Problem on a Hotpoint WD420 Aquarius washer/dryer

My wife went to run a program the other night and when she started it she realised it was the wrong one. Instead of stopping it and restarting she just turned the dial to the one she wanted. After she done that the machine went crazy and lights started flashing and the machine no longer will run a program. After doing what hotpoint advised which was return the dial to the original program this still doesn’t work. I have also tried the usual of turning off at the mains and leaving it a while. But when I turn it back on I still get flashing lights. The lights that flash are the on/off light, the hight heat light and reduce creases light. Does anyone have an idea what might be wrong? Thanks for any help offered.
