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

I have a McCulloch FH160B power washer and it no longer builds up pressure. I haven't used this very much at all. I tore it apart and cleaned everything I could find. When i pull the trigger for the spray nozzle, I get line water pressure. When I release the trigger, the power washer sounds like it starts to build up pressure. When this was working correctly, the pump would shut off when the trigger was released. Any suggestions?

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

Campbell Hausfield Pressure washer model 1549. After a few years of storage, I cannot prevent the powerful spray leaking from the connection between the Gun and the Lance. I replaced the O-Ring, and tried other means unsuccessfully. Spray from the joint is almost as powerful as spray from the lance nozzle. The Briggs and Stratton engine has been cleaned and operates well. The pump operates well. But the lance connection refuses to seal.


Hello,Most likely, the housing has split and seal is not being made. There is a chance that the hose is leaking where the fitting is crimped on (my experience, but different pressure washer). Are you able to see a leak when turned off b ... Campbell Hausfeld Pressure Washers

I have a Siemens dishwasher serie IQ which has had water damage. There has been water pressure on the drain tube. Probably the mashine has been partly filled with drain water. Now it can start and pump out the water, but it never starts any washing program. Well it starts and the time left (e.g. 15 min on the shortest program) is displayed. But then it does not start to wash or count down. Any idea what is wrong or broken? Anyway I can repair or reset the dishwasher?

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

The pump doesn't seem to put out enough water pressure to turn the various revolving heads/nozzles in the washer - all washing heads are operable (ie unblocked) while the S shaped nozzle at the base and the small round nozzle at the top/ceiling of the cabinet do revolve slightly or slowly - but the two main nozzles spout water but not enough to revolve Is this a defective pump or a partially blocked pump ? - or something else - I have checked everything else and they appear to be functioning

My karcher hds 745 is running but just won't build up pressure, this occurred after a really cold few weeks this winter and I hadn't put anti-freeze through the machine to winterize it. There's no water coming from the bottom of the machine when it's running as i've read that if the pump seals are faulty water will escape from the pump etc. The machine motor runs ok but no pressure is acheived on the gauge whatsoever. Any help would be appreciated. Thanks in advance Paul.

I have a Generac pressure washer, model #01450-0, with a Honda 5hp motor. The motor runs fine, but the pressure hose pulsates as if the pump is intermittently making pressure, and the pressure out of the sprayer is about half of what it should be. A friend suggested replacing the seals in the unloader. I bought an unloader kit, replaced everything and it still runs the same. It will build a small amount of pressure, spray for a few seconds, then the pressure dropps to almost nothing. Any help ap
