Kenwood Titanium Timer Chef KMC030 mixer intermittently turns on

When I press the on button my mixer sometimes turns on, but sometimes all that happens is an audible click of the solenoid and nothing else happens. This mostly happens after the mixer has been running for over a minute and I stop it to add an ingredient then try to switch it back on but nothing happens. Because the issue most often happens when the mixer has been running I was thinking it was because of a thermal protection circuit, but after taking it apart I can’t find anything. Any help would be appreciated.

Edward Swash if you still have it apart, any chance you can add some pictures of what you are looking at with your question? That way we can maybe assist you a bit more. Could be the switch or could be the motor etc. Adding images to an existing question
