the timer has not been touched could it be affected by the wiring of the valve perhaps??

It is not wired up correctly, or is the wrong one.

I guess you mean the three port flow share or diverter valve that takes water from the boiler flow and distributes this to either the hot water cylinder or central heating system. The valve is controlled by the room thermostat and cylinder thermostat. There are two types of valves and the wiring of each is different. A flow share valve will go to a mid position if both thermostats are calling for heat, whereas a diverter valve will either send water to the heating or hot water but not both together, usually giving priority to the hot water service. A microswitch in the valve will send an electric supply to the boiler and pump to operate these when the valve is activated. You will find either four or five wires connecting to this valve, usually brown, blue grey, orange and white. Generally it is the orange wire that activates the boiler and pump, the blue can always be taken as neutral, but this is where things may differ, brown and or white from the thermostats and grey the live connection that supplies power to the microswitch. You can see how easy it is for someone not following the wiring diagram correctly to get a connection wrong. I would say this is what has happened. The solution I am afraid is to get a copy of the wiring diagram, hopefully not thrown away or often printed on the valve actuator (motor) and trace all wires after first checking that only the blue wire is connected to a neutral. If you are not good at electrics leave well alone and preferably go back to to whoever installed the valve.
Do not take any notice of any one who tells you its an air lock or you radiators need bleeding. Some think this is the answer to any heating problem just to get points LOL

The only 3-way splitter I know of is for cable TV. But you say a valve. Usually, a valve goes to water or gas or something like that.
So, is this something related to a heating system? More info please.

do you mean 3 way motorised valve fitted to the central heating/hot water system?If this is the case then it is not the time switch ,but incorrectly wired and connected motorised valve.please do not fit any larger fuse than 3 Amp.in the circuit .check any control diagrams ,but better still get an electrician or heating engineer .better be safe than sorry.

I would suspect that the 3 Port valve has been misconnected.

check pump/fan/gas valve all of these are the cause of fuses blowing also rarely pcb on boiler
