Yes I am still looking for an answer.
if there is no fault code there may be a problem with your diverter. likely the diaphragm in the diverter is needing changing. also the microswitch may be sticking. the microswitch can be repaired by putting a little wd40 on the moving parts of the microswitch.

Hi, i currently own a Ferolli 31HC Optimax boiler and was hoping you'd be able to point out where both the diverter and microswitch are located. Thank you for your help.
here is where the diverter valve would be. the microswitch would be mounted on top of the diverter.
