Pump display shows E07 and unit shuts down; may occur when using long extension cords or multiple devices on one outlet.

Safety first: Unplug the pump before changing any wiring or cords. Do not modify the plug.

Steps to correct supply:

• 1. Remove extension cords: Plug the Flowclear pump directly into a properly grounded outlet whenever possible.
• 2. Use correct cord: If an extension is unavoidable, use a heavy-gauge outdoor-rated cord (shortest possible length, typically 12–14 AWG depending on local standards).
• 3. Dedicated circuit: Avoid sharing the outlet with other high-load devices (heaters, large tools). Use a dedicated circuit if available.
• 4. Check outlet: Inspect the outlet for looseness or heat discoloration. If the plug feels hot after use, have the outlet inspected by an electrician.
• 5. Retest: After correcting the power supply, reconnect and start the pump. If E07 persists on a known-good circuit, the internal voltage sensing board may be faulty.
