Pressure washers & generators

Pressure washer nozzle is clogged

A clogged nozzle tip is one of the most common and easiest pressure washer problems to fix, usually caused by dirt, sand, or mineral deposits narrowing the small orifice.

Symptoms

  • Spray pattern is uneven or off to one side
  • Reduced pressure that improves with a different tip
  • Spray sputters or dribbles instead of a clean jet
  • No water comes out of the wand at all

Likely causes

  • CommonDirt or debris lodged in the tipEspecially common after using the washer near a dirty driveway or garden bed.
  • PossibleMineral or hard-water buildupScale can build up inside the narrow orifice over repeated use with hard tap water.
  • PossibleDebris in the quick-connect fitting, not the tip itselfGrit can lodge where the tip meets the wand, restricting flow even with a clean tip.
  • Less commonWrong tip for the task creating a false 'clog' impressionA very fine-degree tip naturally produces a thin, high-pressure stream that can look 'blocked' compared to a wider tip.

What to do

  1. Turn off the machine and release pressure by squeezing the trigger before touching the nozzle.
  2. Remove the nozzle tip from the wand.
  3. Use the cleaning pin that came with the unit, or a straightened paperclip, to gently poke through the tip's orifice from the spray-exit side.
  4. Rinse the tip under running water, spraying backward through it if possible to flush debris out.
  5. Inspect the quick-connect socket on the wand for lodged debris and clean it out as well.
  6. Reattach the tip and test the spray pattern at low trigger pressure before full use.
  7. If the tip's opening looks worn (oval instead of round) rather than blocked, replace it since a worn tip won't hold pressure.

When to call a pro

This is a simple DIY fix; professional help is rarely needed unless clogging keeps recurring, which may point to a failing inlet filter letting debris through.
