The declaration names a part, not a machine
The parts that go in are the ones the maker names. On this site:
- Yes: the blades of the KitchenAid KSMVSA slicer, “on the top rack”; the Dash Mini Maker plates, “right into the dishwasher”; the Emile Henry ceramic pizza stone.
- No: the Presto sealing ring — “Is Dishwasher Safe No” — and the KSMPRA pasta roller, “Hand Wipe only”.
None of them says the appliance is dishwasher-safe. That distinction is the whole subject.
Never, on anything
The body of any appliance with a motor or electronics in it. The KitchenAid glass scale is hand wash only — the glass is fine and the electronics under it are not. A waterproof rating does not change that: the ThermoMaven thermometer is IP67 and still hand wash only.
Never, on these parts
Pasta rollers and anything with gears. Water sits in the mechanism and rusts it; the KSMPRA ships a brush for exactly that reason.
Porous stone. The Unicook and the Ritual Life cordierite stones both forbid detergent — a porous stone absorbs it and gives it back to the next pizza. The Emile Henry is the exception: its maker states it dishwasher-safe, on a proprietary ceramic rather than cordierite.
Pressure cooker rings. Heat and detergent are what harden an elastomer; a hardened ring stops sealing. Wash it by hand, with the groove it sits in — see cleaning a sealing groove.
A frozen ice cream bowl. The KSMICM bowl is washed by hand in warm soapy water, once it has reached room temperature — never straight from the freezer.
The gray area: coated plates
Several makers declare their coated plates dishwasher-safe; several are silent. Where a maker is silent, hand wash is the safe reading — a dishwasher’s detergent is considerably harsher than dish soap, and it is what shortens a coating’s life. More in nonstick coatings, and what kills them.
The rule
Check the manual for your specific model, and treat a maker’s silence as a no. Nothing on this page overrides the document that came in your box.
What readers want to know
Is stainless always dishwasher-safe?
Not automatically. What matters is the declaration for that specific part. The KitchenAid KSMPRA pasta roller is stainless throughout and stated "Hand Wipe only" — water inside the rollers rusts them, and wet dough in the gears is worse. The KitchenAid glass scale is hand wash only too, because of the electronics under the glass.
Is waterproof the same as dishwasher-safe?
No. The ThermoMaven HT04 is rated IP67 — it survives immersion — and its listing still says hand wash only. An IP rating is about cold water for a short time; a dishwasher is hot water, alkaline detergent and a drying cycle for an hour.
Which parts are usually excluded?
Anything with electronics, anything with a motor, anything with rollers or gears, porous stone and most rubber seals. Where a maker publishes a declaration, it names the part rather than the machine — and where it is silent, read the silence as a no.
