Maintaining your De’Longhi coffee machine includes regularly replacing the water filter for optimal taste. If you’re wondering exactly how to change filter on delonghi coffee machine, you’ve come to the right place. This guide will walk you through the entire process, making it simple and straightforward. A clean filter ensures your coffee tastes its best and helps protect your machine from scale build-up.
Changing the filter is a quick task that makes a big difference. We’ll cover everything from identifying your filter type to the step-by-step replacement. You’ll also learn how to prepare a new filter and reset the indicator light. Let’s get started so you can enjoy perfect coffee again.
How To Change Filter On Delonghi Coffee Machine
The core process for changing the filter is similar across most De’Longhi models that use the official De’Longhi water filter cartridge. These white, cylindrical filters are common in many espresso and drip coffee machines. The key steps involve removing the old cartridge, preparing the new one, and inserting it correctly. Always consult your specific user manual for model-specific details, as the location of the filter holder can vary.
Identifying Your DeLonghi Filter Type
Before you begin, it’s crucial to identify which filter system your machine uses. De’Longhi primarily uses two types: the replaceable cartridge filter and the integrated descaling system. The cartridge filter is the one you will physically remove and replace. The integrated system often uses a filter inside the water tank or a built-in technology that manages water hardness; for these, you typically add a descaling solution rather than change a physical part.
Look for a white cylindrical cartridge either inside the water tank or attached to the tank lid. This is the DLS CFF-1 or a similar replacement filter. If your machine has a “Filter” or “Water Filter” indicator light on the control panel, it uses this replaceable cartridge system. If you’re unsure, checking the model number on the bottom of your machine and referencing the manual is the best course of action.
Tools And Supplies You Will Need
You don’t need many tools for this job. Gathering everything beforehand makes the process smoother. Here is what you’ll need:
- A new, genuine De’Longhi replacement water filter (model DLS CFF-1 or the specific type for your machine).
- A clean bowl or large cup filled with fresh, cold water.
- A clock or timer.
- A clean cloth or paper towel.
- Your machine’s user manual for reference (optional but helpful).
Step-by-Step Replacement Guide
Follow these numbered steps carefully to change your filter correctly. Rushing can lead to improper installation or forgetting to reset the indicator.
Step 1: Prepare the New Filter Cartridge
New filters must be activated and rinsed before use. Do not skip this step. Remove the new filter from its packaging. Submerge it completely in a bowl of cold water. Gently squeeze it several times to release any air bubbles. Let it soak for the time specified on the packaging, usually about 15 minutes. After soaking, remove the filter and rinse it under cold running water for about 30 seconds. This prepares the activated carbon inside for optimal performance.
Step 2: Remove the Old Water Filter
Ensure your coffee machine is turned off and unplugged for safety. Remove the water tank from the machine. Locate the old filter cartridge. It is usually attached to a holder on the underside of the tank lid or sits in a compartment inside the tank itself. To remove it, simply twist the cartridge counter-clockwise (left) about a quarter turn. It should then release and you can pull it straight down and out. Discard the old filter.
Step 3: Insert the New Filter Cartridge
Take your prepared new filter. Align it with the holder in the water tank or lid. Insert it and twist it clockwise (right) until it locks securely into place. You should feel it click or stop turning. Do not force it, as this could damage the plastic threads. A snug fit is sufficient. If your filter sits in a compartment, it may just push in without twisting—check your manual for the correct method.
Step 4: Reassemble and Refill the Water Tank
If you removed the tank lid, reattach it securely. Place the water tank back into the coffee machine, ensuring it is seated properly. Fill the tank with fresh, cold water up to the maximum line. It’s normal for the water to appear slightly dark or have small black particles at first; this is just residual carbon from the new filter and is harmless. You may want to run a few cycles of plain water through the machine (without coffee) to flush the system before brewing your first cup.
