5213225251 Genuine Flowmeter for De'Longhi Coffee Machines, DeLonghi Water Flow Sensor for Coffee Volume Control

A flowmeter counts the water passing through a coffee machine, and 5213225251 is De'Longhi's genuine version of that part. The control board uses its signal to measure each cup, so a fault quickly shows up in the coffee volume. No compatible model list is on file for this number. Match it against the part number on your old flowmeter, or send us your De'Longhi model number and we'll check before you order.

When a De'Longhi coffee machine pours the wrong amount

Inside the flowmeter is a small impeller that spins as water passes through. A sensor counts each turn and sends pulses to the control board, which works out how much water has gone through. When scale or coffee residue jams the impeller, or the sensor fails, the board loses track. You might see cups that overflow or come out short, a pump that runs on and on, water that stops mid cup, or a water circuit error. Regular descaling helps prevent it.

Fitting the new flowmeter

Switch off, unplug and allow the machine to cool before removing the covers. Take a photo of the flowmeter's hoses and its wiring plug so they go back the same way, paying attention to the direction of flow. Replace any perished hose clips or seals while it's open. When finished, prime the water circuit and run a few test cups to check the volume is right.

Questions about this part

Will descaling fix a flowmeter fault?

Sometimes. If scale has only slowed the impeller, a thorough descale can bring it back. If the impeller is stuck, the housing is cracked or the sensor has failed, replacing it with 5213225251 is the fix.
