Do you have a question about the Multi Eco and is the answer not in the manual?
Questions and answers
I have to restart the pump several times a day, the pump is working but not automatically anymore. KSB ECO
The KSB Eco pump may not be operating automatically and requires multiple restarts each day due to a failure of a duty pump. If a duty pump fails, the control unit should automatically start the next pump. However, if this fails to happen or if there are issues with the control system or protective devices not being re-installed or re-activated after maintenance, the system may not function properly. Additionally, if the pump has been out of service for over a year without replacing elastomer seals, this could also affect performance.
