  • Mode 2: Custom settings.

Test Cycle Stages (EN 12875-1 Article 8.3)

• Drain: Empty the dishwasher with a water pump.
• Pre-Wash: Fill the dishwasher with water, circulate for 5±0.5 minutes, then drain.
• Wash:
  • Fill with 6.0±0.5 L of water and 24±3 g cleaning agent per liter.
  • Heat to 60±2°C and circulate for 20±1 minutes.
  • Continue circulation for 3±1 minutes without heating.

• Rinse:

  • Add fresh water.
  • Circulate for 3±0.5 minutes.
  • Drain the system.

• Final Wash:

  • Refill with water.
  • Heat circulating water to 65±2°C.
  • Maintain 40–45°C and add 2.5–3.0 g bleach per 6.0±0.5 L of water.
  • Pump circulation continues at 65±2°C.

• Drying: Store samples inside. Keep the door closed for 3±1 minutes, then open for 30±1 minutes.

Performance Features

• Real-time water softening module controls hardness (Ca/Mg) between 0.3–0.6 mmol/L, tested per ISO 6059.
• Fixed water quantity of 6.0±0.5 L for each test. Water pressure ranges from 5 N/cm² to 100 N/cm² (pump lift 0.3–0.4 MPa).
• Accurate detergent and bleach dosing system for every cycle.
• Automatic door actuation and cycle repetition for reliability.
• Customizable programs: users can adjust heating temperature up to 80°C.
• Automatic alarms after each cycle and at the end of set test runs.
• Reports: Export raw data or reports via USB. Reports include cycle times, temperature, and water softening records.
