Both fuses are changed to 15 amp. A 240v circuit is two 120v circuits (legs, L1 & L2) working together, each half takes the same size fuse or breaker, whatever required size that may be.

It's not OK to upsize fuses or breakers on a circuit that's smaller than needed because the wire may be too small to carry the higher current safely.

But it is OK to downsize fuses or breakers ... actually it's required or the appliance involved won't be properly protected. The wire was installed large enough to carry the original higher level of current (40 amps) so can safely carry the lower current (12 or 15 amps). Sounds like you don't have much experience with electrical so I'd strongly suggest hiring an electrician to do the job.

Either or both fuses or breakers on a 240v circuit may blow or trip, depending on the nature of the electrical fault.

Short of disassembling the machine, best you can do for cleaning the interior is run a cycle with liquid chlorine bleach (IF Miele allows it), or a commercial washer-cleaning product such as Affresh or Tide Washing Machine Cleaner.

I don't have direct experience with Miele, but my understanding is that parts are available only from them, or perhaps if there's a given item on eBay, and the cost is typically high.

I cleaned the drum of my grandma's Miele by running it on the longest and hottest cycle with citric acid. Then caught the wash water in a bucket, switched the washer over to spin and poured the hot solution into the spinning machine. Another rinse and some water down the dispenser during the subsequent spin will clean out any residue from the cleaning cycle.
