Siemens EQ.3 brew unit

The Siemens EQ.3 brewing unit (part no. 11041311) is a complete module in which ground coffee is compressed and pressurised hot water is forced through it. If your machine starts leaking water, coffee drips only slowly, or the cup produces a weak and watery drink, the cause is typically a worn or leaking brewing unit. This part is the correct replacement for the EQ.3 series models listed below.

Important — verify your model: before ordering, check the exact model designation and version (e.g. type code TI303503DE or the suffix after the slash, e.g. /02) on the rating label. The label is usually on the underside of the machine or behind the water tank. This ensures the part fits correctly.

When does this part need to be replaced? (Fault symptoms)

This part typically fails when you notice one or more of the following symptoms:

• Water leaks into the drip tray or directly from underneath the machine
• Coffee flows very slowly, drip by drip, or not at all
• Only water comes through with almost no coffee — the drink is weak and watery
• The spent coffee puck falls into the grounds container wet and crumbled instead of forming a firm, compact disc
