Grind method: If you grind at home, using a burr grinder will help you achieve a better brew (blade grinders can create too much dust). This dust, along with grind inconsistencies can create a higher density within the capsule, essentially contributing to blocking the capsule, resulting in excess water leaking into the drip tray.
Grind size / tamp: A grind that is too fine can also result in excess water leaking into the drip tray. We suggest experimenting with pressure - pack the coffee more loosely with minimal tamp, or simply fill and screw on the lid.
Lid: Experiment with the interchangeable Steel Filters. If tamping less hasn't assisted in resolving the excess water in you drip tray, switch to a filter with more slots.
Pump function: We also suggest making sure your coffee capsule machine has been recently cleaned, descaled and is in optimum working condition. “Descaling” is the act of stripping calcium and lime deposits from your machine’s surfaces, assisting the pump to create a pressure build-up that produces a lovely crema to top your brew. If you want to ensure your coffee machine is producing the best flavour and an optimal brew pressure, it should be cleaned once a week and descaled once every three months. Cleaning your coffee machine not only extends it's life, but also ensures the quality of the coffee you brew. Tip: Don't - Use vinegar! Vinegar doesn't remove coffee oils the way a professionally formulated coffee machine cleaner does. Do - Use a cleaning solution that will remove oils, stains and break down grime.
Gaskets: If the gaskets are damaged or missing, the position or pressure to the capsule might be affected.
Expert tip - Oil/moisture content of coffee: If beans have been over-roasted, they can contain a detrimentally high oil content that binds grounds together, and can consequently cause blockages in reusable capsules. If you experience this with your favourite coffee brand, we suggest chatting to your local roaster about this occurrence or experiment with switching to a medium roast.
