Standalone dry-run & overload protection for submersible pumps.
Platform: PFA01
The PumpFuse PFA01 Pond Pump Protector safeguards submersible pumps in ponds, fountains, waterfalls, and koi ponds. It monitors power draw, detects dry running or blockages, and automatically shuts off the pump to prevent damage — all on its own, with simple LED alerts.
The PFA01 protects your pump automatically in a few stages — no app, no Wi-Fi, and no configuration.
On installation or after a reset, the device enters Training Mode for 60 seconds. The pump runs normally while the device learns its average power consumption and sets thresholds for abnormal conditions. The blue LED blinks during training, then it switches automatically to Monitoring Mode.
The device continuously monitors power consumption in real time against the thresholds (average ± tolerances) learned during training. A steady blue LED means the pump is operating within normal parameters.
On a sudden power drop or rise, the device enters Warning Mode with a steady red LED. If the issue persists for more than 30 seconds, it escalates and the relay automatically switches off, disconnecting power to protect the pump:
With the relay off and the pump disconnected, press the LED button once to clear the warning and return to Monitoring Mode. If the problem is still present, the device will re-enter Warning (or Underload/Overload) mode as needed.
After addressing the cause, press and hold the LED button for 7–10 seconds to reset. The blue LED blinks as the device re-enters Training Mode and recalibrates its thresholds.
| Steady blue | Normal operation — pump is running within the learned power range. |
|---|---|
| Solid red | Warning condition detected. |
| Slow blinking red | Underload (e.g. pump dry running) — power dropped below the learned range. |
| Fast blinking red | Overload (e.g. blockage / clogged impeller) — power rose above the learned range. |
Single press: clear the current warning. Press and hold 7–10 seconds: reset and re-run the 60-second training phase to relearn your pump.

No. The Pond Pump Protector is completely standalone — it protects your pump and shows status via its LED with no app, account, or Wi-Fi. If you want phone alerts and history, choose the app-based Sump Pump Monitor.
On first run it trains for about 60 seconds to learn your pump's normal power draw, then monitors against that baseline. Hold the button 7–10 seconds any time to retrain.
Submersible water pumps in ponds, fountains, waterfalls, koi ponds and circulation systems running on 120V.
It isn't waterproof on its own, but it's compact enough to install inside a weatherproof enclosure.
