Flashing red light, lots of steam

Hi,

Our pulsa coil a class is having a problem this morning, the air cupboard is much hotter than usual and full of steam. The red light is flashing on the front panel and we've tried turning it on and off again. The top water box has plenty of water in it. The display panels under the front show a solid red line on the top left of the "DISP 2" and a flashing red dot on the bottom right of the "DISP 1".

Any advice would be appreciated.

Thanks
Emma

Sounds like a sensor problem to me.
