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 that it is easy to troubleshoot if we check it slowly.
