1. The colour of the status light on the boiler control panel
and the number of times that it flashes indicates whether the
boiler is working normally, has a problem or requires servicing.
Fault - Warning When flashing green light indicates that the
boiler has detected a problem, and is attempting to resolve it. If it
does not succeed the boiler will go into lock-out mode and
will display a red light.
Fault - Lock-out When flashing red light indicates that the
boiler has a fault and has locked out. Press the RESET button for
a minimum of 5 seconds to try and clear the fault condition.
A lock-out condition can be re-set up to 5 times within one hour
using the reset button. Any repeating fault should be fully
investigated and appropriate remedial actions taken by your
installer or Baxi Customer Support.
If there is a continuous red light, contact your installer or Baxi
Customer Support and inform them of the fault code displayed.
