Two-chamber refrigerators Indesit with a system No Frost or drip defrosting require regular maintenance, even if the manufacturer claims “automatic” defrosting. Frost in the freezer more than 5 mm thick increases energy consumption by 20-30%, and improper defrosting can lead to damage to the compressor or electronics. This instruction is suitable for models Indesit C 138 NF, DF 4180 W, TIA 16 and other two-chamber refrigerators of the brand, including the lines Indesit ITF and Indesit BIAA.
Many users make a critical mistake: they pull the plug from the socket immediately after turning off the refrigerator. This may cause a voltage surge when switching on again, which is dangerous for the control board. Another common problem is using sharp objects to chip ice, which damages the evaporator and leaks freon. We will tell you how to avoid these and other mistakes, and also provide a checklist for safe defrosting.

1. Preparing a refrigerator for defrosting: what needs to be done in advance
Start with planning: defrosting a two-chamber refrigerator Indesit takes from 4 to 12 hours, depending on the thickness of the ice and the room temperature. If the layer of ice in the freezer exceeds 1 cm, take some time - forced acceleration of the process (for example, with a hairdryer) can damage the plastic parts.
First of all adjust the temperature on the control panel. In models with an electronic display (for example, Indesit BIAA 13), move the regulator to the 0° or OFFposition. In mechanical refrigerators (series Indesit C), turn the thermostat counterclockwise until it clicks. Do not turn off the refrigerator with the button Super Freeze —these are freezing modes, not shutdown!

-->
Pay special attention drainage system. In refrigerators Indesit with drip defrosting (models without No Frost), the drainage hole is located on the rear wall of the refrigerator compartment. If it is clogged, water will accumulate inside instead of draining into the pan. To clean, use a special brush (included) or a cotton swab dipped in a soap solution.
⚠️ Attention: If your refrigerator Indesit is equipped with a system Total No Frost (for example, model Indesit ITF 118 W), defrosting is required no more than once every 12-18 months. More frequent defrosting may indicate a malfunction of the fan or defrost sensor.
2. Step-by-step instructions: how to defrost an Indesit refrigerator without risk
The defrosting process consists of 5 stages. Follow them strictly in order to avoid breakdowns and reduce equipment downtime.
Stage 1: Shutdown and unloading (10-15 minutes)
1. Unplug the refrigerator without pulling out the plug —use the button on the panel (if available) or turn the thermostat to position OFF.
2. Get all the products. To keep them cold, put them in thermal bags with cold accumulators or wrap them in newspaper and place them in a cool place (for example, on a balcony in winter).
3. Remove all removable elements: shelves, containers, grilles. They can be washed separately in warm water with soda (2 tablespoons per 1 liter of water).
Stage 2: Melting ice (3-8 hours)
Close the refrigerator doors and leave them ajar 5-10 cm, placing a towel under them. This will speed up air circulation, but will prevent a sharp drop in temperature inside the chambers. In models with No Frost (for example, Indesit DF 5200 S) the ice melts faster - usually in 2-3 hours.
Critical important: Never use hot water, boiling water or heating devices (hair dryer, heater) to speed up the process. A sudden change in temperature can cause deformation of the plastic or damage to the seals.
Step 3: Removing water and cleaning (1-1.5 hours)
After the ice has melted, remove the water with a soft sponge or rag. Pay special attention to:
- 🔸 Drainage hole (clean it with a cotton swab)
- 🔸 Sealing rubber bands (wipe them with a 1:1 vinegar solution to disinfect)
- 🔸 The back wall of the refrigerator compartment (there condensation accumulates)
To wash the internal surfaces, use specialized products (for example, Indesit Clean) or a solution of baking soda (2 tablespoons per 1 liter of water). Avoid abrasive cleaners and hard brushes - they will scratch the plastic.
Step 4: Drying (1-2 hours)
Wipe all surfaces dry with paper towels or a clean rag. Leave the doors open for 1-2 hours to completely evaporate the moisture. In models with No Frost this stage is critical - residual moisture can freeze on the evaporator and form new ice.
