Disassembling the Hotpoint-Ariston refrigerator: detailed instructions with photos and diagrams

Disassembling a refrigerator Hotpoint-Ariston is a task that owners face when they need to repair, clean or replace parts. The brand, part of the group Indesit Company, is known for its reliability, but even the highest quality models require maintenance. In this article you will find step-by-step instructions taking into account the features of different cooling systems, as well as list tools and critical nuancesthat are not written about in standard manuals.

It is important to understand that disassembling a refrigerator is not just about unscrewing the screws. It is important procedureto be careful when working with freon and electrical equipment, as well as knowledge of the design differences of your model. For example, in units with a system No Frost the algorithm for dismantling the rear panel differs from drip refrigerators. If you have never dealt with equipment of this level, it is better to entrust the work to a professional. But if you decide to act on your own, follow our recommendations.

⚠️ Attention: Hotpoint-Ariston regularly updates the design of refrigerators. If your model was released after 2023, check the location of the fasteners and connectors with the official documentation - they may differ from those described in the article.

1. Preparing for disassembly: tools and safety precautions

Before you begin disassembling, make sure that the refrigerator completely disconnected from the network is defrosted. Even if you plan to work only on mechanical parts, there is still a risk of short circuiting when exposed to moisture. Remove all products, shelves and containers - they will interfere with access to internal components.

Minimum set of tools for disassembly:

• 🔧 Phillips and flathead screwdrivers (preferably with a magnetic tip)
• 🔨 Set of socket wrenches (sizes 8, 10, 12 mm)
• 📏 Plastic spatula or mediator for dismantling panels
• 🔌 Multimeter for checking circuits (if you plan to diagnose electronics)
• 🧲 Magnet for collecting small screws and nuts

If your model is equipped with a system No Frost, additionally prepare a vacuum cleaner with a narrow nozzle —it will help remove accumulated dust from the air ducts. For refrigerators with a drip system, you may need silicone grease for sealing rubber bands.

⚠️ Attention: Do not use metal objects to remove plastic panels - this may lead to cracks. If the mount is “stuck”, wet it WD-40 and wait 5-10 minutes.

2. Dismantling internal elements: shelves, doors, seals

Start by removing all removable parts inside the chamber. In models Hotpoint-Ariston shelves are usually mounted on plastic guides or metal brackets. To remove a glass shelf:

1. Lift it up until it stops.
2. Tilt it towards you at an angle of 30–45°.
3. Carefully pull it out of the grooves.

Door shelves are dismantled by sliding them up or down (depending on the model). The sealing rubber is attached either to screws (old models) or to clips (new). To remove it:

• 🔍 Find the joint of the elastic in the upper corner of the door.
• 🖐️ Pry it with a plastic spatula and pull it towards you.
• 🔄 Repeat the action around the entire perimeter.

If the seal is glued, use hair dryer to heat the adhesive layer - this will make dismantling easier. In Hotpoint-Ariston models 2022–2026, seals are often attached to double-sided tape, which requires replacement after removal.

3. Removing the rear panel: access to the compressor and condenser

The rear panel of the refrigerator Hotpoint-Ariston is attached to 4-6 screws (depending on the model). Units with No Frost may additionally have a plastic cover covering the fan. Dismantling algorithm:

1. Unscrew all visible screws around the perimeter.
2. If the panel cannot be removed, check for hidden fasteners under stickers or plugs.
3. Remove the panel by pulling it towards you and up (in some models there are latches).

After removing the panel you will have access to:

• 🔧 Compressor (black cylindrical block with tubes).
• 🌀 Condenser (grid of tubes, usually in the lower part).
• ⚙️ Start relay (small box on the compressor).
• 💨 Fan (only in models with No Frost).

Pay attention to labeling of tubes — in refrigerators Hotpoint-Ariston often colored marks are used:

• 🔴 Red - high pressure inlet.
• 🔵 Blue - low pressure outlet.
• 🟢 Green - capillary tube.

Do not confuse them when reassembling!

What to do if the back panel cannot be removed?

If the panel is "jammed", check:

- The presence of additional screws under the sticker with the serial number.

- Plastic latches on the sides (they need to be carefully bent with a screwdriver).

- In models with No Frost, you may need to first remove the top cover, as it blocks access to the fasteners.

4. Disassembling the No Frost system: fan, heating element, sensors

Refrigerators Hotpoint-Ariston with the system No Frost have a more complex design due to the presence of a fan and evaporator. To get to these elements:

1. Remove the back panel of the freezer (usually attached to 3-4 screws).
2. Disconnect the fan power connector (white plastic connector).
3. Unscrew the fan fasteners and remove it.
4. Located behind the fan defrosting heating element —it can be dismantled after unscrewing two nuts.

Pay special attention defrost sensor —it is attached to the evaporator and often breaks if not handled carefully handling. In models Hotpoint-Ariston this sensor is usually black with two wires (red and white).

In Hotpoint-Ariston refrigerators with the Full No Frost system (HF series models), the evaporator is hidden behind a foam panel. To dismantle it, you will need to cut the foam with a knife, and after repair, restore the thermal insulation with polyurethane foam.

5. Working with the compressor and freon circuit

The compressor is the “heart” of the refrigerator, and its disassembly requires special care. In models Hotpoint-Ariston compressors are usually installed Embraco or Secop. For dismantling:

1. Disconnect the start relay (unscrew the 2 screws and disconnect the connector).
2. Have a bite with a pipe cutter copper tubes at a distance of 2-3 cm from the compressor.
3. Unscrew the 4 bolts securing the compressor to the frame.
4. Carefully remove the compressor without bending the tubes.

