Report "Hi i have a DeLonghi ESAM3500 and has two PTO's on heater. I discovered that the bottom one was open circuit so ordered another one :) I turned it back on and all started happily after 4 minutes it went back to generic alarm. i measured bottom PTO and was open circuit. when was working hot water was comming out before failed and heater element measures aroung 48 ohms. could someone shed some light on this for me :) Kind Regards, Cameron"
