Does it make sense to repair my pool motor?

When it comes to a failed pool pump motor, the pool owner is faced with that eternal question, “repair or replace?”

Blog Image - Warranty (200 x 200)The first thing to check is if it’s still under warranty.  For a pump that still has the original motor, you would contact the manufacturer of the entire pump.  If you have already replaced the motor before, you would contact the manufacturer of the motor.  As most pump and motor warranties are only 1 year, you might be out of luck but it’s worth double checking the purchase date.

Assuming you are out of warranty, you have a decision to make.  A replacement motor is generally going to cost you in the neighborhood of $150 – $300 depending on the horsepower.  Add another $15 – $30 for the absolutely necessary, non-negotiable new shaft seal.  Can you repair it instead for less?  Probably.  Is it worth it?  Maybe.

Blog Image - Tools (200 x 200)Here’s the deal with repairing pool motors.  You have to figure out the actual problem first.  Is it the capacitor, the bearings, an electrical short?  If you’re mechanical and handy and know your way around a pool pump, then it could be fairly easy for you to diagnose the issue and even repair it yourself.

If you’re none of the above, you will need to have a tech come look at it or take it to a motor shop – and that alone could cost you before any parts are even replaced.  You also need to find a repair person that you trust so you can be confident the real issue is being addressed.  From what we hear from pool owners across the country, that’s a rare find.

Blog Image - Money Scales (200 x 200)Another thing to weigh out is the age of the motor and if it’s worth investing any money into it.  Age is relative to where you are located.  A pump running 365 days a year in warmer climes is going to be “older” than the same pump with the same installation date in a colder region where pools are closed most of the year.  So if it’s over 2 – 3 years old in the Sun Belt or 5 – 6 years old up north, most likely it will not pay to repair it.  Many pool pump motors last less than 5 years; the last thing you want to do is put $100 worth of repairs into a motor that was destined to die in 6 months anyway.  Plus none of your replacement parts will carry a warranty whereas a complete new motor will.

Blog Image - Motor (200 x 200)Especially with online motor prices being more competitive these days (remember, free shipping from Inyo Pools!), it is definitely worth a few searches and a few phone calls to compare prices for replacement vs. repair.  I’ve heard of pool owners getting motor repair quotes locally that are $100 more than the cost of a new motor and seal.  I’ve also heard of handy DIYers who buy a few bearings on the cheap, replace them, and get up and running again.  It really is a case-by-case scenario as there are so many variables affecting each individual pump.

The bottom line – I believe in general you will get more value and longevity out of replacing the complete motor.  Motor replacement also presents you with the opportunity to upgrade to a more energy efficient system – perhaps a lower horsepower if your pump is over-sized as so many are, or a dual speed or variable speed.  In many cases, you can easily recoup your motor expense through energy savings.  To get an idea of variable speed pump savings, try Pentair’s Savings Calculator.  This calculator is based on their IntelliFlo pump but will give you a general idea of energy efficiency’s  impact on your wallet.

    I live in Virginia and have an outside pool pump motor that is 16 years old. It runs, but I’ve had to kickstart it the last three seasons after winter as the shaft was initially hard to turn until I worked it loose with a wrench. Should I try replacing the shaft seals before I go with a new pump?

    1. Matthew Simmons Avatar

      It sounds like you need to replace the bearings in the motor if you have to tug on it with a wrench. Replacing the shaft seal at this point is putting a bandaid on an axe wound. I would replace the bearings (and any other necessary parts) or the motor, to go with a set of new seals.

    Hi , my pool pump stops turning on , when i remove the cap on impeller shaft , its hard to turn and can only turn using a wrench couple of times and then when it feels that it turns little easy , the. It will turn on upon switching the electricity.
    Can you please suggest i live in tampa, fl and its been just 2 years that i replaced which costed me around 400$. Shall i keep relacing motors in fl every 2 years.?

      If the motor shaft is hard to turn, then it is likely the bearings. These are replaceable of course. My concern with your situation is that you keep replacing these motors every two years. This type of cycle leads me to believe there is something amiss in the pump or in the area around the pump. Most of the times I have seen bad bearings, the issue is with improper shaft seals. Either the seal was installed incorrectly, or it wasn’t replaced when the new motor was installed. Either of those will cause a leak into the motor, rusting bearings and anything else the water gets exposed to. If the shaft seal isn’t the problem, then I would look to outside sources of water, like spray from sprinkler heads, rain runoff or splashing from the pool itself. The motor can be covered to help negate these issues in the future.

