Several signs can tip you off to a clogged dishwasher drain. At first, you may notice that it’s taking longer than usual for the dishwasher to drain, or you may hear gurgling sounds during the draining part of the cycle. You might also notice water backing up into your sink or excess food at the bottom of the dishwasher after a load. The most obvious sign, though, is seeing standing water at the bottom of your dishwasher after the cycle has finished.

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.

When deciding whether to repair or replace your dishwasher, consider its age, the repair cost, and its warranty status. It is often worth repairing a dishwasher if it is only a few years old, the problem is minor, or the appliance is still under warranty. A common guideline is the 50% rule: if the repair cost is less than 50% of the price of a new unit, a repair is generally recommended. However, if the dishwasher is more than 10 years old or requires frequent repairs, replacement is likely the more cost-effective choice to avoid future issues. For context, a new dishwasher costs between $1,000 and $1,500 on average, while typical repairs cost several hundred dollars. Simple fixes like a damaged gasket or clogged filter can be inexpensive, but major repairs like a new pump or motor can be costly.

There are some dishwasher care tips to extend its longevity and keep your dishes sparkling. Not overloading your dishwasher is key to letting water and soap move freely through the unit. Too much soap can stress your dishwasher unnecessarily, causing it to break down sooner. 

Cleaning your dishwasher is essential for its performance, so every three to six months, put two cups of white vinegar in a dishwasher-safe cup on the top rack and run a complete cycle. When done, place ¼ cup of baking soda inside and run a short cycle to eliminate any lingering odors.
