LOUD CLICKING AFTER COFFEE IS BREWED..WILL NOT STOP!

[ebayqueen]

I HAVE A SAECO EXECUTIVE AND LOVE IT. LATELY IT HAS STARTED MAKING A HORRIBLE CLICKING SOUND AFTER COFFEE IS BREWED. THE ONLY WAY I CAN STOP THE NOISE IS BY TURNING ON THE 'HOT WATER STEAM KNOB FOR A COUPLE OF SECONDS.
HAS ANYONE HAD THIS PROBLEM?
