Cap for DeLonghi PrimaDonna Avant coffee machines

What is a cap/seal plug and what it's for

A cap or seal plug is a cover or blanking piece that seals a chosen point of a coffee machine's water or heating circuit. It keeps water or steam under pressure at that point and prevents it from escaping the intended path. Without a properly seated and undamaged cap, the system cannot reliably maintain the pressure needed to brew coffee.

How to spot wear

• Dripping or leaking water or steam at the cap
• Pressure drop and weaker, watery coffee
• Error messages relating to pressure or heating
• Moisture or limescale build-up around the part

Why timely replacement pays off

A damaged or brittle cap gradually lets water through, which can corrode nearby metal parts and put extra strain on the heating element. Timely replacement prevents a bigger fault and extends the life of the whole circuit.

How to choose the right part

Caps differ in shape and size between coffee machine models, so check the compatibility table on the product page before purchasing.
