I have a model 5000g. it might have 15 hrs. total running time on it. when i tried to use it last it would not build pressure. i took the pump apart and cleaned and regreased it. everything looked good. ive got good pressure to the pump but just a small spray out the wand. when running there is no real load on the engine. it has always been kept inside in a warm enviorment.

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: Karcher 3.97M Short cycles after trigger is released.

Dear csdamman,
There is a valve called the spill-valve. It is often called the control valve. This valve activates the micro-switch. When the gun is released, pressure builds up and compresses this spill valve. At the same time it puts off the micro-switch. This will then stop the machine. Now when the spill valve is faulty it cannot hold compreesion under pressure so it starts de-compressing and starts the machine again. This goes on in a cycle as you explained. So you have to change the spill valve. If the spill valve that operates the micro-switch is part of the upper head,...then the whole head must be renewed. Myself I rarely service Spill Valves. The best thing is to renew it. From your explanation it seems that you did not take notice of this Spill-Valve. Infact when you mentioned Pressure Switch, I do not know if you are refering to the spill valve. If you are....then saying that the Pressure Switch moves and operates freely, does not mean that it is OK.
In certain machines in the outlet...there is a small valve, coloured black and red or green and yellow. This sometimes when faulty, it gives the fault you mentioned. Sometimes an inlet valve gives the fault you mentioned. But from my expirience it is most of the time that the Spill-Valve is the fault.
Regards,
Fulltech.

SOURCE: Engine wont stay running

It is a diaphram carb. Doe's the primer **** straight gas or does it have air bubbles in it? If it has bubbles in it then it is a leak in the fuel line.
If not then Unhook the intake fuel line and pump the bulb until all of the gas is out of it. Then pour the gas out of the tank and rinse it out with new gas. Pour in new gas and it should be ok.

Sprayer looses pressure pump issue ?


You can take the intake part of the pump apart and clean/lube the diaphragm of the pump. If you didn't clean it out last time it was used there will be residual or cake built up. Make sure the down snorkel is clear and doesn't have any contamination in the tube. Check the screen/filter also.

THE PRESSURE ON MY FILTER KEEPS SPIKING. I TOOK


There may be a calcium build up on the fingers, and just cleaning them will not remove the calcium. I would disassemble filter again, then give the fingers an acid bath. Mix about 50 -50 muriatic acid and water and let elements sit in a bucket with the mixture for 15 or 20 minutes, then reassemble and see if this fixes problem. (the quick test is to let the pressure get real high, than add some acid to the skimmer and see if that lowers the pressure at all)

Water leaks from the door of countertop model on


My older model had cheap plastic type rivets around the window. Of course they broke and water leaked out the window. I took the door apart and put in a new gasket the siliconed the heck out of it!
Put dishwasher on a counter or floor and put a nice thick phonebook under neath the opened door for support. Carefully replace window with gasket and a bead of silicone. Put enough weight on top to press it down and seal it. Leave for 24-48 hrs. I've replaced the window 3 times and this fix has lasted 2 years now. total cost about $10 and a little effort. make sure you use heat tolerant silicone.

MAKE SURE TRANSMISSION FLUID LEVEL IS CORRECT. BUT THE TRANSMISSION OIL PUMP IS TOO WEAK.IT NOT BUILDING UP ENOUGH PRESSURE FOR THE FORWARD CLUTCH PISTON TO APPLY.ALSO YOUR FORWARD CLUTCH PISTON SEALS.COULD BE LEAKING.WHEN ENGINE GET WARM AND THE TRANSMISSION FLUID GET WARM.IT CAUSES FORWARD PISTON SEALS.TO EXPAND ENOUGH TO BUILD UP PRESSURE SO THE FORWARD CLUTCH PLATES WILL WORK.LOOK LIKE YOU ARE GOING TO NEED A TRANSMISSION OVER HAUL.

I had the same problem 3 years old, maybe used 10 times - removed the air filter and the washer started fine. The air filter looked fine - I have not tried to replace it or figure out the root cause. I was just happy to get it running again :)
