Dyson V15 Detect Still Shows "Airway Blocked" After Paid Repair

I purchased a Dyson V15 Detect vacuum cleaner, and due to a motor failure I have been constantly receiving the “Airway Blocked” warning during use. Although it was clear that the problem was not caused by the filter, after a video inspection your customer service insisted that I purchase a new HEPA filter. Trusting Dyson’s assessment, I paid TRY 1,500 for the filter, but the problem remained exactly the same. After this, I followed Dyson’s paid repair process. My vacuum was collected from me in Izmir, Turkey on 18 June 2026, and I was charged TRY 6,500 for the repair, which I paid immediately as requested. Despite this, my vacuum has still not been repaired. For the first 10 days, I was repeatedly told that my vacuum was at the service center. However, on the 17th day I found out that it had never even arrived there. Instead of Dyson investigating the situation, I had to contact the courier company myself. The shipment records show that the vacuum was only delivered to the service center on 6 July 2026. Since then, more than 15 business days have passed without any solution. Despite my repeated calls, I always receive the same response that “your device is under maintenance,” and I am not given any clear information about the status of the repair or when my vacuum will be returned. As of 24 July 2026, there has been no progress and I have been left without a vacuum cleaner for weeks, which has seriously disrupted my daily life. I did not expect such an incompetent and misleading service process from a brand like Dyson. The serial number of my product is U3B-EU-SDE4415A. I formally request that Dyson immediately and properly repair my Dyson V15 Detect vacuum cleaner and return it to me without any further delay. If this is not possible, I demand either a brand-new replacement device or a full refund of the product price, together with reimbursement of the TRY 1,500 HEPA filter cost and the TRY 6,500 repair fee that I have already paid. Otherwise, I will file a complaint with the Turkish Consumer Arbitration Committee and pursue all available legal remedies. After this experience, I will not purchase another Dyson product again.
