    Hello, I have an 80 liter boiler and from the very beginning when I have it, the plug heats up a lot and the cable is cold. I put it in another socket and the same thing. There is no looseness in the sockets, everything is tightened etc., the original plug is flooded, I don`t want to cut it off and use a new one. -warranty, of course you can call a service technician, but they come once every 2 weeks and waiting for them to come is pointless, and knowing them, they assume it`s not a plug but something else, etc., etc.

    There may be poor contact between the pins of the plug and the socket (the diameter of the pins is slightly smaller than the diameter of the holes in the socket and an electric arc is created) and this causes the plug to heat up, assuming that the plug itself is properly connected inside and properly sealed.

    Install a new plug with a pin and the problem is solved. Good luck.

    A plastic-covered plug often has a poor cable-pin connection, which leads to the contacts heating up and ultimately damaging the socket, so cut and carefully install the new plug.

    vol ez lie refer to the last post about the incorrect connections of the cable and pins, and the replacement of the plug itself

    A complete set is a must. New socket and new plug. Everything carefully assembled. Otherwise the problem will persist.

    But if you buy a new plug, choose the one with thicker pins (16 A). The socket is preferably new.

    It is possible that in another socket there is also poor contact between the plug and socket pins. However, first check the cross-section of the cable that goes to this socket. Maybe it is too thin for such a power consumption - 1500-2000W, because this is probably the power of the boiler, and that is why the cable and the socket and plug heat up. The cross-section should be 2.5 mm2, i.e. a diameter of approx. 1.8 mm. Then check the quality of the socket itself, whether it is tarnished or burnt, whether it grips the plug pins well and everything is OK. is replacing the plug itself or, in addition, the socket with a new one.

Topic summary

The discussion revolves around an 80-liter boiler experiencing overheating issues with its 230V plug, despite the cable remaining cold and secure connections. Several users suggest that poor contact between the plug pins and the socket may be causing the overheating, potentially due to the pins being slightly smaller than the socket holes, leading to electric arcing. Recommendations include replacing the plug with a new one, preferably with thicker pins (16 A), and ensuring that both the plug and socket are new and properly assembled. Additionally, users advise checking the cable's cross-section to ensure it can handle the boiler's power consumption (1500-2000W), with a minimum recommended cross-section of 2.5 mm². The quality of the socket should also be inspected for tarnishing or burning that could affect contact.
