Had a blockage in the down pipe that the boiler condensate water feeds in to (now sorted), heavy rain sent water back up the condensate pipe into the boiler and out onto the floor.The boiler won't fire up anymore the fan runs but no ignition and then slow flashing of the blue light.Initially the blue light was flashing rapidly and no fan but having left it for a couple of days flashes slowly now but no ignition.Is it dead....

Your boiler is not installed properly, Worcester state an air break MUST be installed in the condensate to prevent this, you say it is now sorted, did you have an air break installed ?
It was installed in 2009 without an air break by eaga. I have unblocked the drain taking the water away, if it's fixable will get the air break fitted. It's had 10 annual services and no one has ever checked the condensate pipe.Also it was installed with the flow and return round the wrong way which was picked up 6 years after it was installed.
The flow and return reversed is no big deal really, just affects some TRVs and the HW cylinder will be slightly less efficient, but wouldnt do any damage to the boiler, will be fixable, you could go for a Worcester fixed price repair, covers materials and labour for the one price , you say it has had 10 annual services, bet it hasnt , bet it has had 10 annual safety checks, not the same thing, have you seen anyone removing the fan and burner and baffles and cleaning the inside of the heat exchanger ?

The flow and return was put right when the engineer spotted it when the system was flushed.As you say more like 10 annual safety checks. What has likely happened to the boiler after back filling with water via the condensate pipe.
Others will confirm, but given the age of your boiler, the water may have damaged the contacts to the gas valve, later models were modified to cure the problem by raising the gas valve/connections. You could get lucky and resolve the problem by drying out contacts.
Needs looking at by a pro really to diagnose fault.

agree most likely damaged the gas valve, not something you can sort yourself
Id say gas valve has been drowned at a guess.
