Certikin Overheating Motor

Pump motor casing is too hot to touch after running for a short period.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Blocked cooling fins, high ambient temperature, overloading due to high system head, incorrect voltage, failing bearings

Safety: Allow the motor to cool before touching. Isolate power before cleaning.

Clean motor body: Brush and vacuum dust from the Certikin motor fins and ensure airflow around the motor is not obstructed.
Check load: Compare running current to nameplate. If high, investigate for restrictions on discharge or suction.
Verify supply voltage: Ensure the motor is connected to the correct voltage and that there is no significant voltage drop.
Check bearings: Listen for bearing noise and feel for roughness when turning the shaft by hand.
