Soon as i set cycle and swich on door light flashes open

Hi,
The cycle doesn't advance
When the cycle doesn't advance, it's probably the timer or a cold-water supply problem:

It's the timer, if your washing machine fills with water and begins agitating, but the timer never advances--or if the washer is in a spin cycle and the timer won't advance. Then you need to replace the timer. 


It may be a cold-water supply problem, if the washing machine fills with water, agitates, drains, and spins, but then doesn't fill with rinse water. See There's no cold water.

Thanks for your question.
