Smeg sells coffee machines that look like part of the kitchen: the rounded ECF01 espresso machine, the DCF02 drip filter machine, the BCC01 and BCC02 bean-to-cup machines and the compact built-in units such as the CMS6451X. They are easy to love and, like any coffee machine, they stop in a few predictable ways. The coffee comes out slowly or not at all, the lights flash, a message asks for an infuser that you have already put back, the milk will not froth or water appears under the tray.
This page covers those faults using Smeg's own manuals: the ECF01 and DCF02 user manuals, the CMS6451X built-in manual and the BCC02 manual's troubleshooting excerpt. We label what comes from a retailer's blog, and we say where a manual gave no detail. Descaling has its own step-by-step page, so we link to it rather than repeat it: see our guide to descaling a Smeg machine.
When you book, a technician comes to your door, usually on the same day. He tells you what is wrong and what it costs before touching a part, and fixes it there if the machine allows. If it cannot be done at your address, we collect it.
The diagnostic visit is AED 100 plus 5% VAT. Repairs then run from AED 80 to AED 400 for most Smeg faults, depending on the part, and the price is fixed with you first.
Send a photo of the lights and the rating plate before the visit so the right parts travel with us.
Parts are genuine, and the price includes labour.
A one-month warranty covers the part and the work.
Your address is the first workshop. The real one is for what cannot be done there.

A drip filter machine is cheap to replace, and when a repair would not be worth it we say so.
The model code is on the base or back of the machine. The ECF01 manual lists one code per colour, so the full code on the plate tells us more than the colour does.

Smeg's service page tells owners of home appliances to contact the dedicated spare parts and service department in their country. It links to service pages for about twenty countries, none of them in the Middle East, and lists general authorised-assistance numbers under the Italian prefix. It gives no UAE or Middle East contact. We are an independent technician and not an authorised service partner of Smeg. We therefore name none.

The ECF01 manual's troubleshooting chapter is short and practical. We have paraphrased it and added what we do when the remedy does not work.

Smeg ECF01: lights, cleaning and care
Light or eventMeaning in the manual
Three button lights flash in sequence at power-onNormal start-up
One-cup and two-cup lights flashThe machine is warming. It is ready when they stop
Steam or descaler button orangeDescaling is due
Three buttons flash after holding a button for ten secondsProgramming mode
Frother light flashingThe machine is preparing steam
Red floater up in the drip trayThe tray is too full. Empty and clean it and the cup tray
Wipe the body with a soft damp cloth once the machine has cooled, and avoid steam jets.
Rinse the filter baskets under running water and clear the holes with a pin or brush.
Clean the frother straight after use. release a little steam, unscrew and slide off the frother, remove the rubber nozzle, wash in warm water, check the hole is clear and reassemble.
After every 200 coffees, flush about two cups of water through the group by pressing the coffee button with no coffee loaded.
Clean the water tank monthly with a damp cloth and mild detergent.
Avoid chlorine, ammonia or bleach on metal-finish parts, and abrasive or corrosive cleaners.
Steam, pods and the cup warmer have their own cautions: do not touch the cup warmer tray during use, and leave an inch of space at the sides and back and six inches above the machine.
Smeg ECF01: baskets and scoop
The ECF01 manual's parts list shows three filters: a soft pod filter, a one-cup ground coffee filter and a two-cup ground coffee filter. It also lists one measuring and tamping scoop. The manual's introduction says the machine makes coffee from ground coffee or soft pods.
Use the basket that matches the number of cups you are making.
The manual's troubleshooting table links pale crema and dark crema to the coffee and how it is pressed in, so check the dose and tamp before suspecting the machine.
A holder that will not latch is also a table entry. An overfilled or badly seated basket is the first thing to look at.
If the dose and tamp are right and the crema is still wrong, the group gasket, the basket or the pump needs a look. That is when a visit pays for itself.
A few lines written over a week make a diagnosis faster than any description given from memory. The Smeg manuals give us fixed messages and light patterns to record, so the log can be exact.
Write the message or light pattern word for word. On a CMS6451X that means text such as FILL TANK, INSERT INFUSER ASSEMBLY or GENERAL ALARM!. On a BCC02, name which alarm light is on and whether it is steady or flashing.
Note which drink you had ordered when the message appeared, milk or plain coffee.
Note what you did and whether the message cleared. tank refilled, grounds container emptied, infuser refitted, grind knob moved one click.
Note the days since the last descale and the last infuser clean, because the manuals tie several messages to those intervals.
Send the log, a photo of the plate and your area on WhatsApp. We arrive knowing which parts to bring.
Two Smeg messages come from the machine doing what the manual says. Knowing them saves a visit.
What you seeWhat is happeningSource