Stage 5: Switching on and checking (30 minutes)
1. Connect the refrigerator to the network.
2. Set the thermostat to the middle position (usually 3-4 for the refrigerator compartment and -18° for the freezer).
3. Close the doors and wait until the refrigerator reaches temperature (about 30 minutes). Check that the compressor operates without any extraneous noise.
4. Load the products back, distributing them evenly for better air circulation.
3. Defrosting frequency: table for Indesit models
The manufacturer recommends defrosting refrigerators Indesit at least once every 6-12 months, but in practice the frequency depends on the model, operating conditions and type of defrosting system. Below is a table with approximate timing:
| System type | Indesit models | Recommended defrosting frequency | Signs of the need for unscheduled defrosting |
|---|---|---|---|
| Drip (manual) | C 138, C 168, TIA 16 | 1 time every 3-4 months | Ice in the freezer > 5 mm, increased compressor noise |
| No Frost (partial) | DF 4180, DF 5200, BIAA 13 | 1 time 6-8 months | Ice on the back wall of the refrigerator compartment, unpleasant odor |
| Total No Frost | ITF 118, ITF 120 | once every 12-18 months | Increased energy consumption, long compressor operating cycles |
| Low Frost | SB 167, SB 187 | once every 4-6 months | Ice on the freezer evaporator, uneven cooling |
If your refrigerator Indesit is equipped with a system Smart Frost (for example, model Indesit EWD 8140), monitor the defrost indicator on display. It turns yellow when maintenance is required.
⚠️ Attention: In refrigerators with No Frost ice may form due to a faulty defrost heater or sensor. If ice appears more than once every 3 months, diagnostics from a service center is required.

4. Typical mistakes and how to avoid them
Even experienced users make mistakes when defrosting, which shorten the life of the refrigerator. Here are the most common of them and ways to prevent them:
- 🚫 Using a knife or fork to chip the ice → Damages the evaporator and freon circuit tubes. Instead, use a plastic scraper or wooden spatula.
- 🚫 Defrosting at high room temperatures (> 25°C) → Increases the load on the compressor when turned on again. Optimal temperature for defrosting: 18-22°C.
- 🚫 Ignoring the drainage hole → Leads to stagnation of water and the appearance of mold. Clean the hole after each defrost.
- 🚫 Turning on the refrigerator immediately after washing → Wet surfaces may freeze, forming new ice. Always dry the chambers for at least 1 hour.
- 🚫 Using aggressive detergents → Corrodes plastic and seals. Use only specialized products or soda solution.
Another common mistake is incorrect positioning of products after defrosting. Do not place warm or hot food in the freezer - this will cause condensation and rapid ice build-up. The optimal temperature of products before freezing: no higher than +4°C.
What to do if the refrigerator does not turn on after defrosting?
If the refrigerator Indesit does not start after defrosting, check:
1. Connecting to the network (the machine on the control panel may have tripped).
2. Thermostat position (should be in position 1-5, not OFF).
3. Door seals - if they are damaged, the sensor may block the switch on.
If the problem persists, turn off the refrigerator for 10 minutes, then restart. If the compressor does not start, diagnostics of the control board or start relay is required.
5. Caring for seals and drainage system: extending the service life
Seals and drainage system are the most vulnerable elements of the refrigerator Indesit. Their improper maintenance leads to 70% of breakdowns associated with defrosting:
Seals
1. Cleaning: Wipe the elastic bands once a month with a vinegar solution (1:1) or a specialized product (for example, Indesit Door Seal CleanerThis prevents the growth of bacteria and loss of elasticity.
2. Grease: 2 times. Apply silicone grease to the seals every year (for example, WD-40 Specialist) This prevents cracking and ensures a tight fit.
3. Leak test: Close the door with a sheet of paper. If it falls out or is easily pulled out, the seal requires replacement.
Drainage system
1. Cleaning the hole: Use the brush from the kit or a cotton swab. In difficult cases, you can rinse the system with warm water using a syringe (without a needle!).
2. Disinfection: Once every 3 months, pour a soda solution into the drainage hole (1 teaspoon per 100 ml of water) to prevent mold.
3. Pallet check: It is located on the back wall of the refrigerator Drain the water and wash the tray with soap if dirt has accumulated there.
