Dodgy Bread Machine

Gerry has a bread machine he has never used.  This weekend I tried it.  It did all the kneading and proofing, but when it tried to bake, it tripped the electric circuit, and it did not blow the fuse, very strange.  I had to reset the circuit as soon as I found out, so the fridge will not defrost.  I will probably not use the machine again...
