What does Err – 204 mean on my Water Right Impression Plus?
- GgatesmichaelSep 5, 2025
If your Water Right Water Dispenser displays Err – 204, it means a leak has been detected. This occurs when the dP input is active for “ALARM” and the input is closed. The alarm buzzer will activate, and the screen will display the error. Check for a low flow leak. Press the NEXT and REGEN buttons for 3 seconds to resynchronize the software with the piston position, or disconnect the power supply from the PC Board for 5 seconds and then reconnect to clear the error.
