E119 fault on Baxi or Potterton boiler

E119 is the standard low pressure fault for baxi, potterton and some other generic Baxi boilers like Mains. The fault is generated when the pressure goes below 0.5 bar. The simplest solution is to open the filling loop and increase the pressure.  You may have an external filling loop or a built in.  Check your instructions on how to use it.
