What it means
Siemens explains that the EQ.6 plus shows this message when the appliance has overheated, and the remedy is to switch it off for 30 minutes. The water heating system has a protection that stops the machine if the internal temperature rises too far. The message says that protection has acted, not what caused it, and it does not prove the heater has failed. Only if it returns with the machine cold or without heavy use is a fault worth considering.
