Kenmore 24" Premium Hybrid Tub Dishwasher – UltraWash, MoreSpace Adjustable Rack, High Temp & SmartWash – 12 Place Settings – 54 DBA – ENERGY STAR Certified – Fingerprint Resistant Stainless Steel

The Kenmore 24″ Premium Hybrid Tub Dishwasher is designed to handle the daily mess so you don’t have to. It combines powerful cleaning technology with a flexible interior to make the whole process simpler and more effective.
At its core is the UltraWash system. It uses two pressurized spray arms to blast away stuck-on food, aiming to eliminate the need for pre-soaking or scrubbing.
The cleaning water is continually filtered by a 3-stage UltraWash Filter that captures particles as small as a grain of fine sand, draining them away. This means dishes are washed with filtered water for a thorough clean. The filter itself is easy to remove for a quick monthly rinse, which helps maintain performance. It’s a system built for consistency.
This dishwasher also thinks for itself with SmartWash sensor technology.
It automatically detects how dirty your load is and adjusts the water temperature, pressure, and cycle time accordingly. Whether it’s a lightly soiled set of glasses or a pot with baked-on residue, it tailors the wash to get the best clean possible for that specific load. You don’t have to guess which cycle to choose.
Inside, you’ll find a spacious interior rated for up to 12 standard place settings. The key to its flexibility is the MoreSpace Adjustable Upper Rack.

With a capacity for 12 standard place settings, it’s built to manage the dishes for a mid-sized family or frequent entertainers. A standout feature is the Boost Cycle, specifically for tough messes. It tackles dried-on food without needing you to pre-rinse or scrub.

It gives you that added cleaning power right when you need it most, saving you time and effort.

This process helps prevent food from being redeposited back onto your supposedly clean dishes, so you get more consistent results.

The filter itself is easy to remove for a quick monthly cleaning, which helps maintain consistent performance. For those times when you have a smaller load, a Half Load option saves water and energy while still getting the job done.
You don’t need to figure out which cycle to choose. The SmartWash system uses sensors to detect how dirty your dishes are.
It then automatically adjusts the water temperature, pressure, and cycle length to match. This means it uses just the right amount of resources for each load, contributing to its ENERGY STAR certification. An integrated leak detection feature monitors for water where it shouldn’t be, helping to prevent potential damage before it becomes a major issue.
After washing, the SmartDry technology takes over.
GE GDT550PYRFS Top Control with Plastic Interior Dishwasher with Sanitize Cycle & Dry Boost

Its top control panel gives it a sleek, integrated look that blends seamlessly with your kitchen cabinetry, keeping the controls out of sight but within easy reach.
One of the key features here is the Steam + Sani cycle.
This option uses a steam pre-wash to help loosen tough, baked-on foods from your dishes before the main wash even begins. It then follows with a high-temperature sanitizing rinse. This cycle heats water to a temperature that’s effective at reducing a majority of common household bacteria, which is especially useful for baby bottles, pet bowls, or items that need that extra level of cleanliness.
It’s a practical function for peace of mind.
Getting dishes dry can sometimes be a challenge, but the Dry Boost function aims to improve that. By selecting this option, you add extra heat and time to the drying phase of the cycle.

Costco Dishwasher Buying Guide
Choosing teh right Costco dishwasher means balancing bulk capacity with efficient performance. You want a machine that can handle the aftermath of a big family meal or a week’s worth of dishes for two, all while keeping utility bills in check. This guide will help you focus on the key features that matter most in a warehouse club appliance.
Capacity and Rack Flexibility
Can you fit your large pasta pot on the bottom rack? Look for models with adjustable or fold-down tines, third racks for utensils, and enough interior space for oversized items. A flexible design is crucial for maximizing that famous Costco bulk.
Noise Level
If your kitchen opens to your living area, a loud dishwasher can be a real pain point. Decibel ratings are key. Models around 44 dBA are very quiet, while those above 50 dBA are more noticeable. It’s the difference between running a load during a movie or waiting until everyone’s asleep.
Cleaning and Drying Technology
Powerful spray arms and targeted zones are non-negotiable for baked-on mess. For drying, look for condensation or fan-assisted systems. Some even have a crystal dry feature that really gets plastics dry—no more towel-drying your Tupperware.
Energy and Water Efficiency
An efficient dishwasher saves you money with every cycle. Check for the ENERGY STAR label; it’s a reliable indicator of lower water and electricity use. Over a year, the savings on your bills can be significant, making a slightly higher upfront cost worth it.
Smart Features and Cycles
Do you need an app to start a wash from your phone? Smart connectivity adds convenience for some. More universally important are specialized cycles: a quick wash for lightly soiled loads, a sanitize option for baby bottles, or a heavy-duty cycle for pans. Match the cycles to your actual habits.
