Bertazzoni DW24S2IPB over 9 years

Is it worth replacing?
Efficient as certified dishwashers go, $45/year is a reasonable baseline if you're comparing what else is on the market.
Worth comparing a few current certified models before deciding.
If you're keeping it
The Bertazzoni DW24S2IPB already costs $45/year to run; a repair bill on top of that is the kind of expense a protection plan exists to smooth out.