      Single speed motors are naturally more sensitive than variable speed motors. The single speed requires vent holes, whereas the variable speed is totally enclosed. Plus the mechanisms that run the respective engines are different, making the variable speed more reliable, durable, and efficient. You might want to look into getting a variable speed

    Hello, I have a 3/4 Hayward Pool pump that starts, runs quiet then will stops after 30 seconds and I see some smoke coming from the front of the motor

      This is an excerpt from one of our motor troubleshooting guides:

      Motor gets hot and shuts down – Generally due to low voltage or being overloaded. Check that the motor is wired correctly. If the motor is configured for 230V and has 115V coming in, it will shut down after running 3-5 minutes. Check for loose connections. Check for undersized wiring. For a hook-up to the circuit box of under 50′, pumps of up to 2HP wired for 230V need No. 14 size wire, For pumps wired for 115V, the wire size must be No. 14 for 1/2 and 3/4 HP; No 12 for 1 HP; and No. 10 for 1 1/2 and 2 HP. Check that the motor is not overloaded. Does the pump have the correct impeller and diffuser for this motor? Is the impeller worn and rubbing on the diffuser.

    Hello, my F1500C Pump is not working nor making any sound at all. I have checked the plug. The GFCI reset nor the test will make it work and it makes no sound at all when plugged into a good outlet. Can you help me determine what I need to do, buy a new one, take it apart…?

    We just opened our pool and we went to turn on the pump and all you hear is a quiet humming and nothing works! I would assume its the motor? The whole pump is about 500-600 and a replacement motor is 130 but we think it might be bearings and the pump froze up? my husband said he might try and replace those? im not sure if its worth it?

      Replacing the bearings is possible, but it is noit easy. You can check out our guides a video here: How To Replace the Bearings in a Pool Pump Motor – Part I / Part II

      I usually suggest replacing the motor, because I know, you should get a few more seasons out of it. Whereas with a rebuilt motor, you are putting money into an already aged, and worn motor.

    Hello,
    Looking to upgrade to a variable speed option from our current Hayward. We received two quotes – $1290 Hayward and $1299 Pentair. Quotes include parts and installation. My question is, should we just be looking to replace the motor or replace the whole pump? (My dad suggested asking about the motor.).
    Thank you for your help!

      Whether you can use a replacement motor or just replace the whole pump is dependent on the health of pump housing. If the pump housing is showing signs of wear and tear, like cracks and leaks, it would be best to replace the whole pump. If the housing is in good shape, then a replacement motor is likely the easiest and less expensive route.

      What is the model number of your pump housing?

      1. Chris Avatar

        I think this is it.
        MOD: K48N2PA105C4
        I found the motor which matched this number:
        SQ1202
        This number was also on it:
        E25022

        1. Matthew Simmons Avatar

          The replacement variable speed motor would be the ECM27SQU, it is a 2.7 HP square flange motor. If you want to do a whole pump replacement I suggest using the Pentair Intelliflo, 011018.

    My pump doesn’t prime. I called an expertise n he said it’s in need of replumbling but he is not sure that would be the only problem and could be resolved after that. I have just moved into ”tis house n not sure how old is the pool pump n motor? What should I do? Please advice me

      There was not much description of the actual or what you have done so far to remedy it, so it is hard to prescribe a specific thing to check. But we have this guide for pump priming issue that you can read and try before replumbing: How To Determine Why a Pool Pump Won’t Prime

    My Pump is leaking water and stopped pulling water from the pull. A loud humming sound is coming out of the pump. I live in the northeast and the pump is 8 years old. Is it time for a new pump?

    1. Matthew Simmons Avatar

      That is a lot going on for one pool pump. Your problems could be solved with a gasket kit and a new motor, or you may have to replace the whole pump. My barometer on which to do is based on the health of your pump’s housing. The pump housing is the main plastic body of your pump, the motor bolts to it, and it holds the guts of the pump. If the housing is cracked, looks dried out, or is older than 15 years old I would change the whole pump. If the housing is in good shape, replace the motor with new gaskets and a shaft seal.

    Hi, can you offer any insight? I was opening my pool for the summer the other day and turned on the pump so that I could drain some of the water out. The pump started up just fine after being off for most of the winter however, it shut off after about 5 mins and will not turn back on.

      A couple of things, did it flip the breaker? Did you hear any pop, hums or other odd noises?

      Try to switch the pump to a different breaker; this will determine if the original break was bad or if the motor is the issue. If the motor is still non-operational, remove the motor from the pump and try spinning the motor shaft with your hand. If the shaft is frozen, then it is completely locked up needs replacing. If the If the shaft is free then we can go further.
