Before applying the Stiebel Eltron 16 meaning, confirm the affected model uses the WWK service and fault-code display. In that controller namespace, 16 means documented as an impressed-current anode short circuit or faulty protective anode.
The STIEBEL ELTRON WWK 222/302 Operation and Installation Manual source anchor on page 15 supports this Stiebel Eltron 16 record for the WWK service and fault-code display.
