Mend Worcester Bosch Greenstar Boiler Heating Thermostat

Worcester bosch?

No heat only hot water, changed batteries in thermo, it started up, then rads became boiling even though thermo (clock type) was on 15 degrees. Switched off and reset now it will only make 3 noises and won't start up except for hot water which is fine. Any help would be gratefully received!
