When using the sweep nozzle (yellow tip), the pressure starts and stops but the machine works fine when using the circluar nozzle(red)

Soap Injector Not Working Properly
When a soap injector is not working properly, the problem is generally fairly easy to isolate. Check the following:
1. If you have interchangeable tips, make sure the Black, soap tip is installed. Soap injectors will not work when high pressure nozzles are installed.
2. Be sure that the soap injector valve is turned on, and turn selector valve to desired setting.
3. A piece of debris may be caught in the injector valve, injector ball valve, or orifice. Disassemble and clean the injector.
4. If you have an adjustable nozzle, be sure it is in the low pressure position (away from the gun) to draw soap.

Interchangeable Tips
Your machine is supplied with either interchangeable tips or a multi-reg. Your machine is supplied with interchangeable spray tips. The black tip lowers your pressure and draws chemical. The other tips are for high pressure rinse at different spray angles. Red is 0 degree, yellow is 15 degree, green is 25 degree and white is 40 degree. The yellow tip is used for most standard applications. Be sure the quick coupler is fully engaged before pulling the trigger gun. Failure to do may result in the tip becoming a projectile and may be lost or damage to property or persons may occur.

blockage in the wand nozzle jet

do you mean pressure on and off with the hp tips and smooth and steady with chemical tip?

The clear hose with a filter on the end is a cleaning solution pick-up tube. It attaches to the washer near where the pressure hose attaches to the machine. There is ususally a barbed hose fitting for it to slip over. If you are using the black, low pressure, soap tip the hose will allow the machine to pick up cleaning solution either from a bucket or straight from the bottle, mix it in the water and spray it out on whatever you are cleaning. It will not work if you have one of the high pressure tips on the wand. They are usually red, yellow, white or green.

Remove the tip and pull the wand trigger without the tip in. If water comes out then your tip is clogged. Clean the tip and reinstall. Or try a different tip.

Its also possible that there is a kink in the supply hose to the unit.

Try these first, it should solve the problem about 90% of the time

Hi,

You need to clean the print head and insert the cartridge and check, whether it is working at fine because a dirty printer header will not allow the right formulation of the basic cyan, magenta, and yellow to print and comes up with the yellow color and not red.
If you still face the problem after cleaning print head then you need to check for a clogged nozzle. Clean the nozzle and then try printing it will work fine now.
To clean the print head from the Utility section found in the printer driver, clean the print heads by performing a head cleaning followed by printing a nozzle check pattern. Furthermore, you can clean the print head by Using a cotton Q-Tip & Isopropyl Alcohol and gently rub the print head with alcohol.

Hope this helps.

If you still have any queries, please feel free to ask us.

that is sure signal of insufficient water supply!

try easy solution first:
make sure that your mains is fully open, that tap on whihc hose is hook up is fully open and hose is of "decent" diameter to allow sufficient flow.

if above solution do not work then you need to make another, more difficult arrangement:
prepare 20litres pressure tank with inlet connected to mains and outlet by short hose to power washer, fill it with water from mains, keep it under mains pressure and use karcher power washer normaly. this will solve water supply problem. twenty litres will last about 2min, because it is re-filled, under standard pressure therefore it will last about 3min...

third possibility is to stop washing...

if you find my advice helpfull, please do not hesitate to left the comment and vote for me, thanx!

The reason it stops spraying might be a clogged gun, hose or nozzle-tip.
The reason for pressure buildup killing the engine might be a stuck unloader valve in the pump.

While you are checking each component of the "output" side, spray some penetrating lube into the "input" side of the pump (where the garden hose connects) and let it be working on the unloader valve.

Fix the spraying problem first:
Start at the nozzle and verify that it is open by using low-pressure air. Clean or replace as needed. Next check the hose (with nozzle and gun unhooked) and finally the gun/trigger mechanism.
All must be clear and open to perform correctly.

Next, pour a few ounces of power steering fluid (or similarly LIGHT oil) into the garden hose, attach it to the pump and turn on the water supply.

Leave the "output" hose, gun, etc. UNHOOKED and point the output port of the pump (where the high-pressure hose connects) towards a vacant, safe area.
Startup the engine and allow the oil in the garden hose to work its way thru. (About 1 -3 minutes of run-time.) Shut it down and attach the high-pressure hose.
Hope this solves the problem!

the red button is just for the warning label. Did you pull the nozzle down. This nozzle is an adjustable nozzle. You push it in and this is for the soap injector and you pull it out for the pressure. If you have done this, then you may need to replace the nozzle. You can even put a quick diconnect on the end and use the small tips you can buy local or replace with the same type nozzle.
Also check to see if there is something blocking the hole.

Try using warn distilled water and Q-tips to gently clean the area where the ink cartridge and the carriage mate up. You may have dried old ink in there which is clogging the print nozzles. Allow to air dry, reinstall cartidges, start machine and let it go through its cleaning cycle. Also check www.hp.com. Hope this helps.
