How to fix the sensor faucet failure?

July 03, 2019

The sensor faucet uses infrared principle to induce water. When the faucet fails, how can we solve it? The following three steps will teach you to check and learn how to repair the faucet.

Sensor Faucet

1, sensor taps do not water:

First, determine whether the power supply is normal, and the main domestic power supply methods are: AC 220V transformer 12V and 6V; DC 6V (fourth or fifth alkaline battery) and DC 3V (two seventh or fifth alkaline batteries ), hand block in front of the infrared window to observe whether there are lights, part of the sensor faucet brand infrared window using single-chip control, power indicator in the water control part (installed below the basin), if no response, the initial judgment of the induction part Faulty, replaceable infrared probes. It is suggested that users who can't judge the faults, if there are other normal sensor faucets, can use the elimination method. First insert the infrared part of the plug into the faulty faucet water control part. It is easy to judge whether it is a fault in the induction part or a solenoid valve in the water control part, and at the same time pay attention to the possibility of all the plugs being free of contact or moisture.

2. The sensor faucet cannot hold water:

Excluding the foreign matter before the sensor window (the principle of the sensor is as long as the object responds within the infrared sensing distance range) and the indicator lamp is normal, check whether the water inlet filter of the water control part is blocked by sediment or other debris. If there is any problem, please clean it; if it fails to solve the problem, please open the solenoid valve and clean the valve core, spring, diaphragm, etc. of the coil and replace it. If you can't turn off the water, it means that the solenoid valve is broken, replace the new solenoid. Valve part can be. There is an experience on this side. If you can't hold the water, you can feel the water. If you find that the amount of water is getting larger, you can't keep the water after you leave the hand, but the water volume is smaller than when you use it. This shows that the solenoid valve is not faulty. Only need to clean the solenoid valve according to the above method and it can be used normally.

3, sensor out of the small amount of water:

On the one hand to see whether the water pressure and the pipe itself is small, on the other hand check the water filter part of the inlet side of the filter for impurities, on the one hand, consider the use of PPR pipe today, part of the construction of the pipe joints using hot melt, It is not ruled out that the hot melt excessively deforms the pipe and the amount of water passing through the pipe becomes smaller.
