my reset button begins to flash about 3 times a day, the radiators are not even on and the boiler seems to do the reset on its own, even when no one is in during day. i had my pressure vessel changed about 6 month ago !!! what should i do??

sounds like a new p.c.b is required. any reason why the expansion vessel was changed?
