How to Identify and Fix Common Gardening Problems ?

We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :

When the power washer does not turn on, it is either due to no water flow or no electricity going to the power washer. In other words, either a water flow or an electrical problem. The first area to check with the customer is water flow. There must be water flow through the system for the unit to turn on.
PLEASE NOTE: You should always press the RESET button on the GFCI before using the pressure washer.
Begin isolating the problem by hooking a water hose to the washer`s inlet and turning it on. If water flows out the outlet, you know water is cycling through. If not, chances are your inlet filter is clogged. Remove and clean it, and you should be good to go.
The Fuse. If the pressure washer does not start, then the first thing to check is the fuse in the plug. The reading you`re looking for is the same as it would be when connecting the two probes of the multimeter together (as you can see in the example of this video, this fuse is actually fine).
It Can Harm The Unit

Without water to cool and lubricate it, the pump will work harder than it should, causing it to wear down quickly. This can happen even with just a few seconds of running the pressure washer without the water being turned on.

Here`s how it works, devices from the Home & Garden range can be repaired in our repair centres. Machines within their warranty period are repaired free of charge subject to our Home & Garden terms and conditions.
Some pressure switches have to be reset when the machine is moved or before the machine`s first use. To do this put two litres of water inside the drum set the machine to a drain cycle and it will automatically reset the machine.

My Z5426 won’t start. When I pull out the choke and turn the key, gas starts leaking out of the exhaust system just before it gets to the muffler. Last time it did start, it ran really rough. So, I turn off the engine and then tried to restart and that’s when I noticed the fuel leak.
ANSWER : Maybe bad fuel, fuel line leaking, flooding of the carburetor, since it did start and ran rough I am assuming that the gas was left set and more then likely this gummed up the carburetor, you will have to clean/rebuild it. If you have a can of carburetor clean you may be able to spray that into there and clean it up, I would not choke it to start it as it sounds like it got/is flooded/ing. Good Luck Tim

I have a Karcher 3.49M purchased 8/2/09. Using the washer I inadvertently turned on after changing hoses, but forgot to turn water back on; this activation lasted only a couple of minutes before I realized there was no water. Now the unit makes a humming noise and does not turn on.
Can this be corrected, or do you believe the motor is burned up? I tried various electrical outlets and resetting etc. but to no avail. Thank you.
ANSWER : Normally when you dry run a machine you damage the pump so it would probably need changing. The motor might be Ok but for you to fix it you will need to take it to a Karcher dealer/service center.

From experiance it sometimes can be more cost efficient to purchase a new Karcher machine and get the 12 month warranty than spending money on an older machine.
