That the hot water heater fault conditions: can not determine the user's electricity environment is normal (the surface of the outlet is to meet the requirements), the water heater is working properly, but the temperature is always rising less than the required bath temperature; that is, hot water heater Failure Analysis: In the analysis of such failures, first of all should be the use of water heaters and multimeters to analyze the user's electrical environment is first installed with the use of requirements; 1, the specific approach is: do not open the water flow, boot and set the water heater in neutral ), Then use a multimeter to select the appropriate range of water heater at the line measuring the line and the zero line voltage, and note the voltage value, are generally more than 220V, and then open the water flow switch and add a file and Maintain, and then use a multimeter to measure the water heater into the line between the line and the voltage between the zero line, and note the voltage value, and continue to add step-by-step and gradually measure the voltage, under normal circumstances, the general supporting water heater power and matching line Correct diameter, under the premise of the normal voltage 220V environment, the water heater in the most high-grade, the voltage drop will not exceed 1 5V, that is, when the water heater in the highest gear when the voltage between the line and the zero line should be about 205V; if the water heater in the highest gear or less than the highest gear, the voltage between the line and the zero line has dropped very serious, and even 200V are not, it shows that the user's environment where there is still some lack of wire diameter or meter is too small, or the inherent supply voltage is low; 2, if the measured voltage within the normal range , Then it indicates that there is a problem of the water heater fault, and should check the water heater according to the method of fault condition 13; Solution: 1 rearrange the user's incoming line, in order to achieve the required water heater environmental indicators; 2 Fault conditions User environment normal solution to the problem.
