On the episode where Alice sprains her ankle, Jan enters Alice's bedroom to check on her. She tells her about the little accident where the washer is overflowing and that suds are all over and need to be cleaned up, as well as the clothes that were in the wash that have floated all over the house in the water flow. Later, when Mr. Brady comes into Alice's bedroom, the door is open behind him which is clearly the laundry room with ironing board and utility sink and laundry soap. If the washer had overflowed, where Peter had to clean up the water in the dining room, there is no doubt it would have been realized in Alice's bedroom.
