This component is essential for the proper functioning of the appliance, specifically responsible for detecting the amount of water in the tank. Designed for the Delonghi models listed at the bottom of the page, it ensures that the coffee machine correctly interprets magnetic signals, preventing sudden blockages or false alarms during coffee dispensing.\u003cbr\/\u003e\u003cbr\/\u003eFeatures and Technical Data\u003cbr\/\u003e- Original Delonghi spare part\u003cbr\/\u003e- Country of manufacture: Made in China\u003cbr\/\u003e- Color: white\u003cbr\/\u003e- Connector type: JST 2 pin female\u003cbr\/\u003e- Resting contact position: normally open (NO)\u003cbr\/\u003e- Printed codes on the product: MEDER MK04U-BV15279\u003cbr\/\u003e- Equivalent or discontinued codes: 5213216041, 5213216841\u003cbr\/\u003e\u003cbr\/\u003eMeasurements\u003cbr\/\u003e- Cable length: 23cm \/ 230mm\u003cbr\/\u003e- Total length: 26.5cm \/ 265mm\u003cbr\/\u003e\u003cbr\/\u003eWhat is it and what does it do (General Info)\u003cbr\/\u003eBut what exactly is a Reed Sensor? It is a magnetic switch that reacts in the presence of a magnetic field. In bean-to-cup coffee machines, it is mainly used for two purposes: to detect the presence of the water level (interacting with the magnetic float in the tank) or to monitor the position of the brew group (encoder\/transmission). Without this small device, the motherboard does not receive the necessary information to allow the coffee preparation cycle.\u003cbr\/\u003e\u003cbr\/\u003eSymptoms and Diagnostics (Q\u0026A)\u003cbr\/\u003eQUESTION: Why does the low water indicator light turn on in my Delonghi bean-to-cup coffee machine?\u003cbr\/\u003eANSWER: First, make sure that water is present and that the black magnet moves correctly; you can easily recognize it, as it is a float located at the bottom of the tank inside its own housing that rises and falls based on the water level. Also, check that the tank is intact; there is usually a plastic tab that, if broken, does not allow the coffee machine to detect the presence of the tank. If the problem persists after these checks, it may be caused by a faulty reed sensor.\u003cbr\/\u003e\u003cbr\/\u003eQUESTION: How do I check if the reed sensor is faulty?\u003cbr\/\u003eANSWER: The check is very easy: remove the sensor, place a magnet above it, and use a tester to check the electrical continuity in the two JST connector pins. If the electrical circuit is closed, then the sensor is functioning; if it is open, the sensor definitely needs to be replaced.\u003cbr\/\u003e\u003cbr\/\u003eExpert Tips and Maintenance\u003cbr\/\u003eTo extend the life of your new Delonghi sensor, it is important to understand why these components fail. The number one enemy is moisture. Even though the sensors are insulated, internal condensation or small water leaks can oxidize the electrical contacts or the small internal glass bulb.\u003cbr\/\u003e\u003cbr\/\u003eTechnical Advice: When replacing part 5213217891, ensure that the plastic housing where it is inserted is perfectly dry. Never clean the sensor by immersing it in water; use only a dry cloth or a dry electrical contact spray. This electronic spare part does not require active maintenance but must operate in a dry environment to last for years.\u003cbr\/\u003e\u003cbr\/\u003eInstallation Instructions\u003cbr\/\u003eReplacing this component requires a minimum of manual skill and DIY ability. The difficulty can be rated as 6\/10. Follow these simple steps:\u003cbr\/\u003e1. Ensure that the coffee machine is unplugged and cold.\u003cbr\/\u003e2. Remove the three outer covers and take out all removable accessories (tank, waste drawer, lid, etc.).\u003cbr\/\u003e3. Look for where the water tank is positioned; underneath or to the side, you will find the reed sensor.\u003cbr\/\u003e4. Disconnect it from the electronic board and unscrew any screws (if present) that hold it in place.\u003cbr\/\u003e5. Proceed with the replacement, being careful to position the wiring correctly.\u003cbr\/\u003e\u003cbr\/\u003eNot what you are looking for?\u003cbr\/\u003eIn addition to the Reed sensor, we have many original Delonghi accessories and spare parts available in our store.
