"Been installed 4 year's and from first installation E133 fault constantly flagging. We've carried out every thing baxi engineers suggested work to be carried out and we've put up with resetting faulty boiler. So after 4 plus year's enough is enough of engineer visits carrying out work nothing related to the E133 fault or is there a serious electrical problem with the main board they don't want to address, now they are using health and safety issue of confined space issue working on boiler time I think to rip it out and fit another reliable brand"
