Is your cordless stick water pump not working as expected? Don't worry—most issues can be identified by the LED indicator and solved in just a few simple steps.
1. The Pump Won't Start
Before assuming the pump is faulty, check the following:
- Make sure the battery is fully inserted.
- Ensure the filter is installed correctly.
- Check that all wire connections are secure.
- Turn the pump off and restart it.
If the LED is blinking, use the guide below to identify the cause.
2. Understanding the LED Blink Codes
| LED Blinks | Meaning | Recommended Action |
|---|---|---|
| 1 | Overcurrent | Restart the pump. If the issue continues, contact customer support. |
| 2 | Undervoltage | Recharge or replace the battery. |
| 3 | Overvoltage | Use a compatible battery. |
| 4 | Stall Protection | Check the pump for sand, gravel, or other debris. Clean the filter and pump before restarting. |
| 5 | MOSFET Overheating | Turn off the pump and allow it to cool before restarting. |
| 6 | Commutation Error | Restart the pump. If the issue persists, contact customer support. |
| 7 | Phase Missing on Startup | Contact our support team. |
| 8 | Battery Connected Before Switch Was Off | Turn the switch off before connecting the battery, then reconnect the battery and restart the pump. |
| 9 | Hardware Overcurrent | Stop using the pump and contact customer support. |
| 10 | Offset Error | Restart the pump. If the issue continues, contact customer support. |
| 11 | Dry-Run Detected | Make sure the intake pipe is fully submerged before starting the pump. Never run the pump dry. |
| 12 | Water Temperature Too High | Allow the pump to cool before using it again. |
3. Stall Protection
If the LED flashes 4 times, the pump's stall protection has been activated.
This usually happens when the impeller cannot rotate freely because of:
- Sand
- Gravel
- Leaves
- Dirt
- Other small debris
Simply remove the filter, clean the pump thoroughly, reassemble it, and test again.
4. Startup Phase Error
If the LED flashes 7 times, it indicates a startup phase error.
Please contact our support team with your order number, details of the issue, and shipping address. We will offer a proper solution.
5. Low Water Flow
If the pump is running but the flow is weak:
- Check whether the hose is clogged or damaged.
- Clean the filter.
- Flush the hose if necessary.
Keeping the filter clean helps maintain the best pumping performance.
6. Never Run the Pump Dry
The pump includes dry-run protection to help protect the motor.
Always make sure the intake pipe is fully submerged before turning the pump on. Running the pump without water may trigger the 11-blink warning and cause the pump to shut down automatically.
