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.


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 ... Karcher K2.26 Electric Power Washer

The Hom Model No. 308653045 gas-operated cold-water pressure washer has a spring-loaded control on it and I am assuming that this control regulates the output pressure of the water from the pump . . . for example, 1500 psi to 2700 psi. Is it correct to assume that this control regulates the output pressure of the pump. If the control is a pressure regulator, how does one use it and, EVEN MORE IMPORTANT, can one under-adjust or over-adjust the control to a point where THE CONTROL OR THE PUM

No pressure Gas powered pump is a radial type from DeVilbiss. There is very low pressure, although there is some pulsing from the pumping action. There are no leaks and the supply pressure is good. Pump pistons are in good condition. They seem to be pumping when I had it disassembled and operated by hand. I suspect it is something in the bypass or unloader. Or it may be in the ''easy start'' assembly which I assume reduces backpressure on the pump when starting the engine. Pump has a temperatu

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

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?

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

Pressure gauge needle stays in max position running or not. otherwise pressure washer operates normally.


Pressure gauge is probably "sprung". Unless it bothers you, ignore it.

Noisy pump This is supposedly the quietest washing machine. It is until the pump comes into operation. It pumps incessantly for up to ten minutes before the spin operates and it is extremely noisy. I have had an Hotpoint engineer visit and he brusquely said that this is normal. I wouldn't have purchased it if I had known this. My previous Zanussi was much better. Was the engineer correct?


It depends on the design, the way it is mounted on the machine matters a lot.Sometimes pump makes noise due air trapping. Check your water flow. Add 10 liters of water in the chamber direct and close the door. start the machine in usual w ... Dishwashers

The top drawer of my fisher paykel dishwasher stops during the cycle and shows an icon of a tap with a line threw it (assume that means no or low water pressure). the bottom works fine so I assume water pressure is not the issue; is there a sensor that could be bad? Also, I did switch the controllers between drawers (good instructions on the fisherpaykelparts.net website) but the problem stayed with the drawer, ruling out the controller.

I just bought a used Kenmore standalone dishwasher and ran it for the first time. The dishes on the top did not get clean and the soap did not come out of the closed soup dish. at one point I took a shower and was wondering if that might have influenced the water pressure enough to cause the problem. Is the soap supposed to open during the wash and could the poor water pressure prevent the top shelf from getting properly washed?


The inlet filter is probably clogged. Try letting it fill up. Open the door to stop it right after it starts to wash Pour a gallon or two of hot water in and see it it works better Stop and do this everytime it goes to fill up. If the door opens ... Dishwashers
