12V AC Power Adapter
The most common failure point is the mechanical seating of the regional prong attachment on the power brick. If the locking mechanism is not fully engaged to the detent, the spring-loaded pins fail to bridge the primary circuit, preventing the battery from charging or the unit from receiving mains power. This leads to a total system non-start condition once the internal battery reaches critical discharge.

Main Control PCB
The user interface relies on momentary tactile switches mounted to the logic board. Physical failure of these switches or micro-corrosion from humidity/milk vapor can cause an 'open' signal path, where the microcontroller never receives the interrupt signal to begin the pumping sequence. If the LCD functions but buttons do not respond, the trace continuity or switch mechanicals have failed.

Internal Lithium-Ion Battery
The S1 Plus utilizes a rechargeable Lithium-ion cell. Over time, internal resistance increases or the cell can enter a deep-discharge state where the battery management system (BMS) permanently disables the discharge path for safety, rendering the unit unresponsive unless connected to a high-amperage power source.
