My mother's water heater in Agios Dometios has stopped working properly and needs to be fixed. It isn't producing hot water as it should, and I'm not sure whether the issue is with the heating element, thermostat, or something else. I'd like a qualified technician to come out, diagnose the problem, and carry out the necessary repair. Please let me know what information you need from me before scheduling the visit.
