Having problems with your Karcher G2650HHR Gas Pressure Washer ?

Engine runs,no water when trigger pressed. - Karcher G2650HHR Gas Pressure Washer


Answers :

Where the hoses attach to in the pump is a valve along with another valve inside of it. Remove both valves and clean and relube with Vaseline or equivalent. The inner valve will be the toughest one to remove and that its why it does not work if stuck inside so tight
Have you bled the air out of the hose? This is very important to do ... nothing will happen until the air is our of the supply hose. You dont say if this is done of not. Bleed out the air and try again.

I have a Briggs & Stratton gas power washer. This is the 1st time this year that I have used it. I put in fresh gas, hooked up the water supply. The engine started and then quickly stopped. I had to release the water pressure in the hose before I could pull start the engine. The only way to keep the engine running is to hold down the spray nozzle trigger. Once that is released the pressure in the hose builds up and the engine stops.


Sounds like the unloader is not working correctly. Try replacing it and see what happens. ... Briggs & Stratton Prosumer 20324 Gas Pressure Washer

I have had 3 Karcher pressure washers all experience the same problem and so have two of my neighbors. Our area has very hard water and it causes problems with the washer not bringing up the pressure when the trigger is pulled (or surges up and down) and the nozzles clogging, etc. The service repair facilities cannot tell me how to prevent this. Many attempts to contact Karcher for advice have been ignored. I have been thinking that perhaps running the engine for a few seconds with no hoses a


If your water is that hard (and it appears it is) WD40 will NOT solve the problem. You should look into a water softener. However, chances are that a small, inexpensive model will not have the flow capacity required for a pressure washer. You'll like ... Karcher K2.26 Electric Power Washer

We have a Karcher G2500VH pressure washer. If you start the engine with the trigger pulled on the spray wand it will run at full pressure until you release the trigger. after that, when you pull the trigger it will not have any more pressure than the water hose feeding it. Does it have an internal unloader valve? What is the part number?

This is two things. One is the back flow check valve to the soap line is leaking. The other is the pressure switch on the output side of the pump. ... Pressure Washers

I have a KARCHER Model K 2401 which onstart up has normal water pressure rather than the high. I can usually get it to work by removing the tip, pressing the trigger and running some water through without the tip on. The i replace tip and it will usually retain the high pressure. If I stop depressing the trigger I have to go through these same steps. It is like it loses prime. It works well once I get it started putting out the high pressure.

I have a Husky pressure washer with a Honda 2600psi engine. Problem is, no water will come from the pressure hose. I connected the water w/out the pressure hose and water flows thru strongly. I then connected the pressure hose w/out the wand and water flowed thru the hose fine. When I connect the wand and pull the trigger, nothing. I have replaced the wand and that was not the problem. Please help.


Check the quick disconnect to the wand these are spring operated and can get stuck ... Pressure Washers

I have Karcher 520m and when you press the trigger you can hear what sounds like a relay engaging but there is no water pressure, then it will fire up and work, but next time you press the trigger the same thing happens, I have been using it on harvested water, but even connected to the mains it does the same thing. Its now got to the stage it doesnt want to work at all.

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 pre ... Briggs & Stratton Pressure Washers

Hi there, I have a Karcher 2650 pressure washer that only pulses, does not reach high pressure consistently. Engine is running fine, filter has been cleared out, water pressure is OK. I even took out the cylinder under the black cap & checked it for deposits and greased it, still no go.


This can be a problem with the pump unit. Actually the collector to be more precise. Also, the pump itself. Either may develop a hairline crack and allow pressure to seep out, and tells the pressure switch that it has lost pressure... so it comes bac ... Karcher Pressure Washers
