I hired this pro because he was honest about how difficult it is to deal with cutting tile around faucets in these old houses. He recommended cutting a big portion so the tile could be repaired if it broke but I would need a tile person to come in and fill in the tile. When he heard it was my...

Dishwasher Installation FAQs, answered by experts

Limescale can build up outside your dishwasher if you live in a home with hard tap water. Any household surface exposed to water and heat may have unsightly limescale deposits, including kettles for boiling water, sinks, countertops, toilets, taps, tubs, shower doors, glassware, and aquariums. Glass, laminate, porcelain, granite, and other similar surfaces can all have limescale.

It’s not worth fixing a 20-year-old dishwasher or any 20-year-old appliance. Twenty years is beyond the useful life span of nearly every major household appliance. Once the appliance nears the end of its useful life span, repairs will become more frequent. A replacement often becomes more cost-effective at that point.

Regular use helps keep interior dishwasher parts functioning properly and the interior clean. Try to run your machine at least once every two weeks as part of your dishwasher cleaning schedule.

Every six months, running two cups of white vinegar through your dishwasher (place the vinegar where you put detergent) will help deep clean the unit to boost performance.

A standard dishwasher size is 24-by-24-by-35-inch for a built-in unit. The depth and height line up perfectly with most kitchen countertops and cabinet sizes.

No, you do not need a garbage disposal to have a dishwasher. A dishwasher will work without one, and while it's rare to see a home with a dishwasher that doesn't have a disposal, it is possible. The two appliances pair well and are often installed together because a disposal simplifies meal cleanup.

However, your dishwasher should not be used as a replacement for a garbage disposal. Subjecting it to continuous food leftovers can lead to major clogs. If you choose not to install a garbage disposal, you should thoroughly rinse your plates or scrape excess food into the trash or a compost pile before loading them into the dishwasher to prevent plumbing issues.
