Worcestor Bosch 24 CDi combi prob?

Just one problem.... boiler turns on heating if boiler is powered up, even though program is set to OFF.
Hot water is fine, shower, taps etc.
Manual troubleshoot guide kind of leads to replacing circuit board, but Im unsure, any advice appreciated and thanks in advance.

Hi, thanx for reply. 24CDi doesnt have a flow switch, but prob is sorted now, was PCB, cheers.

Disconnect all external controls, frost stat (if fitted), room stat, internal clock.

Still firing?

Disconnect flow switch (two pink wires).

Still firing?

Yep, pcb.
