Keep the exact light, message or sound pattern and stop adding wastewater. The alarm's meaning is model specific.
What the observation means
A warning may concern a level, operating state or accessory, and silencing it does not resolve the cause. Some systems have a separate alarm device.
A useful next step
Follow the owner's alarm instructions and arrange assistance if normal safe operation is uncertain. Do not repeatedly flush to test the alarm or disconnect its speaker so fixtures can remain in use. Provide the unit and alarm references when available.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
