Pressure washers have a habit of the motor seizing up if they are left for a long time without being used. I had a Stihl PW that did this but the end of the motor shaft had a hexagon socket in the end that you could put an Allen key into and work the motor free. Had it for 20 years and was a good tool but eventually the motor burnt out so I have replaced the PW with a new one (same make).
Look for the end of the motor shaft and see if there is some way to turn the rotor to get it moving (or if it's already free to move you will know that's not the problem).
If the capacitor has blown it should be fairly obvious as when they go it's usually with a big flash & bang and the capacitor blows apart leaving a black sooty deposit behind which you will have to ask Sweep to clear up!
As the machine is electrical & pumping water you should have it PAT tested by a qualified electrician after you've looked at it/done anything to it 'cos if anything goes wrong and someone gets hurt guess who the finger will be pointing towards.
