This was a dishwasher remove and reinstall. Went above and beyond at the reinstall. He identified a water leak, notified me, and took corrective action. Slight increase to the cost - parts and labor - but the most important aspect is the integrity of his work!

Excellent customer service, prompt in responding along with great communication. Took on a job of replacing hard wood floors after a dishwasher leak that 3 other companies were not able to do along with a handful of other various projects. Would not hesitate to hire again for future projects.

Dishwasher Installation questions, answered by experts

Maintenance includes regular filter cleaning, checking water connections, and ensuring that the unit operates at optimal efficiency without blockages.

Any drain in your house requires a water trap to prevent sewer gases from entering the home. Dishwashers don’t have an internal water trap, so they must use an external P trap. The most convenient P trap for the dishwasher is already in the plumbing under your sink.

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.

Some common signs you have a dirty dishwasher filter are:

Food sticking to your dishes even after a thorough wash cycle
Odor coming from your dishwasher
Stains left on dishes and utensils
Water pooling in your dishwasher
Food stuck to parts of the dishwasher, like the racks, walls, or sprayer arm

If your dishwasher isn’t draining, some common causes include a clogged drain filter, drain hose, or air gap. Also, if you have a garbage disposal, a clog in the disposal can back up your dishwasher since they share plumbing, as can a clog in your kitchen sink’s plumbing. A handy DIYer may be able to figure out how to unclog a dishwasher, but you may need to call in a plumber if you can’t locate and clear the clog yourself.
