Test Cycle Stages (EN12875-1, BS 5416 Article 8.3)

1. Drain: Empty dishwasher with water pump.
2. Pre-Wash:
   • Fill dishwasher with water.
   • Circulate for 5 ± 0.5 min.
   • Drain again.
3. Main Wash:
   • Add 6.0 ± 0.5 L of water and 24 ± 3 g detergent per liter.
   • Heat to 60 ± 2°C while circulating for 20 ± 1 min.
   • Continue circulation for 3 ± 1 min without heating.
4. Rinse:
   • Add water.
   • Circulate for 3 ± 0.5 min.
   • Drain system.
5. Final Wash:
   • Refill with water.
   • Heat to 65 ± 2°C.
   • Add 2.5–3.0 g bleach per 6.0 ± 0.5 L of water (at 40–45°C).
   • Pump circulation continues until water reaches 65 ± 2°C.
6. Drying:
   • Keep door closed for 3 ± 1 min.
   • Open door for 30 ± 1 min.

Performance Features

• Water softener (cation exchanger) controls hardness at 0.3–0.6 mmol/L (ISO 6059 method).
• Fixed water volume: 6.0 ± 0.5 L per test cycle.
• Water pressure: 5–100 N/cm² (pump lift 0.3–0.4 MPa).
• Thermostat accuracy: ±2°C.
• Automatic detergent/bleach dosing for each cycle.
• Door actuation ensures automatic repetition of test cycles.
• Cycle counter records both single and cumulative runs.
• Programmable temperature up to 70°C (custom mode).
• Automatic alarms after cycle completion.
• Data export via USB (raw data and formatted reports).

Construction and Safety

• Stainless steel main frame for durability.
