SMEG Coffee Maker Error Lights & Alert Guide (DCF02, ECF01, ECF02)

SMEG Lights Mean Different Things on the Drip and Espresso Machines

SMEG coffee machines don't show numbered error codes. They talk through lights, and the same colour means different things on different machines. On the DCF02 drip filter coffee machine, a red dot under the clock means it's time to descale. On the ECF01 and ECF02 espresso machines, the descale warning is an orange light on the steam button, and the most serious signal, all lights flashing and the machine not working, means unplug it and call a SMEG service centre.

Find your machine below. The drip machine has a clock display and a glass jug. The espresso machines have a filter holder with a handle and a steam knob on the side. SMEG bean-to-cup machines (BCC series) aren't covered here, because we haven't read their manuals; use the one for your exact model.

SMEG Lights at a Glance

Try This First

• Drip machine: check the tank has water, then look for the red dot under the clock. That's the descale reminder, and you can still brew while it shows.
• Espresso machine: close the steam knob. An open knob is the first cause SMEG lists for the two coffee lights flashing.
• Push the water tank fully into place and check it has water.
• Wait for the lights to stop flashing after switching on. Flashing in sequence at start-up is just heating.
• ECF02 with all keys orange: press the programme-change key to go back to the White Menu. It isn't an error.

DCF02 Drip Coffee Machine Lights

The DCF02 has an ON/OFF button with a light, AROMA, 4 CUPS and AUTO START buttons, and a clock display.

The DCF02 has no error codes. SMEG's troubleshooting table only covers coffee not coming out (no water, or scale), slow brewing (scale), only water coming out (no ground coffee) and overflowing. The earlier DCF01 works the same way.

Descaling the DCF02 (Red Dot)

The red dot comes on automatically, based on the water hardness you set.

1. Pour water and a descaler recommended by SMEG into the tank, up to the maximum level, using the amount the descaler's maker recommends.
2. Put the empty jug with its lid on the Keep Warm plate.
3. Hold ON/OFF and AUTO START together for 5 seconds.
4. Wait. When it's finished, the display goes back to the clock and the red dot disappears.
5. Run a rinse cycle with fresh water and no coffee.

If the red dot comes on too often (or not often enough), set the water hardness: hold AROMA + 4 CUPS for 3 seconds, choose SE02 with the lever, then HA01 (soft), HA02 (medium, the default) or HA03 (hard).

Our SMEG descaling guide has the full procedure, and our SMEG won't brew guide covers the drip machine's other causes.

ECF01 and ECF02 Espresso Machine Lights

ECF01: three buttons on top: one cup and two cups (white lights), and steam, which lights orange when it's time to descale.

ECF02: keys (20), (21) and (22), plus a programme-change key (23). It has two menus, so the key colours change:

All keys orange means you're in the Orange Menu. Press key (23) to switch back to white. The only orange warning is the steam key (22) flashing orange, which asks for a descale.

One-Cup and Two-Cup Lights Flashing for a Few Seconds

SMEG's troubleshooting tables list these causes:

Too Hot After Steaming: Cool Down the Boiler

After frothing milk, the boiler is too hot for coffee. On the ECF02 the two coffee keys flash alternately to show it. SMEG warns that coffee made without cooling down "will taste burnt".

1. Put a container under the steam wand.
2. Open the steam knob. On the ECF02, steam comes out first, then hot water. Watch out for the steam.
3. When hot water flows (ECF02), or once it stops coming out (ECF01), the boiler has cooled.
4. Close the knob and make your coffee.

Descaling the ECF01 (Orange Steam Light)

1. Fill the tank with water and a SMEG-recommended descaler, following the pack.
2. Switch on, remove the filter holder, and put a container under the frothing nozzle.
3. Wait for the one-cup or two-cup lights to go steady.
4. Hold the steam button for 10 seconds, until the three buttons flash in sequence.
5. Turn the steam knob to the steam position and press the steam button to start.
6. When the cycle stops, the orange light flashes. Empty and rinse the tank, refill it to the maximum mark, and put an empty container under the nozzle.
7. The rinse runs until the tank is empty, and the orange light goes off. Turn the steam knob back.

During both cycles, close the steam knob now and then so some liquid also runs through the boiler outlet.

Descaling the ECF02 (Key 22 Flashing Orange)

The warning shows every time the machine comes out of standby until you descale.

1. Empty the tank, remove any water softener filter, and fill to MAX with water and descaler as the maker directs.
2. Remove the filter holder. Put containers under the dispenser and the steam wand.
3. Switch on. When it's ready, hold key (22) for 10 seconds until its orange light is steady.
4. Open the steam knob and press key (22) to start. It flashes while it works.
5. When the tank is empty, key (22) lights white. Rinse the tank, fill it to MAX, and press (22) again to rinse.
6. When the tank is empty again, the machine is ready. Close the steam knob.

Use SMEG-recommended descaler on both machines. Neither manual mentions vinegar.

All Lights Flashing and the Machine Won't Work

This is the one SMEG signal with no owner fix. On both the ECF01 and ECF02, "the coffee machine does not work and all lights flash" means a possible fault, and SMEG's instruction is: "Unplug the coffee machine and contact an Authorised Service Centre."

Don't confuse it with the normal start-up, when the lights flash in sequence and then settle, or with the settings menu, where all the buttons flash after a long press.

On the DCF02 drip machine, the display and lights don't have an "all flashing" fault state in the manual. The ON/OFF and AUTO START lights flashing together with the red dot is just the descaling cycle running.

Settings Menus and Factory Reset (Espresso)

Useful if the lights are behaving oddly after someone changed a setting:

Machine switched itself off? That's auto shut-off. On the ECF02, press any button to wake it.

When to Call SMEG

Unplug it and call a SMEG service centre if:

• All lights flash and the espresso machine won't work
• Coffee drips from the filter holder rather than the spouts even with the holder fully turned home and clean. SMEG says a worn boiler outlet seal must be "replaced at an Authorised Service Centre"
• A drip machine has water in the base or on the control panel

In the US: SMEG's service partner ADCO, 1.888.763.4782. SMEG small appliances have a one-year warranty in the US and Canada; register within 30 days. Don't open the machine yourself.

FAQ

What does the red light mean on my SMEG coffee maker?

On the DCF02 drip filter coffee machine, the red dot under the clock is the descaling alert. Descale by holding ON/OFF and AUTO START for 5 seconds with water and SMEG descaler in the tank. The ECF01 and ECF02 manuals don't use red for their buttons: their descale light is orange. The red float in the drip tray just means the tray is full.

Why are all the lights flashing on my SMEG espresso machine?

If they flash in sequence after you switch on, it's heating up, so wait. If the machine won't work and all lights keep flashing, SMEG calls it a possible fault: unplug it and contact an authorised service centre.

Why are all the buttons orange on my SMEG ECF02?

It's in the Orange Menu, which makes long espressos. Press the programme-change key (23) to go back to the White Menu. Only the steam key flashing orange is a warning, and it means descale.

How do I reset my SMEG coffee machine?

On the ECF02, hold keys (21) and (23) together for at least 10 seconds. On the ECF01, open the settings menu (steam button, 10 seconds), turn the steam knob to steam and press the one-cup button. A factory reset restores the settings. For the descale warning, the manuals' answer is the descaling cycle.

How do I clear the descale light on my SMEG?

Run the descaling cycle to the end, including the rinse. On the DCF02 the red dot disappears when the display returns to the clock. On the ECF01 the orange light goes off at the end of the rinse. On the ECF02 the machine returns to ready.
