If this fails, the water tank warning lamp will light up red. It will not turn off even if you fill the water tank. Now, This MK04U is an easy-to-understand sensor among the Magnifica models, which tells the board whether the float in the water tank is floating or not. First, check if the float in the water tank is not inserted upside down. It's OK if the circle mark is facing up. This is rare, but check if any nails or other objects are attached to it as it should have magnetism. For the following models: ECAM series, EAM series, ESAM series, can be used for all ECAM series.