Machine stopped mid-cup on a BCC02The tank was out or low, or the door was openBCC02 manual excerpt
If the message stays after you have done what it asks, it is a fault and we should look at it.
The two bean-to-cup documents give the same direction for a grind that is too fine. The BCC02 excerpt says to turn the knob clockwise to loosen the coffee grinders when coffee dispenses slowly. The CMS6451X manual says that for GROUND TOO FINE ADJUST MILL you turn the grinding adjustment knob one click clockwise towards 7.
On the CMS6451X, turn the knob one click, then run hot water, as the manual says.
Change one click at a time and brew a cup before moving again.
If the message returns at a coarser setting, the cause is probably not the grind. Message us.
These are the two Smeg documents that gave a grind direction. For other bean-to-cup models, read your own manual before touching the knob.

If these steps do not cure the fault, the manual says to contact your local technical support centre.
The descaling icon is red when descaling is recommended and flashes until the cycle ends. Coffee can still be made while it is on.
A button LED flashing quickly means the machine is brewing.
A button LED flashing slowly with the KEEP WARM icon lit means Keep Warm mode, which runs the plate for 40 minutes.
One bean on the aroma icon is Delicate, two is Intense.
1
Open the menuHold the aroma button and the 4-cup button together for three seconds, then choose SE02.
2
Choose the levelThe default is HA02, medium. Use the lever to pick HA01 soft, HA02 medium or HA03 hard.
3
SavePress OK. The choice flashes for two seconds to confirm.
The machine decides when to ask for descaling from this setting, so a wrong hardness means the reminder comes too late or too early. Check the data plate.
Smeg's BCC machines show their state with icons rather than numbered codes. Smeg's own overview says an icon lights on the control panel when attention is needed and that a dedicated alarm tells you when to descale. The detailed meanings below come from the BCC02 manual's excerpt and from a retailer's blog, Barista Life, which attributes its table to Smeg's manual. The second column of the table is the blog's reading, not a quotation from Smeg.

Machine will not turn on. the manual's cause is a plug that is not fully connected.
Machine stops while dispensing. the tank is out or the water is below the minimum, or the side door was opened. Fit the tank properly or fill it, or close the door.
Coffee dispenses slowly. the grind is too fine. The manual says to turn the knob clockwise to loosen the grinders.
Clean the brewing group at least weekly, always empty the grounds container, and clean the steam wand after every use.
A light that stays on after you have done what it asks can point to a sensor, switch or board. That is a visit. For descaling see our guide.
The built-in CMS6451X shows words, not icons, and its manual has a full table. These are the messages and what the manual says.

