Having problems with your Karcher Pressure Washers ?

Karcher pressure washer keeps pulsing when not in use and has lost pressure when in use


Answers :

This can happen if the head of the pressure pump has split. You may need a new head, and to stop this happening again, tie the rigger open with a zippy tie. The water will run all time now and automatically bleed any air form the system. When you want pressure, turn it on at the main switch. This will prevent hydraulic hammer, (when you pull the rigge)r, which is what causes the head to split.

I have a Karcher 550M pressure washer and was using today when all of a sudden the water started to pour through the handle hence lost the pressure of the water. Is this a rubber washer issue or the gun needs replacing or simpler than that. To be honest although I have had the washer for about 3/4 years now It is hardly used. Also can I fix it and where would I purchase the allen key to replace. Thanks Brian

I have a G2500VH pressure washer that has started to pulse when the trigger is squeezed. This happens if I use the 0,25, and 40 degree nozzles BUT if I use the one for low pressure(detergent use) it will hold pressure fine. I have changed the unloader valve, checked all the valves and seals ad they seem to be fine. What could be the problem?

I have a Karcher K3.48M electric pressure washer which used to shut off when you weren't using the cleaning wand. This no longer happens and there is alot of water running out of the bottom of the unit. (This didn't used ot be the case) I expect a leak somewhere inside the unit, but I'm wondering even more if there is a pressure switch which has failed that cased the leak. In other words, if I find and repair the leak and there is a failed pressure switch, it will likely only break again. I can'

My Karcher K3.48M pressure washer remains in the low pressure mode even when I return the pressure nozzle to the high pressure position. How can this be corrected. The pump seems to build up the pressure because when I release the handle the pump motor stops. This is a fairly new pump which was purchased in the latter part of last year(2010). Could this have been caused by the detergent I have been using which is an automotive shampoo? Please help I love this washer and for the times that I u

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

Hi. I'm scratch building a pressure washer using a Comet BXD2831G pump. If I don't plan on using any type of detergent, is it OK (or manditory) to plug the detergent intake to keep it from sucking air? I would use a short piece of hose over the intake with a screw in the opposite end. Also, is it possible to set the pressure by ear? If so, what should I listen for? Thanks for your help!


No need to plug the injector because under pressure (internal force/pressure) keeps valve shut. It only opens when large nozzle (black tip) is used lowering internal pressure causing siphon effect. Some chemical injectors have a thumbwheel ... Comet GXD2527G Pressure Washer Pump
