Why does the plug from the extension cord in the outlet heat up when the heater is turned on?

The bathroom has a water heater. His cord is very short, and extended an extension cord from the corridor. Also, a cord from the washing machine was connected to this extension cord. So, when at least one of these two devices is working, the place next to the extension cord plug heats up, and there is an unpleasant smell throughout the house. What is the cause of this phenomenon and how to fix the situation?

    Hello! There can be several reasons for heating the plug: poor contact in the plug itself (you must either replace it if it is not collapsible, or disassemble and stretch the contacts). The second reason is poor contact between the socket and the plug, if the diameters of the plug and the diameters of the holes in the socket are not identical, the contact will be bad and the plug will heat up. Here you need to decide: either change the outlet (if it is an old model), or the plug itself to the euro. Also, heating may occur due to overload. If the cross section of the extension cord is not able to withstand the power of the included electrical appliances, heating will occur.
