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 :

If the pull rope doesn`t retract, it`s likely that the spring inside the recoil starter is broken. The recoil starter can also fail to engage the engine when the rope is pulled. Replace the recoil starter if the spring breaks or if the recoil starter won`t engage the engine.
If you cannot shut off the water from the trigger wand and there are no known issues with the unloader valve, there is likely an issue with the wand itself. The trigger wand has a mechanism inside of it so that when the trigger is released, the flow of water is blocked.
When an unloader valve gets stuck closed, the result is often a stalling of the engine and leaking of the spray tip. This occurs because the unloader valve cannot release the pressure as it should, even when the trigger is depressed.
The problem may be in the recoil starter itself. A tangled coil of rope or a broken spring may be the problem. In many cases the recoil starter is easily replaced as a single assembly. DO NOT attempt do take the starter apart.
Without an unloader valve, the water pressure continues to build up in the nozzle, potentially causing a very unsafe situation. The increase in pressure – without an unloader valve to regulate it – could cause the water pressure to go over the PSI limit, potentially damaging your pressure washer`s pump.
PLEASE NOTE: You should always press the RESET button on the GFCI before using the pressure washer.
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.
DON`T Let the Machine Run Too Long Without Pulling the Trigger. Pressure washers operate under pressure, and that pressure needs to be released by pulling the trigger. If you let the machine run for two minutes or longer without spraying water, then you could damage the pump.

Soap feed The soap feed hose on my Karcher 2650 does not suck up the soap into the washer. I pulled off the connector piece that the hose is connected to. I can blow through the hose. There is a little metal finger thing that you can tell pushes up into place when the water pressure is high. It seems like it is supposed to drop down and allow some soap through when the water is running. I found a loose(attached to nothing) gasket, looks like a little donut. It was just free floating in there. I’m thinking it may go over the finger mechanism. I just put it back on top of the finger, like a halo and put the screw in piece back in. Anyway, if you know, let me know how all that goes together.

I have a 2000 psi simonize gas fired..Can.t get any water when pump is running. I took the. water pressure hose off on unit and still no water
ANSWER : If the unit has been stored you need to remove the bottom three plugs on inlet side of pump head and simply free the checkvalves that are in closed position needle nose recommended and small screwdriver to pry them open this is caused by the impurites in water that dry up and seals the head and disc together:):)

1750 psi Electric Pressure Washer: My pressure washer is losing pressure and is pulsa…
ANSWER : If the pressure washer is pulsating then that is a sign of check valve failure. You may be able to clean of replace the check valves. Replacing the head is the wrong way to go. This is completely unnecessary. If you can tell me the model number of your pressure washer then I can assist you better in pointing you in the right direction.
