WILLOW WILLOW 360 (GENERATION 3) Wont Turn On

Willow 360™ / Generation 3 Replacement Pump (Single)

The motor unit contains the non-serviceable Lithium-ion battery and logic board. Failure to power on typically indicates a bricked BMS or a failed micro-tactile power switch that has lost its mechanical spring-back due to membrane fatigue. Since the housing is a sealed environment to maintain vacuum pressure, the entire motor unit must be replaced.

Willow Power Charger

The Willow device requires a specific voltage handshake to initiate charging. If the internal pins of the charger or the charging port itself have oxidized due to moisture exposure (common in milk expression environments), the unit will fail to charge, eventually leading to a complete power-on failure once the residual battery capacity is exhausted.
