The graph above shows the way a normal dishwasher uses electricity. The dishwasher was set to position 3 on the dial (which according to the front panel is “Normal Wash 60 C”) and run through a normal cycle. You can see a number of key characteristics:
-
The dishwasher is almost entirely a resistive load. The kW and KVA readings coincide almost completely.
-
Dishwashers are clearly quite power hungry.
The summary figures for the test are:
Max. Power drawn | 2026W |
Average Power drawn | 1070W |
Max. Volt-Amps drawn | 2026VA |
Average Power Factor | 88.9% |
Total energy consumed | 1.07kWh |
