What to do if KSB Controlmatic E.2 pump does not stop when closed?
- MMr. Travis ChangAug 10, 2025
If your KSB Control Unit pump continues to run even after closing all consumer installations, the issue might be due to severe leakage in the system. Inspect the shut-off valves and piping, and repair any leaks. Also, the flow detection might be prevented by sand or other solids blocking the check valve. Disconnect the unit from the mains supply and flush it through to remove any solids.
