- Unlike other appliances, the less you use it the more likely it is to break down. Water that remains in the bottom of your dishwasher is there for a reason; it keeps seals moist, to prevent leaks and protect the motor. When not used for long periods, the water evaporates, seals dry out and leaks and motor problems become likely. To prevent this, before a dishwasher sits unused for more than two or three weeks, pour in a half cup of liquid bleach (this prevents bacterial buildup). Then add 3 tablespoons of mineral oil. These coat the surface of the water and prevent evaporation -- even over long periods of time
- First turn off the freezer dial. Then arm yourself with a turkey baster -- full of hot water. Look for the drain hole on the bottom of the freezer, way in back. It's a half-inch hole probably under water, and might be blocked with ice. Clear it, put the baster in the hole and blast away. Mold and mildew has trapped water, which then froze and clogged the drain. Pour some warm water and bleach through, too. Then remove and clean the drip pan below.
