Question

machines have to be maintained

Answer 1

Replace the water hoses. Check hoses regularly for bulging, cracking, fraying, and leaks around the ends. Replace the hose if a problem is found or every three to five years as part of a proactive maintenance program. 
Move the machine. Check that there are at least four inches between your washing machine and the wall. This prevents hoses from kinking. 
Keep the machine level. A washing machine that's off kilter can vibrate, rock, or "walk" across the floor during the spin cycle, which can damage the floor or the machine. Balance the washer by turning the legs clockwise to lower it, and counterclockwise to raise it. 
Clean the lint filter. Depending on your machine, the lint collector may be located in the agitator tube, which is the center column of most machines, or near the top of the washtub. Keep it clean to help your washer run efficiently. 
Wash the washing machine. Rinse away soap residue and buildup by running store-bought washing machine cleaner, or a solution of hot water, vinegar, and baking soda through an empty load.
