Davey Overheating Electrical Components

Pump emits a burning smell during operation.

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

Overloaded motor, Failing windings, Loose electrical connections causing arcing, Blocked cooling vents

Safety first: Turn off power immediately if you smell burning. Do not continue to run the pump.

Step-by-step checks:

1. Inspect motor exterior: Look for discoloration, melted plastic, or soot around the motor and controller.
2. Clean vents: Remove dust and debris from cooling slots.
3. Check load: Ensure valves are open and the pump is not dead-headed against a closed valve.

Because a burning smell often indicates serious internal damage, have the motor and wiring inspected by a technician before reuse.
