Having problems with your Karcher K2.26 Electric Power Washer ?

The motor keeps cycling on and off (about twice every second) when the pressure trigger is not operated. The unit seems to supply plenty of water pressure when trigger is operated.

Answers :

The motor is holding pressure in the line.
Check the manual.
I don't think it is supposed to cycle that much.
If it's not designed to do that, then there is a seal or a bearing that is leaking.
It's letting water pressure escape the hose by letting water seep back into the pump.
The motor is pushing more pressure into the line to keep up with the internal leak.
Two times a second seems like a lot, and the noise is probably annoying.
If the unit is new, take it back.
If it's doing the job, run the equipment until it dies, or else take it for repairs.

We had a similar problem with a paint sprayer.
Paint sprayers also hold pressure on a line, except the fluid is paint instead of water.
When the machine sensed a loss of pressure, it would cycle once to restore pressure.
After a while it was cycling constantly, just like your machine.
Working indoors with the constant noise was a nuisance.
I had the machine rebuilt, and used it for another year before buying a heavier machine.
I don't know if there is a business that rebuilds your equipment, or how hard parts are to find.

Whirlpool Dishwasher GU2548XTP- Dishes still dirty after it has run, especially the top rack. 5 (?) yrs old. Runs and grinds intermittently, no water seen under unit. Sometimes I add more water when it grinds, then it runs very quiet. Sometimes it doesn't seem to fill enough. Water supply good, inlet screen inspected not clogged. Not a lot of pressure shooting the water around the inside of the unit, as the detergent that bleeds through the slotted half of the detergent flip door isn't r

The inlet valve is OK, therefore the control board was not the problem. The impeller pump is noisy and inefficient, and must be replaced.Here is the part: ... Dishwashers

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 a model PW 2200 gas pressure washer. It suddenly lost it's high pressure the other day after working fine for @10 minutes. It's getting plenty of water, but the engine doesn't seem to rev up to give it the high pressure. The operating instructions say to check the oil in the engine, and the PUMP before starting, but I haven't found any place to check for an oil level in the pump????Any ideas, I'm very confused.

I have a 5HP Honda engine installed on a Excell pressure washer. While the engine readily starts, it will not continue to run unless I keep the choke setting nearly completely closed. When I activate the pressure gun, it seems to generate adequate pressure, however, when the trigger is released, the engine continues to run at the same rpm instead of the normal variable rpm that most engines operate at during idling periods. The engine will always cease running when I push the choke rod all the w

Bosch Exxcel model number SGS46E12GB had the check water light on a week ago, checked supply and cleaned filters, all good. light still on, got upset and slammed the door, light off. since then the unit will either wash stuff, or not. didn't seem the arms were spraying very well when I opened the door, so I bypassed the door switch tonight and put it through a pre rinse cycle. (I ran it with the bottom filters removed) upshot is the pressure of water was really poor. also, when I first turned

Have a Karcher kb4040 that continues to run constantly even when the trigger isnt pressed. Also water flows out of the detergant hose when im not pressing the trigger.

Hi, I have a Karcher K3 pressure washer. 18 months old, used maybe 6 hours total. For the past 3 hours of use the compressor/pump seems to cycle audibly but pressure at outlet hose seems constant, hence I did'nt worry. Now it does not start with switch on. I now hear a buzzing sound from the unit. The unit was last used 6 weeks ago. The unit was stored in the garage away from frost, it does not leak water so I don't think there is any frost damage, but just this buzz. Any suggestions would

Water supply to my Bosch SHE43CO5UC/17 dishwasher seems interrupted and not being supplied to the unit. Water supply to the unit is checked and confirmed available. What are the possible causes, i.e. stuck solenoid valve?

Could be a dirty hose filter or faulty inlet valve. Ther could be a leak and the bottom of the unit has flooded activating the flood safety which will cut the water supply. The pressure chamber and/or the hose pressure chamber to sumo could be bloc ... Bosch Dishwashers

Northstar Hot Water Pressure Washer (model #157322) While using the pressure washer the safety relief valve activated venting steam and hot water from it... I immediately shut it down and let it cool down. After it was cool, I turned on the water supply again and the relief valve was still spewing water from it. My neighbor said it was probably the "unloader" valve was stuck or damaged. I called around my area and it seems as though no one services my pressure washer.. Is there a manu

My Kitchen Aid KUDS01DJSS0 seems to have water going to the upper spray arm (I see water coming out of the unit just beneath the upper rack), but the pressure doesn't seem to be high enough to clean the upper rack. No evidence that water is coming out of the spray arm on the very top. Lower rack dishes seem to clean OK. I have already removed the whole upper spray arm assembly and inspected the flapper valves that the middle sprayer goes into. I suspect that it's not making good enough contac

North star petrol pressure washer. working fine, then no high pressure, checked water feed, water filter , pressure relief valve and gun nosall well work sometimes and keep working, when you release the trigger and try in again the pressure gone again. please help, many thanks, richard

Sounds like the regulator is sticking or is airbound. loosen the water connection and then tighten it back. Could also be that the trigger gun is faulty or needs adjustment. Hope this helped ... Karcher 2500 PSI Pressure Washer

My Karcher 411A seems to have lost pressure. Behaviour is this, when you press the water release on the spray gun you get 100% pressure for like 10 seconds and then it seems to dwindle down to 30-40% of its total pressure. When the pressure cuts down I can hear more noise coming from the gun sprayer aswell. So not sure if the problem is in the gun or the main pump unit ?

Sounds more like a clog on the intake side. Check the filter and the hose on that side. ... Pressure Washers

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
