This step-by-step guide shows you how to replace the pump and motor on your AVA Easy P30-P60.
Regular maintenance improves long-term performance and can help resolve frost damage. Although the product warranty is limited to a maximum of 10 years, there is no reason your machine shouldn't last even longer with proper care. If your machine is not yet 10 years old and you’ve followed the service schedule, remember to register your 5-year service or pump/motor replacement here.*
The service itself doesn’t involve many steps, but each one is described in detail to make the process as easy as possible for you – and to ensure the best possible result. We recommend reading through all the steps before you begin, so you understand the procedure and have the necessary tools to complete the task.
Always unplug the pressure washer from both the mains power and the water outlet before starting the service.

Even though power and water is disconnected there may be pressurized water in the hose. Discharge this pressure by pulling the trigger on the gun.
Make sure your work area is clean and appropriate for the work you are about to do. There will usually be a small amount of water inside the pump and hose.
When you are doing a change of motor/pump, be prepared to collect the used oil from the oil chamber. Please dispose of the oil in accordance with local law and regulations.
ISO 46 hydraulic oil can be substituted with similar non detergent oil of the same viscosity.

Troubleshooting
Water is leaking from the inside
- Disconnect the power and open the pressure washer to locate the leak. Take necessary action to remedy any leaks.
Motor runs and won't stop when you release the trigger
- This is most likely due to an improper seating of the switch box on the start/stop valve.
- Open the machine and check that the switch box is correctly seated.
The pressure washer won't turn on
- Check that the power cable is connected.
- Check that the circuit breaker has not been tripped.
- Check that the fuse in the power plug is intact (UK models only).
- Open the machine and check that all the internal cabling is connected.
Poor performance/pressure
- Improper assembly or dirt/debris in the pump.
- Check that the pump and especially the main valve for foreign objects/debris.
- Make sure that the spring in the main valve is correctly seated and working as intended.
- Remove and clean waterfilter.
- Try with other nozzles. If that helps, clean the nozzle. If cleaning makes no different, a new nozzle must be purchased.
- Check for leakages
- Check that water pressure/amount is suffient.
