Which doesn't diminish what it's purpose is and it's effectiveness.

But a new washing machine isn't the only electronics in the house.
Like Gfre says, best strategy is a whole house surge protector at
the panel or meter, with point-of-use type at eqpt that is also
connected to other lines, eg cable, phone, etc. If you're in a
situation where you can't put one on the panel, then point-of-use
at the washer can offer protection, but it's not the preferred
solution.
