Two-chamber refrigerators Indesit with system No Frost are advertised as not requiring defrosting - but this is not entirely true. Yes, ice forms in them 5-10 times slower than in drip models, but even the most advanced ventilation system does not protect against ice 100%. Especially if you actively use the freezer or often open the door. In this article we will look at how to properly defrost Indesit No Frost a two-chamber refrigerator, so as not to damage the equipment and save time.
The main problem of the owners of such refrigerators is ignorance of the nuances. Many people think that it is enough to simply turn off the power and wait, but this can lead to damage to the compressor or electronic unit. We will tell why you can’t defrost Indesit No Frost with the “Vacation” mode turned on in the networkhow to speed up the process without a hairdryer, and what to do if the refrigerator does not cool after defrosting. You will also find a table of defrosting time for different models and a preparation checklist.
The article is relevant for all two-chamber models Indesit s No Frostreleased after 2010, including popular series DF 4180 W, DF 5200 S, TLAA 10 and others. If your refrigerator is older, check the presence of the function Total No Frost in the instructions, since models before 2008 could use a hybrid type of defrosting.
Why do you need to defrost No Frost if it is “without defrosting”?
System No Frost (in translation - “without frost") works due to the constant circulation of cold air, which is evenly distributed throughout the chambers. Humidity condenses on a special evaporator, and not on the walls of the refrigerator, and periodically defrosts automatically. However, over time, even this system malfunctions:
- 🔹 Clogged drainage hole —if crumbs or grease get into it, the water does not drain into the pan, but freezes inside the chamber.
- 🔹 Fan failure —when stopped, air circulation is disrupted and ice forms on the back wall.
- 🔹 Excessive load on the freezer —if you store a lot of food without packaging, moisture from them settles on the walls.
- 🔹 Wear of the seal —if the door does not fit well, warm air gets inside, causing icing.
The manufacturer Indesit recommends doing it preventive defrosting once every 6-12 months - even if there is no visible ice. This helps:
- 🧼 Remove hidden ice in the air ducts that is not visible to the naked eye.
- 🔧 Check the operation of the drainage system and fan.
- 🦠 Eliminate bacteria and unpleasant odors that accumulate despite low temperatures.
⚠️ Attention: If your refrigerator Indesit is equipped with the functionFrost Free(and notTotal No Frost), you only need to defrost the freezer compartment - the refrigerator compartment is cleaned automatically. Check the markings on the sticker inside the chamber or in the passport.
Preparation for defrosting: what needs to be done in advance
Improper preparation is the main cause of breakdowns after defrosting. Never pull the plug from the socket immediately - this can lead to a voltage surge in the electronic unit. Here is a step-by-step plan:
- Adjust the temperature 12 hours before defrosting:
- Set in the refrigerator compartment
+4°C(instead of standard+5...+7°C). - In the freezer, raise the temperature to
-12°C(if it was lower).
This will reduce the load on the compressor when turned on after defrosting.
- Set in the refrigerator compartment
- Prepare the food:
- 🥩 Place meat and fish in airtight containers and wrap in a towel - this will slow down thawing.
- 🥛 Place dairy products and eggs in a cooler bag with cold batteries.
- 🍎 Remove fruits and vegetables in advance - they spoil faster when exposed to temperature changes temperatures.
- 🧽 Soft sponges and microfiber cloths (do not use hard brushes!).
- 🧴 Refrigerator cleaner (for example, Topperr 3101 or Sano Refrigerator Cleaner).
- 🔌 Extension cord with grounding (if the outlet is far from the sink).
- 📦 A tray or large towels for collecting water.

Step-by-step instructions: how to defrost Indesit No Frost two-chamber
The defrosting process takes from 4 to 12 hours depending on the model and amount of ice. Do not try to speed it up with a hairdryer or hot water - this can deform the plastic or damage it seals. Follow this algorithm:
Step 1: Disconnection and initial cleaning
1. Unplug the refrigerator. Do not press the on/off button - this may disrupt the electronic settings. block.
2. Open both doors wide open and secure them (for example, with a chair).
3. Remove all shelves, drawers and grids, wash them separately with warm water and soda (2 tablespoons per unit). 1 liter of water).
