Windscreen washer not working when engine on

When the car is on ignition the washer works fine but the wipers stay on and done go off. When I engine is turned on the washer doesn't work but the wipers come on as normal and then go off. The light washer works fine. Also if the pump was faulty or fuse gone then it wouldn't work when the car is on ignition

It's a long shot but check your door switches. Washer is disabled if door is open, and perhaps door condition is checked only if engine is on?

It's all fine. Now when I sprayed the windscreen (car in ignition) the wipers came on very slowly and stayed in the middle (water came from the nozzle as normal) then I started the engine and the wipers went down and worked as normal but the washer didn't work.

Junaid, Did you change your wiper motor recently? or do you know if it was ever changed? Check through Star diagnosis on status of Wiper motor.
