So … looks like this is an old conversation without a result. If anyone had any luck with a fix I’d be keen to know.
Exact same problem for me (FW version 00.11.32) had not used device for quite a few months, so could be firmware update related (I did hear it tell me something about an update from it’s dock a while back) Have checked for blockages, etc and have only ever used just cold water.
Did anyone get a response from Eufy that was helpful?
