Whatsminer Error Code Guide
Whatsminer is a reliable miner when managed properly. Since miners run 24/7 for years and are constantly exposed to high heat, it’s very important to maintain proper temperature and keep the environment clean. Repair costs usually start from around $150, so it’s always better to take care of your machine before issues get worse.
Below are some of the most common Whatsminer error codes, with explanations of what they mean, the possible causes, and recommended solutions.
