In the event of power disruptions shortly after water heater installation, there are generally two possible reasons: Main Power Trip or ELCB (Earth Leakage Circuit Breaker) Trip. The potential causes along with their corresponding solutions for each scenario are as follows：
1. Main Power Trip
Possible Reason 1: The fuse of the switch is overloaded
For example, if a water heater with a power rating of 4.5kW is connected to a switch with a 16A fuse, when the power load exceeds 16A, the main power will trip. A water heater with a power rating of 4.5kW requires a switch with at least a 20A fuse.
Recommended solution:
Kindly arrange for a technician to conduct an inspection and replace the fuse switch with one that can withstand a higher load. Prior to the replacement, it's important to confirm that the total power supply and wiring in your home can accommodate the increased load.
Possible Reason 2: Sharing circuits with other electrical appliances
The power switch for the water heater is not on a dedicated circuit but rather shares the same circuit with other appliances. Since the water heater is a high-load appliance, simultaneous operation with other devices can cause a momentary surge in current, leading to the main circuit breaker tripping.
Recommended solution:
To ensure the utmost safety and reliability, we highly recommend having the skilled technicians install a dedicated circuit specifically for your water heater's power supply. This tailored approach minimizes any potential risks associated with power sharing among multiple appliances.
2. ELCB (Earth Leakage Circuit Breaker) Trip
Possible Reason 1: The fuse of the switch is overloaded
After installation, if the water heater's circuit breaker trips or the temperature display remains at room temperature without rising, it is most likely due to improper installation. This could lead to the burning out of the heating element. Overloading due to the damaged heating element can cause a leakage current, triggering the circuit breaker to trip immediately to prevent electrical hazards.
Recommended solution:
Feel free to submit a Home Repair Request and let our team of professional technicians at Esio take care of the rest. We'll conduct an on-site inspection and efficiently replace the heating element for you.
💡 Kindly note that the warranty will be voided due to improper installation, which has led to product damage. Any repair costs incurred will be charged to the user. Kindly liaise with the installation technicians regarding the issue.
Possible Reason 2: The dedicated circuit using RCCB (Residual Current Circuit Breaker) resulted in power trip
It’s possible that the dedicated circuit in the power panel box uses RCCB which is a switch using built-in leakage current protection. Since our water heaters already have built-in leakage current protection, if the dedicated power circuit also employs one, it could potentially cause interference and lead to abnormal operation.
Recommended solution:
For optimal electrical safety, we recommend having a professional technician conduct an on-site inspection to assess whether it's possible to replace the switch, thus preventing any abnormal operation.
💡 Typically, if the switch is labeled with the word "Test", it signifies that the switch is equipped with a Residual Current Circuit Breaker (RCCB).
Possible Reason 3: The Storage Water Heater is malfunctioning
The internal components of the storage water heater may be malfunctioning, which could result in a power trip upon starting.
Recommended solution:
Please submit a Home Repair Request and let our team of professional technicians at Esio take care of the rest. We'll conduct an on-site inspection and provide you with the necessary repair details.
💡 Kindly note that the warranty will be voided due to improper installation, which has led to product damage. Any repair costs incurred will be charged to the user. Kindly liaise with the installation technicians regarding the issue.
