Modern refrigerators Indesit with a system No Frost relieve owners from the need for regular manual defrosting, but this does not mean that the equipment does not need to be washed. Over time, odors accumulate inside the chambers, and a coat of ice can form in technical niches hidden from view, which reduces the efficiency of the compressor. Many users mistakenly believe that the absence of ice on the walls means the entire system is perfectly clean, but this is not the case.
Dirt and bacteria often accumulate in hard-to-reach places where the main air flow does not reach during normal use. Regular maintenance will extend the life of the unit and maintain food freshness. In this article we will look in detail at how to properly and safely completely clean your refrigerator, paying special attention to the elements of the system No Frost.
Preparation for the defrosting and washing process
Before starting any work, you must completely empty the refrigerator and freezer compartments of food. It is best to plan cleaning in advance so that you have time to use or recycle supplies before turning off the appliance. All shelves, drawers and containers should be removed and washed separately with warm water and a mild detergent.
Be sure to unplug the refrigerator. For models Indesit this is critically important, since any manipulation of internal live components may result in electric shock or damage to the electronics. After turning off, leave the doors open for at least 24 hours to evaporate moisture and melt any possible ice in the evaporator.
⚠️ Attention: Do not use sharp objects, knives or scrapers to chip away ice inside the chambers. Damage to the plastic walls or evaporator tubes will lead to refrigerant leakage and expensive repairs, which are often not economically feasible.
While the natural defrosting process is in progress, cleaning agents can be prepared. For the inner surface of the chambers, a baking soda solution or a special refrigerator cleaner is best suited. Aggressive chemicals such as acetone or gasoline can damage plastic and rubber seals.
Dismantling internal elements and panels
After the refrigerator has defrosted, you need to gain access to the hidden components of the system No Frost. In the freezer, you usually need to remove the top cover, which hides the fan and evaporator. In the refrigerator compartment, it is often necessary to remove the rear plastic panel.
Fasteners can be hidden under decorative plugs or located deep in the mounting holes. Use a Phillips screwdriver of the correct size to avoid stripping the screw slots. It is better to put all removed parts, including screws and plugs, in a separate container so as not to lose them.
Pay special attention to the rubber seals on the doors. They also need to be wiped thoroughly, as mold and food debris often accumulate in the folds. For hard-to-reach places, you can use a cotton swab dipped in a solution of soda or vinegar.
- 🔧 Tools: phillips screwdriver, flat spatula (plastic), water container.
- 🧼 Cleaning products: soda, vinegar, soft sponge, microfiber.
- 🧤 Protection: rubber gloves to protect the skin of your hands from chemicals and cold.
Cleaning the No Frost system and drainage
The most important step is cleaning the evaporator and fan. This is where a “coat” of ice most often forms if the drainage system does not work correctly or if the door has been open for a long time. The fan No Frost circulates cold air, and if its blades become covered with ice or dirt, cooling efficiency will drop sharply.
Gently wipe the fan blades with a damp cloth. Do not wet the fan motor itself with water, so as not to cause a short circuit when turned on. If there is any dirt left on the evaporator, you can remove it with a soft brush or rag.
Be sure to check the drain hole located at the bottom of the back wall (usually in the refrigerator compartment) or under the evaporator. It often becomes clogged with crumbs and mucus, resulting in a puddle under the refrigerator. You can clean it using a special flexible brush or soft wire wrapped in rags.
| Element | What to clean | Frequency | Risk of contamination |
|---|---|---|---|
| Shelves and boxes | Warm water + soda | Once every 1-2 months | Bacteria, odors |
| Seals | Vinegar solution | Once per month | Mold, mildew |
| No Frost fan | Dry/wet cloth | Once a year | Ice, noise, overheating |
| Drainage hole | Brush, pear | When water appears | Clogged, puddle |
⚠️ Attention: When cleaning the drainage tube, proceed carefully. Inserting the tool too deeply or sharply may damage the tube inside the case, which will require disassembling the back wall of the refrigerator.

Care the external surface and condenser
The appearance of the refrigerator Indesit also requires care. If you have a coated model Anti-Fingerprint (stainless steel), use only special polishes for stainless steel or damp microfiber. Abrasive sponges will leave scratches that will become noticeable over time.
Do not forget about the back wall of the refrigerator. There is a capacitor (black grille) located there, which is responsible for heat removal. If dust and pet hair accumulate on it for years, heat exchange is disrupted. The compressor begins to work longer and harder, trying to gain temperature, which leads to excessive energy consumption and wear.
To clean the condenser, use a vacuum cleaner with a soft attachment or a dry brush. This must be done carefully so as not to bend the thin radiator tubes. Regular cleaning of the rear grille is an easy way to extend the life of the compressor.
What to do if noise appears after cleaning?
If after assembly you hear an unusual hum or knocking, check whether the wires or hoses are touching the fan blades. Also make sure that all panel screws are tightened tightly - vibration can be transmitted to loose plastic.
Drying and assembling the refrigerator
After completing all cleaning procedures, you must thoroughly wipe all surfaces dry. Remaining moisture can quickly turn to ice when first used, especially in the freezer. Make sure that the drainage hole allows air to pass freely.
Assemble in the reverse order. Install back panels, secure freezer lid, and insert shelves and drawers. Check that all latches are in place with a characteristic click. Do not turn on the refrigerator immediately.
Let the unit stand with the doors open for another 30-60 minutes after finishing wet cleaning so that the residual condensation completely evaporates. Only after this can you connect the device to the network.
Starting and checking operation
Plug in the refrigerator and set the temperature mode. For models Indesit with electronic control, the settings may be reset after a long period of shutdown, so check the values on the display. Typically, +4°C is recommended for the refrigerator compartment, and -18°C for the freezer compartment.
During the first 2-3 hours, do not load the chambers with food. Allow the equipment to return to operating mode and stabilize the temperature. Listen to the operation of the compressor and fan: there should be no extraneous knocks or loud humming.
If you notice that after cleaning the refrigerator has stopped freezing or is working intermittently, check whether the panels are installed correctly. A loose evaporator lid can disrupt air circulation, which prevents cold from entering the chamber.
Is it possible to wash an Indesit refrigerator without defrosting it for 24 hours?
No, to properly clean the No Frost system, complete defrosting is required. Rapid defrosting with a hairdryer or boiling water can damage plastic parts and sensors. In addition, without thawing, it is impossible to properly clean the drainage and evaporator.
What is the best way to remove unpleasant odors after cleaning?
The best absorbent is activated carbon or a special odor absorber tablet for refrigerators. You can also use an open pack of soda or a saucer of ground coffee. It is better not to use chemical flavorings, as they can kill the smell of spoiled products, masking the problem.
Why does ice quickly appear on the walls again after cleaning?
This may indicate a malfunction of the defrost sensor, heating element or timer, which does not turn on at the right time to melt the ice on the evaporator. Also, the cause may be a door that is not tightly closed or damage to the seal through which moist air enters the chamber.
Do you need to lubricate door hinges after washing?
Yes, if you notice that the door has become tighter to open or creaks. Use silicone lubricant, which is safe for plastic and rubber. Regular machine oil can damage the seals and attract dust.
