Elson Coral E water overflow

[Sergejs]

Hi,

I have an issue with my Elson Coral E water heater. My expansion tank constantly overflows and the water is constantly leaking into the drain. I have checked and the float valve is not the cause of problem - no water running from there.

I suspect that an element inside that controls the water pressure from the main does not work properly. Could you please tell me what potential issue could be? Could it be damaged heating coil that let water run instead of stopping it once the tank is full?

Thanks
Sergejs

Yes the heating coil in the tank has probably failed , new tank time I am afraid.

This is not something can be replaced?

you could check the float valve is set to the correct fill level,there will be a marker inside the tank.
