Pump starts and then shuts off after a few seconds or minutes without displaying a specific error code.

Safety first: Turn off power before inspecting wiring.

• Step 1 – Check ventilation and temperature: Ensure the pump has adequate airflow and is not in a confined, hot space. Clear debris from vents.
• Step 2 – Inspect wiring: Tighten all power connections at the pump and panel. Loose connections can heat up and cause intermittent shutdowns.
• Step 3 – Monitor current draw (technician): A technician can measure current to see if the motor is drawing excessive amps before shutdown.
• Step 4 – Test at lower RPM: Run the pump at a lower speed to see if it remains stable. If it only shuts down at higher speeds, suspect overheating or overcurrent.
• Step 5 – Replace motor/drive if recurring: Repeated unexplained shutdowns often indicate failing internal components that require replacement.
