2500 PSI Pressure Washer
Hi I have a Honda 1600 psi pressure washer which starts just fine with the lance trigger pulled and will stay working as long as I keep the trigger pulled . On release the washer starts to sound like its labouring and then cuts out. It will restart immediately and keep going again until the trigger is let go again. Anybody any ideas thanks, Brian
Experienced gardeners share their insights in answering this question :
You most likely need to set your valve clearances. If it is hard to
pull over or the recoil snaps back after starting your valves need to
be set for sure. This may not be the entire problem but it is a good
start. Also change the spark plug, a bad plug will cause odd problems
and is too cheap not to eliminate as a source. In addition check your
fuel, pour a little out into a white container (I like spray paint can
caps for this) and look at the color. If it is yellow to orange it is
bad. You can pour it into you car, the car electronic sensors will
compinsate for it quality but a small engine can’t. Use a NGK BP6ES or
BPR6ES plug.You need:Feeler gages10mm open end wrench14mm open end wrench1 long shaft screw driver or rod1 spark plug socket and ratchetRemove
the spark plug and the valve cover. Pull the recoil over slowly until
the intake valve opens (intake is closes to the carb and it will go
down when it opens). Now put your long screwdrive down the spark plug
hole. Slow pull the engine over until the screwdriver handle is at it
highest point, this is top dead center. It may take a few attempts. Now
check your valve clearance between the rockers and the top of the
valve. The intake should be .006 and the exhaust .008, both can be +/-
.001. To adjust: hold the large nut with the 14mm then loosen the small
one with the 10mm. Lefty loosey. Now turn your large nut until you get
the correct setting and then tighten the small one the lock it in. It
may take a few attempts and alway reverify your setting after you lock
it down. Once done, find top dead center again and reverify. Now your
valves are set.

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 this is a gas powered pressure washer, then the pump is not going into by-pass mode and the pressure build up is overloading the engine causing it to shut down.
Low Engine Oil Shut off
Many brands, like Honda, have a low-engine oil-shut-off feature. The pressure washer starts normally, runs for a few seconds, and then dies. Solution: Check that your washer has enough oil in it. It is critical to check oil levels before starting your washer.
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.
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.
Some of the most common faults that will make your washer stop mid cycle include thermostat failure, problems filling up with water for the rinse cycle, or even pump problems that prevent your washer from draining. One thing that you can check yourself is the lid switch.
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.
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.
And when a PRV fails, it can lead to an explosion. Damaged equipment, disrupted work flow, and even injury may result. Why take that risk when you can easily tell whether or not your pressure relief valve needs replacing or repair.
The difference between regulator and unloader occurs when flow downstream is stopped. A regulator redirects flow through the bypass port, maintaining full system pressure. An unloader valve closes the fluid passageway and traps pressure in the discharge line.
A trapped pressure unloader valve opens when there is an increase in pressure, so when the trigger on the gun is released (open) the pressure increases and opens the unloader valve sending the water back to a holding tank or back to the inlet side of the pump.
Common check valve problems include noise (water hammer), vibration/chattering, reverse flow, sticking, leakage, missing internals, component wear or damage. However, it is worth mentioning that normally the real cause is the wrong size, spring, and/or style for the check valve application.
By turning the adjustment screw counterclockwise until the pressure gauge is below the desired setting, you will loosen the jam nut and reduce the spring tension. You will then need to retighten the adjustment screw tension by turning the adjustment screw clockwise to the desired setting.
Unloading valves are used in hydraulic circuits, these valves would stop or remove the flow of the pump back to the tank when the machine is not operating. So by this reduction of heat and energy saving can be achieved because the prime mover load is reduced.
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.
If the drum stops spinning mid-cycle, try stopping the machine, draining the water and rearranging the laundry. You might be using too much detergent or an inappropriate type for your appliance. In this case, your washing machine will stop the spinning cycle and try to absorb the excess foam in its drum.
Without an unloader valve, the pressure across the suction line in a conventional compressor may drop too much, which could cause the compressor to cycle on and off repeatedly in order to meet fluctuating load conditions.
Perhaps the most obvious sign of a compressor issue is poor air conditioning performance. If you notice your cabin feeling warmer than usual or your air conditioner is blowing warm air, you know that your system is experiencing some troubles.
The damage may not always be instantaneous, but the more you start your pressure washer without water, the more you risk ruining your machine. Take note that if either the pump or the motor fails, you won`t be able to use your pressure washer.
When the air pressure inside the compressor`s tank reaches the pressure switch`s cut out pressure (the point when air is no longer delivered), the switch automatically trips off and interrupts the power supply to the motor. This process causes the unloader valve to open and vent the accumulated air.
Fail Open (FO) means that when there is a loss of signal, the valve opens. If you are using your valve in a back pressure application, such as holding pressure on a separator, a fail open valve would allow you to prevent excessive pressure build up on the upstream side of the valve in the event of a failure.
Many of the failures in a hydraulic system show similar symptoms: a gradual or sudden loss of high pressure, resulting in loss of power or loss of speed in the cylinders. The cylinder(s) may not move at all, or if they do they may move too slowly or may stall under light loads.
Among the types of pressure regulators are back pressure, vacuum pressure, differential pressure, pressure-reducing and regulators for specific kinds of fluids like oil and fuel.
There are three types of Switching voltage regulators: Step up, Step down, and Inverter voltage regulators.
Pressure regulators are mechanical valves that use feedback to control pressure in both pneumatic and hydraulic systems. There are basically two types of regulators: one regulates upstream pressure (back-pressure regulators) and the other regulates downstream pressure (pressure-reducing regulators).

Need help in getting Honda engine on NorthStar pressure washer to run.
ANSWER : Could be low water pressure I have found.Also, I purchased a can of “stuff” at Lowes today which allows you to circulate a liquid substance which lubricates the pressure pump….the pump could be frozen up…I have a rotating nozzle which I bought…and it had frozen up…this stuff works

Honda powwer boss 3000-whenyoupull the handale to spray it kills the engine
ANSWER : Sounds like the unloader (regulator). Try removing the nozzle, the pull the trigger with the engine running. If motor is still running then it could be the Unloader malfunctioning. If you require a new one try a bypass system for the unloader. The bypass will help save the life of the unloader.

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.

My honda gx110 water pump has been sitting outside for a year and now wont start.. I’ve bled it, changed the oil and refuelled, still no success! (plug seems ok) any suggestions? cheers
ANSWER : There is a very good possibility that corrosion has locked up the float. I would try removing the cover/bowl and make sure the float isn’t stuck. With all of the other things you’ve done this is my best guess.
Good luck!
