Had same problem as others with Vokera Unica HE. During this freezing weather condensate overflow pipe blocked with ice. Cleared blockage. Left boiler overnight to dry out and after resetting many times managed to get it running again. Worked for a couple of days but has now packed up altogether and wont even attempt to light.(After a while fault code 10 appears )ls it possible there has been a component /sensor damaged due to the blockage? if so, where will it be located?
Vokera fault code 27 any ideas said high limit probe in book but cant find it

check the operation of the extractor fan. If it is not rotating the boiler will not ignite. The bearings in these and many other fans suffer from dry bearings owing to cheap and nasty components.
I have solved the problem by coating the bearings and lubricating the shafts with high temperature grease. If the fan does not run it will not ignite.

check the spark gap on the elctode they are prone to bending should be able to bend back

fault 10 is ignition fault, may be blocked condensate, no gas, faulty gas valve, faulty ignition.....
