Portercable Pressure Washer Model PCH2401

I have this pressure washer and it stalls the motor out a after using for 10 minutes or so. I tried to start it again and it was hard to pull.I disconnected the water supply and it started up right away. I noticed the pump was very hot.I connected the water supply again and it ran for a little and shut down again.Pump hot again. This unit as a thermal relief on it could this be defective causing the pump to heat up therefore load the motor down and causing it to stall out. The pump on this washer is ANNOVI REVERBER MODEL NO. SJV2.5G27-1 Any help would be appreciated

When the trigger for the wand is not pulled , there is a pressure relief valve that bypasses the water in the pump and so there is no pressure until the trigger is pulled again.
with the pump getting hot and not being able to pull the motor to restart, it indicates that that pressure relief valve has jammed ( faulty ) and the pump is running at full pressure all the time
That will heat the pump and stop the engine from restarting
That valve is where I would start looking for a problem

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: 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.

Sounds like the unloader is not working. try replacing it and see if that helps.

SOURCE: Pressure Washer Pump and Engine Stops Suddenly

The pump might be binding against the motor, causing the pump to overheat and temporarilly "seize up" and shut the engine off.
After cooling down for a brief period (5~10 mins) the engine can usually be re-started, but the overheating problem will keep coming back.

This happens when the pump either wasn't seated against the engine properly during it's initial instalation, or the pump housing wasn't machined properly and the PTO shaft is trying to drive the pump at a slight angle = excessive friction = overheating.

Try this:
1) Loosen the bolts that mount the pump to the engine just enough so that the pump can be wiggled slightly.
2) With the engine power switch in the "OFF" position, slowly pull the recoil starter rope so that the engine / pump completes about two revolutions. This helps to align the pump surface with the engine.
3) Lightly snug the pump mounting bolts in a criss-cross pattern, then slowly pull the recoil starter rope again to ensure that the pump isn't binding.
4) Finish tightening the pump mounting bolts in the criss-cross pattern (approx. 21 foot pounds torque).

The entire process should take you roughly about 10 mins from start to finish.

If this doesn't remedy your problem, then try running the engine for 20 mins with the pump COMPLETELY removed so as to isolate the components.

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.

Engine starts then stalls after 3 or 3 minutes of spraying. Then when I try to restart pull cord is really hard to pull.


When starting make sure you pull the handle to spray so it relieves the pressure from the pump an engine

It will crank and run good for 10 minutes and shut off. Once it shuts off when you restart it, it will only run for a couple of minutes and shut off again ?


I would start by getting a can of carburetor cleaner and have it 'at the ready' and try the 'start, run stall, start run stall' operation again. Only THIS time, once the engine begins to stall, give it a couple of quick shots of the cleaner into the air filter to see if it stays running on the cleaner.

If it does, then it's still a fuel problem. If it doesn't, then it probably an ignition problem. I would be sort of leaning towards the ignition coil getting weak. The reason I'm saying that is your statement about it running (I'm assuming cold start) for at first, 10 minutes then it stalls. Start it again and it runs for a couple of minutes and stalls again.

This could possibly be from the coil getting warm/hot and not producing the needed spark. After a 10 minute run it simply gets too hot and stalls the engine. After the next restart, the coil is already warm from the engine and so it don't take as long for the coil to get hot and stall the engine again.

Hope this makes sense and helps you out.

Not enough water VOLUME and pressure to supply the pump with a steady flow of water. Water is cavatating (adding air to the water) and the piston is heating up and jambing. Try using a larger size hose diameter and a shorter hose to supply the pump.

The engine starts cold after 2 or three pulls, runs ok initially, but seems to have slightly less power. After a few minutes I can turn off the choke. When teh engine warms up and runs for about 15...


I would first try draining the carb bowl, if you look at where the choke lever is and look below that you should see a clear red tube with a flat head screw below that, if you just turn the screw out the carb will drain. If you still have an issue you are going to have to clean the carb.

I started the motor and it ran about 30 seconds and it cut off . I then tried to pull start it and it would not pull easy it pulled hard til i could not pull it anymore.


I get this question a lot, and 9 times out of 10 the reason it because there is pressure in the pump. After the unit shut down did you pull the trigger to release all the pressure from the pump before attempting to restart? When these units have pressure in the pump they are near impossible to pull start.

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.

Losing pressure more and more often, especially


not quite sure where to get the parts, but if the pressure starts out ok and decreases as it runs, it is generally that the piston rings/seals are worn out, this can happen just from sitting up over the winter.

You can google Honda Pressure Washer Parts to find a supplier for the seals/rings
