Zanussi Condenser Dryer Model TCE 7124 W - won't stay on?

Hi,
I have the above condenser dryer. When I turn it on to a programme - I usually use A - it starts up as normal and then after about 1 minute it stops as though the cycle has finished - except that the drying light stays green instead of the two lights at the end flashing alternate green and red as it usually does when it finishes the cycle.

I got it to do a 60 minute cycle but the clothes just got hot and were still wet. But today I tried to get it to do a 30 minute cycle and it stopped after a minute with the same result above.

Now it is cycling through all the lights on the display panel.
