The infrared water controller uses pulse (flow) mode. The water controller always prompts 3-ERR, how to solve it?
Cause analysis: The flow meter could not detect the pulse 30 times within 8 hours or there was no water in the water pipe.
Solution: Set up a rate setting card, swipe it on the machine. When there is no water in the water pipe, the water pipe is directly supplied with water.
The above methods are common methods to solve such problems. If you have other questions, please contact our company.
