Safety: Do not open the external transformer; replace it if faulty.

Check outlet: Plug another device into the outlet to confirm power is present.
Inspect adapter: Ensure the Ecowater power adapter is firmly plugged into both the outlet and the control head.
Try another adapter: If available, test with a known-good adapter of the correct voltage and polarity.
Board inspection: If there is still no display, the internal fuse or control board may have failed and should be replaced by a qualified technician.
