No DHW on a Laars boiler

Hi I have a Laars Endurance EBP 175. I have good heat. But no DHW. Boiler won’t fire up. Change Flow Switch. Still don’t work.  Please help.

    It could that the diverter valve has failed and is stuck in the position for space heating.
    It could also be a dirty heat exchanger that needs descaling.
    Not enough info to go any further.
