Hi. My Bosch Classixx 1000 has been a solid performer for nearly 20 years. But, it's now developed a fault.
it's clear that it's a PSU problem on the main board caused by water ingress onto the board. The PSU uses a TOP209P, a three terminal Off-line PWM switch. That may be faulty so I have ordered a new one. However, the more difficult issue is that the transformer in the circuit has an open circuit on one of the windings. This component might be hard to repair (but not impossible). I wish I could source a new transformer, but what the chances of that I don't know. There are markings
