Coffee maker is extremely slow to brew; a full pot takes much longer than normal.

Safety first: Allow the unit to cool before removing the brew basket or spray head.

• Clean reservoir and inlet: Remove the reservoir and rinse it. Inspect and clean any mesh screen at the outlet with a soft brush.
• Clean spray head: Remove the OXO Rainmaker or spray head and soak it in warm water with a bit of descaling solution. Use a toothpick to clear each hole, then rinse thoroughly.
• Descale system: Run a full descale cycle according to OXO’s instructions, followed by 2–3 rinse cycles with fresh water.
• Test flow: After cleaning, run a water‑only brew and time it. If it is still significantly slower than the manual’s specification, the pump may be weakening.
• Service if unresolved: A persistently slow brew after thorough descaling suggests internal blockage or pump failure that requires professional service.
