What to do if the red LED is on and BWT Medo XB4 Water Pump stops?
- JJessica GuzmanJul 26, 2025
If the red LED indicator lights up and the BWT Water Pump stops, it could be due to a low liquid level in the storage tank. Refill the storage tank. Alternatively, if an external cable is connected while the multifunctional switch is not set to "Extern," either switch to "Extern" or disconnect the external cable.
