SOURCE: No pressure in the pressure washer

Leaving the hose on shouldn't cause a problem so don't panic. It sounds like you could just have a dirty nozzle. Try sticking a pin or something in the end of the nozzle (machine not running) and giving it a clear out. also if it is a two peice gun, split it and tap the squirting part on something clean like a workbench to clear any debris that might have got in there.

SOURCE: I have a dewalt 3750

I worked at a tool rental center while attending college and learned many tips and tricks about Dewalt and other brand pressure sprayers. Your machine probably has a 13 hp honda and has max pressure of about 3500 to 3700 psi. Most of the problems that customers had were engine related due to severe working conditions including totally wet engine /plug, wet air filter, and or other problems that were easy to remedy. We would set the pressure regulator to minimum pressure and explained to the customer how to increase the pressure as necessary but only after the engine was completely warmed-up to running temp to prevent engine stall. Your machine has a throttle lever between the tank and carb that should be set to max if you are going to set pressure at or neer max range. Most cleaning jobs do not need much pressure. Use lowest pressure to get the job done. Your engine developes around 13hp at about 3600rpm. If you want to maximize the life of you sprayer, then use your machine at about 70% of capacity or about 2000 to 2500 range that will allow you to run your engine slower increasing lifespan. Your sprayer is likely rated at 4 gallons per minute so make sure that the tip is that capacity. The tip has the size stamped which would show the fan degree and flow in gpm. The wrong tip, say a 3.5 gpm will strain the engine to point of stop because the smaller tip increases pressure. Most engine stall is due to high pressure setting on new machines. Lower pressure when warming-up machine and use max pressure rarely when necessary to max life. Please email for other information/questions or simple tests to determine faulty parts, good luck.

SOURCE: pressure washer stalls out when wand nozzle is released

common for not starting unless trigger engaged as you are turning the pump as well as engine creating pressure,as for stalling pump has unloader valve which is probably in need of grease(use good silicone grease)this allows water to ciculate when trigger released.

SOURCE: New Troy-Bilt 3000 psi - Very Hard to Hot Start

When you run the unit and shut if off, release the pressure from the spray wand before trying to restart the engine. This built up pressure will cause it to be very hard to start as you have found out. If it does not start on the second pull release the pressure again. Another option is do do what I did on mine. I simply put a pull tie on the handle so I can pull the trigger back and use the pull tie to hold the trigger open. Make sure if you do this, that you remove the high pressure orifice from the end of the wand before attempting to start the engine. Otherwise the pressure will come on abruptly and could injure you or do property damage.

Craftsman 2200PSI pressure washer, part #580.752700 dies when trigger off.


NEVER start an engine on a power washer with pump attached. You will damage pump and get no or very little pressure. Replacing pump only fix. Pump for this washer about $49. Check spring on carb for throttle open/close

I have a Craftsman 3.5 hp, 25 gallon compressor. The compressor runs fine, but will not build pressure. Tank has pressure from the last cycle so I know it is not leaking. The compressor runs but no...


Hi Jim,

Disconnect your main air supply from the comp head to the receiver/tank and see if their is a reasonable air supply to atmosphere.

If not check that air is being taken in by the head intake filter

Have a honda 5.0 hp engine on a pressure washer model belive is a de 1504 not sure of make, starts if you use starting fluid but then dies, getting gas to the bowl at botttom of carb but not to carburator


Hi there mburns44 i believe your problem is either that either the Air/Fuel mixture is too rich and causing it to flood or you have clogged jets. carburators are tricky and often times need to be cleaned or adjusted by a professional. I hope that this helps :)

Oil to gas mixture for a craftsman 3.75 hp pressure washer


There is universal 2 cycle oil available (pro-mix at Lowe's for example) that is good for all ratios from 16:1 to 50:1. With this oil you add the same amount of oil to the gas independent of ratio required. One gas can, no ratio worries. Hope this helps.

Will not release pressure and dies


Your unloader valve is not functioning. Take it apart and make sure it all the parts are able to move freely under the spring. You may need a new o-ring or two if you see damaged ones.
