Electric showers should be fed with mains cold water. If you are feeding it from a tank in your roof it will not work properly. So the obvious questions are how is it plumbed and have you checked the pressure?
Otherwise check the solenoid for resistance using a multimeter. Make sure the power is OFF first though! If you get no reading replace the solenoid.
