MODEL-SPECIFIC QUICK ANSWER
JURA ENA 4 NAA blinking lights and common signals
On the ENA 4, the water-tank symbol means the tank is empty, while alternating first and third symbols mean the system needs filling. Slow drip coffee can result from a grind set too fine; adjust the grinder as directed and descale when the machine’s maintenance symbol requests it.

What “verified” means: Each listed signal or symptom is tied to a linked manufacturer source. This is guidance, not a diagnosis of an internal fault.