If you plan replacement compressor, consider the following nuances:

• 🔄 The new compressor must be of the same type and power (check the markings on the old one).
• 🔧 When soldering tubes, use silver solder and flux for copper.
• ⚠️ After replacement, be sure vacuum the system (at least 30 minutes) before refilling freon.

To refill freon you will need:

• 🛠️ Manometric manifold.
• 🧊 Freon cylinder (usually R134a or R600a for new models).
• 🔥 Gas burner for soldering.

⚠️ Attention: Working with freon requires certification! Incorrect refueling can lead to explosion or poisoning. If you do not have experience, contact a specialist.

6. Diagnostics and replacement of electronic components

Electronic boards in refrigerators Hotpoint-Ariston are located either on the back panel or under the top cover. The main elements that may require replacement:

• 📱 Main control board (models with a display).
• 🔌 Power supply (in refrigerators with inverter compressors).
• 🌡️ Temperature sensors (usually 2-3 pieces: in the freezer, fridge compartment and on the evaporator).

To diagnose the board:

1. Disconnect all connectors and remove the board from the mounts.
2. Visually inspect for blackened elementsswept capacitors or cracks.
3. Test the power circuit with a multimeter (the resistance between the contacts should be in the range of 20–200 kOhm).

If the board is faulty, it can be:

• 🔧 Repair (replace burnt elements, if any soldering skills).
• 🔄 Buy a new one (specify the exact model of the refrigerator when ordering).
• 📞 Send for repairs (many service centers restore boards for 30–50% of the cost new).

Temperature sensors are checked by measuring resistance under different conditions:

• 🌡️ At room temperature: 4–6 kOhm.
• ❄️ At 0°C: 10–12 kOhm.
• ❄️❄️ At -18°C: 20–30 kOhm.

If the readings do not correspond to the norm, the sensor must be replaced.

7. Assembling the refrigerator after disassembling: key points

Assembly should take place in in the reverse order, but there are several critical points that are often missed:

1. The sealing rubber band should be installed without distortions. You can check the tightness using sheet of paper - if it is easily pulled out when the door is closed, the seal needs to be adjusted.
2. Freon circuit tubes should be secured with clips to avoid vibration and friction against the body.
3. Electrical connectors connect only after complete assembly of the mechanical parts so as not to damage the wires.

After assembly:

• 🔌 Connect the refrigerator to the network and let it stand for 2-3 hours without food.
• 🌡️ Check the temperature in the chambers after 6-8 hours (should correspond to the set one).
• 🔊 Listen to the operation of the compressor - it should not there may be extraneous noise or vibrations.

If the refrigerator does not turn on or does not work correctly:

• 🔍 Check the connections of all connectors.
• 📋 Make sure that there are no "extra" screws or parts left.
• 📞 Contact to the technician if the problem persists.

8. Common mistakes during disassembly and how to avoid them

Even experienced craftsmen sometimes make mistakes that lead to breakdowns. Here are the most common:

• 🔧 Tightening the screws — leads to cracks in plastic panels. Use a torque screwdriver with a force of no more than 1.5 Nm.
• ⚡ Short circuit when checking electronics. Always disconnect capacitors before testing the circuits.
• ❄️ Moisture getting into the system when replacing the compressor. Evacuation is a must!
• 🔄 Incorrect assembly No Frost —if you forget to connect the defrost sensor, the system will freeze.

To avoid problems:

• 📸 Take photographs of each disassembly step —this will help during assembly.
• 📝 Keep a record of the location of the screws (they may vary in length).
• 🛠️ Use specialized tools (for example, ratchet socket wrenches for hard-to-reach places).

Hotpoint-Ariston MB and MF series refrigerators often have problems with evaporator icing due to a faulty defrost timer. If, after disassembling, ice appears again within a week, check this element first.

FAQ: Answers to frequently asked questions

Is it possible to disassemble Hotpoint-Ariston refrigerator without experience?

Theoretically yes, but the risk of damaging parts or electronics is very high. Start with simple tasks (cleaning, replacing the seal), and for complex work (compressor, freon) it is better to invite a specialist.

How to understand that the compressor is faulty?

Signs of a faulty compressor:

• The refrigerator does not cool, but there is light inside lights up.
• The compressor hums, but does not start (protection is activated).
• Traces of oil or rust are visible on the compressor housing.

Accurate diagnostics can only be carried out with a multimeter (checking the windings).

What what to do if after disassembling the refrigerator does not turn on?

Check:

• Connection of all connectors (especially the control board).
• Integrity of the fuse (usually located on the compressor).
• Correct connection of temperature sensors.

If everything is in order, but the refrigerator does not work, the electronic unit may break down.

How often should you disassemble the refrigerator for cleaning?

Recommended frequency:

• Drip models: once every 1-2 years (cleaning the drainage and back panel).
• No Frost: once every 3-4 years (cleaning the fan and evaporator).

If the refrigerator is used in conditions of high humidity (for example, in a kitchen with poor ventilation), cleaning should be done more often.

Is it possible to replace freon yourself?

Technically it is possible, but for this you need:

• Certificate for working with freon (mandatory in some countries).
• Special equipment (gauge manifold, vacuum pump).
• Knowledge of types of freon (for example, R600a explosive!).

Without experience, it is better not to take risks - a mistake can lead to a gas leak or compressor failure.
