come on. What’s my next step here?

Hi everyone.... My 14 month old pool pump (see title for type) would no longer turn on when we returned from vacation this weekend. I have spent several hours reading through websites, watching videos, etc... However, I couldn't seem to find a post that dealt with pumps just not turning on at...

I have a Dolphin DX5-S that would start and work awhile and then shut off, though now it doesn't move. I have gone through and tested all electrical and everything is spot on all the way to the motor assembly. After taking apart there is no water damage inside the motor compartment, cleaned...
