I have emailed EcoFlow but have not gotten a response from their website Support. I have reached out via FaceBook groups, Twitter, etc. and have gotten no response from anyone having this issue or any kind of corrective action. We have had our Delta 2 since we ordered it back on Dec 28, 2022 and it has worked flawlessly until this past week. I did register the unit on EcoFlow website when I got it so not sure what the warranty is.
