Whirlpool washing machines and dryers have an expected lifespan of 10 years so you should get at least 10 years of use out of the Whirlpool washing machine without needing to replace it or repair it during that time.
I have a Whirlpool washing machine and dryer set that is 12 years old now so you can get a little longer than 10 years out of the washing machine and dryer but I'm gonna be replacing the washing machine and dryer set soon just because of their age.
