miele coffee machine fault codes

If your Miele coffee machine is not heating properly, produces lukewarm coffee or never reaches brewing temperature, the cause is often a simple maintenance issue rather than a major fault. Scale build-up, restricted water flow or a machine that has not completed its warm-up cycle are common reasons. This guide explains the most common causes of heating problems and the checks you can safely carry out before arranging a repair.
