| Cleanig Test Dishwasher Safe? Series 9 |
“Easy to clean” can mean several different things. It may mean that a machine has removable parts, that selected parts are dishwasher-safe or that the cooking bowl can run a short pre-cleaning cycle.
None of those claims necessarily means zero cleanup. Grease can remain on a lid, food can collect around a blade, and ingredient containers may occupy more dishwasher space than expected.
This comparison examines the real cleanup workflow for Posha and Thermomix TM7—and separates dishwasher-safe components from the powered sections that must remain out of the sink.

Quick Verdict
Posha: The cooking pan and four ingredient containers are described by Posha as dishwasher-safe. However, multiple containers, the pan and the stirring component still create a noticeable cleanup load.
Thermomix TM7: The mixing bowl, lid, mixing knife and accessories are dishwasher-safe, while a built-in pre-cleaning function can loosen food before washing.
The TM7 places more food preparation inside one main bowl, but its blade, lid and accessories require careful disassembly. Posha avoids a blade inside the cooking pan, but its ingredient-container system creates more separate pieces to load and wash.
1. Dishwasher-Safe Does Not Mean Maintenance-Free
A dishwasher-safe part can tolerate an approved dishwasher cycle, but the user still has to remove it, empty leftover food, separate components and load them correctly.
After the cycle, some parts may need drying before reassembly. Seals, corners and deep containers can retain water. Heavy sauces or cooked-on starches may also require rinsing before the dishwasher cycle.
The powered base, display, electrical connectors and motorized sections of any cooking appliance must never be submerged unless the manufacturer specifically states otherwise.
Always follow the current manual for your exact model. Product designs and approved cleaning methods can change.
2. Cleaning Posha After Dinner
Posha’s cooking system includes a removable cooking pan and four ingredient containers. The company describes the pan and containers as dishwasher-safe, with the containers designed to be stackable and refrigerator-friendly.
This is useful because the parts that directly hold most ingredients can be removed from the machine. The cooking surface does not have an integrated high-speed chopping blade that must be cleaned after every meal.
However, autonomy creates additional components. A typical cleanup may include:
- The cooking pan
- Used ingredient containers
- The stirring tool or food-contact component
- Spice or oil residue near dispensing areas
- Splashes on the interior and surrounding surfaces
A published hands-on review also noted that Posha requires washing the containers, pan and spatula or stirring component, while the robotic arm itself is handled differently.
The number of parts depends on the recipe. A simple dish may use fewer containers, while a meal with several timed ingredients can create a fuller dishwasher load.

3. Cleaning the Thermomix TM7
The Thermomix TM7 concentrates chopping, mixing and cooking inside its 2.2-liter mixing bowl. That reduces the need for separate cutting devices, mixing bowls and pans for compatible recipes.
According to Thermomix and Vorwerk guidance, the mixing bowl, lid, mixing knife and relevant removable accessories can be cleaned in a dishwasher. The appliance’s powered base and touchscreen must remain outside the dishwasher and should be wiped according to the manual.
The TM7 also provides a pre-cleaning or self-cleaning mode. Water and a small amount of detergent can be added to the bowl so the machine agitates the mixture and loosens food residue.
This is best understood as a pre-cleaning function—not a guarantee that the bowl, blade, lid and seals will always emerge ready for storage without inspection.
Sticky dough, oily sauces, caramelized ingredients and food trapped around the knife assembly may require additional attention.

4. What Goes in the Dishwasher?
| Component | Cleaning method | Practical note |
|---|---|---|
| Posha cooking pan | Dishwasher-safe | Remove food and heavy residue first |
| Posha ingredient containers | Dishwasher-safe | Up to four containers may require space |
| Posha powered body and arm | Do not submerge | Wipe only as directed by the manual |
| TM7 mixing bowl and lid | Dishwasher-safe | Separate and inspect seals and edges |
| TM7 mixing knife | Dishwasher-safe | Handle carefully and clean separately |
| TM7 accessories | Check accessory instructions | Varoma and other parts add dishwasher volume |
| TM7 powered base | Do not submerge | Wipe with the method stated in the manual |
5. Which Machine Creates More Separate Parts?
Posha may create more separate food containers because ingredients are loaded for timed dispensing. The benefit is hands-off cooking; the tradeoff is that several containers may need washing afterward.
Thermomix TM7 can process many ingredients in one bowl. For a simple soup or sauce, cleanup may remain relatively compact. A multi-level family meal can add the lid, simmering basket, Varoma dish, tray and other accessories.
The better system therefore changes by recipe:
- Simple soup or sauce: TM7 may create fewer pieces.
- Posha one-pot meal: Pan plus the used ingredient containers.
- TM7 multi-level meal: Bowl, lid, knife, basket and Varoma parts.
- Sticky dough or thick paste: TM7 may require detailed blade-area cleaning.
- Oily curry or tomato sauce: Either machine may need pre-rinsing.
6. The Dishwasher-Space Test
A component can be dishwasher-safe and still be inconvenient. Large pans, deep containers and steaming trays may displace the plates and cups from the same family meal.
Compact-dishwasher owners should measure the rack before purchasing. Households without a dishwasher should pay even more attention to part count, corners, seals and blade access.
A useful test is to imagine cleaning the machine at 9 p.m. after a long working day. If every component must be washed immediately to prepare the robot for breakfast or the next dinner, cleanup becomes part of the daily ownership cost.

7. Five-Minute Cleaning Routine
- Remove or serve the food before residue dries.
- Disconnect removable food-contact components as instructed.
- Scrape leftovers into food waste rather than the sink.
- Use the TM7 pre-cleaning function or briefly rinse removable Posha parts.
- Load approved components securely and wipe the powered body separately.
Do not force water into motors, connectors, vents, sensors or the touchscreen. Do not assume that every accessory is dishwasher-safe simply because the main bowl or pan is.
8. Which Is Easier to Clean?
Posha may feel easier to users who prefer a conventional pan and removable ingredient containers. Its dishwasher-safe pan and four containers simplify routine washing, but they occupy space and still require unloading and drying.
Thermomix TM7 may feel easier for one-bowl recipes, especially when pre-cleaning loosens food before the parts enter the dishwasher. However, the blade, lid, seals and multi-level accessories make manual cleaning less attractive for households without a dishwasher.
Neither product eliminates cleanup. They reorganize it: less stovetop mess and fewer conventional pans, but more appliance-specific components.
Final Verdict: Dishwasher Ownership Changes the Result
For households with a full-size dishwasher, both systems offer a manageable cleaning workflow. Posha provides a dishwasher-safe pan and ingredient containers, while the TM7 offers dishwasher-safe removable parts and a useful pre-cleaning mode.
Without a dishwasher, the TM7’s blade and accessories or Posha’s multiple containers may become more noticeable. The easiest choice is the appliance that matches the meals you cook most often and the cleanup system already available in your kitchen.
A robot chef should save more time than it creates. Count the dirty parts, not only the automated cooking minutes.
