Your washer and dryer are designed to be simple to maintain, and there are a few things you can do that will prolong the life of the machines and reduce service calls.

• Avoid overloading the washer - an overloaded washer strains the motor and transmission, shortening their lives.
• Once a month, remove and clean intake screens where water-supply hoses enter the washing machine, and check water-supply hoses for splits, cracks, or bulges.
• Once a year, disconnect your dryer from the vent hose and wall, and thoroughly vacuum and clean the lint pipe to improve your drying efficiency and remove potentially flammable lint buildup. 
• Once a year disconnect the washer and dryer to clean underneath and check for any small leaks or hidden maintenance problems.
