I was descaling my 8 year old gaggia coffee today and noticed something disturbing. The polyproplene tube that comes off of the self priming valve was quite hot. It has also turned white-ish for the last 5 cms from the bottom which sits in the water reservoir.
Is this normal or a sign of the dreaded stuck pea valve? Any assistance would be greatly appreciated.
