Safety first: Keep the area dry to avoid slipping or electrical hazards from spills.

Reset volume (if supported): Many Senseo models allow reprogramming cup volume by holding the brew button while the desired amount is dispensed, then releasing to save.
Descale: Run a descaling cycle to ensure the flow meter spins freely and reports correctly.
Rinse cycles: Run several water‑only cycles to stabilize the flow measurement.
Service if persistent: If volumes remain erratic, the flow meter or control PCB may need replacement.

Machine dispenses too much water; cup overflows compared to normal volume.
