What it means
In its EQ.6 plus display message list, Siemens says "Error - please contact hotline" means the appliance has a malfunction, and the solution it gives is to contact its service. Unlike other messages on the list, such as cleaning the brewing unit or letting the machine cool, there is no user step here. The message does not say which part has failed: only service diagnosis can confirm it, so parts should not be replaced on a hunch.
