Vokera Unica 36 HE fault code 10?

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?
