This ice cream maker is suitable for all MUM5 machines.

Hello Emily. I cannot help you with the sizes, because the bucket is in our holiday home now, but i have very good experience with the swiss Bosch service. I sent them my question in english, and received an answer in 1 day! Try them: ch-spareparts@bshg.com. good luck!

Yes, the supplier has confirmed that the products are suitable.

Put the whole block in the freezer (-20°C) for at least 18 hours before making the ice cream or sorbet. Then you can make your recipe; if you don't use the ice cream right away, pour it into another container; don't leave it in the cooler. At least that's what I read in the instructions and I can confirm it because I've already tried the product. Without it, it doesn't work.

Bosch only states compatibility with the MUM5, so it is not suitable for the Bosch Optimum.

Hi, I have a MUM54230/01, this ice cream maker is compatible with the MUM5. I have 3 children, so it's ideal for the 4 hours 😉

I say yes. For everything bosch mum 5. your xw 20 is newer with a scale. So the bowl plug connection should be the same.

The manufacturer does not seem to provide any information on this, and unfortunately I did not find any other precise answers to your question. But I suspect not.

Yes, everything is included.
