the annoying thing about this boiler is that it wont give specific fault codes
YOU have to decipher the the sequence of flashing lights
RED and/or BLUE?
ON or OFF?
FLASHING FAST/SLOW?
even then you might only be able to narrow it down to half a dozen possible causes which would have to be individually tested to find the most likely culprit
the boiler book wont tell you HOW to test these components
you would have to ring up worcester tech support for advice
