Possible Causes
How to Fix / Troubleshooting
Safety first: Unplug the spa before inspecting the pump. Do not run the pump dry.
- Check water level: Ensure the spa is filled to the correct level to prevent air from entering the pump.
- Remove debris: Clean the filter and suction area to reduce the chance of debris reaching the impeller.
- Listen after reset: Briefly run the pump after cleaning. If the noise persists or worsens, stop using the spa.
Loud mechanical noises usually indicate internal pump damage. The pump motor or complete pump/heater assembly should be replaced by a qualified technician.
