I would be happy to advise you further and give you more detailed answers then the others have. Guessing at an engine or unloader problem will not actually assist you in getting your pressure washer up and running again. The most important question is, what is your pressure washer model number? That is the first part of this process. Honda is just the manufacturer of the engine that you have. They don't build pressure washers. If you can provide the model number, you should be able to find this on the cart or frame of the unit, then I can determine what pump you actually have and assist you in determining the actual problem to get your pressure washer up and running again. There are a few issues that can cause this problem, all of which can probably be repaired with minimal cost. If you can provide me with more information I would happy to assist.

You need to start the unit and let it run for few minutes to get worm, make sure the water is fully open and the unit is fully cleaned. Push on the trigger on and off for few times not letting the unit shutdown, then start increasing the fuel mixture ¼ turn and push on the trigger again and see…this could be that the unit need service or the governor springs getting week if you got one on your unit…let me know how that work for you and please do not forget to rate my service so we can improve on it with your help. God bless
Testimonial: "The problem was the governor spring. Thanks"

Hi It sounds to me like your unloader valve is stuck, this is the thing that is meant to move up and down when pressing the trigger.Please remove the unloader valve assembly and check for damage. If no damage is found then grease and lubricate this part and replace and this should work ok again.

Take hose and gun off pump.
Start engine.
See if pressure comes out of pump.
Next, remove water hose and look at filter washer.
Clean or replace filter washer.
Turn on water and it should come out of pump on other side.
These steps will tell you if problem is water supply or pump.
Sometimes the problems happen because the gun lever is bad.
Hook up hose but not the gun
See if pressure comes out hous.
These steps will tell you if problem is gun or hose.

This is a symptom caused by a sticking Unloader valve. The Unloader valve is inside the pump outlet body under the large black knob.

Before doing any dis-assembly try this procedure first. This may sound weird but it often works. We do this with a short piece of garden hose,,,,, Add 3 to 4 ounces of engine oil into the water inlet by pouring the oil into and old short / cut off garden hose with the end elevated but connected to the pump inlet.
Slowly pull the engine starter cord so as to pump the added oil into the pump and let it sit over night. Just keep pulling the starter cord "IGNITION OFF" until you note oil exiting the high the high pressure hose connection.
Then connect everything like you normally would the next day.
MAKE sure to purge the water supply hose of air at the pump connection before starting the engine.
Start the engine. NOTING that your going to shoot out the oil you put in the day before..... Pull the wand trigger every 3 to 4 seconds so you cause the Unloader / thermal relief valve to stroke within the pump body. Don't give up... you have to do this for an extended period of time so that you have HIGH pressure each time you pull the wand trigger.
With the engine still running.... let it run trigger off for about 1 minute at mid engine speed. Pull the trigger again and see if you have high pressure. Do another long pause... then use as you normally would.
IF the above lubrication process does not work....
The Unloader / thermal relief valve needs to be dis-assembled so that the springs and seals can be lubricated with Lubriplate #105 white grease. Make sure to also lubricate the casing of the pump body before putting everything back into the pump body.
Here is the white grease tube your looking for at any automotive parts supply.

This should get you going again. Just note that Unloader valves will notoriously stick after end of season storage upon the next use. It is important after an extended non-use period that the wand trigger is cycled every 3 - 4 seconds to exercise the Unloader valve springs and seals in the pump body. You only need to do this for about 45 seconds.
