No. It can contain electrical parts and should be assessed by an appropriately competent person. A suspected loose connection is not an owner diagnosis.
What the observation means
External indicators may help describe the fault, but they do not make internal access safe. Moisture nearby increases concern.
A useful next step
Stop connected fixture use where pumping is unreliable and report the visible state. Do not remove covers, bridge contacts or move terminals. Keep the model and control-box reference available so the service team can plan the correct assessment.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
