连词我觉得没什么,不必非得刻板地改成first second third.
那个push down改成press的确会比较好.还有,finally那一句最好说明是在什么时候,也就是“After the machine stops,take out the clothes”或者“After xx minutes,take out the clothes”.
没有必要加That's all.这种说明性质的文字,越简练越好.

First, put the laundries into the machine.
Second,add some soap powder.
Third,turn on the machine.
Finally,take out the clothes from the machine.
That's all.
