What to do if my BUSCH Water Pump does not start?
- K
  Kathleen WardAug 28, 2025
  If your BUSCH Water Pump doesn't start, first check the power indicator light to ensure the unit is receiving power at the correct voltage by checking the power supply connection. If the power is on but the touchscreen or PLC isn't running, verify the 24V power supply. If the machine has reached a limit operating value, identify and solve the problem listed in the menu “HOME” > “WARNING/ALARM”. Also, the motor or the coupling could be defective and may need replacement.

  If the oil in your BUSCH Water Pump is emulsified, it might be because the machine sucked in liquids or significant amounts of vapour, in this case, contact Busch to flush the machine. You should also clean the filter of the gas ballast valve. Consider modifying the operational mode.

Why does my BUSCH R5 Water Pump machine fume or expel oil droplets through the gas discharge?

  Dorothy DavisSep 12, 2025
  If your BUSCH Water Pump is fuming or expelling oil droplets, the exhaust filters might be partially clogged, so replace them. Also, check the position of the exhaust filters and the o-rings to ensure they are fitted correctly. Finally, the float valve may not be working properly, so check the float valve and the oil return line, repairing if necessary.

  Rhonda FarrellAug 26, 2025
  If your BUSCH Water Pump isn't reaching its usual suction pressure, it could be due to several reasons. First, check the oil level and top it up if it's low. A partially clogged inlet screen could also be the culprit, so clean it. If your pump has an optional inlet filter cartridge, try replacing it. If these steps don't resolve the issue, internal parts may be worn or damaged, in which case you should contact Busch for repair.
