2. Common fault: the heating is not hot (the valve has been opened). The heating is half hot. There is water noise in the heating. Troubleshooting: there may be air in the heater, so it needs to be deflated

method 1: close the water inlet valve first. Open the vent valve to vent the collected pen valve. If there is water overflow, close the vent valve

Close 3/4 of the water inlet valve, and then close the water return valve. Open the vent valve to exhaust. This number is still rising. When there is water overflow, half close the vent valve

remind you: after operation, if the fault still cannot be eliminated, notify the maintenance personnel
