Refrigerators with a system No Frost ("without frost") are advertised as no-defrost, but that doesn't mean they don't need to be washed. On the contrary: the absence of visible ice often creates the illusion of cleanliness, while bacteria, mold and unpleasant odors accumulate inside. In this article - the only proven No Frost washing algorithm that will not damage the cooling system and will not lead to compressor breakdown.
We will look at how care differs No Frost from conventional refrigerators, what products can be used (and which absolutely cannot), and why even models with data-i="51">from Total No Frost from Bosch or Liebherr you need to clean the drainage hole regularly. Let us separately dwell on typical mistakes due to which, after washing, the refrigerator begins to make noise or cool poorly.
If your refrigerator is equipped with a function Air Flow or Multi Air Flow (like Samsung RB37 or LG GC-B247), the instructions are also suitable for The principles of cleaning ventilation ducts are the same. And at the end of the article you will find a FAQ with answers to questions that are most often asked after the first self-wash.
Why does a No Frost refrigerator need to be washed if there is no ice?
The main misconception of owners No Frost is the belief that the system itself “destroys” all contaminants. In fact, fans only distribute cold air evenly, and moisture condenses on a hidden evaporator (usually behind the back wall). Here's what accumulates inside even with regular use:
- 🦠 Bacteria and mold —on door seals, in egg trays and on chamber walls. They multiply especially quickly in areas with leftover juice, meat or dairy products.
- 🧂 Fatty deposits - from cooked food, which settles on ventilation grilles and interferes with air circulation.
- 🕳️ Clogged drainage hole - leads to the accumulation of water under vegetable boxes (a common problem in Indesit and Atlant).
- 💨 Dust in the condenser - reduces cooling efficiency and increases power consumption by 15-20%.
Manufacturers (for example, Electrolux or Beko) it is recommended to carry out full wash at least once every 3-4 months, and partial (wiping shelves and seals) - once every 2 weeks, which many modern ones have. models. the use of aggressive detergents or a steam generator can damage the antibacterial coating of the internal walls, which many modern models have.
⚠️ Attention: If your refrigerator is equipped with a functionPlasma Cluster(y Sharp) orBioFresh(y Liebherr), check the care section in the instructions - some technologies require special means to preserve properties.
What you will need for washing: list of products and tools
Before start, prepare everything you need. Do not use what you have on hand - the wrong products can damage plastic or rubber parts. Here is a proven list:
| Category | What is suitable | What NOT to use |
|---|---|---|
| Detergents |
|
|
| Tools |
|
|
| Additional |
|

For models with dispenser for water (for example, Samsung RS6***) will be additionally required special brush for cleaning pipes - it can be purchased at service centers or ordered along with the refrigerator. If the dispenser is not cleaned, bacteria Legionellathat are dangerous to health will multiply in it.
Preparing the refrigerator for washing: 5 mandatory steps
Improper preparation is the main cause of breakdowns after washing. Follow this procedure to avoid short circuit or damage No Frost fan:
Unplug the refrigerator (unplug the plug from the socket, the button on the panel is not enough)
Remove all products and shelves (place them in separate bags with ice if washing takes >1 hour)
Remove all removable elements (drawers, wire racks, egg trays)
Cover the drainage hole with cling film (to prevent water from getting in)
Check the temperature of the cleaning solution (not higher than 40°C)
-->
If your model has Display Panel (like LG InstaView), seal it with masking tape to prevent moisture from getting in. For refrigerators with touch control (For example, Samsung Family Hub) before washing, it is better to remove the batteries from the remote control or turn off the panel through the menu Settings → Safety Lock.
Pay special attention door seal - it must be cleaned separately. Bosch Serie 6 and older, the seal is often attached to magnets, which can be accidentally damaged during careless washing. If the rubber is cracked or deformed, it is better to replace it (articles for popular models are at the end of the article).
⚠️ Attention: If the refrigerator has been turned off for less than for 10 minutes before starting washing, wait another 15–20 minutes. This is necessary for the condensate on the evaporator to completely evaporate - otherwise, when you turn it on after washing, the compressor overload protection may work compressor overload protection.
