Cutting the cost

Run it only when it's full, and use the eco or auto cycle, which washes longer at a lower temperature to save water and heat. Scrape the plates instead of pre-rinsing them under a hot tap. Skip the heated-dry option and crack the door open at the end to let everything air-dry. If your plan has cheaper off-peak hours, use the delay-start to land the cycle in that window.
