gloworm micron boiler

[emmkat]

HI

i drained my central heating system today to replace a couple of rads and check my 3 port valve as i think it is stuck on heating only. replaced rads and checked valve. needs replacing but didnt do it today. i filled the system up and bled everywhere sucessfully bur when i went to start boiler nothing happened. then after turning it on and off a few times it started but i got flashing lights on reset and on burner and no heat. my boiler is a glowworm micron 40ff. anybody got any ideas? thanks.

On the front of the Micron range (30-80) there are 2 led lights. One is the reset light and one is the burner on light. These flash in a sequence to represent a fault.

Is one faster that the other? alternating? one solid?

Depending on what the lights are doing depends on what the fault is.

NB
