| Troubleshooting | Situation Analysis and Solutions |
| Water leaks at the flange | After a long running time, the bolts are loose, or the gasket is corroded, or the system pressure is suddenly increased.
Solution: Tighten the bolts or replace the guard to restore the previous working pressure. |
| Electronic control failure | The electronic control is required to be waterproof and dry, and it is easy to fail when exposed to water. Generally, it is recommended to replace it with a new one. |
| broken shaft | If it is used for a long time, it will be rusted, or the larger impurities will enter into the brush and bind the dead brush.
Disassemble and weld, or replace the shaft with a new one. |
| Poor cleaning effect | The brush is worn out or the filter screen is clogged, replace the brush or filter screen. |
| The motor reducer is normal, but the brush does not rotate | Check for broken shafts, or disconnected connector locations. |
| Blowdown valve failure | Check whether the power line is normal. If it is normal, the blowdown valve has not been artificially damaged. It is recommended to repair it, or replace it with a new one, and it will be debugged normally. |
| Replace the shaft seal | Remove the upper cover of the filter, unscrew the motor reducer, loosen the coupling, gland bolts, pull out the transmission shaft from the inside of the upper cover, take out the damaged sealing ring in the stuffing box, replace it with a new one, and reinstall it. . |
| Water leakage at the shaft seal | Fine-tune the 4 compression nuts on the upper cover of the filter, and pay attention to the adjustment of the compression nuts evenly. |
| Shaft rotation noise is loud during cleaning | Properly loosen the 4 fixing screws, if there is no water leakage. Or add butter lubrication to the appropriate shaft. |
| Replace filter element | Open the upper cover of the filter, remove the connecting nut of the filter element, and pull out the filter element. |
