On January 19, 2025, I purchased a Canaan miner—the Avalon Mini 3—from the online shop "mineshop.eu," paying €1,003.85. The miner/heater was delivered to me by the shipping company on April 22, 2025. Since then, I had been using it to heat my home office (approx. 17 m²) on cool days while hoping to find a block via solo mining.
In late May 2026, I noticed that the device was emitting little to no heat. The hashrate was negligible or non-existent. Upon being switched on, it would briefly ramp up before entering a sort of emergency mode, operating at only one-tenth of its capacity and no longer serving as an effective heater. I first contacted the retailer, who referred me to the manufacturer. I then exchanged several emails with Canaan’s support team (
support@canaan.io). Initially, I was asked to try restarting and resetting the device—steps I had already attempted myself, to no avail. Subsequently, I was instructed to download a diagnostic tool from the company’s website (
https://www.canaan.io/support/file_download) and extract the operation log files, which I then had to upload to the support page. Finally, I was informed that the unit was defective and that I would need to ship it—at my own expense—to an authorized repair center in Portugal for a paid repair. Canaan refused to honor any warranty claims, asserting that the device's warranty had expired on April 17, 2026.
Consequently, I contacted the online retailer in Ireland (mineshop.eu) again, citing European consumer protection laws, which mandate a two-year statutory warranty obligation for retailers. The retailer refused to handle the matter and referred me back to the manufacturer. When I persisted and demanded that he honor the warranty, he stopped responding. On June 5th of this year, I also submitted a support ticket via the retailer's website (
https://mineshop.eu/contact-us – "Open RMA Request"), which the retailer still refuses to process.
The legal situation regarding this is clear: Under the Irish Consumer Rights Act 2022 / Statute of Limitations and the European Rome I Regulation (Art. 6), the retailer is obliged to honor warranty claims for two years from the date of delivery. In Ireland, the warranty period is actually up to six years. This Irish online retailer, "mineshop.eu," refuses to fulfill this obligation and consistently ignores my requests to do so.
I have always used the device carefully and strictly in accordance with its intended purpose, so I am not responsible for the defect. What can I do now? Does anyone have any ideas? Does anyone happen to know someone here in Germany who could take a look at the "Avalon Mini 3" device and potentially repair it?
Best regards,
Rai
