Dewert / Bosch motor failure
Koinor (founded 1980, Ebersdorf bei Coburg, Bavaria) builds its recline systems on German Dewert and Bosch linear actuator motors - with Limoss units on select models - all rated for European load cycles and stable 230V supply. Indian voltage fluctuation and continuous daily use accelerate motor failure at year six to twelve. One seized motor locks the entire recliner function - backrest, leg rest, headrest tilt all stop. Owners sometimes attempt a power reset, which can damage the control board. Early diagnosis prevents board failure. Read more on recliner mechanism repair.
