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

• <div><p>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.</p></div>

Do dishwashers need routine maintenance?

• <div><p>Dishwashers should be cleaned a minimum of once every 3 months, but really it should be done monthly. This is to prevent germ buildup and will help keep your machine running smoothly. Dishwasher maintenance isn’t too difficult, you’ll simply clean the filter, wipe down the spray arms with vinegar or rubbing alcohol, and run the cycle on empty. If there is any debris, you can remove it with a small metal pick. Do not use wood as the tip can break off inside the machine. </p></div>

Dishwasher Installation questions, answered by experts

Basic maintenance, such as cleaning filters, is DIY-friendly, but repairs involving electrical components, pumps, or valves should be handled by a professional.

A clogged air gap can cause a dishwasher not to drain. There are, however, other potential issues that can lead to improper drainage. For example, if you have attached the air gap to a garbage disposal and forgotten to remove the knockout plug, wastewater may backflow into the dishwasher. Check that the air gap is installed properly, and then look for clogs in the air gap and dishwasher filters.

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.

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.

Dishwashers should be cleaned a minimum of once every 3 months, but really it should be done monthly. This is to prevent germ buildup and will help keep your machine running smoothly.
