This machine came with but one problem. It was noisy with fair bit of hum.
Upon opening I could see that nobody was there before me, immaculate original condition, completely unmessed with. Nice and clean outside and in. The hum problem was caused by loose harness. There is a harness which needs to be strictly routed on the side and it’s held in a plastic clip. This clip was originally attached using double sided tape which dried out and the clip detached.
So this was literally 1 minute repair job. The only other thing to do was to clean the pots and blow out the dust.
