Why does a dishwasher have to drain through the sink plumbing?

Larry arrived the same day that I called to figure out what was wrong with my very old dishwasher. That kind of service is unheard of in this day and age. Pleasant and very knowledgeable. Greatly appreciated his patience. Will call again in the future.

Dishwasher Installation questions, answered by experts

Installing a dishwasher should take one to four hours, depending on the complexity of the installation and whether you DIY or hire a pro. Even if you're particularly handy, installing a dishwasher on your own will likely take longer — at least two hours. On the other hand, a professional can likely install a dishwasher in about an hour. Installation time will take longer if you have to remove an existing dishwasher, reroute plumbing, or repair damaged flooring underneath the appliance.

A dishwasher can help save you significant time when it comes to getting your dishes clean. It can also get your dishes more hygienically clean than washing by hand due to higher water temperatures and specialized detergents, effectively sanitizing them and reducing the risk of foodborne illnesses. Compared to hand-washing, a dishwasher typically uses less water and energy to clean the same amount of dishes, making it a more resource-efficient option.

Only if the dishwasher isn’t made of stainless steel. The corrosive chemicals in bleach will stain stainless steel and can also cause further damage. To stay on the safe side, stick with an extra cycle of vinegar to banish any lingering odors.

Yes, if your filter is damaged or simply too debris-filled to be of use, replace it with a new component. Check the instruction manual that accompanied the dishwasher for information as to the specific part. There are many online marketplaces that sell these parts, but perform due diligence to ensure you buy the right one.

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.
