🔍 Why This Happens
Root cause analysis for your coffee maker's leaking water
The universal silicone gasket seal in your coffee maker is exposed to constant moisture, temperature changes, and chemical detergents. Rubber and silicone seals lose elasticity over time — they crack, harden, or deform, creating gaps that let water escape. Seal failures can be subtle at first but worsen rapidly once the material splits. This is the most common cause of leaking water in coffee makers.

🛡️ Prevention Tips
How to prevent your coffee maker's leaking water from happening again after this repair.
Descale the coffee maker every 1-3 months with a descaling solution or vinegar. Mineral buildup in the water line is the #1 cause of brewing failures.
Clean the brew head and needle after each use. Coffee oils and grounds accumulate and restrict water flow.
Use filtered water if your tap water is hard — minerals from hard water cause the majority of internal component failures.
Don't leave water sitting in the reservoir for days — stagnant water promotes mineral deposits and microbial growth in the system.
When installing a new seal or gasket, clean the mating surface thoroughly. Any residue on the sealing surface will prevent the new seal from seating correctly and cause a repeat failure.
