If you experience a situation where the plug burns out during use, it could be attributed to one of the following three reasons:
- Extended usage period: If the water heater has been in use for a long period, the plug may experience poor contact or internal structural damage due to aging.
- Loose Socket: If the socket is loose, it can lead to poor contact with the plug, potentially causing overheating or burning.
- Exposed wiring: If the wires are damaged, such as exposure or deterioration, it may result in short circuits and subsequent burnout of the plug.