Step 5: Reset the Filter Indicator Light
Many De’Longhi machines have an alert light that reminds you to change the filter. After replacing it, you need to reset this timer. The method varies by model. A common procedure is to press and hold the “Filter” or “Water Filter” button for 5-10 seconds until the light stops flashing or turns off. On some models, you might need to press a combination of buttons. Refer to your manual for the exact reset sequence for your machine. This step is important so the machine accurately tracks the next filter change interval.
How Often To Change Your DeLonghi Filter
De’Longhi recommends changing the water filter cartridge every two months, or after approximately 60 tank refills. However, this can depend on your usage and water hardness. If you use your machine multiple times a day, you may need to change it more frequently. If you have very hard water, sticking to the two-month schedule is wise to prevent scale. The filter indicator light on your machine is the best guide, as it calculates usage automatically.
Troubleshooting Common Filter Issues
Sometimes, things don’t go perfectly smoothly. Here are solutions to common problems you might encounter.
Water Tastes Strange After Filter Change
If your first few cups taste odd or have particles, you likely didn’t rinse the new filter long enough. Run three to four tankfuls of plain water through the machine’s brewing cycle (without coffee) to fully flush the system. This should clear any remaining carbon dust. Also, ensure you used cold water to prepare the filter, as hot water can damage the carbon media.
Filter Indicator Light Won’t Reset
If the light remains on after you’ve tried the reset procedure, double-check that the new filter is installed correctly and fully locked in. The machine may have a sensor that detects proper installation. Unplug the machine for 60 seconds, then plug it back in and try the reset sequence again. If it persists, consult your manual for a hard reset option.
Water Is Leaking From The Tank Area
Leakage is often caused by an improperly seated filter or tank. Turn off the machine and remove the tank. Check that the filter is twisted all the way into the locked position. Also, inspect the rubber seal on the filter holder for any damage or debris. Ensure the water tank itself is correctly placed and clicked into its base. A cracked tank can also cause leaks.
Benefits Of Regular Filter Changes
Changing your filter isn’t just a maintenance chore; it provides real benefits for your coffee and your machine. A fresh filter reduces chlorine, limestone, and other impurities from your water, leading to a purer, better-tasting coffee where you can truly taste the beans’ flavor notes. It significantly reduces scale build-up inside the machine’s internal tubing and heating element, which can cause costly repairs and decrease the machine’s lifespan. It also helps maintain optimal brewing pressure and temperature for a consistent cup every time.
FAQs About DeLonghi Coffee Machine Filters
Can I use a generic water filter instead of a De’Longhi brand one?
It is strongly recommended to use genuine De’Longhi DLS CFF-1 filters. Generic filters may not fit correctly, could leak, and might not meet the same performance standards for filtration and flow rate, potentially affecting your machine’s operation and warranty.
What if my machine doesn’t have a filter indicator light?
Many older or simpler models do not have an indicator. For these, you should manually track the time or number of tank refills. Setting a reminder on your calendar for every two months is an effective way to remember to change the filter on schedule.
Do I still need to descale if I use a water filter?
Yes, you still need to descale your machine periodically, even with regular filter changes. The water filter reduces scale formation but does not eliminate minerals entirely. Follow your machine’s descaling instructions, typically every 3-6 months depending on water hardness.
Where can I buy replacement De’Longhi water filters?
You can purchase them from appliance retailers, kitchen specialty stores, or online marketplaces like Amazon. Always buy from a reputable seller to ensure you get an authentic, new filter and not an expired or counterfeit one.
How do I know when the filter is truly exhausted?
Aside from the indicator light, signs include a noticeable change in your coffee’s taste, a slower brewing time, or visible scale starting to appear in the tank or on the heating element. If in doubt, change it—filters are inexpensive compared to machine repairs.
Changing the water filter in your De’Longhi coffee machine is one of the simplest yet most impactful forms of maintenance you can perform. By following this guide, you ensure your machine runs efficiently, your coffee tastes excellent, and you avoid preventable problems down the line. Remember to mark your calendar for the next change in two months, and always keep a spare filter on hand so you’re never without great-tasting coffee.
