Having problems with your Karcher PSI Electric Pressure Washer ?

I have a K3.91M karcher waterblaster that has had little use and it pulsates at idle what is the solution?


Answers :

A couple of other options spring to mind. It may be an air-lock, try disconnecting the high pressure hose and letting the water flow under its own pressure for 5 mins or so. It may also be a crack in the cyliner head...£16 from Espares..takes about an hour to strip and refit. you will need allen keys (to remove the cylinder head) and torx type screwdrivers for the casing.

I have a DPH3800 Dewalt pressure washer and the soaper isn't working properly. Right tip is being used but when trigger is not pressed it puts water into the bucket. When trigger is pressed it does **** some solution into the hose but very little and very slow. The valve is opened all the way. I know my former partner used bleach in the system which I read in the manual is a no no but it did work at the end of last season. Any ideas?

The last time I used the pressure washer was running fine. A few minutes later I tried to start it up and could barely turn it over. I removed the recoil and could turn it a little easier backwards. The motor is a Honda GC190 on a karcher pressure washer and has 20 -30 hours of running time. Thanks Clint

When I switch my karcher k4.97 washer on it just sits and pulsates(on off on off etc.)When I squeeze the trigger it runs perfect,Then when I release the trigger it reverts back to pulsating.It leaks water when sitting idle.


Well, first the easy bit... the pulsation is caused by the leak, because the machine can't hold pressure when the trigger is released.  The difficult bit is: what to do about it?  Unfortunately, there are several different places where the ... Karcher Pressure Washers

I have a Karcher K3.91M pressure washer that pulsates when the trigger is released (off). It works fine when turned on, pressure seems OK. Before this started the unit would just turn off until I again wanted to use it. Is it a problem ? Correctable? All connections seem tight & I see no leakage.

I have a Karcher 330 electric power washer. When connected and set to highest pressure (on variable wand) I get no motor action unless I reduce wand setting, then I get a little boost but not much. If I use high pressure conical wand I get high pressure sometimes, other times motor does not go and no pressure is delivered. I have replaced the high pressure hose.

I purchased my KARCHER G2500VH last summer. I used it one time for about an hour. I tried to start it today, seems like its not getting gas. I checked the gasline to make sure gas was flowing. I removed the sparkplug, poured a little gas into the engine through the plug hole. Replaced the plug, pulled the rope and it started for about two seconds. I also poured fresh gas in tank. Cannot get to start.

I used the "rinse only" cycle on the dishwasher a little while ago. I've never used this cycle before. After dinner I tried to start the dishwasher, but no other buttons on the panel respond except the last one I used, which is the rinse only cycle. I push and push, I tried pushing and holding, nothing works, I get no lights no anything. I've been using the "light wash" cycle for a long time and I normally just push the start button and the last cycle used starts automatically, so I wasn't a

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.

I have a honda GX240K1 on a BCS tiller. The engine seems to defy reason. I have adjusted the governor, set the max speed screw, adjusted the idle speed and have achieved some success but cannot seem to control max RPM's. The engine max's out at over 5K. I have tried about everything I can imagine yet nothing seems to fix it. Spec's say that it should idle at about 1400 Rpm yet it seems to idle best at about 1800-1900.
