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 :
Water leaking from a loose connection can cause the unit to cycle on and off. Verify if the pressure hose has an O-ring at the connection. If missing, this will also cause the unit to cycle on and off. While the unit is running look for any water leaks that may cause the unit to turn back on.
A pressure washer stalling when the trigger is pulled is mostly due to a faulty unloader valve, O-rings, pressure washer trigger, or a too-high setting of the unloader valve. What is this? The root cause of a stalling issue is usually a problematic unloader valve.
It damages your equipment, causing you down time and costly repairs. Hard water is particularly damaging to pressure washers, and can shorten their life expectancy. Scaly deposits form inside the pressure washer heating coils, reducing the flow of water and minimizing the heat exchange.
If the spark arrestor is dirty or damaged, it can cause the engine to stall. To clean the spark arrestor, you will need to remove it from the pressure washer and use a wire brush to remove any build-up. Once the spark arrestor is clean, you can reattach it and try starting the power washer again.
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.
Water leaks and inconsistent behavior are also signs of a potential failure in the near future. González: The typical signal when there is an unloader malfunction is a reduction of flow through the nozzle, which results in pressure loss. Dean: Typical symptom of an unloader failure is a sudden smooth pressure loss.
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.
What Is the Unloader Valve? A compressor unloader valve is a small part, typically measuring approximately 4-5 inches in length and width. It performs the critical function of releasing trapped air inside the tank, enabling the motor to restart.
These include an incoming power problem, a damaged power cord, a malfunctioning door lid switch or lock, a defective user control board or timer, a broken drive belt, or a faulty or obstructed drain pump.
One of the common problems that occurs in a car wash, is the electric motor burning out in the high pressure cleaner and while there are numerous factors that can contribute to this, one of the more predominant reasons is the following.
The easiest way to tell if your engine is flooded with gas is to remove the spark plug. If it`s wet, it`s flooded and you`ll need to let the cylinder dry out before trying to restart. Compressed air can help speed up the process.
If the spark arrestor is dirty or damaged, it can cause the engine to stall. To clean the spark arrestor, you will need to remove it from the pressure washer and use a wire brush to remove any build-up. Once the spark arrestor is clean, you can reattach it and try starting the power washer again.
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.

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.

I have a Coleman 2750 power washer that just idels when you pull the handle. Why is it not reving up with pressure?
ANSWER : Possibly has leaking seals or there is a blockage in the gun or hose. remove the hose first and see if it is putting out enough water.

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.

My Simpson Water Shotgun shuts down about a minute into the wash
ANSWER : Have you checked the oil level? Some engines have a sensor that shuts it down if the oil is too low

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.

My coleman powermate 2750 pressure washer locks the engine up when the trigger is pulled. after a few seconds you can restart it.it comes up to good pressure but kills the motor. Some have told me they thought it was teh pump, but the sprays a little. I would think if the pump was bad it wouldn’t spray at all? Comments?
ANSWER : All i can say is its not a good mechine I owen and repair washers and pumps and use them in line of business thats all i can tell you sorry

Power washer starts, water to washer on but no water pressure come out the hose
ANSWER : This with the engine running? If so there eigther is a restriction in the main water feed or the pump is damaged or possibly needs to be rebuilt. Did you know you can never start the mechine with the water hooked up and on full and you should trigger the gun to force the air from the water pump before you ever start the engine. Is it a mi-t-m pump or a cat pump. The mi-t-m pumps have a problem with the plastic cages that hold the valves braking and getting stuck between the valve and the valve seat if you take the caps off the pump you can pull the peice out and the mechine will work again. The cat pumps have cremic pistion and if over heater need to be rebuilt but is a vastly better pump and if maintained wil last 25 to 30 years under heavy use
