Thermomix food processor blades and parts by part number

The rubber sealing ring that sits under the mixing knife's bearing, stopping liquid getting from the bowl into the motor. Thermomix Australia sells one Blade Seal for the TM5, TM6 and TM7 and says to replace it if it is damaged or lost. A new Blade Knife Set already comes with one. The manuals say never use the knife without the ring, and check it for damage.

After the change: No reset.

Fits 3 Thermomix models: TM5, TM6, TM7.

Thermomix's own replacement mixing knife for the TM6 and TM7. Thermomix Australia sells one Blade Knife Set for both machines, with a blade seal included. The TM6 and TM7 manuals say the knife wears with hard food: replace it every 2 years with weekly ice crushing or flour milling, every 6 months if daily, or every 4 years if hardly ever. Don't sharpen it. It does not fit the TM5.

Change it every 2 years; 5 steps, no tools.

After the change: No reset: Thermomix has no knife reminder.

Fits 2 Thermomix models: TM6, TM7.

Thermomix's own replacement mixing knife for the TM5, with a blade seal included. It is a different part from the TM6/TM7 knife: Thermomix says the TM5 and TM6 knives and bowls are not interchangeable. Thermomix gives no replacement interval for the TM5 knife; replace it when it is worn or damaged. Thermomix Australia says it will service the TM5 until February 2029.

After the change: No reset: Thermomix has no knife reminder.

Fits the TM5.

The green silicone ring that seals the TM31 mixing bowl lid. Thermomix says to use the TM31 only with the green ring, replace it every two years or sooner if it is damaged, and stop using any grey ring. TM31 production ended in 2014 and Thermomix Australia no longer has other TM31 parts, but says the green ring stays available.

Change it every 2 years; 4 steps, no tools.

After the change: No reset.

Fits the TM31.
