1. The water heater cannot be heated.
At this time, it is necessary to check whether the heating pipe of the water heater is damaged. If the heating tube inside the water heater is found to be damaged, you can take it out and add a new heating tube. If the fault of the water heater is not serious, a protective film can be coated on the surface of the heating tube to prevent the heating tube from contacting with water and causing short circuit.
2. Water heater leaks
If the water heater is found to be leaking, first turn off the power supply of the water heater and close the hot water valve. Then check whether the internal structure of the water heater is installed correctly, including whether the water heater pipes and leak-proof equipment are complete. If it is missing, it needs to be replaced in time.
3. The water temperature of the water heater is unstable
When the water temperature of the water heater is unstable, it is necessary to check whether there are users who use a lot of water from the water heater at the same time. If so, the hot water output of the water heater can be adjusted. In addition, check whether the water level of the water heater is normal, whether the water pipe is blocked, and clean it up if necessary. If the problem still exists, the temperature sensor of the water heater needs to be replaced.
4. Circuit failure of water heater
If the circuit of the water heater fails, you can first check whether the power cord of the water heater is connected properly and whether the power plug is damaged. If the fault still exists, it is necessary to check whether the fuses, relays and contactors inside the water heater work normally and replace them if necessary.
In a word, the maintenance of commercial rapid water heaters needs professionals, and it is necessary to check and maintain them regularly to ensure the normal operation of the equipment and provide quality services for the industry.
