Sounds like the regulator is sticking or is airbound. loosen the water connection and then tighten it back. Could also be that the trigger gun is faulty or needs adjustment. Hope this helped

well depends did u use it in cold tempatures if so no it was u. if not then most likely or could have been just a crazzy thought here that there was a electrical discharge when it was pluged in and cracked the block on it but honestly thats 1/10000000000000 chance of happening. or it overheated and cracked it but relistically if its new then just take it back and play dumb or if its still under warrenty play dumb and get it fixed. aslo u can search for a new part on craigslist or ebay. last but not least if its not uner warrenty or new to take back or u cant find a part either thru the ones i listed or by calling the man. ur last resort is to just throw it away.

From your posting, I assume you have removed the splash cap and the nylon bypass valve cover. Connect the water supply to the pump and connect the high pressure hose and wand to the pump outlet. Wad up a small towel and place it over the bypass valve opening to catch the valve insert when it pops out. With the engine throttle closed, pull the starter cord several times to see it the valve insert will pop out. If it doesn't come out after two or three pulls, set the throttle to low and start the engine. I have performed this procedure a number of times and the valve insert always pops out. There is no real danger of the valve parts getting seriously airborn since the actual pump output volume is very low (2.5 Gal/min).

It sounds like an air lock. Try this: With the machine off, connect the hose to the washer and let it run for several minutes to get all of the air out of the hose, and to purge any air out of the pump. Shut off the water, and connect the high pressure hose, but not the gun. Let the water run for several minutes. stretch out the HP hose and make sure that the air is displaced. Shut off the water, connect the gun, and purge as before. Now crank it washer up. As quickly as safe to do so, open the trigger to keep water moving through the washer. It should come up on pressure very quickly. It is better during normal operation to keep water moving through the system. When I am through for a while, I shut down my washer, but leave the trigger depressed to allow the pump to stay full of water, and cool. This prevents further problems when I restart it.
Hope this was useful.
