WashR PRO | The pressure drops during use
Noticing pressure loss during use? Here are some common causes and what you can do to fix them:
| Possible Cause | What You Can Do |
|---|---|
| Using an external tank for water supply | Switch to a mains water supply for consistent pressure and proper flow. |
| Nozzle is worn, dirty, or stuck | Remove the nozzle and clean it thoroughly. Replace if damaged or blocked. |
| Intake water is too hot | Make sure the water temperature is below 40°C (104°F). Use cold water only. |