⚠️ Attention: If there is an unpleasant odor coming from the drainage hole of the refrigerator compartment Indesit this indicates a blockage in the drain tube. To clean, use a wire with a diameter of 2-3 mm, wrapped in a soft cloth.
6. How to speed up defrosting without harming the refrigerator
If there is no time for standard defrosting (6-12 hours), you can speed up the process without risking damage to the equipment. Here are safe ways:
- 💨 Fan: Point a table fan at the open freezer. Cold air will speed up the melting of ice. 30-40%.
- 💧 Bowls with water: Place containers with warm (not hot!) water in the chambers. Steam will speed up thawing. Change the water every 20-30 minutes.
- 🧊 Ice in bags: Place bags of ice from the freezer on the shelves. They will melt, speeding up the process.
- 🧼 Brine: Wipe the ice with a rag soaked in a salt solution (2 tablespoons per 1 liter of water). This will soften the ice and make it easier to remove.
Prohibited methods of acceleration:
- 🔥 Hot water or boiling water → Risk of plastic deformation.
- 🔥 Hairdryer or heater → Overheating of seals and electronics.
- 🔥 Metal scrapers → Damage to the evaporator.
In models with No Frost (for example, Indesit DF 5200 S) it is not recommended to accelerate defrosting - the system itself thaws the ice in 2-3 hours. Forced intervention can disrupt the operation of the fan.
7. Defrosting in emergency situations: what to do if...
Sometimes defrosting is required in unusual situations: when there is a power outage, a compressor breakdown or moving.
...the lights are turned off for a long time. period
If the refrigerator Indesit has been left without electricity for more than 12 hours:
- Do not turn it on immediately after applying voltage. Wait until the temperature in the room and inside the chambers equalizes (1-2 hours).
- Check the food for spoilage. in the freezer, the temperature has risen above -6°C, it is better to throw away the food.
- After turning on, set the thermostat to maximum cooling (
5-7) for 2 hours, then return to the normal value.
...the refrigerator stopped freezing
If the compressor is running, but the refrigerator is not cooling:
- Defrost it completely (see instructions above).
- Check if the drainage hole in the refrigerator compartment is clogged - a blockage may block air circulation.
- After turning on, listen to the the sound of the compressor. If it works without stopping, but does not cool, there may be a freon leak.
...you need to transport the refrigerator
Before transporting the refrigerator Indesit be sure to defrost and dry it Transportation rules:
- 🚛 Transport. the refrigerator only in a vertical position. If this is not possible, lay it on its side, but for no more than 30 minutes.
- 🚛 Secure the compressor with shipping bolts (if provided by the model).
- 🚛 After transportation, do not turn on the refrigerator for at least 4 hours - this time is necessary for the oil to settle in the compressor.
⚠️ Attention: If after transportation the refrigerator Indesit does not turn on or makes unusual sounds, do not try to repair it yourself. The compressor or freon circuit pipes may be damaged, which require professional intervention.
8. Frequently Asked Questions
Is it possible to defrost an Indesit refrigerator with No Frost?
Yes, but much less often - once every 12-18 months. The system No Frost prevents the formation of ice, but does not eliminate it completely. Defrosting is necessary to clean the drainage system and seals. data-i="222">s Indesit With Total No Frost (for example, ITF 120) ice can only appear if the fan or defrost heater is faulty.
How long does it take to defrost an Indesit refrigerator?
The time depends on the type of system and thickness frost:
- Drip system: 6-12 hours (with an ice layer of 1-2 cm).
- No Frost: 2-4 hours (ice melts faster due to ventilation).
- Low Frost: 4-6 hours.
You can speed up the process by using a fan or bowls of warm water (see section 6).
Why does the Indesit refrigerator make a lot of noise after defrosting?
This is normal in the first 1-2 hours after switching on. The compressor works in increased mode to reach the desired temperature. If the noise does not stop for more than 3 hours or is accompanied. knocking/vibration, check:
- Evenness of installation (the refrigerator should stand without distortions).
- Distance to the wall (minimum 5 cm for air circulation).
- Condition of the compressor shock absorbers (they can wear out over time).
How to wash the Indesit refrigerator after defrosting?
