If its two wire it shouldnt matter... if it's multi wire then you are going to need a proper wiring diagram from them

Someone has hard wired the switch to always run because the switch was apparently bad at one time and in order for it to work they just wired it up straight. Remember to rate my solution Thanks in advance

I have a karcher 620m, power going to switch and coming out of switch but motor wont run, there is a white cylinderical item beside the switch with 2 wires and power isn't getting to it have you any...

The little white thing is most likely a capacitor, and only AC current affects this it blocks DC. These don't often fail, and if but if suspect, then replacement is the only way to tell?
You need to check at the actual terminals on the Motor to see if the power is getting there, it should be present at one side of the motor, the "Hot"side, and the other side or "Cold"side will contact to the Neutral wire, to complete the circuit. It is a very basic circuit.
You also need to check the motor is OK, While motor is disconnected, use a meter set to OHMS, and measure across the the motor's terminals, you should get a lowish Ohmic reading, if it is Open circuit, high Megohms, then either the Motor has "Blown" or the embedded protection fuses inside the motor have, either way the effect is the same the motor must be replaced. This is often what it is.
Below is a exploded diagram manual that may help, it's not all in English, but gives one a good idea.

I left my electric karcher pressure washer it in the shed during the winter and they tell me that the housing and the safety valve need replacing. Can I repair it myself? They want 180.00 to fix it which...

Is there a leak from the bottom ?
If so then there is a crack in the Manifold housing. A New Manifold Complete Replacement is approx. $61.03, can be purchased from Karcher.
If under 1 year old, and you can find a receipt, Karcher will replace the whole Pressure washer under warranty.
