Troubleshooting
Water Flow Issues
- No or Weak Flow: Check if the pump is clean and free of debris. Ensure the filter and sponge are not clogged. Verify the water level is above the minimum mark.
- Intermittent Flow: In Smart Sensor mode, flow is activated by motion. In Timed mode, flow occurs every 12 minutes. If in Continuous mode and flow is intermittent, check power connection or battery charge.
Noise
- Unusual Noise: Ensure the water level is sufficient. Low water levels can cause the pump to make noise. Clean the pump thoroughly as debris can cause blockages and noise.
