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

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.

Most repairs take 1-3 hours, but complex issues requiring part replacements may take longer if parts need to be ordered.

Some signs that your dishwasher is going out include:

The door no longer latches
Dishes are still dirty after a cycle
Dishes are cold after a cycle
Rust inside or outside the unit
Cracks inside the dishwasher tub
Water collecting at the bottom or outside the unit

If your dishwasher is not energy-efficient or is older than 10 years, you should also consider replacing it. Repairing an older model may be more expensive than replacing it with something newer and more energy- or water-efficient.

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.

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