We have three sinking our house and a dishwasher.

• if your dirty dish needs to be hand-washed, put it in the pantry sink.
• if your dirty dish is dishwasher safe, put it in the dishwasher
• if the dishwasher is full, turn it on and put your dish in the sink next to the dishwasher.
• if the dishwasher is clean, empty it, then refill it from the sink next to the dishwasher.
