TEFEL STEAM IRON MODEL GV 9150GB/23-28-05?

I AM AN ELECTRICIAN AND HAVE REPLACED THE MAGNETVALVE PART NO. CS-00095084 BECAUSE THE VERY SMALL FILTER HAD BROKEN OFF INSIDE THE BOILER UNIT. NOW COMPLETED THE IRON MAKES ALL THE RIGHT NOISES AND THE ACTUAL GETS HOT, BUT THERE IS NO STEAM COMING FROM IT. AND IT WOULD APPEAR THAT THERE IS NO WATER BEING DRAWN INTO THE HEATING CHAMBER.
