Possible Causes
Blocked motor ventilation, High ambient temperature and direct sun exposure, Overloaded motor due to high head or wrong impeller, Failing motor windings
How to Fix / Troubleshooting
Safety: Allow the motor to cool before touching. Turn off power at the breaker.
- Improve ventilation: Clear debris from around the Waterway motor, ensuring vents are unobstructed. Provide shade or a ventilated cover if in direct sun.
- Check load: Verify that valves are open and the filter is clean to reduce system head. Confirm the impeller size matches the motor rating.
- Measure current draw: With a clamp meter and pump running, measure motor amperage and compare to the nameplate rating. Excess current indicates overload or internal motor issues.
- Replace motor if needed: If the motor continues to overheat and trip its thermal overload despite proper load and ventilation, replace the motor assembly.
