Hi I have this model GCC 591NB when I third it on and turn it to set programme Ie: 30mins for example. I press the pause button to start all goes great then after 3 mins max the whole machine stops and no power to it. Seems to cool down after about 2 mins roughly then all the lights come back on and I can select another programme press pause button again to start and the same happens again it is only 16 months old. Can somebody help please? Thank you.
