1. Common troubleshooting of electric kettle
The electric kettle does not heat:
The fault turns on the power switch, the heating indicator lights up, and the water temperature does not rise. This fault is the most common fault of this type of electric water heater. Generally, the heating wire is blown or the electric heating tube leads to the oxidation and corrosion of the terminal, and the contact with the power supply line is poor and the heating is lost. The multimeter resistance file can be used to measure the resistance at both ends of the heating tube, if the resistance is normal. To the defending machine, the terminal is cleaned with sandpaper and then welded to make the joint firm, and the fault can be eliminated. If the resistance of the two terminals of the electric heating tube is measured to be several thousand ohms or more or infinity, the heating wire in the tube is blown. Need to replace with a new electric heating tube. The method is to first unscrew the faucet from the main body of the water heater, separate the water storage tank from the inner tank, and take out the inner tank from the plastic shell. The inner tank is divided into upper and lower parts, and the middle is fastened by washers and screws, and the lower two parts are After separation, use the electric iron to take out the damaged electric heating tube, and process the new electric heating tube Shab shell copper into a proper shape and weld it back to the original place. Check that the welded parts are not leaking. Finally, the unloaded parts are installed as they are. Add water to power the trial.
The insulation indicator lights up without heating:
The fault phenomenon turns on the power switch, the heat preservation indicator lights up, and the water temperature does not rise significantly. This fault is caused by the open contact of the thermostat switch burnt out. After replacing the component with the same specification, the fault can be eliminated.
After the electric kettle is boiled, it does not enter the insulation:
Failure phenomenon After the water is boiled, it continues to heat up and cannot enter the heat preservation state. This fault is mostly caused by the temperature of the thermostatic switch being loose or off, and the correct temperature cannot be felt. If the thermostat switch is well fixed, the thermostat switch is damaged and its internal contacts are sintered. It is necessary to replace the components with the same specifications.
The indicator light is not lit, do not boil water:
Symptom Turn on the power switch, each indicator does not light, and the water temperature does not change. This is because the electric heater has a large power, and the power switch is easily damaged by burnt or heat deformation. After the power switch is updated, the fault can be eliminated.
2. Electric kettle use precautions
● Add water first, check that there is water out of the water head, and then turn on the power.
● The water heater plug is a three-pin plug of the grounding wire. Be sure to use a three-hole socket with a grounding wire to prevent leakage and injury.
● Before the winter use, check whether the bottom is leaking. If the water leakage should be treated accordingly, it is prone to short-circuit accident.
● For safety, it is best not to have power overhaul.
