Softener emits a persistent beeping or alarm tone without a visible error code

Safety: No special safety measures beyond normal electrical caution.

Steps:

• Check menus: Navigate through the information and service menus for any maintenance reminders or warnings.
• Verify salt level: Ensure the brine tank has adequate salt and no bridging.
• Power cycle: Turn the unit off for 1–2 minutes, then back on. If the alarm persists with no visible cause, consult the service manual for hidden diagnostic codes.
• Technician check: A stuck buzzer or internal fault may require PCB replacement.
