Question about Coleman (100076) Compact Refrigerator
My pressure washer works at start up, but when I release the trigger it won't work again until I shut down the motor. I have to wait about 10 seconds, pull the trigger to release the pressure in the hose, start the engine again and it works until I release the trigger. Is there an adjustment that needs to be made or does the trigger need to be replaced? I have only used this 3 times since I bought it.
There is something wrong with your unloader. It is mounted to the manifold where your water outlet is. There are several parts inside the manifold that can cause this problem. They can be tricky to get out and back in. Sears Service can fix the problem, they work on pumps like yours...

I had the same problem. I took the hand apart and glue in a metal spacer to the tip on the handle that contacts the valve. I found that with pressure on the valve that plastic handle flexes just a bite not allowing the valve to pop open, by adding the spacer to the tip of the handle I took all the play out and gave it more movement to push on the valve. I also ground off a little peg to allow the handle to go forward more to allow the spacer in. For a spacer I used the a small piece of metal 1/16 thick, then glue it in with epoxy.

Pressure washers has this pressure switches where in as you press on the trigger, the washer works and if you release it, the pressure would build up high and it would trip this switch to turn off the motor or deflect the water to the by pass hose ( if the motor is not stopping) then as you press again the trigger, water should come out of the gun again but would not,
i have encountered the problem is in the pressure switch, even the pressure went down, sometimes it wont close the contact then the motor wont run ,
if the motor is continously running, then the trigger switch is the problem, the pressure excerted on the switch is so high that even if you press it , it won't open up to release the water.
what i can suggest is to tie the trigger in the gun so that it is always pressed and then just unplug the unit if you want to stop using it. it is an inconvenience but it will work.
or, open the gun and see if you can figure out why pressing the trigger would not open the switch.
another option is you can lower the pressure of the washer if it has an adjustable pessure controller. by lowering the pressure might open the switch when ever you press the trigger.
i hopw i was able to fix...
