Get a new programer. EP2002 should be suitable. Check your motorised valves. These will be in beside the hot water tank and pump. There may be 1 3 port or 2 2ports. Microswitches fail sometimes. On a 2 2port system this means that the valve opens up but the pump and boiler will not come on. To check this find the control box, this is within 2 feet of the valves. Open it up and remove the 2 orange wires (remember where they came from). Separate them and turn on HW and CH. Check for 240v from each wire to earth. If you get 240v then the microswitch on the valve it goes to is ok. If not then replace the valve head.
