Your Costco Dishwasher Buying Guide: Clean Dishes Made Easy
Buying a new dishwasher is a big decision for any home. Costco offers a great selection of dishwashers. These appliances can save you time and effort. This guide helps you choose the best one for your family’s needs.
Key Features to Look For
When you shop at Costco for a dishwasher, several features really matter. Think about what you wash most often.
Capacity and Racks
- Tub Size: Most dishwashers fit standard spaces. Look at the interior space. Can it hold big pots and tall glasses?
- Adjustable Racks: Good dishwashers let you move racks around. This flexibility helps you fit oddly shaped items.
- Third Rack: Some models have a shallow third rack at the very top. This is perfect for silverware and small utensils. It frees up space below.
Cleaning Power and Cycles
- Soil Sensors: Smart sensors check how dirty your dishes are. They adjust water and time automatically. This saves energy and water.
- Cycle Options: Look for cycles like ‘Heavy Wash’ for tough baked-on food and ‘Quick Wash’ for lightly soiled items.
- Drying System: Heated dry systems work fast. Condensation drying uses less energy but might leave some moisture.
Noise Level
Dishwashers run often. You do not want a loud machine. Noise level is measured in decibels (dBA). Lower numbers mean quieter operation. Look for models under 45 dBA for very quiet running.
Important Materials Matter
The materials inside the dishwasher affect how long it lasts and how well it cleans.
Tub Material
- Stainless Steel Tub: These tubs resist stains and odors better than plastic. They also handle high heat well, which improves drying performance. Most high-quality dishwashers use stainless steel.
Racks and Spray Arms
- Durable Racks: Racks should have a strong nylon coating. This protects your dishes from scratches.
- Spray Arms: More spray arms mean better water coverage. Look for stainless steel spray arms for durability.
Factors That Improve or Reduce Quality
Quality isn’t just about the brand name. Design choices make a big difference.
Quality Boosters
- Hard Food Disposer: Some models grind up large food particles. This stops the drain from clogging.
- Reliable Motor: A strong, efficient motor cleans thoroughly without breaking down quickly.
- Good Warranty: A longer warranty shows the manufacturer trusts their product. Costco often provides good return policies too.
Quality Reducers
- Plastic Bottoms: If the base of the tub is plastic, it might wear out faster than stainless steel.
- Few Spray Jets: A dishwasher with only one or two spray arms might miss spots on your plates.
User Experience and Use Cases
Think about how your family uses dishes every day.
For Busy Families
If you have large families, prioritize capacity and tough cleaning cycles. A quick wash option is essential for daily use. Loading flexibility with adjustable racks saves time when you are rushing.
For Small Spaces or Open Layouts
If your kitchen connects to your living room, choose a very quiet model (under 45 dBA). You won’t hear it running during movie night. Easy-to-use controls also make the experience smoother.
Costco often bundles installation options or extended warranties. Always check these extras when making your final decision.
10 FAQs About Costco Dishwashers
Q: Does Costco install the dishwasher I buy?
A: Sometimes, Costco offers installation services through third-party partners. You must check the specific product page or ask a sales associate during purchase. Installation is often an extra fee.
Q: Are the dishwashers sold at Costco the same as in other stores?
A: Often, the models are similar, but sometimes Costco gets exclusive packages. These packages might include unique features or different color options compared to other retailers.
Q: What is a good noise level rating (dBA) for a quiet dishwasher?
A: A rating below 45 dBA means the dishwasher is very quiet. Anything under 50 dBA is generally considered quiet for a standard home kitchen.
Q: Do these dishwashers use a lot of water?
A: Modern dishwashers are very water-efficient. Most high-efficiency models use between 3 to 5 gallons of water per load. Soil sensors help reduce water use when dishes are lightly soiled.
Q: What happens if my new dishwasher breaks down?
A: First, check the manufacturer’s warranty. Second, check Costco’s return policy. Costco generally has a generous return window, but after that, you deal with the brand for service.
Q: Should I choose stainless steel or plastic tubs?
A: Stainless steel tubs are superior. They dry dishes better because they retain heat. They also resist staining and odors over many years of use.
Q: What is the benefit of a third rack?
A: The third rack sits at the very top of the dishwasher. It holds flat items like silverware, spatulas, and small bowls. This frees up valuable space in the lower racks for pots and plates.
Q: How long does a typical dishwasher last?
A: With good care, a quality dishwasher should last between 10 to 15 years. Regular cleaning of the filter helps extend its life.
Q: Do I need to pre-rinse my dishes before loading them?
A: No, modern dishwashers and detergents are designed to handle food residue. Just scrape off large chunks of food. The soil sensors need some dirt to work correctly.
Q: What size dishwasher should I buy?
A: Most standard dishwashers are 24 inches wide. Measure the opening in your cabinetry before buying. If space is tight, look for smaller 18-inch models.
