85% Water ReductionMassive Water Savings vs Traditional Hand Washing
Manual hand washing of 13 place settings uses ~60 Liters of running tap water. Modern dishwashers use only 9.5 Liters per load—saving over 1,500 Liters of fresh water every month!

Standardized Energy & Water Methodology Disclosure:
- Dishwasher power consumption is measured per wash cycle (kWh/cycle) under IEC 60436 standard testing conditions.
- Modern dishwashers use ~9.5 Liters of water per Eco cycle versus ~60 Liters for traditional manual hand washing of 12-14 place settings.
- Calculated electricity and water costs preserve double precision internally while rounding presentation values.
How Dishwasher Electricity & Water Consumption is Calculated
Dishwashers draw power primarily during water heating phase (1,800W–2,400W heater) and drying. Standardized IEC 60436 testing measures energy per cycle (kWh/cycle) and water per cycle (Liters/cycle).
Monthly Energy (kWh) = kWh per Wash Cycle × Monthly Wash Load Cycles
Monthly Water (Liters) = Liters per Wash Cycle × Monthly Wash Load Cycles
Worked Example (Bosch 13 Place Setting): 0.92 kWh/cycle × 30 cycles = 27.60 Units/month (₹207.00/month @ ₹7.50/unit) & 285 Liters water/month
