Delay in Combi starting DHW mode.

[sadone_uk]

Hi,

My Dad's Ravenheat LS100 combi every so often has trouble starting in DHW mode. It takes a little while to do anything, then the fan starts then a few clicks and it stops then it starts again with a few more clicks and it fires OK. Everything else including starting when CH demands it is fine.

Any ideas?
