Do they make a 22 inch wide dishwasher?
Yes. Dishwashers are commonly sold in multiple widths, and 22-inch-wide models do exist, although they are less common than standard 24-inch units. For a KitchenAid dishwasher like model KUDS22ST0, always measure your cabinet opening before shopping so the new unit fits.
Common dishwasher widths (what you will see most often)
- 24 inches: standard built-in dishwasher size for most kitchens
- 18 inches: compact built-in size for tight spaces
- 22 inches: less common; used when a 24-inch unit will not fit but 18 inches is too small
| Nominal width | Typical use case | Availability |
|---|---|---|
| 18 in. | Small kitchens, apartments | Common |
| 22 in. | Odd-size openings, older cabinetry | Limited |
| 24 in. | Most built-in installs | Most common |
How to confirm what size you need
Measure the cabinet opening, not the old dishwasher door.
- Measure width at the front and back of the opening (cabinets can be out of square)
- Measure height from floor to underside of countertop
- Measure depth to confirm the door will clear adjacent cabinets and handles
- Check for clearance around water line, drain hose, and power connection
Why it matters
A dishwasher that is even slightly too wide will not slide into the opening, and forcing it can damage cabinets, the tub, or the water inlet and drain connections. Getting the width right first saves time and prevents installation headaches.

How old is my KitchenAid KUDS22ST0?
Your KitchenAid dishwasher model KUDS22ST0 does not have a single “age by model number” date. To tell how old it is, we use the serial number (date code) from the rating label, then decode the manufacturing week and year.
Where to find the serial number on KUDS22ST0
On most KitchenAid dishwashers like KUDS22ST0, the rating label is typically:
- On the tub frame along the door opening (left or right side)
- Along the top edge of the door or inner door panel
- Occasionally on the side of the tub behind the door seal area
Write down the full serial number exactly as shown (letters and numbers).
How to decode the age (what the serial number tells you)
KitchenAid serial numbers commonly include a date code that identifies when the dishwasher was built. The exact format varies by production era, but the goal is always the same: identify the manufacturing year and often the week.
Use this quick checklist while decoding:
- Look for a week number (01 to 52) or a letter that represents a month/week
- Look for a year indicator (often a digit or letter tied to a year)
- Confirm the format by matching the serial pattern to KitchenAid/Whirlpool-style coding
What you can determine from the serial number
| What you want to know | What to look for | What you get |
|---|---|---|
| Approximate age | Year code in serial | Build year (sometimes exact) |
| More precise age | Week plus year code | Build week and year |
| “How old today?” | Build date + today’s date | Age in years/months |
Why it matters
Knowing the manufacturing date helps us choose the right dishwasher parts and avoid mismatches, especially for items that changed mid-production (like a water inlet valve, float switch, or dishrack hardware).

Is KitchenAid stainless steel coated?
Yes. Many KitchenAid stainless steel finishes use a clear, protective top coating designed to reduce fingerprints and make routine cleaning easier; the exact finish depends on the specific product line, not the KUDS22ST0 dishwasher model itself.
What “coated” usually means on KitchenAid stainless
KitchenAid commonly uses a fingerprint-resistant clear coat on certain stainless and black stainless finishes (often marketed as PrintShield on newer products). That coating is not a separate film you peel off; it is part of the exterior finish.
- Helps resist smudges and fingerprints
- Makes cleaning easier with mild methods
- Can be damaged by abrasives or harsh chemicals
- May look slightly different than uncoated stainless under bright light
How to clean coated stainless without damaging it
Use gentle cleaning methods first; this protects the coating and prevents dull spots.
- Wipe with warm water and a soft microfiber cloth
- Dry immediately to prevent water spotting
- For greasy marks, use a small amount of mild dish soap, then rinse-wipe and dry
- Wipe in the direction of the grain (if visible)
- Avoid steel wool, scouring pads, and powdered cleaners
Cleaner do’s and don’ts (quick guide)
| Cleaner type | Recommended? | Why |
|---|---|---|
| Water + microfiber cloth | Yes | Safest for coated finishes |
| Mild dish soap (diluted) | Yes | Lifts oils without abrasion |
| Glass cleaner with ammonia | No | Can haze or streak some coatings |
| Abrasive pads/powders | No | Can scratch or wear the coating |
Why it matters
A coated stainless finish can look great for years, but the coating is easiest to keep looking uniform when you avoid abrasives and harsh solvents. If you see dull patches, they are often from cleaner damage rather than normal wear.
If you are touching up chips or scratches on non-stainless areas (such as the frame or panel edges), use an appliance touch-up product intended for that surface, such as touch-up paint WP72107.
