Kenwood breadmaker not heating

Technical_Dave

I have a Kenwood BM258 breadmaker which has recently stopped working. On any program, it runs for a few minutes then beeps and the display returns back to 'SEL', which is the program selection stage. At no point does it seem to heat up, which I'm sure it did fairly quickly before.

I suspect that there is something not quite right with the heating element, or control of the heating element, which the machine realises and resets the program.

I'm quite happy to take it apart, have a poke around and replace parts, but haven't opened up a breadmaker before so I'm not too sure what to expect. From a bit of googling, the parts I'm thinking are relevant are the heating element (obviously), the thermister assembly and the twin thermal fuse assembly.

So, has anyone ever taken a bread maker apart, if so do you know what all of the above parts do, and more importantly how to go about testing them?

I have a multimeter. And 9" grinder just incase it all goes horribly wrong.
