Hover Tumble Dryer E 14 Error

I bought a Hover dryer about 2 months ago. From the first time I turned it on, the machine had a timer problem. It shows that it will finish in 1 minute, but it doesn't stop even after 1 or 2 hours. We reported the issue to the technical service, and they said these machines have a chronic brain problem. They said they would change the motherboard when it arrives. They came and changed it after a whole month, but this time it gave an E14 error, and they took the machine saying it couldn't be fixed here... As a result, I still haven't been able to use the device that I paid for 2 months ago. Absolutely avoid it, don't even take it for free, customer service is a total disaster, you can't talk to anyone, it's not like a customer representative, it's like a neighborhood bully, probably they're overwhelmed like me and because they don't face any consequences, they're extremely relaxed... If writing this post leads to any consequences for them, I'm ready to share all kinds of documents and information. Finally, I went to the seller, and the seller said if it hasn't been more than a month since you bought the device, they definitely can't even touch it with a screwdriver, they should change it immediately...
