Fill what you know. If a value is unknown, keep the practical default and verify the nameplate later.

Dishwasher Wattage (W)

Hours Per Cycle

Cycles Per Month

Electricity Rate (â‚¹/kWh)

Use this page to estimate dishwasher energy from cycle time and number of monthly cycles. Eco mode and full loads can reduce waste.

This is a preliminary planning estimate. For certified audits, use site measurement and nameplate readings.

Is this result exact?

It is an engineering estimate using user inputs. Exact result needs actual meter/nameplate data.

Can I use it for audit report?

Yes, as a preliminary calculation and supporting estimate.

Run full loads and use eco mode when possible. Daily partial loads can increase both water and energy cost.

The result is a planning estimate. Use nameplate wattage, measured runtime and current tariff for professional-level accuracy.
