Assuming you have connected a heavy duty extension cord to the machine, since it requires an external power source, its possible the switch has gone bad.

I'd love to offer my help, but need the full model #. look on the base frame for the model # sticker. it maybe something like XR2600

Some of these pumps have a pressure bypass valve when you release the trigger on the gun it won't blow the hose ( safety feature) I could be that the vale is stuck

white smoke IS NOT fuel related. you twit! white smoke indicates oil consumption. they let anyone answer these things

The solution is very simple. All you have to do is change the spill valve.
This because the spill valve is not worth servicing. The actual problem is that the spill valve is leaking from its bottom-part seating. When you close the gun, the spill valve goes down, opens from the underside, and switches the electricity off. When you press the gun, the spill valve returns to normal, and if the underside does not close, you have low presure, because the water keeps circulating.

This is a vehicle? If you are having the issue that you said, this means the head is cracked or the head gasket is bad. The oil pressure is higher than the radiator fluid and therefore is getting into the cooling system

It sounds like the hole is relatively small. You can make a patch using a piece of sheet metal or a piece of flat aluminum which you can purchase at Lowes or Home Depot in the hardware dept. Use sheet metal if the metal surround is metal. Use aluminum if the surround is aluminum. You can tell which is which by taking a magnet and touching the metal. If the magnet sticks, it's metal not aluminum. Cut the patch using sheet metal shears to a size that is 4 inches by four inches larger than the hole. Then you'll have two inches on each side of the hole. You are going to need to put the patch on the inside of the metal, between the liner and the metal surround. This so the hole edges won't tear the liner. When you cut the patch, round off the edges so there are no sharp edges. Take duct tape and cover the edges of the patch. Place 1/2 the width of the duct tape and apply it to one side of the patch and fold the other half over to the other side. You can cut a round patch, but a square or rectangle patch will be easier. Just cut the corners round. Purchase a small tube of silicone sealant ( when you but the patch material) and apply a bead around the patch edges and in the middle. Then affix the patch over the hole. Wipe off any sealant that ozzed through the patch so it doesn't bond to the liner.

Yes it is not an engine problem it is the high pressure pump that stopped working as I was power washing
