HELP How can I fix my Hoover HNL662 Washing Machine?

If you start any cycle it stops and the start and delay start lights flash intermitantly and the cycle stops. Its still draining water (if it gets that far). We've replaced the sensor as that had been suggested as a possible problem but that hasn't changed anything. HELP - I've not had a washing machine for over a week!! Can't afford a new one so desparate. THankyou
