Servicing your dishwasher regularly—ideally cleaning the filter weekly and running a deep-cleaning cycle monthly—extends its lifespan and prevents foul odors and poor cleaning performance.
Keep your dishwasher running efficiently and smelling fresh with a simple maintenance routine. Clean the filter every 1–2 weeks, wipe down the door gaskets, and run a monthly cleaning cycle with a dedicated dishwasher cleaner or white vinegar. Scrape—don’t pre-rinse—dishes, and check spray arms for clogs.
Regular maintenance can help extend the life of your dishwasher and prevent costly repairs. Here are some tips to keep your appliance in top shape: Clean the Filter: Remove and clean the filter regularly to prevent clogs and improve cleaning efficiency.
A good rule of thumb is to not spend more than half the cost of a new appliance on repairs. Generally, if your dishwasher is under 5 years old or a high-end model, a repair is highly worth it. If your unit is over 8–10 years old and the repair costs exceed $200–$300, replacing it is usually the smarter move.
9 Dishwasher Maintenance and Cleaning Tips
The most common dishwasher fault is clogged or poor drainage. This occurs when food debris, grease, or foreign objects (like broken glass or food particles) block the primary drain filter, the drain hose, or the garbage disposal connection, leaving dirty, standing water at the bottom of the unit.
Average Cost of Dishwasher Repair
For a technician to just take a look at the dishwasher to see what's wrong with it, you can expect to spend anywhere from $50 to $100, plus the cost of any repairs that are needed. The highest price you will likely see for a dishwasher repair is around $350.
The average lifespan of a dishwasher is 10 to 12 years. With proper maintenance and light use, some machines can last 15 years or more, while heavy use or high heat cycles may reduce this lifespan.
The control board or electronic control unit is typically the most expensive part in a dishwasher. It manages all the dishwasher's functions, such as the wash cycles, water temperature, and the timing of the washing and drying processes.
People put crumpled aluminum foil in the dishwasher primarily as a hack to make silver or stainless steel utensils and cutlery look shinier.
> Federal efficiency standards transformed dishwashers into marathon cleaners. Modern machines take 2.5 to 4 hours per cycle—a far cry from the quick turnarounds families actually need.
Using dish soap in a dishwasher creates a thick, sudsy foam in the appliance that can overflow through the dishwasher door. This is due to the formula of dish soap that relies on suds and bubbles to clean dishes. On the other hand, dishwasher detergent relies mostly on enzymes to get your dishes clean.
Dishwasher cleaning instructions. Begin your clean by removing any food residue from the dishwasher interior. Then, wipe away grime from the inside of the door, its edges and the control panel before removing and cleaning your dishwasher filter. Finish off by wiping down the exterior door panel, sides and handle.
Using a dishwasher is significantly cheaper and more efficient than washing dishes by hand, provided you run a full load. While hand washing costs more in hot water and energy, a dishwasher's real long-term savings come from preventing the massive waste of water and saving hundreds of hours of your time.
Cleaning your dishwasher with vinegar and baking soda is an easy way to help eliminate odors, grime and buildup without heavy scrubbing. Start with an empty dishwasher, then clean out the filter and run separate cycles with vinegar, followed by baking soda (never both at the same time), to help freshen the interior.
Issues like leaks, poor drainage, unclean dishes, foul odors and overall appliance operation, though infrequent, can be the most common problems with a dishwasher that isn't operating properly. In some cases, you can resolve these issues with a little elbow grease and the help of your product manual.

Note: For fire safety reasons, only run appliances like dishwashers while you're home, and try to avoid running them when you're sleeping. If you're not a night owl, consider running the machine early in the morning before you go to work to still snag the cost savings.
Your dishwasher is likely failing if you notice pooled water at the end of a cycle, persistent burning smells, or dishes consistently coming out dirty or cold. These issues often point to failing motors, faulty heating elements, or blocked pumps.
Yes, a 5-year-old dishwasher is usually worth repairing. The average lifespan of a dishwasher is 8 to 12 years, and a 5-year-old unit is generally past its initial manufacturer warranty but still has plenty of life left to justify the cost of minor fixes.
Drainage Problems: If the dishwasher isn't draining properly or if water is backing up into the sink, that's a plumbing issue. A plumber can diagnose and fix problems with the drain lines, or unclog any blockages that may be preventing proper drainage.
1) Start with the age of your dishwasher
Under 5 years old: Repair is usually the first option, especially for common failures. 5–8 years old: It depends on the problem, repair cost, and overall condition. 8–12+ years old: Replacement often makes more sense for expensive repairs or repeat issues.
Hiring a professional to unclog a dishwasher costs between $75 and $200, with most homeowners paying around $150. This price typically covers a standard diagnostic fee ($50–$100) and about an hour of labor. Severe clogs requiring a plumber to snake the pipe can cost up to $450.
