Keep It Quiet
Washers and dryers transfer vibrations to floors and telegraph noise throughout the house. The solution is to set their feet on rubber anti-vibration pads (available at some home centers and online).
Keep the Dishwasher Clean
When your dishwasher no longer gets your dishes clean, a food-filled filter is most often to blame. If it's clogged, water can't make it to the spray arms to clean the dishes in the top rack. The fix takes two minutes. Simply pull out the lower rack and remove the filter cover inside the dishwasher. (Check your owner's manual if you can't spot the filter.) Then use a wet/dry vacuum to clean off the screen. While you're there, slide the nearby float switch up and down. If the cover sticks, jiggle it up and down and clean it with water.