Step-by-step instructions: how to wash the inside of a No Frost refrigerator
Start with upper shelves and gradually go down. So the dirt will not flow onto the already washed surfaces. Here is a detailed algorithm:
-
Cleaning the ceiling and walls of the chamber
Apply detergent to soft sponge and wipe the ceiling of the refrigerator (the most grease accumulates there). data-i="148">models with ventilation grilles models with ventilation grilles (For example, Indesit ITF 118) use a toothbrush dipped in soda solution. Do not press too hard - the grilles are secured with latches and may break.
-
Washing shelves and drawers
Rinse all removable elements under running water with detergent, then rinse and dry for glass shelves (as in Liebherr CP 3313) you can use vinegar solution — he will remove stains. Plastic boxes (especially for Atlant) do not rub with hard sponges - they scratch and then dirt accumulates in microcracks.
-
Cleaning the drainage hole
Remove the protection from the hole (usually a plastic plug) and clean it with a cotton swab dipped in soda solution. In models Samsung RL-** the drainage is often clogged with food particles - if the water does not drain, use syringe with warm water to rinse. Under no circumstances pierce the hole with sharp objects!
-
Caring for the seal
Wipe the door-seal gum with a solution of vinegar (1:1) - this will kill mold and restore elasticity. For hard-to-reach grooves, use cotton swabs. If the seal lost shape (does not fit tightly), it needs to be replaced. For models Bosch KAN9*** rubber with article number is suitable
00644336. -
Processing of ventilation ducts
In refrigerators No Frost an evaporator and a fan are hidden behind the back wall. To get to them, remove the protective panel (usually it is secured with 2-4 latches). Wipe the fan blades with a dry cloth - moisture on the engine can cause corrosion of the bearings. In models Electrolux ENN28*** there is a special hatch for this.
After washing, wipe all surfaces dry microfiber - this will prevent the formation of condensation when turned on. Dry especially carefully the area around the drainage hole and ventilation grilles.
How to wash the No Frost refrigerator outside and rear
Exterior cleaning is often overlooked, but dust on the condenser (grid at the back) increases the load on the compressor and shortens the life of the refrigerator. Here's what you need to do:
- 🧽 Case and handles - wipe with a damp cloth and detergent. For stainless steel (like Liebherr SBSes 7255), use special polishes (Weiman Stainless Steel Cleaner).
- 🔧 Rear wall - move the refrigerator away from the wall, unplug it and vacuum the condenser (grid) with a soft brush. In models with inverter compressor (for example, Samsung Digital Inverter) this is especially important - overheating leads to malfunctions.
- 🔌 Compressor and tubes —wipe with a dry cloth to remove dust. Do not use wet rags in refrigerators! data-i="194">The compressor is often located at the bottom back - this is where the most dirt accumulates. No Frost The compressor is often located at the bottom at the back - this is where the most dirt accumulates.
If there are display or touch buttons on the housing (like LG Instaview Door-in-Door), use alcohol wipes for cleaning. Do not spray liquids directly onto the panel - this may cause a short circuit.
⚠️ Attention: In refrigerators with door cooling system (for example Bosch VitaFresh) do not block the ventilation holes during drying. This can lead to overheating of the fan motor.
What not to do when washing No Frost: 7 critical mistakes
Even experienced users sometimes make these mistakes that lead to breakdowns. Check if you are doing anything from this list:
- ❌ Use hot water - this will deform the plastic and can damage the thermostat. The optimal solution temperature is 30–40°C.
- ❌ Wash the refrigerator without unplugging it — even if the indicators are not lit, voltage remains on the boards. In models with display (for example, Samsung RF23**) this can lead to firmware failure.
- ❌ Forgetting to dry the seal —moisture in the grooves of the rubber leads to the appearance of mold and an unpleasant odor. In refrigerators No Frost owners often encounter this problem Indesit BIAA 13.
- ❌ Clean the fan with sharp objects —blades are made of thin plastic and break easily. To clean, use a brush with soft bristles.
- ❌ Try to defrost No Frost forcibly - unlike drip systems, here the ice melts automatically. If frost appears on the back wall, this is a sign. malfunction of the defrost sensor.
- ❌ Use flavored ones. napkins - they leave a film that interferes with air circulation. It is better to use odorless products.
- ❌ Put the refrigerator in place until it dries completely -moisture under the bottom can cause corrosion of metal parts. Wait at least 1-2 hours.
