    Why is there no water in the boiler of my LAVAZZA LB 2810 Coffee Maker?
    • J
      Jason ValenzuelaSep 3, 2025
      If there's no water in the boiler of your LAVAZZA Coffee Maker, first check if the valve of the water mains is closed and open it. If the valve is open, the pump filter might be clogged, requiring replacement. Also, check the power pump to ensure it is connected and not blocked. A damaged water inlet solenoid valve may also be the cause, necessitating its replacement. Lastly, the filter of the water inlet solenoid valve may be clogged; clean or replace it.

    • B
      Barbara HernandezAug 31, 2025
      If your LAVAZZA Coffee Maker is dispensing coffee too quickly, it could be due to an injector with a diameter that is too large; replace it with one of a smaller diameter. Alternatively, the boiler temperature might be too high; reduce the temperature in the boiler.

      If the coffee dispensed by your LAVAZZA Coffee Maker is too slow, the injector of the brewing unit might be clogged; try replacing it. Alternatively, the brewing unit itself could be clogged; check and clean it. Also, inspect the capsule-holder for dirt and clean it. If the lower perforators are dirty, clean them and replace them if necessary.

    Why there is no electrical power on my LAVAZZA LB 2810 Coffee Maker?
    • D
      Diana MckeeAug 26, 2025
      If your LAVAZZA Coffee Maker has no electrical power, ensure the on/off switch is in the “I” position. If it is already in that position, the switch itself might be damaged and need replacement. Also, verify that the network switch is in the ON position. Finally, check for any defects in the electrical network connection.

    What to do if my LAVAZZA Coffee Maker does not dispense?
    • C
      Charles JohnsonAug 25, 2025
      If your LAVAZZA Coffee Maker isn't dispensing coffee, first ensure there's water in the mains. If water is available, the issue might stem from a defective solenoid valve in the brewing unit, requiring replacement. Alternatively, the pump could be jammed, necessitating its replacement. A burnt-out fuse in the control unit could also be the culprit; replace the solenoid valve protection fuse (1A). Other potential causes include a clogged injector (clean or replace it), a clogged or dirty brewing unit solenoid valve (clean or replace it), or a jammed flowmeter (check/replace it).

    Why is my LAVAZZA Coffee Maker leaking water?
    • C
      Casey AguirreAug 23, 2025
      If your LAVAZZA Coffee Maker is leaking water, first check the sewer drain to ensure the drain tray is discharging correctly. Next, inspect the drain pipe for breaks, detachments, or clogs, and restore its connection to the drain tray. Finally, check the hydraulic circuit for water leaks and eliminate them.
