smeg sa663x?

Hi,
Our Smeg SA663X had a burning electrical smell. Now it will go through a full cycle, fill with water, heat etc and drain. However, there is no washing action at all! Very little noise and not a lot happening at all. I am a technician in the printing industry, so more than capable of a more than DIY fix, looking for some pointers or known issues to save me some time and diagnostics. Haven't pulled it out yet, will do it on the weekend! Any advice would be appreciated!
