- If it works:
- overheating was the cause.
- If the message remains:
- go on to clean the brewing unit.

What it means
Siemens explains that on the EQ.6 plus, "Please restart appliance" appears when the machine is overheating or the brewing unit is fouled. These are two different causes the control sums up in one message: the appliance temperature above normal, or a brewing unit that does not complete its movement because of coffee residue. The Siemens solution is to let it cool and clean the brewing unit. The message does not prove a fault; if it returns with the machine cold and the unit clean, service is needed.
