Top 20 Northstar Pressure Washer 3000 PSI Questions & Answers

Sounds like the trigger is not closing, best to strip it down and check operation. Probably siezed in the open position.

Cannot. Ensure u have a 3000psi wand.

If it connect to the outlet pipe/lance then it operates on SUCTION similar to blowing across the top of a beer bottle to make a noise. If thats the case it is a matter of blockage and ventilation of the soap bottle to allow air to enter as the soap is sucked out by the water flow.

Remove the cage and see if the spring has jammed.

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

do you have spark?try starting fluid that will tell you if its a fuel problem

whenever i had that problem there was insufficient water pressure from the house and the pressure washer would run like ****, or did you try to adjust the pressure regulater to get more pressure

You will need to remove the carburetor and clean. Be sure to clean the high speed jet. This jet is the bolt that holds the fuel bowl on. Remove and clean the small holes in the sides of bolt. You will need a small piece of wire or bread tie just remove the outer covering and run this through the holes. Some have a hole in the bottom and smaller hole in the threads towards the top. Clean with carburetor cleaner and blow with compressed air. Try cleaning the jet first and if this doesn't work then clean and rebuild entire carb. Hope this helps.

Have a look at these tips for getting lawnmowers to start. The troubleshooting procedure is the same for all small petrol engines.

Your problem is going to be with the brass fitting with the spring that you have discribed. This fitting is called an unloader valve, this valve is designed to by-pass the pressure that the pump has built up so you don't damage the pump when you release the trigger. There should be a nut on the end of this valve try turning it in some if this doesn't work try turning it out. It is usually set at the factory but sometimes they either don't get set or they are bad. You also could try to remove and clean. re-install with a light coat of white lithium grease. Hope this helps, let me know how you make out.

If this hole has threads then it might be the soap inlet. If water is shooting out under pressure you may have an obstruction in the hose/handle. Try removing the hose and running the washer and see if the water flows out the connection. If the hose ends up being the problem a visual inspection and cleaning of all inlets and the handle should clear it.

If the water coming out of the hole is low/tap line pressure then I think your bypass *(or unloader) valve is stuck in the bypass position.

A stuck unloader just needs to be unstuck and lightly cleaned. A light coating of silicon grease wouldnt hurt either!

Get the manual for this pump and see how to open/remove the unloader valve.

Hi, the carby needs to be disassembled and all jets blown out. Regards Phil.

the short answer is "no" and I have to ask, why would you want to, if you are thinking that you could use it to provide high pressure air to blow stuff off your deck, it won't work, the pump requires liquid in order to get enough pressure to push the water at high pressure

Usually, they use universal tractor transmission fluid (available at any tractor supply, but I have boughr it at Wal-Mart. Here's a link that will take you to available models and manuals:

Yes. Both brands use M22 (22MM) hose fittings. You will need to check that the Karcher hose is rated to a high enough pressure for your washer, especially if it is a thermoplastic hose as they tend to be rated for 2500 PSI.

Make sure the tube is not kinked and the port and suction nipple are clear. Try back flushing once or twice. Good luck!

i would change the oil every 100 hours or six months in the engine.
and would change the oil in the pump every 12 months.
to change the engine oil,look for a 12mm or 13mm bolt at the base of the motor.
it should be at the front of the engine.undo bolt & drain oil into a container.
tighten bolt up & fill engine with new oil.
