Pool pump repair: what each fault costs to fix
Most pool pump repairs cost about $80 to $400 in parts and labour, plus a call-out fee that usually runs $80 to $150 in Sydney. A new motor is $300 to $800 fitted. The rule of thumb: fix a single fault on a pump under about 6 to 7 years old, and think about replacing a pump over about 8 years old when the motor, bearings or housing go.
In NSW, see what a new 6 star pump costs after the rebate before you pay for a repair.
This guide is here so you know what a fair repair quote looks like, and when a new pump costs less. Capacitor, motor and wiring work is licensed electrical work in Australia, so there are no DIY electrical steps on this page. Isolate the power at the switchboard and leave those jobs to a licensed electrician, or a pool technician who holds the right electrical licence.
How much does it cost to fix a pool pump?
Here is what each common fault costs, fault by fault. The part price is what the part sells for on its own. The repair cost is what a technician charges for parts and labour to fix it, before any call-out fee.
| Fault and usual sign | Part only | Repair cost (parts and labour) | Worth repairing? |
|---|---|---|---|
| Call-out and diagnosisTravel, inspection and a quote | Not applicable | $80 to $150 in Sydney. Some repairers charge from about $200 with the first half hour of labour included. | Often credited against the repair if you go ahead |
| Lid O-ring, strainer basket or lidLeak at the lid, air in the pump | About $22 to $45 | Usually an owner fix | Always |
| Union O-ringDrip at a barrel union | About $5 to $22 | Usually an owner fix | Always |
| CapacitorHums but won't start | $22 to $120 | $80 to $200 | Usually. Licensed electrical work |
| Mechanical (shaft) sealDrip under the pump, between wet end and motor | About $28 | $100 to $300 | Yes, if caught before water reaches the motor |
| Motor bearingsScreech, grind or rumble | $60 to $80 a pair | $150 to $400 | On a pump under about 8 years old |
| ImpellerPoor flow, rattle, broken vanes | About $79 | $120 to $400 | Usually |
| Cracked housing (wet end)Water from a crack in the pump body | About $665 for one common model | Usually quoted as a new pump | Rarely |
| Motor replacementBurnt out or seized motor | Varies by model | $300 to $800 | Rarely on an older pump |
| New 6 star variable speed pump, installedFor comparison | Usually $1,000 or more | Usually $1,400 to $1,600. From $899 installed in NSW with the rebate | Compare before you pay for a big repair |

What each repair involves
Capacitor: the cheapest motor repair
Most pool pump motors rely on a capacitor to start and run, usually a single capacitor rated somewhere between 20 and 50uF. When it fails, the classic sign is a pump that hums or buzzes but won't turn over. The part costs $22 to $120 depending on the brand, and a technician typically charges $80 to $200 to replace it.
If you searched for how to replace a pool pump capacitor: it is licensed electrical work in Australia, so we stop there. A humming pump can also mean a seized motor, which a new capacitor won't fix, so it is worth having it diagnosed rather than swapping parts.
Shaft seal and bearings: act on the first drip
The mechanical seal stops pool water running along the shaft into the motor. A leak from the middle of the pump, or water coming out of the motor vents, almost always points to the seal. Caught early it is a $100 to $300 job. Left alone, water reaches the bearings and the motor windings, and the repair gets far more expensive.
Worn bearings announce themselves with a screech, grind or rumble that gets louder over time. Fitted, they cost $150 to $400. Seals and bearings are often replaced in the same job.
Impeller: blocked or broken
A blocked impeller is often just debris, which a technician can clear without new parts. A cracked or worn impeller needs a new part, which is about $79 for one common 1.5HP model, and $120 to $400 fitted.
Cracked housing or a burnt-out motor
These are the two faults where repair rarely makes sense on an older pump. The wet end and basket for one common pump lists at about $665 before labour, so a cracked housing is usually quoted as a replacement. A new motor costs $300 to $800 fitted, and replacement motors can run to about half the price of a new pump.
Is it worth repairing a pool pump?
Usually yes for a cheap fault, and often no for an expensive one on an old pump. Four checks decide it:
- Age. A single fault on a pump under about 6 to 7 years old, with parts still available, is usually worth fixing. On a pump over about 8 years old, a motor failure points to replacement.
- The half price rule. If the repair quote is more than about half the price of a new pump, replace it. Australian repairers and cost guides use the same line.
- Repeat failures. A pump 8 to 12 years old on its second or third fault, especially the motor, is usually better replaced.
- Warranty. Pool pump warranties normally run two to four years, and different parts of the pump can carry different terms. Check yours before you pay for a repair. Running a pump dry or having it wired by someone unlicensed can void it.
A repair also keeps your running cost exactly where it is. Pool pumps are star rated, and for pumps of the same power each extra star means around 20% less energy. Fixing an old single speed pump buys you a working pump with the same power bill. You can compare your pump with a 6 star variable speed pump in the pool pump running cost calculator, and see energy efficient pool pumps for how the star ratings work.
