  Victoria SmithAug 11, 2025
  If the Ecolab Water Pump Mikro-Master 300 is not operating, first check the power source to the pump. Then, ensure the Internal - OFF - External switch on the pump is in the External position. Also, check for water flow through the system and correct as necessary. Inspect the interconnecting cable between the flow meter and the pump to ensure it is connected properly. Make sure that water flow through the system is more than 1 gpm. Finally, ensure the programmable divider's plastic window is properly installed and tightened.

  If the Ecolab Water Pump does not stroke, make sure that the Internal - OFF - External switch on the pump is in the External position. Also, adjust the divider number on the programmable divider to a lower dosage ratio. If the issue persists, the flow meter or the pump may be faulty and require replacement. Check the interconnecting cable between the flow meter and pump to ensure it is properly connected.

  Henry WoodAug 25, 2025
  If the Ecolab Water Pump strokes too fast (more than 80 strokes per minute), the divider number of the programmable divider is likely set at a low dosage ratio number. To fix this, set the divider number up.

Why Ecolab MIKRO-MASTER 300 will not pump against system pressure?
- B
  Brianna SullivanSep 4, 2025
  If the Ecolab Water Pump will not pump against system pressure, it may be due to improper installation where the system pressure exceeds 70 psi (4.8 bar). To resolve this, install a pressure regulator to the Mikro- Master 300 system.
