Hi, I have a Ferroli Optimax HE 31C boiler.

After switching on, it returns the error code F37, as dictated in the manual, which is for low pressure.

However, I have already released the pressure valve and topped up to around 2.5 bars and it still returns this error (initially at 1.4bars, kept trying to turn it on and returning the same error every .1 bars above 1.4).

Anything I can try or should I call someone in person for this?

Thanks.
