When the following failures occur to the instrument, it may be that your sensor is broken.1) The water temperature shows E1, EE, 00, 99 or -- or the water level and water temperature jump randomly.2) The water level light is off or all on; the water level does not drop or drops rapidly or rises quickly; the water level light displays up and down, but does not display in the middle.3) The water level is displayed, but there is no water in the water tank. There is a big error between the displayed water temperature and the actual water temperature.2. How to choose a 2-wires or 4-wires sensor?1) Cut off the sensor signal cable. If there are 2 wires, select a 2-wires sensor; if there are 4 wires, select a 4-wires sensor.2) Observe the quick plug of the instrument sensor. If it is a 4-pin and 4-hole connection, select a 4-wires sensor; if it is a 2-pin and 2-hole connection, select a 2-wires sensor.3) Observe the indoor instrument. If the instrument sensor has only 2 screw interfaces, then it can only be connected to a 2-wires sensor; if the instrument sensor has 4 screw interfaces, then it is a 2-wires and 4-wires general-purpose instrument, please follow the original selection.3. How to do the wiring?Adjust the switch to the 4-wires position, and connect the signal wires to "red, blue, green, white" according to the color. If the display is abnormal, switch the wiring positions. (or let the quick plug of the instrument 180 degrees turning would be ok)==========Origin : Mainland ChinaType : Electric Water Heater PartsProduct Name : 4 Wires SensorWater Level Wire : Red/BlueTemperature Wire : Green/WhiteSensor Length : 39cmSignal Cable Length : 0.5m/20mConnection Size : 20mm (1/2") Internal ThreadOperating Voltage : 220VMounting Method : Bottom-mountingSensor Material : Stainless Steel
