Possible Causes

Air trapped in pump, Debris in pump impeller, Worn pump bearings, Pump running dry due to low water

Safety first: Unplug the unit before accessing the pump.

Noise reduction steps:

Check water level: Ensure the reservoir is adequately filled so the pump does not run dry.
Bleed air: Tilt the unit gently to help release trapped air from the pump housing.
Clean pump: Access the Tristar water circulation pump, remove it, and flush out any debris from the impeller area.
Replace pump: If noise persists and the pump feels rough when turned by hand, replace the pump assembly.
