Nespresso coffee machine flashing all its lights?

If all the lights are flashing together on a Nespresso Vertuo Plus, it usually means the machine has detected a fault or it is stuck during a start-up/reset cycle. The exact cause can vary, but there are a few sensible checks you can do first.

1. Try a basic reset/power cycle Unplug it from the mains for 10–15 minutes, then plug it back in and switch it on again. Sometimes the control board will recover if it has glitched.

2. Check the capsule area Lift the head and remove any pod. Make sure there isn’t a capsule jammed or sitting awkwardly. Also check for coffee grounds or debris stopping the head from closing and locking properly.

3. Check the water tank Remove and refit the tank, making sure it is properly seated and has enough water in it. A poor tank connection can sometimes confuse the machine.

4. Look for a blockage or scale issue If it has not been descaled for a while, limescale can interfere with operation. Clean around the injector/head area and run the manufacturer’s cleaning or descaling procedure if the machine will allow it.

5. Listen to what it does If it tries to start but only hums, clicks, or stops immediately, that points more towards a mechanical jam, pump issue, or sensor fault rather than something simple.

6. If it still only flashes That suggests an internal fault, failed sensor, or head locking problem. At that stage it is usually repair or replacement territory.

Safety reminder: isolate the appliance from the mains before inspecting any internal parts. For any mains electrical repairs, use a qualified engineer.

If you want, post exactly what the lights do, whether it locks/unlocks normally, and whether the pump runs, and that will help narrow it down.
