How to DIY it: Take off the loose bar by removing the screws on each of the posts that mount the bar to the wall. (If one side is solidly attached, leave it alone.) With the mounting plate now exposed, try tightening the screws in it. If that doesn’t work, remove it. Chances are you’ll find two plastic anchors underneath. Poke them with a screwdriver and let them fall inside the wall. Replace with bigger, stronger metal toggle anchors (above), sold at hardware stores. Just drive them into the existing holes with a drill or a screwdriver, and then reattach everything.
How to DIY it: A simple cleaning often solves the problem. Start by pulling out the lower dish rack. Remove the spray arm and use a thin piece of wire to clean out the holes where water sprays through. Scoop or vacuum out any leftover food particles from the filter area, then remove the filter screen (above), if possible, and give it a good rinse.
If you have a small remodeling job or other work difficult to describe over the phone, you might be able to obtain fixed-price quotes without having to set up a bunch of appointments by emailing photos of the work area along with a detailed description of the work—the majority of the handyperson services we surveyed use email to correspond with clients.
