No. An indicator and a motor can have different control paths. A visible light does not establish why the unit is failing to start.
What the observation means
The activation condition and warning state also matter. Do not add repeated water to force a response from a suspect system.
A useful next step
Stop using connected fixtures and report the displayed state and original event. Leave electrical and internal testing to a competent person. Do not tap the casing, bypass a switch or feed power directly to the motor.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
