🔧 Product Overview

The thermoblock boiler is a key heating component inside DeLonghi espresso machines. It rapidly heats water to the correct temperature required for brewing and steaming.

Over time, scale buildup, electrical wear, or internal heating element failure can cause poor performance or complete heating failure. Replacing the thermoblock restores safe and reliable operation.

🔍 How to Find the Correct Boiler for Your Machine

To ensure you order the correct thermoblock boiler for your DeLonghi machine, please check the identification code stamped on the base plate of the existing boiler.

• Look for the code Ø6 stamped near the centre pipe connection area of the boiler (check 4th picture if applicable).
• If your boiler has the Ø6 marking, then this 5513227881 thermoblock is the correct part for your machine.

⚠️ If you can find no code stamped on the boiler, it typically indicates the unit is Ø6 type.

☕ Why Replace Your Thermoblock Boiler?

A faulty thermoblock can severely affect machine performance. Replacing it will:

• Restore correct brewing temperature
• Fix heating and steam issues
• Improve coffee quality and consistency
• Prevent further internal damage
• Extend the lifespan of your coffee machine

🔧 This thermoblock contains two internal heating elements, and each element typically reads approximately 82.5 ohms resistance when tested correctly. This is an important diagnostic indicator for technicians.

⚠️ In many cases, the smaller heating element fails first, causing the machine to produce lukewarm coffee even though it appears to operate normally.

This resistance pattern is commonly used by technicians to confirm thermoblock failure.
