The short answer for 11- and 12-inch plates
Do not assume they fit. HAVA’s product pages list up to 10.6 inches angled, but its general US FAQ also mentions 11 inches. That conflict needs exact-model confirmation. BLACK+DECKER specifies up to 10 inches. We have not verified an 11- or 12-inch fit for the other three models in our shortlist. That is an evidence gap, not proof that every countertop dishwasher rejects large plates.
If washing your large dinner plates is the main reason to buy, get an exact-model answer before ordering. If mugs, bowls and smaller plates fill most of your sink, a compact machine may still remove a worthwhile daily chore.
Look up the evidence for your plate size
Enter a round plate’s outside diameter or a square plate’s side length. This summarizes the documented limits below; it cannot approve a loading arrangement.
Measure the outside rim, not the flat eating surface. Changing units converts your entry. Press Enter or choose Show plate evidence to see the result.
Choose your measurements to see the relevant evidence. The full six-model table remains available below.

Measure the dishes you actually use
Take your usual dinner plate, deepest bowl and tallest glass out of the cupboard. Record their dimensions before comparing appliances. A capacity label cannot tell you whether your favorite dishes will take the place of the manufacturer’s example load.
Original measuring illustrations; not rack diagrams or scale drawings.
If your round plates are 10 inches
You have documented candidates: HAVA R01 and R09 list an upright limit of 10.2 inches; BLACK+DECKER BCD6W lists plates up to 10 inches. The COMFEE CDC17P2AWW manual also illustrates a load containing two 10-inch dinner plates. Treat these as a starting shortlist: rim depth, rack position and the rest of your load still matter.
Need manual tank filling? Compare HAVA R01 with R09 or read the COMFEE CDC17P2AWW review. Have a suitable faucet? The BCD6W review explains its setup and unresolved exterior measurements.
If your round plates are 10.5 inches
This is above HAVA’s upright limit but within its published 10.6-inch angled limit. The R09 Q&A narrows that allowance to one or two angled plates. Do not interpret it as a full rack of large dinner plates. The BCD6W’s published 10-inch limit does not cover this size.
If you need to wash several 10.5-inch plates together every evening, ask about that exact load. An occasional large plate and a family’s full dinner service are different buying decisions.
If your dinner plates are 11 or 12 inches
An 11-inch HAVA fit is unresolved: its product pages give 10.6-inch angled limits, while the general US FAQ mentions 11 inches. Do not choose whichever figure favors the purchase; ask HAVA to confirm your plate and load for the current unit. Twelve inches exceeds both HAVA claims, and both sizes exceed BCD6W’s stated 10-inch limit. For Danby and the two COMFEE models, the cited loading material does not establish an 11- or 12-inch maximum.
“Try tilting it” is not enough to base a purchase on. A plate may clear the opening yet interfere with spray-arm movement or the intended loading arrangement. Ask for manufacturer confirmation tied to your dimensions, quantity and exact model. Check the seller’s return conditions before buying if this remains unresolved.
If you prefer to keep your dinnerware, leave this requirement on your shortlist. If you are comfortable handwashing a few large plates, compare how many of your other daily dishes the machine could take over; do not buy a new dinner set just to rescue an unsuitable dishwasher choice.
Plate-size evidence for six countertop dishwashers
Published limit means the manufacturer gives a size. Loading example shows a particular arrangement. Unconfirmed means our cited source does not establish a maximum. None is a hands-on fit test by Small Kitchen Notes.
| Exact model | Documented plate information | What to do next |
|---|---|---|
| HAVA R01 | Published limit: 10.2 in upright; 10.6 in angled, for round plates. Manufacturer Q&A | Check the loading arrangement near the limit. R01 buying advice → |
| HAVA R09 | Published limit: 10.2 in upright; one or two 10.6 in plates angled. Manufacturer Q&A | The newer model does not raise the stated diameter ceiling. R09 buying advice → |
| BLACK+DECKER BCD6W | Published limit: plates up to 10 in. Brand product page | Do not extend this claim to 10.5, 11 or 12 in. BCD6W buying advice → |
| COMFEE CDC17P2AWW | Loading example: two 10 in dinner plates and a 9.5 in oval platter; not a maximum claim. Manual, page 13 | Ask about a larger plate or a different mixed load. CDC17 buying advice → |
| Danby DDW631SDB | Maximum unconfirmed here: basket diagram and folding plate-rack guidance. Manual, printed page 6 | Do not convert the six-place-setting label into a diameter. Danby buying advice → |
| COMFEE CDC22P2AWW | Maximum unconfirmed here: diagram identifies dinner plates, but does not size them. Manual, printed page 7 | Confirm your largest plate with the manufacturer. CDC22 buying advice → |

Does “fits a 12-inch plate” mean your dinner set fits?
