Daikin NDJ Smart Premix Combi Constantly Fails With J6-01 Error
I purchased a Daikin NDJ Smart Premix combi from Daikin’s own website, and the device has been causing constant problems for the last 2 years. It will be 3 years in 2 months since we bought it, and for about 2 years we have been experiencing frequent malfunctions. We have to call service at least twice a year, and the issues vary, but the most frequent one is the J6-01 error code. Despite repeated service visits, the problem keeps recurring and the combi does not work reliably. This situation has caused us serious financial and emotional damage. A Daikin customer service representative told me that when I explained the situation, engineers would examine the combi and that if it was defective, it would be replaced. However, nothing like this happened and the product that has been malfunctioning constantly since the day we bought it has never been changed. In addition, the teams that come for service not only demand payment on every visit, but also generally state that they do not have an invoice system, and therefore I have never been given any invoice or proper documentation after the visits. I have called Daikin customer service many times, written through the complaint section on Daikin’s website, and submitted several complaints on Xolvie, but I have not received any satisfactory or permanent solution, and most of the time I did not even get a proper response. I live in Kaynarca, Sakarya, and I continue to experience the same problems with this combi. Considering the continuous faults over a long period, the recurring J6-01 error, the lack of proper documentation from the service teams despite charging fees, and the financial and psychological distress this has caused, I request that my Daikin NDJ Smart Premix combi, which I bought from Daikin’s official website, be completely replaced with a new and fault‑free device. I kindly ask for a permanent solution and a clear response as soon as possible.
On May 18 we got in touch and Ms. Simlay created a complaint record. On May 20 a person from the authorized service came, tinkered inside my boiler and left it in a faulty condition. As he left he said the team was on its way and that a more specialized team would arrive at my house within half an hour. When I reported the situation to customer service they reached the authorized service team, and on the morning of May 21 Ms. Simlay said they would provide service within the day. No one showed up that day. On May 22 I contacted customer service again and explained the situation to Ms. Gurbet. The authorized service was contacted again and they told me I would receive service on May 23. When no one came on May 23 I called customer service again and this time explained the situation to Ms. Dilek. Ms. Dilek said she had reached the authorized service and that I would receive service that day and that I should have no doubt about it. Yet again no one from the authorized service came, and they never informed me that they would not be able to come. On May 24 I called customer service to say that nobody had come to my house and I spoke with Ms. Dilek. When I said that my house still had not been visited, she was very surprised and said that the authorized service would be reached on Monday morning, May 25. On the morning of May 25 I had not received any response from anyone and, fed up with waiting for the authorized service at home, I called customer service again to get information on whether they would come. I told Mr. Metin about the conversation from the previous day and he said that the authorized service had been called and would come within the day, and if they had not arrived by lunchtime they would be contacted again. Around 15:40 I called Mr. Metin and he was also surprised that they still had not arrived. He reached the authorized service and they got back to me. At 15:40 they told me they would come within the day. They said I was delayed because they came from another district. They said they did not come because my complaint record was marked as an emergency and it was far away. They said they did not come because they were very busy on Saturday. How far the service team has to travel does not concern me as a consumer. According to Daikin’s records, my boiler has officially been broken for eight days. Daikin has left me without a boiler for eight days. If my boiler is not repaired today or tomorrow, I will enter the holiday without hot water at home. After eight days without hot water, unable to bathe, I will not only spend the holiday like this but also have no hot water during the holiday. This is a deliberate act of consumer victimization. I expect an apology and an explanation from Daikin for everything I have experienced.
