A normal household mop can introduce water near plugs, sockets or control equipment. Keeping the floor clean does not make those parts water-safe.
What the observation means
The actual installation may have exposed low-level electrical fittings. Do not move the pump or pull cables to gain cleaning access.
A useful next step
Use a safe method consistent with the equipment's instructions and keep electrical areas dry. If they become wet, do not touch or restart them; obtain appropriate help. Tell the service team about the event if operation changes afterwards.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