Can pool pumps be repaired?
Yes. Most domestic pool pumps can be repaired. Specialist workshops replace bearings, capacitors, mechanical seals, O-rings, impellers, wet ends, diffusers and fans, and some also repair pump controller circuit boards. A new seal and bearings can give an old pump a second life.
Repair stops making sense when the pump has internal corrosion or is very old, when parts are no longer available for it, or when the bill passes half the cost of a new pump.
Most repairs follow the same steps. The technician inspects the pump on site or takes it back to the workshop, then quotes. Good repairers won't start until you approve the quote, and repairs carry their own warranty: one Brisbane workshop gives 1 to 2 years on parts and 1 year on labour, and a Sydney workshop gives 6 months on its work. Ask what the warranty covers before you agree.
Repair the motor or replace the whole pump?
A new motor is the biggest single repair at $300 to $800 fitted. Compare that with:
- A new 6 star variable speed pump, installed: usually $1,400 to $1,600.
- The same pump in NSW with the rebate: from $899 installed.
On a newer, efficient pump with a sound wet end, a new motor can be worth it. On an old single speed pump, a new motor leaves you with an old wet end, old seals and the same running cost. In NSW, a motor quote in the middle of that range is already most of the way to a whole new pump.
How long should a pool pump motor last?
About 8 to 12 years is typical for a domestic pool pump motor, and a quality pump can reach 15.
What shortens motor life: rain getting into the motor, poor airflow around the motor housing, restrictions on the suction side of the plumbing, and a filter that needs cleaning. Water from a failed shaft seal is the other big one, which is why a small drip is worth acting on. The maintenance checks in our pool pump problems guide cover the basics, and how long to run a pool pump covers run times.
Testing a pool pump motor or capacitor
Testing a capacitor, the motor windings or the wiring means working on electrical parts, so it is licensed electrical work in Australia and we don't give testing steps. What you can do safely is note the symptoms before you call. Does it hum, trip the safety switch, screech, leak, or do nothing at all? That tells the technician most of what they need, and the call-out fee usually covers the inspection and diagnosis. The pool pump problems guide lists what each symptom usually means.
What a new pump costs in NSW instead
NSW energy saving schemes discount replacing an old pool pump with a high efficiency one, and the scheme rules cover replacing an existing pump whether it is working or not. Through Energy Rebate Check, a new 6 star variable speed pump is from $899 installed for most homes, and $1,049 outside Sydney, the Central Coast, Newcastle, the Hunter and the South Coast (Wollongong to Jervis Bay). The scheme incentives come off before you pay, and every pump carries a minimum 3-year warranty. You can also check your price on our NSW pool pump rebate page, which explains how the rebate works.
Your price comes back by text and email within a couple of minutes. Before anything is booked, you send photos of the pump, pipework and power point, plus a recent power bill, because the NMI on the bill is needed for the rebate. The install is done by licensed installers through the accredited provider your job is placed with and takes about 30 to 45 minutes. There is no supply-only or DIY option, because the scheme needs a licensed install and jobs are audited. If you are not sure what size pump your pool needs, the pool volume calculator works out your pool's volume.
Outside NSW, the rebate price doesn't apply, but the repair costs and rules of thumb on this page still stand. For what a pump costs to buy and install at normal retail, see what a pool pump costs in Australia.

FAQ
Pool pump repair: common questions
Most repairs cost about $80 to $400 in parts and labour: a capacitor $80 to $200, a mechanical seal $100 to $300, bearings $150 to $400 and an impeller $120 to $400. A call-out fee of about $80 to $150 in Sydney usually applies on top. A new motor costs $300 to $800 fitted.
Cheap parts like lid O-rings, baskets and union O-rings are always worth fixing. For the expensive faults, a common rule is to replace the pump if the repair costs more than half the price of a new one, or if a pump over about 8 years old has a motor failure.
No. Capacitors, motors, wiring and hardwired connections are licensed electrical work in Australia. Have a licensed electrician, or a pool technician with the right electrical licence, diagnose the pump and replace the capacitor. Fitted, a capacitor typically costs $80 to $200.
No. Energy Rebate Check doesn't repair pumps. In NSW we can send you the price of a new 6 star variable speed pump after the rebate, from $899 installed, so you can compare it with a repair quote.
Yes. NSW scheme rules cover replacing an existing pool pump whether it is working or not. Before anything is booked, you send photos of the pump, pipework and power point, plus a recent power bill.
About 8 to 12 years is typical, and a quality pump can last up to 15. Water from a failed shaft seal, rain, poor airflow around the motor and suction restrictions all shorten it.
A new motor costs $300 to $800 fitted, while a new 6 star variable speed pump is usually $1,400 to $1,600 installed, or from $899 installed in NSW with the rebate. A motor can make sense on a newer, efficient pump. On an old single speed pump, a whole new pump usually makes more sense.
