I am getting an error code on my new 13000 DC Jebao pump- controller reads ER04- (impeller or controller issue). Straight out of the box & I’m already having instant bad luck:face-with-spiral-eyes: Any suggestions on how to troubleshoot this and get it working? I checked to make sure everything is plugged in properly and there isn’t anything obstructing the impeller so I’m not too sure what could be wrong.
