Philips AquaTrio 9000 Series - E5 Error and Unresponsive Customer Service

On August 7, 2024, I purchased the Philips AquaTrio 9000 Series device via Hepsiburada, specifically because the seller was Hepsiburada itself. Despite already having a well-known and trusted brand of vacuum cleaner at home, I chose this product due to its mopping feature. On the night of June 24, after completing a full vacuuming and mopping cycle, the device finished its cleaning mode and was placed on the charger. The following evening, when I unplugged it to vacuum my pet's bed, it displayed an *E5 error*. Upon researching the issue, I discovered this error indicates the battery is not seated properly.However, the battery was inserted on the day of purchase and has *never been removed since*. How can a device suddenly give a battery seating error if the battery has never been touched?I contacted your WhatsApp support line and explained the entire situation in detail. Yet the only response I received was: *“You are receiving this error because the battery is not seated properly.”* This explanation is simply *unacceptable*. How can a battery that was inserted only once and never removed suddenly become "improperly seated"? Additionally, customer reviews about Philips service—especially in Bakırköy and Bahçelievler—are full of complaints, with people waiting 3 to 4 weeks for service. If I had seen these beforehand, I would have never purchased the product.The device, which is under warranty until August 6, 2029, is already being referred to service *within the first year*, without any misuse or external cause.Now I’m being asked to bring the product to a service center, which, given the known delays and poor experiences, is a *complete disappointment*. I strongly advise others to read Philips service reviews before making a purchase.
