Lobe Adi Pot prompts E3{ overtemperature} what should I do? Do you need maintenance? Just bought it for three days.
Overtemperature, of course, needs maintenance. But you can check the problem from the following aspects:

Overtemperature is mainly caused by insufficient water flow. First, check whether the circulating water pump works normally. If it works normally, see if the configured water pump meets the needs of the boiler.

If there is nothing wrong with the water pump, it is necessary to consider whether the temperature probe is normal.

It is best to consult the manufacturer or distributor of the boiler.
