Excell Power Washers are powered by Honda engines. They are all at least 50 times more powerful than the standard garden hose and have multi-adjustable spray heads. On average, they can pump 2.5 gallons per minute. No matter which Excell model you own, you are bound to run into some troubles eventually. Try troubleshooting the problems on your own before you spend money at a repair center.
If your Excell Power Washer will not start, make sure you have enough fuel in it. Also, pressure can build up after you have pulled the recoil starter twice, so squeeze the trigger on the gun to relieve that pressure. Make sure the choke lever is not in the "No Choke" position and that the spark plug wire is attached.
If your power washer is producing no, or low, pressure, make sure your wand is set to high pressure. Your owner's manual will have instructions for how to use the wand. Make sure your water supply is at least five gallons per minute at 20 PSI, and that there are no leaks in the high-pressure hose. You can clean any obstructions out of the nozzle with a paper clip, if you don't have a nozzle-cleaning tool. Also, pour water into the nozzle end to flush out debris. A clogged water filter screen can reduce pressure, as can a defective E-Z start valve. You will need to see a service center to have the start valve replaced, if you determine that is your problem.
If your unit will not draw any chemicals, the wand may not be in the low-pressure setting. In addition, you may have a clogged chemical filter. If the chemical screen is not in the chemical, it will not be able to draw them. Make sure it is fully submerged. Dilute the chemical if it is too thick, so that it has the consistency of water. Ensure that the pressure hose is not too long. If there is a chemical build up in the chemical injector, you will need to have the parts cleaned or replaced at a service center.
