SOURCE: pressure washer wont run unless choke is on

I have a Karcher pressure washer w/ a 5hp Honda engine. It only will run while the choke is pulled out and only runs at about half the rpm's. When the choke is pushed in.. it coughs, sputters and shuts off. Can you tell me how to fix this....

SOURCE: pump on my pressure washer will not pressuerize

there is a loader and unloader valve on your pump bolted to it. if it frozen in the open position it will never build press. most of the time this is caused by leaving cleaning solutions in system after use and let set up for a long period. it causes the aluminum case to corrode.;you will have to dissassemble and clean if not to bad. if not your going to have to replace.

SOURCE: Can't fine where to put pump oil in

Dear glenoaks06,
I handled various Karcher washers, but the 2500 I never came across it. Just the same I will give you a few hints and maybe the solution for the problem. When the oil is milkey this means it has water in it. This means that there are faulty seals for sure. Now in many Power Washers the compartment where the oil is located is filled with oil prior to assembling the head unit that contains the pistons. So you have to take apart the the complete head change all seals( HP seals, LP seals and OIL seals). There are pumps that take multi-grade oil(15/50) and others 90 grade oil. If your pump is fan cooled, it probably takes 15/50 oil. Now one of the main biggest problem of water in oil is Faulty and Scratched PISTONS.
So when you have the pump apart....check condition of pistons. It is useless to change seals if pistons are damaged.
Now one thing regarding your problem, is that you have to put together the head with the pump upside down, so that you can fill the compartment (where the pistons are pushed by the swash plate), with OIL, before you put back the complete head with good pistons,springs,seals, valves...etc..etc. These few hints are relevant to quite a number of Karcher washers.
Regards,
Fulltech.

SOURCE: where is the unloader valve on my pressure washer

is not necessarily a cap, but could be a screw in plug, that should be close to the hose hook-up on the pump Inside there there should be a round ball and a spring that you can tighten or loosen to adjust the unloader and if it has been used ALOT, where the ball seats there could be grooves cut in there and you might need to get a valve kit to fix it

Why is there no water flow through on pressure washer?


Sounds like a pump failure. Does yours freeze in winter? Need to winterize like cabin plumbing.
Repair/replacement of pump could be close to new unit.

Water sprays out from underneath. The water is spraying forward and to the right. Is this a common gasket failure issue? Or do I really need to take it all apart? (sigh) I have so much else I have to do...


i'm sorry to say but if you happen to have a vertical motor you'll be better off buying a new pump for 150.00 online.if you see the casing is made of pot metal which corrodes from the impurities of water mainly chlorine.stay away from pressure washers that have a shaft downward like a lawn mower they much like consumer use only for residential 1 to 3 times a year.find one with a horizontal shaft where you can have a much better chance of getting it fix or get replaceable parts for.feel free to question me i've been in this business for 30 years.
ps a replacement pump with a solid brass head would be better the main killer to these pumps is that they leave the unit running with trigger closed which causes pump tp rapidly heat up and cause failure you must squeeze trigger within 3 to 4 minutes tops so that the heated water in pump head has been released.

I get "Sud" display and


The F35 indicates that the main control board detects a problem with the analog pressure sensor (water level pressure switch) in the washer. This component senses and controls water level in the washer. This failure could be caused by a pinched or broken air hose between the air trap at the bottom of the washer tub and the analog pressure sensor. It can also be caused by a clogged air trap or a failed analog pressure sensor. If you are able to unplug the washer and pull off the top panel, you can check for the probable cause of this failure.

To remove the top panel, remove the screws on the very back of the panel that secure it to the washer cabinet. Pull the top panel back slightly and then and off of the washer. It is on the side wall just behind the expansion control board. You can check the air pressure hose connection and the wire harness connection on this component.

This component costs around $99.This information was based on the general description of the washer model that you provided (Kenmore Elite front load washer). There are several different models of this washer.

It does not take much to damage the pump impeller or motor. Since the error code can be generated if the drain cycle exceeds 8 minutes, if the pump is damaged and can't pump at the required volume, the error code will continue to appear until the pump is replaced.

Had presure tostart cleaning @ then press. stopped just seem to have water press. thank you


if the motor is still running fine when this happened it is either a failure in the linkage between the gas motor and the pump. or the pump itself. if it looks like the motor does nothing whatsoever. it may be the link between the two. if the motor does a little bit, then the problem may be with the pump. Try turning off the engine while spraying and see if the pressure drops at all

Washer won't fill or start cycle fault codes indicate pump failure. Changed the pump but problem persists


Seems that the controller thinks your machine is full of water. Water level pressure sensor may be sticky. May be blockage down air line to pressure sensor - try blowing into sensor end to clear.
(Always disconnect from power before attempting repairs).
