Whatsminer event code E011

I have a whatsminer M3 working for the past 2 months with no problems at all, but yesterday it started acting strange since it is restarting every 15 minutes, all temperatures are fine between 80 to 85deg celsius, and I noticed that there is an event with the following data

Event: code E011
Event cause: Slot-0 Zero HS 1620 seconds
Event action: Zero HS warning
Event count: 3
Event source: System-monitor

I have searched everywhere but I couldn't find anything, I also contacted Pangolinminer to no avail.

I really appreciate any help.

Thanks in anvance

Charles
