Is my main module assembly faulty?

Hi my Beko WM5140W washing machine is only filling water for about 2-3 seconds when starting any cycle, then stops. if the power button is turned off/on then it starts filling again but for 2-3 seconds and stops. If this is repeated it gets to the required water level and stops filling. After turning the power button off/on the motor starts turning then stops after 2-3 seconds and repeats every time the the power button is pressed. Any help would be appreciated.
