Check whether power supply is powered on normally, the indicator light on power on display will light up to show temperature, and it will not light up if not powered on. Under normal power on conditions, the water current is turned on, press the middle switch key, the machine starts heating, and the water heater displays: set temperature/water current/outlet temperature. If the temperature does not rise, there are two possibilities: one is that the temperature control switch (overheat protection switch) inside the water heater jumps, press the temperature control switch to restore it. The other is that the heating pipe is faulty, and the heat pipe can be replaced. If there is no heating, the display shows temperature, but water flow and set temperature are not displayed, indicating that the water flow does not pass through water heater, or water pressure is too low, or installation direction is wrong.
Note that water inlet and outlet must be installed correctly, but if the water pressure is sufficient, there is water flow and does not heat, then check at water heater inlet, it may be that something is stuck on the, causing water heater to not start. Recommended that length of water pipe at the water heater outlet should not exceed 3 meters. If it exceeds the length of the water pipe, there may be a water pressure difference, water pressure is not enough to start. (If the water tower is used in rural areas, the height of the water tower is required to be higher than 10 meters, so that the water pressure reaches the start value). Display shows that E1 is over temperature, E4/E5 or temperature sensor is faulty, first power off, run the machine with cold water, and then use it when it is powered on, pay attention to normal use of water flow not too small.
Heating tube failure shows E2, and heating tube needs to be replaced. Instead of leaving negative/neutral feedback or opening a dispute. Our listing price includes the value of goods, packaging cost, and export. Please check with your country's. We will reply your message within 48 hours.
