Why is my Danfoss Series 42 system operating hot?
- J
  Johnny YoungJul 28, 2025
  If the Danfoss Water Pump system is operating hot, several factors could be the cause. First, check the oil level in the reservoir and fill it to the correct level with clean hydraulic oil. If equipped with a heat exchanger, ensure proper airflow and input air temperature, cleaning, repairing, or replacing it if needed. Also, verify that the bypass valve is fully closed and seating correctly, repairing or replacing it if necessary. Check the SCR valves to ensure they are seating properly and at the correct relief setting, repairing or replacing them if needed. Inspect the oil filters to ensure they are operable and replace them if necessary. Finally, ensure the machine operates within its design parameters, reducing the load if required.

  A sluggish response in your Danfoss Water Pump system can stem from several causes. Begin by checking the reservoir oil level and fill it with clean hydraulic fluid as needed. Next, verify that the input signal is correct and consistent in both directions. Inspect the pump control for proper operation, ensuring the control spool isn't damaged or worn and moves freely; clean, repair, or replace it if necessary. Ensure the bypass valve is closed and seating correctly; clean, repair, or replace it if needed. Lastly, check the SCR valves to ensure they operate freely; repair or replace them as necessary.
