Midea water heater is not hot. What happened?

1, thermal efficiency reduction: As we all know, the service life of electric water heaters is usually about eight years. If the service life exceeds this life, the wear degree of heating rods will be aggravated, that is, the thermal efficiency will be reduced, resulting in the inability of water heaters to heat. At this point, the best solution is to replace a new water heater.

2, scale increase: I believe that friends who have used water storage electric water heaters know that there will be a lot of dirt around the heating rod, resulting in a longer heating time of the water heater. At this point, you need to clean the water heater thoroughly. Normally, the liner should be cleaned every 2 years or so.

3. The preset temperature of the thermostat is low: This phenomenon generally occurs when the water heater is used or cleaned for the first time, especially when it is used for the first time after changing seasons. Because the internal temperature of the thermostat can't meet the requirements, it can't be heated. At this time, you should raise the preset temperature.

1, the diameter of power cord used by electric water heater must meet the requirements of rated current value of water heater. The first use or maintenance, the first use after cleaning, you must first fill the water heater with water, and then turn on the power. The power socket must have a reliable grounding wire. When using, it is forbidden to pull the power plug with wet hands.

2. For families who don't often use electric water heaters, the frequency of use is not high. Such a family is electrified and heated one hour before taking a shower, and closed after taking a shower. Usually, the water heater is off.
