De’Longhi Numeric Error Codes
E1 Error Code
Important: De’Longhi uses E1 on different products for different faults, so E1 should never automatically be assigned one meaning across every De’Longhi coffee machine.
De’Longhi’s official support documents an E1 water-pressure-low error for specific De’Longhi products. This demonstrates why the machine’s exact model must be identified before diagnosing a numeric code.
What to do
Identify the exact De’Longhi model.
Check the model-specific manual or support information.
Check the water supply and tank where applicable.
If the code remains after the recommended checks, professional diagnosis may be required.
Do not treat E1 as a universal De’Longhi coffee-machine code.
The machine is detecting that the water tank is empty or does not contain enough water.
Check
Fill the tank with fresh water.
Make sure it is pushed fully into position.
Check that the tank is seated correctly.
If the message remains, the tank detection system may need inspection.
De’Longhi lists FILL TANK and related water-tank messages among the displayed messages on its automatic machines.
Insert tank / insert water tank
Check
Remove the tank.
Fill it if necessary.
Reinsert it firmly.
Make sure there is nothing preventing it from seating correctly.
If the machine continues showing the message with a correctly fitted tank, the tank detection system may require attention.
Water Circuit empty
A De’Longhi machine may display a water-circuit message when water has not yet filled the internal circuit.
The machine may instruct you to:
Fill circuit → hot water → press OK
If the message keeps returning
- Air in the water circuit
- Restricted water flow
- Incorrectly fitted water components
- A filter-related issue
- An internal water-system fault
Ground too fine – adjust mill
What to check
Adjust the grinder gradually.
Do not make a large adjustment at once.
Make another coffee after the adjustment.
Allow the machine to make several coffees before deciding whether another adjustment is necessary.
If coffee still does not flow
The problem may involve:
- Grinder blockage
- Brew-group restriction
- Coffee outlet blockage
- Excessively compacted grounds
- Water-flow problems
- Internal hydraulic problems
FILL BEANS CONTAINER
This message normally means the machine believes the bean container is empty.
FILL BEANS CONTAINER
This message normally means the machine believes the bean container is empty.
Check
Add fresh coffee beans.
Make sure the beans are actually reaching the grinder.
Check for beans bridging or sticking inside the hopper.
Do not overload the container.
If the machine says FILL BEANS CONTAINER even though beans are present, the bean-feed or detection system may require inspection.
De’Longhi lists this message on several automatic models.
EMPTY GROUNDS CONTAINER
The machine is asking you to empty the used coffee grounds.
Check
Remove the grounds container.
Empty it completely.
Clean away loose grounds around the container area.
Reinstall the container correctly.
If the message remains even after the container has been emptied and correctly reinstalled, the machine may not be detecting the container position correctly.
INSERT GROUNDS CONTAINER
The machine believes that the grounds container is missing or incorrectly positioned.
Check
Remove the container.
Check for coffee grounds obstructing the area.
Reinsert the container fully.
Make sure the drip tray and grounds container are correctly assembled.
If the message remains, the detection mechanism may require attention.
INSERT INFUSER ASSEMBLY
The infuser, also called the brew group on some machines, has not been correctly installed.
Check
Switch the machine off according to the instructions for your model.
Remove and inspect the infuser.
Check for obvious coffee residue or obstruction.
Reinstall it correctly.
Close the service door securely.
Do not force the brew group into position.
De’Longhi lists INSERT INFUSER ASSEMBLY as a model-specific displayed message.
ADD PRE-GROUND COFFEE
This message appears when the machine has been set to use pre-ground coffee but is waiting for the coffee to be added.
Check
Add the required quantity of ground coffee.
Use the correct scoop/measure for the machine.
Do not exceed the recommended amount.
Some De’Longhi models specifically instruct users to add no more than one measure of pre-ground coffee.
INSERT WATER SPOUT
The machine is not detecting the hot-water spout correctly.
Check
Remove the spout.
Check that it is clean.
Reinsert it firmly.
Try the hot-water function again.
If the machine still does not detect the spout, the connection or detection system may need inspection.
REPLACE FILTER
The machine is indicating that the water-softening filter needs attention.
Check
Replace the filter according to the machine’s instructions.
Make sure the new filter is installed correctly.
Reset or confirm the filter replacement if your model requires it.
Do not continue ignoring a filter reminder indefinitely, particularly in areas with harder water.
DESCALE
A DESCALE or DESCALING NEEDED message indicates that the machine's descaling cycle is due.De’Longhi's PrimaDonna Class support, for example, specifically displays DESCALING NEEDED, PRESS OK TO START.
What to do
Use the correct De’Longhi descaling procedure for your model.
Do not interrupt the process unless the machine’s instructions specifically tell you to do so.
If the descale warning returns unusually quickly, check the water-hardness setting and the machine’s maintenance requirements.
GENERAL ALARM
GENERAL ALARM is not a specific component diagnosis.
It means the machine has detected a condition that requires further attention.
De’Longhi lists GENERAL ALARM among the displayed messages on its automatic machines.
Before arranging repair
Safely check:
Water tank
Grounds container
Infuser/brew group
Bean container
Drip tray
Milk container
Water spout
Whether the machine needs cleaning or descaling
If the general alarm remains after the normal user checks, professional diagnosis is recommended.
Milk system error messages
- Milk system error messages
- turn dial to clean position
press ok to clean or turn milk dial
These messages can indicate that the milk container, frothing dial or cleaning procedure requires attention.
