Probable Causes (ranked)

Fix Steps

  1. 1 Collect and weigh 10 fills — determine if consistently over/under or random
  2. 2 Clean fill nozzles — disassemble and flush
  3. 3 Check product temperature — viscosity affects fill volume
  4. 4 Inspect piston seal or pump diaphragm — replace if worn
  5. 5 Reduce fill speed if foaming or splashing
  6. 6 Calibrate level sensor in product hopper

Field Trick

If fills are consistently low, check the nozzle for buildup. If fills are random high/low, check the pump seal — it's probably leaking air.
