Easily Troubleshoot Your Pressure Washer
This article is made with the help of ChatGPT.
Save time, reduce costs, and minimise environmental impact — all without the hassle.
Our goal is to ensure your AVA pressure washer lasts for many years. When problems arise, we want the solution to be as simple and accessible as possible. In many cases, issues can be resolved without replacing parts or sending the machine in for repair. And if a repair is needed, we’ve made it possible for you to perform it yourself — safely and affordably.
Troubleshooting should ideally be done where the machine is used — keeping in mind simple factors like fuses, power supply, and water access.
Why Troubleshooting Matters
Our experience shows that many pressure washers sent in for service are actually fully functional.
Using our troubleshooting guide has helped reduce unnecessary service cases — saving time, money, and valuable resources.
Benefits of Troubleshooting It Yourself
Time savings
Our guide helps you resolve most problems immediately — without waiting for responses, shipping, or packing. Often, checking a few key points solves the issue and gets you back to work.
Simpler handling
If a repair is required, the guide helps ensure the correct issue is identified. This avoids misunderstandings, and lets you create a return label instantly if needed. Your input helps us prepare a complete repair case and reduce delays.
Environmental benefits
Many issues can be solved on-site. For example, pulsing in standby is always caused by a leak — which is often external and easy to fix with a new O-ring.
Sending in a whole machine creates much higher emissions than posting a small spare part in an envelope.
Lower costs for you
Common user-related issues — such as poor water supply or a blown fuse — are not product faults. These may result in unnecessary shipping costs if the product is returned.
We’ll always try to support you — but frost damage, setup errors, and similar faults are not covered by warranty. They can often be ruled out with the guide.
If the issue is covered by warranty, you can order parts free of charge from our online store. If not, we still offer affordable spares and detailed guides to support self-repair.
Lower costs for AVA
Efficient troubleshooting allows us to keep offering spare parts at non-profit prices, with repair videos and guides freely available to everyone.
Pulsing in Standby? That Means a Leak. Always.
If your machine pulses or turns on and off repeatedly without pulling the trigger, this means the pump is compensating for pressure loss — caused by a leak.
Here’s how to find it:
| Possible Leak Source | How to Identify | How to Fix |
|---|---|---|
| External O-rings | Water dripping from connection points | Replace the affected O-ring |
| Spray gun leaks internally | No visible water, but pulsing still occurs | Disconnect the gun — if pulsing stops, it’s the gun |
| Leaky hose or reel | Wet areas around hose or fittings | Replace hose or check reel connections |
| Lance/gun not fully sealed | Slight trickle from nozzle or gun front | Clean/replace internal valve or seal kit |
Tip: Always start by removing accessories one at a time. Run the machine without the spray gun or hose to help isolate the leak.
Other common issues and quick fixes
| Problem | Quick Fix |
|---|---|
| No pressure | Attach correct nozzle — it’s what creates pressure |
| Wrong nozzle used | Use a compatible AVA nozzle (colour-coded) |
| Blown fuse | Replace fuse in plug or fuse box |
| Water not turned on | Open tap fully, remove Aquastop fittings |
| Trigger not pressed | Pull the trigger — machine won’t run when already pressurised |
| Clogged water filter | Remove, rinse under tap, reinstall |
| Using extension cord | Must be 2.5 mm². Try plugging directly into the wall |
| Low voltage | Check that mains voltage matches unit rating |
| Air trapped in system | Run machine without accessories to purge air |
| Frost damage | Look for cracks in pump or parts. Not covered by warranty. |
