Quick Answer
If your pressure washer lance is not working correctly or is leaking, there are two common issues.
If the spray pattern is not rotating or producing the circular motion, this is usually caused by debris or a stuck ball bearing inside the nozzle.
If the lance is leaking, this is typically due to a small crack or pinhole in the lance body or seam, which will usually require replacement.
Before You Start
Before inspecting or cleaning the lance, make sure:
- The pressure washer is switched off
- The system is fully depressurised
- The lance is disconnected from the spray gun
Always:
- Work in a clean, well-lit area
- Inspect the nozzle and lance carefully for debris
- Avoid forcing tools into the nozzle opening
Important: Do not use a damaged or leaking lance under pressure.
My Spray Pattern Is Not Working
If the lance is not producing the expected circular spray motion, the most likely cause is a stuck internal ball bearing.
How to fix this
- Remove the lance from the spray gun
- Use the nozzle cleaning pin to gently clear the nozzle opening
- Check for any dirt or debris inside the nozzle tip
- Gently rinse the nozzle with clean water
- Reattach and test the spray pattern
Tip: Blockages are often caused by dirt, limescale, or debris from water sources.
My Lance is Leaking
If water is leaking from the lance body or seams, this is usually caused by:
- A small crack in the lance casing
- A pinhole forming along the seam
- Pressure damage over time
This type of damage will normally worsen over time and cannot usually be repaired.
How to Check the Lance
Follow these steps:
1. Inspect the nozzle end
Look for:
- Blockages
- Dirt or grit inside the nozzle
- Damage to the spray opening
2. Inspect the full length of the lance
Check for:
- Hairline cracks
- Splits along the seam
- Signs of pressure damage
3. Test water flow (if safe)
Run water through the lance and check for:
- Irregular spray pattern
- Visible leaks along the body

Important Maintenance Tips
- Always clear the nozzle regularly using the cleaning pin

- Store the lance securely after each use
- Flush with clean water if used with natural water sources
