Symptoms
- Machine makes brewing sounds but cup stays empty or nearly empty
- Short stream of water then stops
- Grounds visible around the needle area
- Error message about water or priming
Likely causes
- CommonClogged entrance or exit needleCoffee grounds and oils build up around the needles that pierce the pod, blocking flow.
- CommonMineral scale blocking internal water linesHard water buildup restricts the narrow tubing over time.
- PossibleReservoir not seated properly or low on waterA misaligned reservoir can prevent the machine from drawing water.
- PossibleAir pocket in the water lineThis can happen after refilling the reservoir from empty.
- Less commonFaulty water pumpPumps can wear out after years of regular use.
What to do
- Turn off and unplug the machine, then remove and refill the water reservoir completely.
- Open the pod holder and clean the exit needle with a straightened paper clip, and the entrance needle with a small brush, following the manufacturer's cleaning guide.
- Run a few cycles of plain water without a pod to clear air pockets and flush debris.
- Run the machine's built-in descaling cycle using a commercial descaler or vinegar-water mix if it hasn't been descaled in the last 3 months.
- Check that the reservoir is fully seated and its valve isn't obstructed.
- If water still won't dispense after cleaning and descaling, the internal pump has likely failed and the machine typically isn't worth repairing.

When to call a pro
If descaling and needle cleaning don't restore water flow, the pump has likely failed; replacement is usually more cost-effective than repair for these machines.
