Pool heater repair in Bowmanville, before you lose the swim season.

The gas side and the pool side

Many heater faults start outside the heater. A dirty filter or low water flow can trip the pressure switch, and the heater shuts down to protect itself. We check ignition, gas supply, controls, water flow and ventilation on natural gas and propane heaters, and tell you plainly if the pump, filter or wiring is a job for your pool company or electrician.

Free quote, warranty on the repair

Quotes are free and nothing gets added without your OK. If a part has to be ordered, you'll know how long it should take so you can plan around it. Repairs carry a Platinum Gas workmanship warranty, backed by more than 10 years in the trade, and evening and weekend visits make it easier to fit in.

Repeat faults are easier to trace with their history, so keep past invoices and error messages handy, and book heater checks around your spring opening or fall closing. Platinum Gas is based in Bowmanville and repairs pool heaters across Durham Region, Port Hope and Cobourg. Text the heater's make and model, a photo of the error on the display and what it does when you switch it on.

No heat or error codes

Diagnose a heater that will not start.

A heater that does not ignite or shows an error can have a problem with the controls, ignition, gas supply or operating conditions. The code helps direct the checks but does not confirm which part needs replacement.

Send the exact error text and describe what happens when heat is requested. We assess the sequence, explain the finding and quote the repair before parts or work are approved.

Shutdowns and inconsistent heat

Investigate a heater that starts and stops.

Repeated shutdowns or reduced heating can relate to the heater, water flow or controls. Note whether the problem began after changes to the pump, filter, valves or pool automation.

We check the relevant heater operation and explain any issue that needs a pool contractor or electrician. Do not bypass safety controls or repeatedly reset the heater while the cause is being assessed.

Pool-heater maintenance

Schedule the checks your heater needs.

Maintenance covers the cleaning and checks appropriate to the heater's model and condition. Arrange service in line with its manufacturer schedule and tell us about error messages or changes in performance.

Confirm seasonal opening and winterization responsibilities with your pool contractor. We can explain the heater-service scope and any fault requiring a separate repair, including parts availability or replacement options when relevant.

How pool-heater service works


  1. Send the model and symptoms

    Include the error display, when the fault occurs and recent pump, valve or control changes. Add a wide photo of the equipment pad only if it is safe to do so.


  2. Review the diagnosis and quote

    We assess the heater's operation, explain the cause and proposed work, and identify parts or separate pool-contractor and electrician input that may be required.


  3. Complete the service and check operation

    We carry out the agreed repair or maintenance and check the result. You receive an explanation of any remaining condition and the next service or seasonal-care requirements for the model.

Pool heater service questions

Answers about error codes, repeated shutdowns, repair costs and the difference between heater service and seasonal pool care.

What should I send with a pool-heater repair request?

Include the make and model, exact error message, what happens when heat is requested and when the problem began. Mention recent pump, filter, valve or control work. A safe photo of the normal display and a wide equipment-pad view can help; do not remove panels for photos.

Does a pool-heater error code tell you which part to replace?

It points to a condition the heater has detected, but further checks are needed to confirm the cause. Gas supply, ignition, water flow, controls and other pool equipment can affect operation. We assess the model and symptom before recommending a repair.

Should I keep restarting a pool heater that shuts down?

Do not repeatedly override a fault or bypass safety controls. Record the message and request service. If you smell gas or suspect an active leak, leave the area and call 911 and the gas supplier's emergency number from a safe distance; do not wait for a form response.

Do I need pool-heater repair, maintenance or replacement?

Maintenance covers the cleaning and checks recommended for the model. Repair addresses a diagnosed fault. We discuss replacement when the condition, recurring problems, parts availability or repair scope make it worth considering. The assessment should guide that decision rather than the heater's age alone.

What affects pool-heater repair cost?

Diagnosis, access, parts availability and the repair or cleaning required determine the quote. Water-flow, pool-plumbing or electrical problems can require a separate contractor. We explain the finding and proposed heater work before it is approved.

Does a service visit include winterization?

Confirm winterization separately in the agreed scope. Follow the exact heater's seasonal instructions and coordinate pool plumbing, water balance and circulation with your pool professional. A heater repair does not replace those tasks. Arrange winterization before freezing conditions and retain any error or service records for spring startup.
