  David KingJul 27, 2025
  A 'ZERO FILTER FAULT (0100)' in your Bacharach Measuring Instruments indicates contamination in the purge air. This could be due to dirt, water, or refrigerant in the charcoal purge filter, meaning the charcoal filter may need replacement. Also, ensure the purge line has a filter on the end (line end filter p/n 3015-3420) and that the purge air comes from a clean, dry source.
