SMEG ECF01 coffee maker repair - pressure relief water return valve fault

Suddenly only very little water was going into the cup. The fault was with pressure relief valve that was returning most of the water from the pump back into the water tank. In the video I showed the main coffee maker parts and how to assemble them together. I did not show replacing the valve itself but all it requires is just taking the silicone tubes off it and unscrewing the valve from the top of the water pump. I also did not show disassembly - it is exact reversal process of putting all back together. Maybe it helps someone.
