Despite emptying the bottle the red light remains on and the dryer refuses to heat but everything else seems to work. Thanks.

Same thing has happened to mine before.
The most likely thing is the thermostats in the back have gone.
I have found them at

http://shop.ukwhitegoods.co.uk/product_info.php?products_id=78

The thermostat kit is p/no. 1701583, and is only £12.00.

I bought some from somewhere that was advertised on this site last time, but not sure how much i paid for them, and they have lasted about a year now before they have gone again and i am just about to buy some more. Hopefully they will last a little longer this time.
