Why is my Puretec SOL40-E3 valve display blank?
- RRussell GuzmanAug 20, 2025
A blank screen on your Puretec Water Dispenser valve can be due to several reasons. It could be that the transformer isn't connected, there's no power at the outlet, the outlet is switched or providing improper voltage, the battery is dead, the transformer is defective, or the PC board is defective. To resolve this, ensure the transformer is connected, use a working outlet or repair the existing one, use an uninterrupted outlet and ensure proper voltage, replace the battery (CR2032), replace the transformer, or replace the PC board.
