i have been experiencing the same probs graham. my cousin, who has his own repair service told me to do the following, and its crucial timing
1. switch washing machine off and wait for door to click
2. turn dial to stop at the end of the cotton programme and switch on. the light will flash quickly - switch off IMMEDIATELY it does this.
3. do the same on the synthetics programme.
4. do the same on the delicates programme.
this reprogrammes the computer in the washing machine.
5. then run on a 90 degree wash. it should then work. mine does. good luck
