Flotec Pump Blows Relay Fuses: Isolate Motor vs. Wiring Fault

Flotec Pump Trips Relay Fuse Instantly: Motor Short or Wiring

Pump runs split second, blows fuse. Replaced fuse, repeats.

Isolation Test

1. Power OFF. 2. Disconnect motor power wires at pump. 3. Power ON, run controller. 4. If fuse holds → motor or motor wiring shorted. 5. If fuse still blows → controller/relay wiring fault.

If Motor Side

• Centrifugal start switch stuck.
• Motor winding short.
• Take to electric motor shop for test/rewind, or replace pump.

Flotec Note

Flotec = big-box brand. Motor shops often won't rebuild. Replacement pump may be cheaper.
