Mend Worcester Bosch 28i Junior Boiler Heating Fault

burner light off - blue light flashes 5 times Greenstar 28i Junior WB?

Our boiler has no indicator burner light on (hence no heating/hot water)! I held down the maintenance button, the indicator came on and the blue fault light flashes quickly for 5 pulses then stops.
I can't find a manuel anywhere on line to say what the flashing lights mean only a useless user manuel. After a while the maintenance button (the one with the spanner) turns off as does the indicator light.

Can anyone help?

remember to reset boiler after you have defroze pipe by holding the reset button untill it resets the system !

yes your condesor pipe has frozen , you need to locate the black 3" pipe on the out side of your building (should go into the ground) you will find the water has froze inside the pipe and need to pur hot water over the black pipe from as high up it you can reach untill it melts ! common problem on these condensors, mine done the same last year and ive lagged it with pipe lagging ready for this years freeze !
dont using boiling water tho 1 for personal safety 2 it may split the plastic pipe worse shatter it ! waters got to hot enough to melt ice tho !

be carefull and its done in 10 min !