If the refrigerator becomes cold after washing more noise or poor coolingcheck:
- If water has gotten on the fan (it may make a creaking sound when rotating).
- Not clogged Is there a drainage hole (if so, clean it again).
- Are the ventilation grilles in place correctly (their displacement disrupts air circulation).
How often to wash a No Frost refrigerator: care schedule
Manufacturers recommend different intervals depending on the model. Here is an approximate schedule:
| Type of care | Frequency | What do |
|---|---|---|
| Weekly cleaning | once a week |
|
| Deep washing | once every 3-4 months |
|
| Cleaning the condenser | once every 6 months |
|
| Replacing the seal | once every 2-3 years |
|
For refrigerators with freshness zones (for example, Liebherr BioFresh) or antibacterial coating (like Sharp SJ-F***), the schedule may differ - check the instructions for the section Maintenance Schedule.
If there are allergy sufferers or small children in the house, it is better to wash more often (once every 2 months), since the system No Frost can accumulate dust and mold spores, which then spread throughout the kitchen with air flow.
What will happen if you never wash the No Frost refrigerator?
Without regular cleaning in the No Frost refrigerator:
1. Electricity consumption increases by 30-40% due to clogged filters and condenser.
2. Bacteria multiply in the drainage system, causing an unpleasant odor (a common problem with Atlant MXM-1835-80).
3. The fan begins to wear out, which leads to its breakdown after 3-5 years (replacement cost - from 4,000 rubles).
4. Mucus forms on the walls, which can get on food and cause food poisoning.
5. In models with electronic control (for example, Bosch KGE39***) dust on the boards can cause display malfunctions.
FAQ: answers to frequently asked questions about washing No Frost
Is it possible to wash a No Frost refrigerator with a steam generator?
No, this is strictly prohibited:
- Deform plastic parts (especially for models Indesit i Atlant).
- Damage the antibacterial coating of the walls.
- Damage electronic components (in refrigerators with a display).
Exception - steam cleaners with temperature up to 60°C and a special attachment for equipment, but even using them is not recommended without experience.
Why did the No Frost refrigerator begin to work loudly after washing?
The reasons may be the following:
- The fan blades touch the ice — if during washing water got on the evaporator and froze, you need to defrost the refrigerator for. 12–24 hours.
- Ventilation grilles have moved —check their position (they should fit tightly, without gaps).
- Dust got into the fan bearing —disassembly and cleaning required (better call a technician).
- The compressor is working hard —if the refrigerator was not disconnected from the mains during washing, the starting capacitor could burn out.
If the noise does not go away after 1-2 days, contact the service center.
How to clean the drain hole if it is strong clogged?
For severe blockages:
- Turn off the refrigerator and remove all shelves.
- Remove the protective cover of the drainage hole (usually it simply snaps off).
- Use flexible brush (can be bought at a hardware store) or syringe with warm water.
- If the blockage is deep, pour a soda solution into the hole (1 tsp per 100 ml of water) and leave for 15 minutes, then rinse.
In models Samsung i LG the drainage tube often becomes clogged due to the design features - if cleaning does not help, the tube may need to be replaced (contact service).
Is it necessary to defrost a No Frost refrigerator before washing?
No, under normal conditions there is no need to defrost No Frost. The system itself thaws the ice during operation. However, if:
- A thick layer of frost is visible on the back wall - this is a sign breakage (the defrost sensor or heating element is faulty).
- The refrigerator has not been washed for a long time (more than a year), and a lot of dirt has accumulated inside - you can leave it unplugged for 1-2 hours to ventilate.
Forced defrosting (for example, with a hairdryer) can damage the system No Frost!
What products best remove odors from a No Frost refrigerator?
Effective methods (tested on models Bosch, Samsung, LG):
- Activated carbon - place 5-6 tablets in a small container on the middle shelf.
- Baking soda - place the open pack on the bottom shelf for 12 hours.
- Lemon juice —wipe the walls with a solution (1 tablespoon of juice per 1 liter of water), then rinse with clean water.
- Special absorbers —for example, Topperr 3104 or Unicum.
Do not use air fresheners with a strong aroma - they can be absorbed into the plastic and ruin the taste of the food.
