Lubricant for gaskets of the brew unit for coffee machines

Silicone grease De'Longhi SER0354 (5 g) is designed to lubricate the seals, O-rings and moving parts of the brewing unit in automatic coffee machines. If your machine has started squeaking, creaking or emitting a high-pitched noise from the brew unit during coffee preparation, or if water is leaking around the brewing chamber, the seals have dried out and need re-greasing — this is the correct product for that maintenance task.

Important — verify your model: Before starting any service work, confirm the exact model and version of your machine on the rating plate (usually on the underside of the appliance or behind the water tank). This grease is universal for brewing unit seals and O-rings, but always follow the maintenance instructions in the manual for your specific model — some parts require lubrication, others operate dry.

When do the seals need re-greasing? (Fault symptoms)

The following symptoms typically indicate that the seals and moving parts of the brewing unit have dried out and require lubrication:

• The machine squeaks, creaks or produces a high-pitched noise from the brew unit during coffee preparation
• Water leaks around the brewing chamber, into the drip tray or from under the machine
• The brewing unit moves with difficulty, jams or requires excessive motor force to cycle
• Seals are hard, dried out or cracked, and extraction pressure has dropped

Ignoring these symptoms increases friction on compressed surfaces and can cause seals to crack, potentially damaging further components. Regular re-greasing reduces friction and significantly extends the service life of these parts.
