DeLonghi dc - Recent Questions, Troubleshooting & Support
Delonghi DCU72 refused to heat on 6th use.
I have the same problem.
Being an electrical engineer, I would like to debug the circuit card.
However, I would like to brew coffee also.
I disassembled the bottom of the coffee maker, and unscrewed
the bracket holding the circuit card.
I cut the input power and ground wires from the plug to the card, and detached its modular wire to the heating element.
I removed the card
(to take to lab for further debugging).
Then I bought some .25 inch modular tab connectors at the hardware store and attached one to the power wire formerly going to the circuit card. I attached this to the heating element.
I covered the spare ground wire with electric tape.
Now I have a coffee maker which brews coffee again (except that I must pull the plug to shut it off).
If I figure out what is wrong with the circuit card, I will update you.
