Main PCB Assembly
The filter reset function requires the microcontroller to register a continuous 'closed' circuit from the interface button for approximately 7-10 seconds. If the tactile dome switch on the PCBA develops high contact resistance or the internal timer on the IC fails, the cumulative hour-counter in the EEPROM will not be cleared. This hardware failure leaves the unit in its terminal maintenance state, causing the red LED to persist even after new filtration media is installed.
