Home appliance water heater is an indispensable appliance in the home. With home appliance water heater, you don't have to wash your face with cold water in winter, but with the use of electric water heater, you will also encounter some problems, such as the common faults of electric water heaters? Does the electric water heater have these problems? The electric water heater often encounters various problems during the use process. Next, follow the decoration home network Xiaobian to learn about the cause of the home appliance water heater failure, and the related content of the appliance water heater maintenance method. !
Home appliance water heater repair method
Fault 1: During the heating process of the household appliance water heater, the small hole of the safety valve has drops of water. This is the most common phenomenon.
Causes of dripping: Since the electric water heater is a closed-type storage type electric water heater, during the heating or heat preservation process, the water pressure of the water heater inner tank is greater than 6Mpa, so that the one-way safety valve overflows and drops water drops.
Solution: Close the inlet valve and adjust the water mixing valve knob to a high temperature to avoid water leakage from the one-way safety valve and allow water to drip from the shower. If the mixing valve is not installed, the hot water ball valve can be opened a little, where the pressure can be drained, and the leakage of the one-way safety valve can be avoided.
Fault 2: The hot water in the appliance water heater is used for a short time.
Analysis of the cause: The first time the water heater is used (or the section is unused from the environment). Because the heating time of the water heater is short, the water temperature in the upper and lower layers is not uniform, resulting in less hot water.
Solution: Use the water heater continuously for more than 12 hours to make the water temperature inside the water heater uniform.
Fault 3: Leakage during the use of household appliances and water heaters. This is a very serious fault to pay attention to often.
Cause: 1 The air pressure switch is not properly adjusted. 2 The position of the suction nozzle is not appropriate. 3 Silicone tube peeling or cracking causes leakage and pressure loss can not push the wind film. 4 The wind pressure switch is out of order. 5 pulser failure.
Solution: 1 Adjust the air pressure switch to the appropriate position. 2 Adjust the suction nozzle. 3 Plug in or replace the silicone tube. 4 Replace the air pressure switch. 5 Replace the pulser.
Fault 4: The heating indicator is on but not heated.
Analysis of the cause: 1 poor contact or disconnection of the heating tube connector. 2 The heating tube burned out.
Solution: 1 Check for exclusion. 2 Replace the heating tube.
Fault 5: The heating indicator is off and cannot be heated.
Analysis of the cause: 1 Poor contact or disconnection of the thermostat connector. 2 thermostat blown
Solution: 1 check for exclusion. 2 Replace the thermostat.
Fault 6: The indicator light of the appliance water heater has not been extinguished.
Analysis of the cause: 1 The temperature sensing surface of the thermostat has less contact with the surface of the electric heating tube flange. 2 The thermostat is broken.
Solution: 1 Re-install the thermostat to make the temperature sensing plane contact. 2 Replace the thermostat.
Fault 7: During the use, the leakage protection plug is automatically powered off (regular automatic trip), press the reset button to reset and restore the power supply.
Analysis of the reasons: 1. Usually due to poor contact in the socket, abnormal temperature rise is too high.
2. Lightning, lightning strikes or leakage of electricity from adjacent electrical appliances, etc. will cause the grounding wire to instantaneously trigger the action of the leakage protection plug.
Solution: 1. Replace the high-quality socket (optional plug, pull force is relatively large, the plug is inserted into the tighter socket).
2. Check the copper pins of the leakage protection plug. If it is black, wipe the oxide layer with fine sandpaper. If the pins are deformed, correct them. The three copper feet should be perpendicular to the bottom surface and cannot be bent.
Fault eight: the water is not hot
Analysis of the reasons: 1. Improper adjustment of hot and cold water 2. The power is not turned on; 3. Electric heater is damaged; 4. The thermostat is damaged.
Solution: 1. Properly adjust the opening degree of the hot and cold water mixing valve; 2. Adjust the power plug or switch to make it in good contact; 3. Replace the electric heater; 4. Repair or replace the thermostat.
Fault 9: The effluent temperature is too high
Analysis of the reasons: 1. Improper adjustment of hot and cold water; 2. The thermostat knob is improperly adjusted or the contacts are stuck.
Solution: 1. Properly adjust the opening degree of the hot and cold water mixing valve; 2. First adjust the thermostat, then repair the contacts and replace the thermostat if necessary.
Fault ten: difficulty in entering or effluent
Analysis of the reasons: 1. Dirty blockage. The main reason is that the tap water quality is not good, the impurities are excessive, and the check valve of the water inlet is blocked. The electric water heater with the inlet filter is blocked because the filter hole is blocked; Steam block; 3. The water supply pressure is not normal; 4. The mixing valve is faulty.
Solution: 1. After determining that the water pressure is normal, clean the pipeline, impact the dirt or clean the filter; 2. Adjust the thermostat to the minimum position or cut off the power supply, discharge the steam, repair the thermostat and the dirty plug of the hot water valve, adjust and clean; 3. After the water pressure is normal, the fault disappears by itself; 4. Repair or replace the mixing valve.
The above is the cause of the failure of the appliance water heater, the detailed answer to the repair method of the appliance water heater, I do not know if you are satisfied with the introduction of the decoration home network Xiaobian.
