Troubleshooting

Pressure washer does not start.

Check if the power cord is securely plugged in and the circuit breaker has not tripped. Ensure the water supply is turned on and connected correctly.

Low or fluctuating pressure.

Clean the integrated water filter. Check the water supply for adequate flow and pressure. Ensure no kinks or blockages are in the high-pressure hose. Verify the correct lance is attached securely.

Detergent is not being drawn.

Ensure the detergent suction hose is submerged in the detergent container and not blocked. Check that the correct setting or lance is being used for detergent application.

The high-pressure hose leaks.

Inspect the hose connections at both the machine and trigger gun for damage or improper seating. Ensure O-rings are present and intact. Replace the hose if damaged.

Unusual noise from the motor.

Ensure the unit is on a stable surface. Check water supply and filter. If the noise persists, contact customer support.

Pros and Cons

Pros

  • High pressure (180 bar) and flow rate (550 l/h) for effective cleaning of heavy dirt.
  • Versatile cleaning with two included lances (eco!Booster and Dirtblaster) for different surfaces.
  • Durable construction with a water-cooled motor and a 5-year guarantee (upon registration).
  • Convenient and user-friendly with a long, anti-twist hose and integrated accessory storage.

Cons

  • High power consumption (2.8kW) requires a robust electrical connection.
  • The unit is relatively heavy (17.3kg without accessories), potentially affecting portability for some users.
  • Not ideal for very light-duty or occasional cleaning tasks where a less powerful model would suffice.
  • Requires a water source connection, not a self-priming unit.
  • App integration requires a smartphone and internet connection for full benefit.

Setup, Compatibility & Care

Setup:

  1. Connect the PremiumFlex high-pressure hose to the Quick Connect port on the pressure washer and the trigger gun.
  2. Attach the desired lance (eco!Booster or Dirtblaster) to the trigger gun.
  3. Connect a standard garden hose (A3/4" adapter included) to a water supply and the water inlet on the machine.
  4. Ensure the integrated water filter is clean before initial use.
  5. Plug the power cable into a suitable electrical outlet (230/240V, 50Hz).
  6. Use the detergent suction hose for detergent application if needed.

Compatibility:

  • Requires a standard garden hose connection with sufficient water pressure.
  • Electrical connection requires a 230/240V, 50Hz outlet capable of handling 2.8kW.

Care:

  • Regularly clean the integrated water filter to prevent blockages and ensure optimal performance.
  • After use, flush the system with clean water, especially if detergents were used.
  • Store the unit and accessories in a dry, frost-free place.
  • Protect the pump from freezing temperatures by draining all water from the system.
  • Wipe down the exterior with a damp cloth as needed.
