Worcester Bosch boiler not working for hot water

[Kaps86]

My Worcester Bosch boiler works for the central heating system but doesn’t turn on for hot water. On the boiler the chimney sweeper icon is flashing and then 100. Not sure what this means or what I need to do? Can anyone advise as I’m clueless

You could start by telling us which model of Worcester Bosch you have, and by the sounds of it, it’s a Combi?

Have you tried turning it off and on again ?
