If the pressure is ok I would be checking the diverted valve,the motor has probably gone,there it depends which valve you have as to how you fix it,if it is the later boiler the valve has a cartridge which is always sticking. To be honest you really mead someone who is handy or better still an engineer to fix.there is a lever on one end you can use to manually override.
