Hot water heater relay tripping is a common issue that users may encounter while using it. Refer to the following Mytour article to understand the causes and solutions when your hot water heater relay trips!
1. Why does the hot water heater relay trip?
1.1. Due to weak electrical supply
If your home experiences weak or intermittent electrical power, it can cause various electrical devices, including the hot water heater, to malfunction. Even the hot water heater may not operate smoothly and exhibit relay tripping. This phenomenon often occurs more frequently during peak hours from 6 to 7 PM daily.
1.2. Water in the tank has reached the required temperature
When the water temperature in the tank reaches the maximum threshold, the thermal relay will automatically cut off to ensure user safety. Conversely, when the water temperature in the tank decreases, the relay will automatically close and supply power to heat the water.
1.3. Continuous operation of the hot water heater leads to overload
Continuous running of the hot water heater 24/7 for an extended period will cause the relay to operate continuously and become overloaded. This is a common cause of hot water heater relay tripping.
1.4. Hot water heater electrical leakage
The issue of hot water heater relay tripping can also occur due to electrical leakage. Specifically, electrical leakage incidents often occur more frequently in low-quality or old hot water heaters that have been in use for a long time without regular maintenance.
