Mend Ferroli Optimax HE 31 C Boiler Pressure

overflow continually dripping on Ferroli Optimax HE 31 C?

we keep having to top up the boiler as its losing pressure and the fault '37' comes up but the overflow is continually dripping outside. Is there anything we can do without calling an engineer? Thank you in advance.
