The dishwasher is one of the most important appliances in your home—it is convenient, efficient, and fast. But like any machine, if it is not well-maintained, it will eventually create expensive problems. To help you tackle any dishwasher difficulties before they become worse, the pros at Sal Manzo Plumbing, Heating & Cooling Inc. have created a handy guide to solving common dishwasher problems.

Dishes Coming Out Dirty

If your dishes are still covered in grease or food scraps after a full cycle, the problem usually lies in the sprayer arms. These arms rotate and spray high-pressure hot water to clean your dishes. Check to ensure no tall utensils are blocking the arms from spinning. If the arms are clear, use a toothbrush to clean the small holes in the sprayer arms to remove any mineral or food buildup that might be affecting water pressure.

Pro Tip: Always ensure you are loading the dishwasher properly to allow for maximum water circulation, and use a high-quality detergent suited for your local water hardness.

Eliminating Bad Odors

Particularly bad odors are almost always caused by food buildup in the filter. To prevent smells, you should clean your dishwasher filter about once a month. Most filters are located underneath the lower sprayer arm. Depending on your model, you may have a flat filter and a cylindrical one; remove both and rinse them thoroughly with warm, soapy water.

Deep Cleaning with Vinegar

To remove gunk buildup and disinfect the interior gaskets, use a vinegar rinse. Place a dishwasher-safe bowl containing one cup of white vinegar on the top rack of an otherwise empty dishwasher. Run a standard hot water cycle; the vinegar will break down grease and lime scale while refreshing the interior of the machine.

Handling Dishwasher Leaks

Leaks are typically caused by a damaged door gasket (the rubber seal around the opening) or cracked supply lines. Inspect the gasket for cracks or brittle spots; if it’s damaged, it should be replaced immediately to prevent floor damage. If the seal looks good but you still see water, the issue may be a loose fitting or a cracked pipe underneath the unit.

Conclusion

A little bit of regular maintenance can extend the life of your dishwasher and keep your kitchen running efficiently. By cleaning the filter and checking the sprayer arms, you can avoid most common performance issues. However, if your dishwasher continues to leak or fail to drain, it’s best to call in a professional to check the plumbing connections.