Step 2: Removing ice
1. If there is a thick layer of ice in the freezer (from 5 mm), carefully chip it off plastic with a scraper. Do not use a knife or metal objects —they will damage the coating.
2. Place bowls of warm (not hot!) water in the chambers - this will speed up the melting. Change the water every 30 minutes.
3. use rubber bulb with warm water, but do not pour directement water on electronic elements.
What to do if the ice does not melt for more than 6 hours?
If there is still ice in the freezer after 6 hours, check:
1. Drain hole —clean it with a cotton swab or a special brush (included with the refrigerator).
2. Ventilation grilles —they may be clogged with dust. Vacuum them at minimum power.
3. Seals —if they are deformed, the refrigerator is not airtight and the ice melts more slowly.
If the problem is not solved, the defrost heater may be faulty - in this case you will need repair.
Step 3: Washing and drying
1. After the ice has completely thawed, wash all surfaces with special. means or a solution of vinegar (1:1 with water). Avoid abrasive powders.
2. Pay special attention:
- 🔸 Rubber seals —wipe them with ammonia (1 teaspoon per glass of water) for disinfection.
- 🔸 Drain hole —rinse it with a warm syringe water.
- 🔸 Back wall —the most bacteria accumulate there.
3. Wipe all surfaces dry. Do not turn on the refrigerator when wet —this will lead to rapid re-icing.
4. Leave the doors open for 1-2 hours to dry completely.
Step 4: Turning on and checking
1. Insert all shelves and drawers into place.
2. Connect the refrigerator to the network. Do not immediately turn it on to the maximum mode — set the average temperature values (+5°C in the refrigerator compartment, -18°C in the freezer).
3. After 2-3 hours, check:
- 🔹 Are both chambers cooling evenly?
- 🔹 Is there any extraneous noise (knocking, creaking fan).
- 🔹 Is the display working (if any).
How long does defrosting take: table for different models
Defrosting time depends on:
- 🔹 Thickness of the ice layer.
- 🔹 Room temperatures (optimal
20-25°C). - 🔹 Refrigerator models (in new Indesit s
Total No Frostice melts faster).
| Refrigerator model | Ice thickness | Defrosting time (at 22°C in the room) | Features |
|---|---|---|---|
| Indesit DF 4180 W | Up to 3 mm | 3-4 hours | Fast defrosting thanks to improved ventilation |
| Indesit DF 5200 S | 3-7 mm | 5-7 hours | Sensitive to voltage changes - turn on through a stabilizer |
| Indesit TLAA 10 | 7-12 mm | 8-10 hours | Ice accumulates faster in the freezer due to narrow air ducts |
| Indesit BIAA 13 | Up to 5 mm | 4-5 hours | System Total No Frost —ice forms only when the drainage is clogged |
If your model has a function Fast Freezing ("Quick freezing"), before defrosting be sure to disable it otherwise the compressor will wear out when turned on.
Typical errors and how to find them avoid
Even experienced users sometimes make mistakes that lead to breakdowns. Here are the most common:
- 🚫 Using sharp objects to remove ice → scratches on plastic, freon leakage.
⚠️ Attention: If you damage the internal lining, the refrigerator may lose its seal. In this case, call a technician to check the pressure in the system. Do not turn it on; short circuit or firmware failure. data-i="206">Defrosting with the power on don't turn it on - Call a technician to check the pressure in the system.
- 🚫 Defrosting with power on → short circuit or firmware failure.
Some users think that if you leave the refrigerator in the
Holidaymode, it will defrost itself. In fact, this leads to icing of the evaporator and damage to the fan. - 🚫 Washing with aggressive detergents → corrosion of metal parts, unpleasant. smell.
Do not use bleach, Domestos or dishwashing detergents with abrasives. The best option is special sprays for refrigerators or soda solution.
- 🚫 Turning on a refrigerator with wet walls → instant icing and compressor overload.
If you are in a hurry, wipe the surfaces paper towels —they absorb moisture better than fabric.
Another common problem is incorrect temperature setting after defrostingMany people set it to maximum cold to “compensate” for defrosting. leads to:
- 🔹 Compressor overload (may burn out after 1-2 cycles).
