Are the Ninja DZ550 Baskets Dishwasher Safe?
Yes—the baskets, crisper plates and accessories are dishwasher safe. The smart thermometer is not, and it is the one that will cost you.

If you went looking for this on the product page, that is why you ended up here. The DZ550 listing does not mention dishwashers at all. We rendered the full page and checked: 7,316 characters, zero references. The answer lives in Ninja's support FAQ, several clicks deep, behind a collapsed section.
Ninja's exact wording
From SharkNinja's official DZ550 support FAQ, under “How do I clean the unit?”, checked 2026-07-27:
“The unit, baskets, probe and crisper plates should be thoroughly cleaned after every use. Before cleaning, unplug the unit and allow cool. To clean the main unit and control panel, wipe them with a damp cloth. The baskets, crisper plates, and other accessories are dishwasher safe EXCEPT for the thermometer. The thermometer should be wiped with a damp cloth only. Never immerse the smart thermometer in water or liquid or place in dishwasher.”
What goes where
| Part | Dishwasher? |
|---|---|
| Baskets | Yes |
| Crisper plates | Yes |
| Other accessories | Yes |
| Smart thermometer | No — damp cloth only, never immerse |
| Main unit and control panel | No — wipe with a damp cloth |
The thermometer is the part worth being careful about. It is the probe that makes the DZ550 a “smart” fryer, it is easy to leave sitting in a basket after cooking, and Ninja's instruction is unambiguous: never immerse it, never put it in the dishwasher. If it goes through a cycle by accident, that is a replacement, not a rinse.
A practical habit: pull the probe out and set it aside before you clear the table, not after. It is a two-second step that removes the only real risk in cleaning this machine.
Stuck-on food
Ninja's guidance for residue is to soak rather than scrub—the FAQ directs you to place the basket or crisper plate in warm soapy water and let it sit before wiping.
Worth knowing: RTINGS, which tested this exact model, found the ceramic-coated crisper trays harder to clean by hand than they expected. So if you have a choice on a busy night, the dishwasher is genuinely the easier path here, not just the lazier one.
While you are at it: no preheating
The same official FAQ answers the other thing people ask about this fryer. Asked “Do I have to let the unit preheat before I use a function?”, Ninja's answer is:
“Preheating is not required.”
Set your function, temperature and time, press start, and go. That is real minutes back on a weeknight, and it is another fact the product page does not carry.
Where to check the current listing
If you are still deciding, or you need a replacement part, this goes to the exact model:
- Ninja Foodi DZ550 on Amazon: confirm it is the DZ550 and that the smart thermometer is included, since it varies by bundle.
