You'll learn what tools you'll need, how to avoid common mistakes, and when you should really turn to professionals. And for those who are planning not only cleaning, but also repairs, we have prepared a table of spare parts compatibility and tips for replacing them.

Preparing for Disassembly: Tools and Safety Precautions

Before you begin disassembling, make sure that the coffee machine has completely cooled down - this will prevent burns and deformation of the plastic parts. Disconnect the device from the network and drain the remaining water from the system through the drain valve (usually located at the rear). If you plan to clean, prepare a container and a rag to catch the liquid - residual coffee oil or water may spill during the process.

Minimum set of tools for disassembly Magnifica S:

• 🔧 Phillips screwdriver (size PH1 or PH2) - for most housing screws.
• 🔧 Flat head screwdriver or a plastic pick - to carefully separate the latches.
• 🔧 8 mm socket wrench or socket — for metal frame screws (if deep disassembly is required).
• 🧴 Silicone grease (for example, DeLonghi CL100) - for treating seals after cleaning.
• 📸 Smartphone - to photograph the disassembly process (this will greatly simplify assembly!).

If you are disassembling a car for repairs, you may additionally need:

• 🔍 Multimeter — to check power circuits and heating elements.
• 🧲 Magnetic screwdriver - to avoid losing small screws in hard-to-reach places.
• 🧽 Ultrasonic bath — for cleaning small parts (for example, the cappuccino nozzle).

⚠️ Attention: If your Magnifica S It is under warranty; disassembling it yourself will void it. Check the terms in the warranty card or on the website DeLonghi before starting work.

Removing the Top Cover and Control Panel

Start with removal top decorative cover. It is secured with two latches at the front and one screw at the back (under the rubber foot). Carefully pry the cover off with a flat-head screwdriver from the front - you will hear a characteristic click. Then slide it back and remove it. Under the cover you will see:

• 🔌 Power supply (left).
• ☕ Grain hopper (center).
• 💧 Water supply tubes (right).

Next, unscrew the two screws securing control panel (they are located under the top cover, on the sides of the display). Carefully disconnect the button and display cables - to do this, pull the plastic connectors up. Do not pull on the wires to avoid damaging the contacts! If the connectors are tight, use a flathead screwdriver to pry them up.

After removing the panel you will have access to:

• 🔋 Control board (with microcircuit and relay).
• 🔄 Pump motor (black cylinder with wires).
• 🚰 Water supply valve (small white block with tubes).

⚠️ Attention: If you notice traces of oxidation or burnt tracks on the control board, do not turn on the machine until they are repaired. This may cause a short circuit.

Removing the brew group

Brewing unit - the heart of the coffee machine, and its disassembly requires special care. B Magnifica S it is located in the front and is secured with two screws (front) and one latch (rear). Before extraction:

1. Make sure there is no coffee tablet in the unit.
2. Open the door and remove cappuccino maker (turn counterclockwise).
3. Disconnect milk supply tube (if it is connected).

Remove the two screws from the front (they may be hidden under decorative caps). Then carefully pull the block towards you - it should come out of the grooves. If the unit is “jammed,” do not force it: check to see if you forgot to unscrew the screws or disconnect the tubes.

After removal, inspect the block for:

• 🔍 Wear of silicone seals (they should be elastic, without cracks).
• ☕ Coffee stain on the piston and filter.
• 🔧 Play in moving parts (may indicate bushing wear).

For deep cleaning, disassemble the unit:

1. Remove the top cover of the unit (2 latches).
2. Remove the piston and spring.
3. Clean the filter and sprayer from scale (use a special product, for example, DeLonghi EcoDecalk).

What happens if you don't clean the brewing unit?

The accumulation of coffee oil and scale leads to:

- Deterioration of the taste of coffee (bitterness, sourness).

- Slowing down the brewing process (water flows worse).

- Piston breakage due to increased friction.

- Leaks due to destruction of seals.

Recommended cleaning frequency: every 200-300 cups or once every 3 months.

Disassembling the water supply system and heating element

If the problem lies in leaks or insufficient water heating, you will have to get to the heating element and pump. To do this:

1. Remove back cover (4 screws).
2. Disconnect water supply tubes from the tank (they are secured with plastic clamps).
3. Unscrew the screws securing metal frame (usually 3-4 pieces).

Under the frame you will see:

• 🔥 heating element (tubular heater with temperature sensor).
• 💦 pump (black cylinder with wires).
• 🔄 Three way valve (responsible for releasing pressure).

To check the heating element, use a multimeter:

1. Switch the device to resistance measurement mode (200 Ohm).
2. Connect the probes to the contacts of the heating element.
3. Normal resistance: 25-40 Ohm. If the readings 0 or ∞ — The heating element is faulty.

Frequent problems with this system:

Symptom	Probable Cause	Solution
The machine does not heat the water	The heating element or temperature sensor is faulty	Replacing the heating element (article: C000760587)
Weak water pressure	Pump or tubes clogged	Flushing the system DeLonghi CL100
Leak under the car	Crack in the tube or worn seal	Replacing tubes (set C000999999)
The machine does not turn on	Problems with the control board	Diagnostics with a multimeter or board replacement

⚠️ Attention: When replacing a heating element or pump, use original spare parts. Cheap analogues may not withstand pressure of 15 bar and lead to serious damage.

Cleaning and lubrication of moving parts

After disassembly, be sure to clean all parts from coffee oil and scale. To do this:

• 🧼 Plastic parts (body, drip tray) wash in warm water with a mild detergent.
• ☕ Metal parts (piston, filter) soak in descaling solution (e.g. Durgol Swiss Espresso) for 30 minutes.
• 🧴 Silicone seals Wipe with a damp cloth without harsh chemicals.

To lubricate moving parts (such as the brew unit guides), use food grade silicone grease. Apply it in a thin layer, avoiding contact with the seals. Never use WD-40 or other technical lubricants - they ruin the plastic and leave an aftertaste in the coffee!

Pay special attention to:

• 🔄 Drive gears (if they squeak).
• 🚪 Door hinges (for smooth opening).
• ☕ Cappuccinatore sprayer (clean out dried milk with a needle).

Assembling a coffee machine: procedure and common mistakes

Assembly DeLonghi Magnifica S should go in reverse order, but there are several critical points:

1. Make sure everything seals installed in their places (their distortions will lead to leaks).
2. Check your connection tubes - they should fit tightly, without kinks.
3. Do not over-tighten the screws as this may cause cracks in the plastic housing.

Common errors during assembly:

• ❌ Mixed up connectors on the control board → the machine does not turn on.
• ❌ Incorrectly installed brewing unit → coffee pours past the cup.
• ❌ Rags or tools forgotten inside → breakdown when turned on.

After assembly, perform a test run:

1. Fill the tank with water and turn on the machine.
2. Start the rinse program (Menu → Cleaning → Rinse).
3. Prepare a test cup of coffee without beans (water only) to check for leaks.
