Shuangliren health pot was cut off in less than ten minutes, which was due to poor power contact. This situation is caused by poor contact of bimetal. If the water is not turned on, the power supply will be cut off, indicating that the power supply is in poor contact and the temperature sensing element is broken. This is one of the most easily damaged parts. The solution is to polish the contact point between bimetal and power cord with fine sandpaper, which can solve this problem.
