Mend Ferroli F30 Boiler Temperature Cold

How can I fix my Ferroli F30 combination boiler?

The water temperature keeps going hot and cold on all taps throughout the home. We have replaced the CH and DHW sensors and problem still occurs.

Does the burner light intermittently on both ch and hw this is prob the case and would indicate an air pressure problem. Check Venturis in fan. Check tubes from Venturi to pressure switch are clear. If both are ok then probably air pressure switch.
