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 :

There could be small leaks, holes, or tears in your garden hose or high-pressure hose that are causing your pressure washer to lose pressure when you pull the trigger. If you find leaks, plug the holes or replace the hose, which should solve your pressure issues.
If your engine will not idle and is continuously stalling, a bad unloader valve may be the cause. The unloader valve is located on the top of the power washers pump system, and occasionally has a black handle on its top.
Carburetor problems: A common cause of idling up and down is a dirty or clogged carburetor. The carburetor is responsible for mixing fuel and air to create a combustible mixture. If the carburetor is dirty or clogged, it can cause the engine to run poorly and idle up and down.
An idle down controller for pressure washers is responsive to the drop in pressure at the pump outlet. The controller includes a sensor disposed in the pump outlet manifold. When the fluid is being bypassed, the manifold pressure drop is communicated to an actuator.
How Do I Tell If My Unloader Valve is Bad? In most occurrences, the first symptom of an unloader valve going bad is no pressure from the wand when the trigger is pressed. This happens when the unloader valve gets stuck open and does not allow water to enter the hose and trigger.
For this reason you should not let your pressure washer idle, not spraying water for more than a few minutes. Without cooling the pump head the temperature will begin to climb to 200+ degrees. When it gets that hot, water seals and o-rings soften and wear quickly. Valves can be distorted and warp.
Idle pressure is meant as the pressure of the non-flowing (idling) gas. The connected gas devices are not in operation. The contrary of idle pressure is flow pressure (gas pressure of streaming/flowing gas when one or several connected devices are in operation.
Often times, a machine producing low pressure will surge, cycle on and off, or continue to run. This typically indicates that the machine is losing pressure somewhere, such as a leak in one of the lines or inside the case of the machine.
Replace leaking, punctured or rusted hoses. Clean your drain pump every three months to avoid clogging. You might be using more detergent than necessary. In this case, your washing machine will stop and try to absorb the excess foam in its drum.

This pressure washer will continue to build pressure when you let off the trigger. I have replaced the hose 3 times because the pump continues to pump until it blows the hose. The pump will not stop pumping!
ANSWER : You have a defective pressure release valve or someone has misadjusted.

My Honda 2600 psi power washer will not pull to start. It was running great then I allowed the neighbor to borrow it. He ran the washer till it was out of gas and proceeded to refuel and at this point it would no longer start. The pull cord is out about 4-6 inches out and I am concerned about taking the casing off myself.

Fearing that it may throw more off on the unit. If i take the casing off are there any spring loaded parts that will dismount?

What should I do? Spark Plug? Turn wrenches?

Please let me know

ANSWER : You should be fine to take the recoil off, there shouldn’t be anything that shoots out at you. You might want to check the oil level on the engine, many of the Honda engines won’t start unless there is enough oil in them. If your oil level is fine, check to make sure that your motor is getting spark.

Power washer won't start – Briggs & Stratton Power Products 1539 Pressure Washer
ANSWER : Have you checked for spark? You can remove the plug, touch it against the block and crank it and see if you have any spark (best done in as dark a place as possible). If you don’t have spark, start by replacing the plug.

If you have spark, you can spray some starter fluid or gas into the cylinder, replace the plug and try to start it. If it runs for a few second, then you have fuel flow problem (dirty carb or filter, etc.).

Hope these basic tips get you going in the right direction.

WATER COMING OUT AT BOTTOM OF WASHER – Karcher K2.26 Electric Power Washer
ANSWER : Dear Sir,
In this case the seals surrounding the pistons (3 in number)..are faulty.
You can open the cover first ( by using a TORX T15 screw driver). Start machine in this way with all attached…( never run a power washer with out water and never store a power washer with pressure in it). When you start machine with out cover you can more easely see from where water is coming out. Mostly the case will be that water is coming out from between the head and the bottom part of machine. If water went into the bottom part…then the oil is ruined also.
So this case needs that all seals to be changed. One must inspect the pistons….because if the pistons are scrathed and pitted…then it is useless to put new seals. Thus new pistons must be put with new seals…and other gaskets renewed.

The pull cord will not pull..I can’t start the engine. What can I do?
ANSWER : Remove the spark plug and see if it will then turn over. If it does then the motor is not seized or has water or fluid it is trying to compress.If the above lets it turn over freely the problem lies with the cord being trapped on the pully that is spring loaded.This task is better investigated by someone with experience to avoid losing parts and not beoing able to reassemble.