The manual says the grounds container must be emptied whenever the drip tray is removed. It also tells you that if the unit is faulty you should not attempt repairs, but switch it off at the main switch, unplug it and contact customer services.
Cleaning the CMS6451X infuser and milk system
1
PrepareSwitch the machine off, open the service door and remove the drip tray and grounds container.
2
ReleasePress the two red release buttons inward while pulling the infuser out. Do not force it.
3
Soak and rinseSoak for about five minutes and rinse under the tap. The manual says not to use washing-up liquid, because it strips the lubricant from the piston and the infuser can seize.
4
RefitReinstall it and push until it clicks, and confirm both red buttons have snapped back out.
The manual asks for this at least once a month.
Clean the milk tubes inside the milk container each time you prepare milk.
Hold the CLEAN button on the lid for at least three seconds to run the internal cleaning cycle.
For a full clean, remove the spout, intake tube and frothed milk regulator, wash them in hot water with mild detergent and check for residue.
Put milk back in the fridge promptly. The manual says it should not sit out for more than 15 minutes.
Empty it before the red level indicator rises above the cup tray. The manual warns that overflow can seep into the unit and the cabinet.
Installing and powering a Smeg built-in
The CMS6451X manual gives installation rules that matter in Dubai kitchens, where a built-in coffee machine is normally fitted by the kitchen installer.
A qualified professional must install it, following local regulations.
It must sit in a column fixed firmly to the wall, with a gap at the bottom of the cabinet for ventilation.
Furniture touching the unit must withstand 65 degrees Celsius.
Do not install it where the room temperature can fall to 0 degrees or below, because water in the unit may freeze.
It may sit above a built-in oven only if the oven has a rear cooling fan and a maximum power of 3 kilowatts. Over a warming drawer, the drawer must draw 500 watts or less.
The cable must be long enough for the unit to be pulled out to refill beans, and the socket must stay accessible.
Use an earthed socket rated at 10 amps or more, with an omnipolar switch having at least 3 millimetres contact separation. No multiple sockets or extension cords.
Specification, CMS6451XFigure in the manual
Voltage220 to 240 volts, 50 or 60 hertz, maximum 10 amps
Absorbed power1,350 watts
Pump pressure15 bar
Water tank1.7 litres
Dubai's 230 volts at 50 hertz fits. The manual says the unit is for household use and not suitable for commercial use. A damaged plug or cable may be replaced only by customer services.
Water hardness and the filter on a Smeg
The CMS6451X manual says to set the water hardness as soon as possible. Dip the test strip in the water for a few seconds, wait about 30 seconds, count the red squares, then enter the menu, choose WATER HARDNESS and set the value to the count.
Remove the water softener filter before descaling the CMS6451X.
The BCC02 excerpt says the machine is factory set to hard water. The Smeg softener filter is optional and not supplied.
On the DCF02, set SE02 to HA01, HA02 or HA03 (see above).
We quote no hardness figure for Dubai because it varies by building. A test strip gives you a number to use.
Never put the machine, cord or plug in water, and unplug before cleaning.
Let the machine cool before cleaning it.
Use only original spare parts. Parts from other makers are not to be used.
Keep children under eight away, and do not let children play with it.
Do not use the DCF02 jug if it is damaged or the handle is loose, and do not use the appliance if its surface is cracked.
Fill the DCF02 tank before you put the plug in the socket.
The steam wand stays hot after steam delivery.
Do not run an espresso machine without water in the tank or without the tank in place.
Descaler contains acids that can irritate skin and eyes.
These are the manuals' points. Your own manual has the full list.

If a Smeg leaks or all its lights flash, switch it off, unplug it and let it cool. Empty the drip tray and the grounds container.
Photograph the lights or the message exactly as they show, because Smeg's machines report their state through lights and icons.
On a built-in machine, switch off at the isolator or breaker for that appliance rather than only at the front.
Do not remove the infuser or any part while a programme is running.

What is the cost of a Smeg coffee machine repair?
+
AED 100 plus VAT to diagnose, then mostly AED 80 to AED 400 for the repair, agreed before we start.
Is there a Smeg service centre in Dubai?
+
Smeg's service page lists service departments for about twenty countries and none in the Middle East. We are independent of Smeg and can usually attend the same day.
How do I descale my Smeg?
+
The steps differ by model. Our guide to descaling a Smeg machine covers the ECF01, DCF02 and bean-to-cup machines.
Why does my Smeg espresso machine drip around the filter holder?
+
The ECF01 manual lists a holder that is not attached properly or is dirty, a worn group gasket and clogged spout holes.
Why are all the lights on my Smeg flashing?
+
On the ECF01, the manual says to unplug the machine and contact an authorised service centre. On the BCC02, it is a hydraulic circuit error: make sure the tank has water and wait for it to reset.
What does INSERT INFUSER ASSEMBLY mean on my Smeg built-in?
+
The CMS6451X manual says the infuser was not put back after cleaning. Refit it until it clicks.
Can I wash the Smeg infuser with washing-up liquid?
+
No. The CMS6451X manual says detergent strips the lubricant from the piston and the infuser can seize.
What does GENERAL ALARM mean?
+
The CMS6451X manual says the inside is very dirty. Clean it thoroughly, and contact customer services if the message persists.
How do I set the water hardness on a Smeg DCF02?
+
Hold the aroma and 4-cup buttons for three seconds, choose SE02, pick HA01, HA02 or HA03 with the lever and press OK.
Why is my Smeg coffee dispensing slowly?
+
On the BCC02 the cause is a grind that is too fine, and on the ECF01 and DCF02 the manuals also list scale.
Does a Smeg work on Dubai's supply?
+
The CMS6451X is rated 220 to 240 volts at 50 or 60 hertz, which fits. Check the plate.
Is it worth repairing a Smeg?
+
A gasket, infuser, milk or pump fault usually is. For a board on an older built-in, or a basic drip machine, compare the quote with a new one.
