FAQ

Q

Leakage protection plug trips

A
The tripping of the leakage protection plug is usually caused by internal short circuit of the electric water heater, poor contact of the power line, malfunction of the leakage protection plug itself, or environmental factors (such as lightning weather). The solution includes stopping the use of the electric water heater, checking the contact of the power cord, inspecting the interior of the electric water heater, replacing the leakage protection plug with a new one, and avoiding the use of the electric water heater during thunderstorm weather.
Q

Reasons for internal malfunctions

A
Internal faults may require replacing the entire leakage protection plug, inspecting the internal wiring of the plug, or replacing internal components of the plug. When dealing with these issues, it is important to pay attention to safety and avoid the occurrence of electric shock and other accidents
Q

Reset key malfunction issue

A
The fault of the reset button may be caused by load leakage (equipment aging, circuit damage, etc.), power overload, fault of the leakage switch itself, failure to press the reset button, and short circuit or overload of the circuit. The solution includes checking whether the electrical equipment is leaking electricity, reducing the number of electrical equipment used simultaneously, replacing the leakage switch with a new one, pressing the reset button, and checking the wires and equipment in the circuit to eliminate short circuit problems
Q

The problem of burnt plugs

A
Plug burnout may be caused by quality issues with the plug, poor contact, internal faults in the water heater, or aging of insulation materials in electrical equipment due to environmental factors such as humidity and high temperature. The solution includes replacing the plug with a new one, cleaning the plug to remove dust and dirt, repairing internal faults of the water heater, adjusting the environment to reduce the contact humidity and temperature of electrical equipment, and delaying the aging of insulation materials
Q

The release action time is too long

A
1. Increase the tension of the relay spring. (Replace the tension spring with a stronger one) 2. Increase the overtravel and final pressure of the dynamic and static contacts.
Q

The residual current is too large or too small to trip

A
1. Excessive residual current can be reduced by increasing the R4 feedback resistor 2. The residual current is too small to increase by reducing the R4 feedback resistor
