It might just be me being paranoid but I think my machine has not got as much power as it used to have. Its a ws201 pump and some idiot may have ran it dry for a second or two  
What would I need to change to get the power back?

Running it dry for "a second or two" wont damage the pump. Check any filters that feed the pump. Is it a return to tank unloader or return to pump? When was the pump last serviced?

Don't know when it was serviced last as I brought it second hand and have used it alot myself, it was return to pump but have just changed it to return to tank today and have used some sort of valve from another machine to blank off the port on the far side of the pump then just ran some 1/2 inch hose from the unloader back to the tank.

I would spend a few quid and get it serviced, if you dont have a machine then you dont earn any dough. The good thing about interpump is that the service kits are pretty cheap compared to the likes of cat. When you run the machine and have the trigger pulled, is the unloader still putting water back into the tank?

What parts would I need to service it myself?
Only a little dribble comes out the return when the trigger is pulled.

Here is a video of what to do that i put on here yesterday for another lad. The service kits can be bought off ebay, seals are the most common and valves. It would also be worth checking the pistons in the pump for wear

Set of seals and valves, maybe pistons.

This is often down to the feed pipe so check no obstructions. Occasionally the unloader vibrates loose so check this is set right otherwise max isn't max.

Failing that then could be seals etc as already mentioned.

Also change your nozzle, as the wear down then you loose pressure

Found a manual online

And the valves seem the easyist to change so i'll get some new ones and some new nozzles for the fsc and see it that makes a difference.