- 🔹 Formation of condensation on products.
- 🔹 Increased electricity consumption by 20-30%.
How to care for No Frost in order to defrost less often
Following simple operating rules will reduce the frequency of defrosting from once every 6 months to once every 1.5-2 years:
- 📌 Control the loading of products:
Do not put hot foods in the refrigerator - this increases the humidity. The optimal temperature of the food when loading:
+18...+20°C. - 📌 Check the seals:
Wipe the rubber bands with silicone grease every 3 months (for example, WD-40 SpecialistThis will prevent them). cracking.
- 📌 Clean the drainage regularly:
Every 2 months, wash the hole in the refrigerator compartment with a solution of citric acid (1 teaspoon per glass of water).
- 📌 Do not block the ventilation grilles:
Do not place food close to the back wall - leave a gap of 3-5 cm for air circulation.
If your region has hard water, rinse the No Frost system with distilled water every six months.To do this:
- Disconnect refrigerator.
- Remove the back cover in the freezer (if you have access to the evaporator).
- Carefully rinse the evaporator with distilled water from a spray bottle.
- Dry for 24 hours.
What to do if the refrigerator does not work after defrosting
Sometimes after defrosting Indesit No Frost it refuses to turn on or does not work. incorrect. Here are possible causes and solutions:
| Problem | Possible cause | Solution |
|---|---|---|
| The refrigerator does not turn on | The compressor protection has tripped | Wait 10-15 minutes and turn it on again. If that doesn’t help, check the socket and power cord. |
Error is on F04 or F05 |
Temperature sensor malfunction | Turn off the refrigerator at 30 minutes. If the error remains, repair is needed. |
| Loud noise during operation | Ice is not removed from the ventilation system | Defreeze again, paying attention to the air ducts. |
| The upper chamber does not freeze | The air duct between the chambers is closed | Check if anything is blocking the air flow (for example, food packaging). |
If the refrigerator turns on, but does not coolcheck:
- Closeness of the door - place a sheet of paper between the seal and the body. If it falls out, the seal needs to be replaced.
- Fan operation - when the freezer door is open, you should hear a slight hum.
- Temperature setting - sometimes after defrosting the mode is lost (set again
+5°Ci-18°C).
⚠️ Attention: If after defrosting the refrigerator Indesit makes clicks or crackling in the first 2 hours, this is normal. But if the sounds are repeated. longer, turn off the equipment and call the technician.
FAQ: Frequently asked questions about defrosting Indesit No Frost
Is it possible to defrost an Indesit No Frost refrigerator without disconnecting the network?
No! Even if you switch it to the Holiday or Ecomode, complete defrosting is only possible if the power is completely turned off. Otherwise, the ice in the air ducts will not melt, and the electronic unit may fail due to temperature changes.
How much electricity does the Indesit No Frost refrigerator consume after defrosting?
In the first 24 hours after switching on, consumption may increase by 15-20% (up to 1.5-2 kW/day for class models A+This is normal - the compressor operates in increased mode to restore the temperature. After a day, consumption will return to normal. 0.8-1.2 kW/day.
What is the difference between Total No Frost and Frost Free defrosting in Indesit?
In models with Total No Frost (for example Indesit BIAA 13), both chambers are defrosted automatically, and manually cleaned only when heavily soiled. In Frost Free (for example Indesit ST 167), automatic defrosting only works in the refrigerator compartment, and the freezer needs to be defrosted manually every 6-12 months.
Is it possible to use a steam generator to speed up defrosting?
No! The steam generator creates too high a temperature and humidity, which can:
- 🔹 Deform plastic shelves.
- 🔹 Damage the electronic display (if any).
- 🔹 Lead to corrosion of metal parts.
The maximum that can be used is damp clothplaced on the shelves.
How often do you need to defrost Indesit No Frost if it is used by 1-2 people?
With a minimum load and rarely opening the door, it is enough to defrost the refrigerator every 1.5-2 years. However, even in this case, once every 6 months:
- 🔹 Check the drainage hole.
- 🔹 Wipe the seals.
- 🔹 Vacuum the rear grille (capacitor).
