Nozzle blocked nozzle does not spray

Check the spray arm nozzles for being blocked. The end nozzles, spin the arms around. The upper holes wash the dishes. If your model has a top spray arm, the nozzles will be underneath to direct the water down.

check the nozzle isnt blocked easiest way to do this is remove pipe from lance handle and see if it fires water at pressure when lance isnt attached if it does fire water at pressure then your spray nozzle is blocked or turned off at the nozzle the nozzle can sometimes spin to far round and close

use a tiny needle to cleardirt on the holes on the sprayand nozzles you can even adjust the nozzles using the very same neddle by moving the needle to the correct direction that you like it to spray . Pull the hose off the nozzle and check water pressure and see if fluid comes outt, the line may loose pressure or blocked, not the nozzle.
If the line is good than revert back to adjust the spray nozzle using the niddle by putting niddle in the holes of the nozzle and adjust by moving it up and down or left to right it must work..

by using a pin to clear the nozzle all you are doing is pushing the obstruction back into the hose which immediately comes back into the nozzle blocking it again. Take off the hose to the nozzle and use compressed air to blow the obstruction out of the system

blocked pressure hose or blocked nozzle at the end of the wand
it is controlled by a pressure relief regulator which quite often plays up.

If you can hear the washer bottle motor then you know its not an electrical problem, if you can see the fluid in the lines then the best thing to do would at each connection in the hose disconnect the line and operate the washes and see if the fluid comes out (also pay attention to pressure) do this until you reach the washer nozzles. The nozzles could be blocked. now you might say that you put new lines on so the nozzles shouldn't be blocked well if you think of it the previous hose could have been partly bocked thereby stopping any **** that is at the filter on the washer motor going anywhere(most modern cars have filters on the washer motors) So by putting new lines on you have allowed the **** at the motor travel all the way to the nozzles letting them get blocked.
Hope this helps.

when you pull the trigger can u see the needle moving backward? if so, then it's either the paint is too thick compare to the nozzle size or the passage for paint is blocked. try to take the nozzle, needle and the cup off and give it a good clean!

First try to clean out the squirter nozzles.Take a very small wire, sometimes a staple works great, and stick it into the nozzle to clear any debris.Then try to spray it again.If this didn't solve the problem and the debris is cleared, then you either have a weak or blocked pump, which is located on the washer reservoir itself.Hope I could help!!! Rate me accordingly!! Thanks!

I have a similar problem and `phoned Bissell support. They told me that no spray is either a failed drive belt or a failed pump. I suggest you remove the belt access cover and see if the belt is intact; if so rotate the pump using finger pressure - it should rotate easily with no unusual noises.

If this is all OK, fill the bucket and the mix bottle with warm, clean water. Turn the machine on and with the handle upright press and hold the trigger for about 2 minutes. Hopefully you should see a spray and both the bucket and bottle will reduce in volume. If not you have either a blockage in one of the tubes, the trigger valve needs adjustment or, worst case, the pump has failed.

Hope this helps.

In general, pressure washers will draw detergent from the reservoir only when the spray nozzle is set to low pressure. At high pressure a non-return valve closes to prevent water flowing back in to the reservoir. If you've got the spray nozzle set to low pressure and still have the problem, it may be that the spray nozzle is partially blocked - you can try clearing it with a length of wire.  Failing that, the non-return valve is probably stuck (and that may need professional attention).
