1, no heating

(1) Turn on the electric kettle and turn on the switch. It is found that the electric thermos bottle is not heated and the water source is always cold. How to deal with the maintenance of electric thermos?

(2) Turn off the power first, and then check the plug and plug board of the electric kettle. If the weak contact is poor, you can polish it with sandpaper, and then check whether the fault is relieved. If it can run normally, it will be fine.

(3) If there is nothing wrong with the plug, it still doesn't give off heat. It may be that the overtemperature fuse is damaged. Use a multimeter to find out the specific reasons, and then carry out corresponding maintenance.

2. When the indicator light is on, the electric kettle will not come out.

(1) When using the electric kettle, it was found that it could run normally, except that there was no hot water. First, make sure it is not a power problem, and continue to troubleshoot other faults.

First, it is necessary to check whether the socket switch is in poor contact, and then it is necessary to check whether the rectifier diode VD 1-VD4 is open or open.

(2) If all the above are normal, you can use a multimeter to check whether the voltage is normal. If the voltage is normal, check the motor. If the voltage is 4-5 volts, it should be a motor fault, so you can consider the actual situation and carry out corresponding maintenance or overhaul.

3. Water leakage

In use, suddenly found that the electric kettle leaks, found that the electric kettle leaks, first find the cause of the water leakage, then look at the leaking place, and try to find the problem.

Generally speaking, the electric hot water bottle leaks. It is very likely that the silicone pipe joint is loose, and some may be cracked. We just need to plug it in again and fasten it.

Of course, if the silicone tube is seriously worn, it can be repaired or replaced according to the situation.

4, no heat preservation

First of all, let's take a look at whether the connecting terminals of its insulation circuit are loose. If there is a bad part in it, we can just replace the bad one directly, so it is easy to eliminate the fault by checking it slowly.

Second, the daily maintenance method of electric kettle

In daily use, you need to pay attention to the following items:

1, the rated power of electric kettle is generally large, and the capacity of power plug, socket and power cord should be properly selected. Generally, the specification of 10A should be selected. If the rated power exceeds 2200W, it is necessary to use sockets with larger specifications, and these sockets should be used independently to ensure safety.

2. The plug of the electric kettle generally has a grounding electrode, and the socket with a grounding socket should be connected. When in use, the power plug should be completely inserted into the socket.

3. Always keep the power plug, socket, power cord and automatic switch device of the electric kettle dry and clean.

4, water injection should not exceed the highest water level line, so as to avoid liquid boiling overflow outside the pot.

Water injection should not be too little, otherwise it will burn quickly. In addition, be careful not to turn on the power supply before filling the water, otherwise it is easy to burn out the heater or cause dangerous accidents.

5. When cleaning, the electric thermos can't be immersed in water, nor can it be washed with water, so as to avoid electrical insulation damage due to humidity, resulting in failure and leakage.

6. The electric kettle has been used for a long time, and there is scale on the surface of the electric heating tube. Scale not only affects the thermal efficiency, but also increases the heat in the tube sharply and damages the electric heating tube.

So check it regularly and clean it according to the instructions.