No. A maximum diameter can describe one plate at an angle. It does not establish how many fit together or leave space for bowls. Before relying on a large-plate claim, ask for the loading arrangement, quantity and exact model—not just a closed-door photograph.
| Example load you want to wash | The unanswered buying question |
|---|---|
| Two 10-inch plates, two deep bowls and two mugs | Does this mixed arrangement leave the spray arms and dispenser clear? A plate-size limit alone cannot answer. |
| Four 10.5-inch plates in one load | How many may be angled at once? Do not multiply a one-plate allowance into four usable spaces. |
| Two 12-inch plates that you will not replace | Get explicit model-specific confirmation before buying. None of our current six-model sources establishes this recommendation. |
These are planning examples, not loads we tested or manufacturer-approved rack diagrams.
When different sources give different plate sizes
Check the model code, country version, loading angle and number of plates first. If those match but the claims still conflict, keep the fit unresolved. This is why our table labels a published limit separately from a loading example. We do not turn the largest number found online into a guaranteed fit.
Once the main dish is confirmed, compare the models’ water setup and everyday tradeoffs rather than continuing to shop by diameter alone.
Turn a plate measurement into a realistic daily load
Make a short inventory from one ordinary meal: how many plates, mugs, glasses and bowls do you want washed together? Then identify the one item that could change the purchase. If the large frying pan is the chore you most want to stop doing, a good dinner-plate fit does not answer your main question.
- Compare like with like. Match your inventory to the exact manual’s illustrated arrangement. A place-setting number is not a count of interchangeable slots for cookware.
- Keep the spray path and moving parts clear. Follow the manual’s rack positions. Do not stack dishes inside each other to make a load appear to fit.
- Check the dishes’ care instructions. Size alone does not make a plate, decoration or material dishwasher-safe.
- Plan for the leftovers. If a few large items will stay in the sink, allow drying space. Our setup checklist covers optional mats and over-sink racks.
A better question to send before you buy
Copy this and fill in your own measurements. A photo beside a ruler can make a deep rim or unusual shape easier to explain.
I’m considering [exact US model]. My dinner plates are [round / square / oval], measure [outside dimensions] and have a rim depth of [measurement]. I need to wash [number] together with [bowls, mugs and glasses]. Does the manufacturer’s approved loading arrangement accommodate this load with the spray arms and dispenser unobstructed? If angled loading is required, how many of these plates fit that way?
Common plate-fit questions
Source conflict: the HAVA US FAQ mentions 11-inch angled plates, while the linked R01 and R09 product pages specify 10.6 inches. Table entries below and above report those product-page figures, not a resolved maximum.
Does a taller dishwasher necessarily fit larger plates?
No. Exterior height includes components outside the usable rack space. Use the model’s plate guidance and loading layout; do not calculate a plate limit from body height or the empty cavity.
Does the HAVA R09 fit bigger plates than the R01?
Their product pages give the same diameter ceilings; the general FAQ’s larger angled figure remains unresolved. R09’s Q&A specifically limits its largest angled plates to one or two. Read our R01 vs R09 comparison for reasons to consider the upgrade beyond plate diameter.
Can I remove the rack or force a large plate to fit?
Do not invent a loading arrangement that the manufacturer does not approve. Ask about the exact plate first. Closing the door alone does not show that the dishwasher can wash it as intended.
Once your dishes make the shortlist
There are two more purchase checks: the water connection and the space beneath your cabinets. Then use our six-model buying guide for the practical tradeoffs and current Amazon links. You should be choosing between suitable options, with a clear idea of the dishes each one will take off your hands.
