Direct answer
On the covered GE water softener, Blue indicator light flashing means GE states a steady blue light means the softener is working correctly, and a flashing light means it needs attention. GE lists the causes as interrupted power, a Present Time setting that needs checking, controls that need reprogramming after an outage, a flashing Days to Empty (add salt), or ERR in the display (an electrical problem). First, read what else is flashing alongside the light — Days to Empty and ERR mean different things.
Definition versus diagnosis
The display names a detected condition—not an automatically failed part.
What this covers
- GE water softener covered by the cited source
- Displayed code or documented alias: Blue indicator light flashing
- The exact operating state described by the manufacturer
What it does not cover
- ×Another product type or original-manufacturer platform
- ×A visually similar but different code
- ×Internal live electrical, sealed-system, gas, battery-cell or control-board repair

Preserve the failure state
ReversibleRead what else is flashing alongside the light — Days to Empty and ERR mean different things. Record the operating stage, recent change and what still works before clearing the message.
Correct only the documented fault domain
ReversibleAdd salt if Days to Empty is flashing; reset the time and reprogram the controls after a power outage; treat ERR as the electrical fault it is. Do not borrow a reset or meaning from a similar code, product or model year.
Verify once, then respect the service boundary
ReversibleRepeat only the shortest safe action that reaches the original stage. If Blue indicator light flashing returns, stop repeated resets and use model-specific manufacturer support.

Common follow-ups
What does Blue indicator light flashing mean on a GE water softener?+
GE states a steady blue light means the softener is working correctly, and a flashing light means it needs attention. GE lists the causes as interrupted power, a Present Time setting that needs checking, controls that need reprogramming after an outage, a flashing Days to Empty (add salt), or ERR in the display (an electrical problem).
Can I reset Blue indicator light flashing without fixing the cause?+
A reset may hide the display temporarily but does not correct the documented fault. Record the code and complete only the safe checks first.
Why is the complete model number required?+
Manufacturers reuse characters across platforms. The model number determines which official table, controls and service boundary apply.
When should I stop?+
A flashing light with ERR is a service condition. A flashing light with Days to Empty is just salt.
