based upon my current experience, get the extended warranty when buying a dehumidifier!
I have two, the 70ppd $$ Kenmore ran 3y, base charge is 30% of cost! The 50ppd ran 2, it was still in warranty & I bought more warranty 2 times now.
The 1986 Whirlpool ran 10y, or more! [ I used to help repair that production line = one first task in 1984, was for the double sheet protector = detecting that 2 blanks did not try to feed into the chassis bender.]
