La Specialista pouring cold coffee, heater element the usual suspect?

how do you know if it’s scale in the thermoblock instead of an electrical issue?

If it’s scale the machine will struggle to heat the water but will still produce hot water. If it’s an electrical issue you’ll get cold water from the machine. Not a perfect rule to go by but helpful in ruling out the most common causes.

Fwiw, Mine started to produce lukewarm coffee but the unit was still producing hot water. Performed a descaling process on the thermoblock and it has returned to normal. Worth a try if you haven’t taken the time to descale your machine.

descaling can actually finish off a thermoblock that is already partially clogged. The chunks of scale will come apart and completely block the water outlet. Ask me how i know.

Yep to mine as well. After years of neglect the machine had become very clogged but after a good descaling the chunk of scale that had built up at the tip of the thermoblock was finished off. When you’re neglectful about descaling it’s better to use a gentle descaling solution instead of a strong one.
