Give the symptom, affected fixtures and any leak or electrical concern through the property's agreed reporting route. Avoid naming a failed component as certain.
What the observation means
The responsible person may need to authorise work and arrange access. Continued use can worsen an overflow even while a report is being considered.
A useful next step
Stop affected fixture use where drainage is unreliable and make the safety concern clear. Do not buy parts, open the unit or alter pipework without the proper arrangements. Keep existing observations and any warning message available for the person assessing it.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