Check
Milk container position
Milk intake tube
Frothing dial
Milk outlet
CLEAN position
Milk residue around the system
A blocked or poorly maintained milk system can affect milk flow and frothing performance.
LESS COFFEE
Some De’Longhi machines display LESS COFFEE or recommend selecting a milder taste/reducing coffee.
This can occur when the selected coffee quantity or strength is too high for the machine’s current operating conditions. De’Longhi includes LESS COFFEE and SELECT A MILDER TASTE OR REDUCE COFFEE among model-specific messages.
Try
Reduce coffee strength.
Reduce the selected quantity.
Try another beverage setting.
Check whether the grinder is producing excessively fine grounds.
De’longhi la specialista warning lights
La Specialista machines use a different troubleshooting system from many automatic bean-to-cup machines.
De’Longhi’s official La Specialista support includes troubleshooting for:
- Flashing lights
- No espresso
- Coffee delivered too slowly
- Grinder problems
- Descaling
- Milk-frothing problems
- Other warning conditions.
All Lights Flash Briefly
If all the lights flash briefly when the machine is switched on, De’Longhi states that this can simply be the machine carrying out its self-diagnosis during startup.
Allow the machine to complete its startup process.
All Lights Keep Flashing
A continuous flashing-light condition can indicate a general alarm on certain La Specialista models. De’Longhi’s support directs users to customer service when this condition persists.
If the lights continue flashing after restarting the machine, professional diagnosis may be required.
DESCALE LIGHT FLASHING
A frequently flashing descale light does not necessarily mean the machine has suddenly developed a major mechanical fault.
De’Longhi notes that frequent descaling can be related to the machine’s water-hardness setting and limescale build-up.
Check
Whether the machine has actually been descaled.
Whether the water-hardness setting is correct.
Whether the descale procedure was completed correctly.
If the warning remains after a correctly completed cycle, further diagnosis may be required.
De’longhi grinder problems
A grinder-related problem may appear as:
- Ground too fine
- Coffee delivered too slowly
- No coffee delivery
- Grinder not operating
- Beans present but not feeding correctly
- Unusual grinder noise
For the GROUND TOO FINE message, De’Longhi specifically recommends adjusting the grinder gradually while it is operating.
Safe checks
Check the bean hopper.
Check whether beans are feeding.
Check the grinder setting.
Avoid forcing objects into the grinder.
Follow the model’s cleaning instructions.
A grinder that remains blocked or fails to operate may require professional service.
De’longhi coffee not coming out
If the machine makes a grinding or brewing sound but little or no coffee comes from the spout, possible causes can include:
- Grinder setting too fine
- Blocked coffee outlet
- Restricted brew group
- Insufficient water flow
- Coffee system contamination
- Internal hydraulic restriction
Start with the checks recommended for your exact model.
If the GROUND TOO FINE message appears, follow the grinder adjustment procedure first.
De’longhi machine not starting
If the machine does not switch on:
Check:
Power connection
Wall socket
Main power switch where fitted
Power cable
Correct startup procedure
If the machine has power but remains completely unresponsive, it may require electrical diagnosis.
Do not open the machine yourself if you are not qualified to work on mains-powered equipment.
De’longhi machine overheating
If the machine becomes unusually hot, switches itself off or refuses to operate normally, allow it to cool and follow the instructions for your exact model.
Repeated overheating should not simply be ignored.
Possible causes can involve:
- Internal temperature control
- Ventilation
- Pump or hydraulic problems
- Heating-system faults
- Electrical components
Professional diagnosis is recommended if the condition repeatedly returns.
What can you safely check yourself?
Before booking a repair, you can usually check:
- Water level
- Bean level
- Grounds container
- Drip tray
- Infuser/brew group position
- Water spout
- Milk container
- Grinder setting
- Coffee outlet
- Descaling requirement
- Water filter
- Power connection
Always follow the instructions for your exact De’Longhi model.
When does a de’longhi error need professional repair?
Arrange professional service when:
- A GENERAL ALARM remains after normal checks.
- The machine repeatedly loses water pressure.
- The grinder does not operate.
- The machine leaks internally.
- The machine repeatedly overheats.
- The machine switches off unexpectedly.
- The brew group cannot be installed or removed normally.
- The same error keeps returning after the recommended procedure.
- A flashing-light condition persists.
- The machine has an electrical fault.
- A flashing-light condition persists.
- The machine produces abnormal noises.
Do not continue operating a machine that has an obvious electrical, overheating or serious internal fault.
Frequently Asked Questions
No. De’Longhi troubleshooting is model-specific. Different machines can display different messages and warning systems.
It means the coffee is being ground too finely and the coffee is flowing too slowly or not at all. De’Longhi recommends adjusting the grinder gradually on affected models.
It indicates that the machine has detected a condition requiring attention. The exact cause depends on the model and circumstances.
The machine may not be detecting the tank correctly. Remove and reseat the tank and check that it is correctly positioned.
The beans may not be feeding into the grinder correctly, or the machine may not be detecting them correctly.
If they flash briefly during startup, this can be part of the machine’s self-diagnosis. If they continue flashing, some La Specialista models treat this as a general alarm requiring further attention.
Not necessarily. Because De’Longhi uses model-specific messages and troubleshooting, it is usually more useful to keep the main De’Longhi Error Codes & Messages hub comprehensive and create separate model pages only where there is enough distinct search intent and technical information.
