Whatsminer M21S fault-- NEED HELP

[adam020798]

Hi im new to the mining community and ive recently bought 2 Whatsminer M21S's. They were both tested before being shipped (Well known company) but when ive set them up they run for 10-15 minutes then restart. Theyll do a cooldown after restarting before mining again and then do the exact same thing again. They both have the exact same fault, ive swapped control boards about along with hashboards and at one point i had it running for 25 minutes all going well but now theyre stuck in the same look again without me changing anything. ive tried rumerous different things but cant figure it out. Can anyone help?

This is the log at the point of restart

1- please use code tag to insert any sort of logs

Code:

start Example of logs


End

2- what you posted shows nothing wrong, you need to export logs from Whatsminer tools, it has all the details needed to troubleshoot the miner.

Furthermore, at the button of the status page, any errors will be displayed you just get the error number and then google it to find out what it says.

And most importantly, some of them take up to 45 mins to tune, so give them at least an hour, if you reboot them mid way they will start over.

[BitMaxz]

The only error that I could see on the logs you provided is "Restart as hashrate error" and then "system power off".

I would like you to try to change the pool first into solo.ckpool.org and see if the miner won't restart.

If the issue persists do what Mikeywith suggested above to get the error codes or use the Whatsminer tool it should give you error codes if the unit is running abnormally.

You can download the tool from this link below then go to the tools tab.

Hi, thanks for your reply’s. There are no fault codes showing in the Whatsminer too, I’ve also tried 2 different pools but get the same result. I thought it was just tuning at first but I’ve had it running for 2 h+ and get the same result, just a constant loop I’ll get the logs off Whatsminer tool and post them. Running out of ideas tbh

If my suggestion does not work would you mind to try to replug all fan cables and power supply since it just recently arrived there's a possibility that there may be a loose connection between the power supply and the controller or there might be a loose screw on copper row, 6 screws should be tightened and copper bar should be aligned properly to avoid some issues.

Check the manual beliw on how to dismantle this unit and replug the PSU.

Yeah I have already tried that, thought the same. I’ve had them both disassembled when changing the washboards around. Everything is tight and plugged in properly. Also tried reinstalling the firmware maybe there was a glitch but still the same. Also tried bixbit firmware but that’s the exact same.

Well if you did all the basic things and it still doesn't work they sent you a defective unit or possibly the delivery guy didn't handle it with care during delivery.

Would you mind telling us what company you bought this unit?
If it is still under warranty then better send it back to where you bought this unit for replacement or repair warranty.

[adam020798]

The company was CoinMiningCentral. I don’t believe it’s a defective unit as I bought 2 off them and they’re doing the exact same, it just keeps coming up with restart due to hashrate error. I’ve only had it a couple times run properly while I’ve been trying to sort it but can’t get it to consistently run as it should. It comes to the point when it normally restarts and irons out the hashrate and instead it just cools down and repeats the cycle.

I thought you solved your issue? Do you still have this unit?
If still have not solved your case I suggest try to change the network type from DHCP TO Static and leave the IP the same only adding DNS you can use GoogleDNS or Cloudflare DNS because I believe your ISP is blocking any mining-related like pools.

You were supposed to post the logs you got from Whatsminer tool, but you have not, anyway, here are two things to do

1- Check the input voltage to your miner, lower voltage would cause the miner reboot loop
2- Unmount two of the hashboards and leave only one, try a random order, keep the right board, and if it fails, keep the middle or left.

report your results here and I will help you further.

Sorry about that, here is the end of the system log of the miner. Ive had to trim the top of the log because of maximum character length. Full log is here https://www.mediafire.com/file/etmqa49rnx915v9/system.log/file

The input voltage is 240V AC just after the plug in the power supply and the voltage to the hashboards is 13.9V DC.
Ive tried multiple different hashboard combinations and still get the same result, it will run with just 2 hashboards (any 2) but when all 3 are connected i get stuck in this restart loop.
Thanks for your reply Mikey, any help is much appriciated

The last log is pointing to chip temp calibration it fails and the following logs is keeps waiting to the board to cool which is weird.

I heard someone before with the same issue but on Whatsminer m20s but he solved the issue by changing the pools.

You are still using Braiins pool according to the logs and I don't know what pool you tested before would you mind to try again changing the pool but this time use https://solo.ckpool.org/
Please use this while you are troubleshooting.

Would you mind changing the performance mode to saving mode if it still does not? Use whatsminer tool to change it from normal mode into saving mode you can find it under the control button. Let's see if it would run normally let it run first for 30 minutes and then update here.

[adam020798]

Afraid to say I have already tried both of those 
Would it be better for you to see the logs with these settings?
I’ve also tried running BixBit firmware on the lowest underclock possible and was the same.
I’ll run it with those settings again tho and get a log for you.
Thanks

Your fans are bad, maybe you installed them in the wrong direction? they should be reading above 7000rpm but yours doesn't go above 3000, here is the log from one of my working whatsminer

as you can see the fans are spinning at 7k+ range, takes less than a minute to cool the board down to 34.8, and then the miner goes to the next stage, so i'd check both fans and make sure they are blowing in the same direction.

[adam020798]

Hi Mikey, i also thought the same so i tried running it with an external AC infinity fan and putting the miner in immersion cooling mode on bixbit but still have the same result. I've just bought a new PSU so gonna try that now

[philipma1957]

I WOULD try a different controller

Not sure the PSU is going to fix it, I doubt it, but anyway, your problem is not very common, I played with hundreds of M21s before, never faced a similar issue nor any of the clients I have sold M21s to, you can speak directly to Oliver on telegram, he is an official Whatsminer tech support guy and he would certainly be able to help you better, you may just need to wait a while before he responds given that he is always busy.

This is his telegram https://t.me/whatsminersupport

Would appreciate it if you keep the topic up to date so others can benefit from it.

Thanks Mikey I’ll send him a message now, will report back when I find a solution. Thanks for the help

[mikeywith]

Not sure if you stated this piece of info but I couldn't find it, many people miss doing one of the basic tests which is running the miner with only 1 hashboard using two different hashbaords one at a time, in many cases the issue is just within a single board which causes the whole miner to act crazy, obviously, since you may be so unlucky and test the bad board only, you are required to test at least two out of the three hashboards you have, this basic troubleshooting process will reveal a lot of information.

[adam020798]

Hi Mikey, yeah I’ve already tried that. No matter which boards I use the miner will only run with 2 boards in. Any 2 of the 7 boards I have it will run normally. But as soon as I add a 3rd board it does the reboot cycle. Ive spoke to Oliver at whatsminer and he’s told me the miner has been tampered with, the label on the case isn’t original. Not sure exactly what’s been tampered with but I’ve tried 3 different control boards, numerous variations of hashboards out of the 7 and I’ve just got a new PSU that I need to try. I’ve also contacted coinminingcentral again after finding out the label isn’t original, their reply was that it’s a USED unit and that it was all tested before shipping to me. I mean I understand there’s no guarantee with a used unit but one with unoriginal parts?? Would never buy a used unit off them again. Their support was ok trying to help me, trying different test to figure it out but they’ve since cut me off basically, they’re no longer replying to me.
