Protect your investment
Here are some hints to help keep your appliances longer:
Clothes dryer - Clean lint filter after every drying cycle and keep vent hose clear. Clogging could burn up the motor. I had the unfortunate experience of learning this the hard way! 10-13 years life expectancy.
Dishwasher - Keep drains clear of debris by pre-rinsing dishes. If you normally hand wash your dishes, use your dishwasher at least a few times a month. Otherwise the rubber hoses will harden and be brittle, resulting in leaks. 10-12 years life expectancy.
Garbage disposal - Have cold water running the entire time the disposal is in use. Using cold water allows fats to coagulate and drain out while hot water melts the fats when the water is hot, but will coagulate against the cold pipes further down. Also pour ice cubes into the drain while the disposal is running to clean the blades. It makes a lot of noise, but it will not hurt the disposal. 6-12 years life expectancy.
