How long should dishwasher drain pumps last?

2 months ago

I had a Kenmore Elite dishwasher (rebadged Bosch) purchased about 10 years ago that needed a new drain pump a few years after purchase because it got loud.

Then around 4 or 5 years ago, I purchased a new Bosch 800 series dishwasher and now I notice a similar droning noise when water is draining.

Is it normal for dishwasher drain pumps to start droning after less than 5 years or is this a Bosch issue or is it a sign of improper installation?

I’m debating whether to pay to get the drain pump replaced and get a few more years of use out of it or upgrade to a new Bosch model with Crystal Dry or move on to Miele. I’m not sure if I want to give Bosch more business with another purchase if they have more issues than other similar dishwashers.
