A reliable dishwasher can make your life easier, but only if it’s running at peak performance. Just like any other hardworking appliance, dishwashers need routine maintenance to stay clean, efficient, and long-lasting. At Garner Appliance & Mattress, we often hear from customers who are surprised by how much a little care can extend the life of their appliances and improve performance. Whether your dishwasher is brand new or a few years old, this comprehensive guide will walk you through everything you need to know to keep it in great shape.
1. Clean the Filter Regularly
Your dishwasher filter traps food particles and debris to prevent clogging. Over time, buildup can reduce efficiency and lead to unpleasant odors. Most modern dishwashers have an easily removable filter located at the bottom of the tub.
- Remove and rinse the filter under warm water every 2–4 weeks.
- Use a soft brush or sponge to gently scrub away any residue.
- Be sure to reinstall it securely to avoid poor drainage.
At Garner Appliance & Mattress, our team can help you identify your model’s filter style and show you how to remove and clean it properly.
2. Wipe Down Spray Arms and Seals
The spray arms in your dishwasher circulate water for a thorough clean. If the nozzles become clogged, your dishes may come out less than sparkling.
- Inspect the holes in the spray arms for mineral buildup or debris.
- Use a toothpick or small brush to gently clean them out.
- Wipe down the rubber door seals and around the door frame to remove any grime or mold buildup.
Keeping these parts clean ensures proper water flow and prevents the formation of odor-causing bacteria.
3. Run a Cleaning Cycle
Even though your dishwasher cleans dishes, it needs a deep clean from time to time.
- Run an empty dishwasher with a cleaning tablet or a cup of white vinegar placed in a dishwasher-safe bowl on the top rack.
- Choose the hottest wash cycle to break down grease and limescale.
- For extra deodorizing, sprinkle baking soda across the bottom and run a short cycle.
We recommend doing this about once a month to keep things fresh and running smoothly.
4. Watch for Warning Signs
Minor issues can become costly problems if left unaddressed. Keep an eye out for:
- Standing water in the bottom of the tub
- Dishes not getting clean after a full cycle
- Unusual noises or vibrations
- Foul smells despite cleaning
These could be signs of clogs, motor strain, or drainage issues. If something doesn’t seem right, consult your dishwasher’s manual, or stop by Garner Appliance & Mattress, and we’ll help troubleshoot the issue or connect you with service support.
5. Use It Right
Daily habits can affect your dishwasher’s performance over time.
- Scrape food from dishes, but avoid pre-rinsing with soap, as it can interfere with detergent effectiveness.
- Don’t overload racks; water needs to circulate freely.
- Use the right detergent for your water type (hard vs. soft).
- Make sure nothing is blocking the detergent door or spray arms.
Following the manufacturer’s instructions ensures you get the most out of every cycle.
