What should I do if the device alarms' low water inlet pressure 'but the municipal water pressure is normal?

This alarm is usually caused by the front end of the device: 1. Check if the inlet valve is fully open; 2. Check if the front PP cotton filter is clogged (due to increased pressure difference), and replace it if it is clogged; 3. Check if the inlet solenoid valve is working properly; If the equipment is equipped with a booster pump, check if the pump is running. You can replace the PP cotton filter element first (it is recommended to replace it every 3-6 months). If the problem persists, please contact after-sales service.
