Step-by-step instructions: how to properly defrost a two-chamber Westfrost refrigerator

Two-chamber refrigerators Westfrost are popular due to their reliability and functionality, but even the most modern models require periodic defrosting. Many owners are faced with a dilemma: how to carry out the procedure correctly so as not to damage the equipment or spoil the products? This issue is especially relevant for models with a system No Frost and traditional drip defrosting - they have different maintenance nuances.

In this article you will find step-by-step instructions taking into account the type of your refrigerator, tips to speed up the process and answers to frequently asked questions. We will also look at typical mistakes that lead to compressor breakdowns or seal leaks. If you have never defrosted a refrigerator yourself before, don’t worry: our recommendations will help you cope with the task without calling a specialist.

Modern two-chamber models Westfrost (for example, series WFN 3855 or WF 5200) are equipped with different cooling systems. The frequency and method of defrosting depends on this. Thus, refrigerators with No Frost in the freezer theoretically do not require manual defrosting, but in practice ice can still accumulate due to malfunctions or improper operation. And models with a drip system (Direct Cool) need to be defrosted at least 1-2 times a year, even if the manufacturer claims otherwise.

Before starting the procedure, check instructions for your model - there may be specific recommendations. For example, refrigerators Westfrost Premium with electronic control have a quick defrost mode, which is activated through the menu. If you have a mechanical control, the process will be completely manual.

1. Preparing for defrosting: what needs to be done in advance

Do not start defrosting spontaneously - this can lead to spoilage of food or damage to equipment. One 12-24 hours before the procedure, follow several important steps:

• 📦 Sort the food: take out all perishable foods (meat, fish, dairy products) and put them in a cooler bag or thermal container. Vegetables and fruits can be temporarily moved to a cool place (for example, on a balcony in winter).
• ❄️ Set the minimum temperature: if your refrigerator Westfrost has a regulator (for example, in models WF 3900), turn it to the mark MIN or 1 6-8 hours before defrosting. This will reduce the amount of ice.
• 🧊 Prepare containers for water: take several deep basins or baking trays to collect melt water. In models with a drip system, water will flow down the back wall, and No Frost will accumulate in the tray under the freezer.
• 🧽 Prepare detergents: after defrosting, the refrigerator will need to be washed. A weak solution of soda is suitable (2 tablespoons per 1 liter of water) or a special product for refrigerators (for example, Topperr 3101).

If you have a model with separate compressors (for example, Westfrost WF 5500 Dual Cooling), you can defrost the chambers one by one. To do this, turn off the power only one chamber, transferring the products to the second. This will reduce the downtime of the refrigerator.

Important! Do not use metal containers to collect water - they can scratch plastic or enamel. Also avoid hot water to speed up the process: a sudden temperature change can damage the door seals.

2. Step-by-step instructions: how to defrost a Westfrost refrigerator

The defrosting process depends on the type of cooling system. Below is a universal instruction suitable for most two-chamber models Westfrost (including WFN 3855, WF 4200, WF 5200 and others). If your refrigerator is equipped with the function Super Frost or Fast Freeze, first disable these modes through the panel. controls.

Unplug the refrigerator from the outlet

Take out all the food and shelves

Place containers to collect water

Open the doors wide open-->

Step 1. Disconnection power supply

Unplug the refrigerator from the socket. If the socket is in a hard-to-reach place (for example, behind the refrigerator), use an extension cord with a switch. Never pull the cord - this can damage the plug contacts, especially in models with a thick power cord (like this Westfrost Premium).

Step 2. Removing products and shelves

Take out all removable elements: shelves, containers, grilles. They also need to be washed separately. remove the plastic panels - condensation often accumulates under them. freshness zones (For example, BioFresh in the series WF 5000) carefully remove the plastic panels - condensation often accumulates under them.

Step 3. Collection of melt water

In refrigerators Westfrost with a drip system, water flows down the back wall into a special tray (usually located above compressor). In models No Frost ice melts directly in the freezer, and water can spill onto the floor. To avoid a flood:

• 💧 Place a wide basin under the freezer.
• 🧻 Place towels or towels around the refrigerator. rags.
• 🔧 If a drain hose was included (available in some models Westfrost), connect it to the drainage hole and lead it to the sink.

Step 4. Accelerating defrosting

Natural It may take 4-12 hours (depending on the amount of ice) to melt the ice. To speed up the process:

• 💨 Point a fan at the open chambers (but not at the seals!).
• 🧊 Place a pan with warm water (temperature no higher 40°C).
• 🧽 Periodically remove broken pieces of ice with a wooden spatula (do not use metal objects!).

⚠️ Attention! Do not try to break off the ice with a knife or fork - this may puncture the evaporator (especially in models No Frost), which will lead to leakage freon and expensive repairs.

Step 5. Washing and drying

After the ice has completely melted:

1. Rinse all surfaces inside with a solution of soda or vinegar (1:1 with water).
2. Wipe the door seals with a mild soap solution - this will prevent them from cracking.
3. Dry the refrigerator with a towel or leave the doors open for 1-2 hours.

Step 6. Turning on the refrigerator

Before turning on check:

• ✅ All shelves and containers are in place.
• ✅ The doors close tightly (the seals are not warped).
• ✅ There is no water in the pan (if there is, remove it).

Connect the refrigerator to network and let it work 2-3 hours in an empty state so that the temperature stabilizes. Only then load the products.

3. How long does defrosting take: norms for Westfrost

Defrosting time depends on three factors:

1. Thickness of the ice layer: with a layer up to 5 mm - 1-2 hours, with 1-2 cm - 4-6 hours, with thick ice (from 3 cm) - up to 10-12 hours.
2. Type of cooling system:
   • 🔹 No Frost: 2-5 hours (ice melts evenly).
   • 🔹 Drip system: 4-8 hours (ice accumulates on the back wall).

Room temperature: in a cool room (18-20°C) the process will take 20-30% longer than with 25°C.

B refrigerators Westfrost with a function Super Cooling (for example, WF 5500) ice may take longer to melt due to a lower initial temperature. If the process takes more than 12 hours, check:

• 🔌 Is the power turned off correctly (the indicators on the panel should go out).
• 🚪 Are the doors closed tightly - even a small gap slows down the melting.
• 🌡️ Room temperature (if <16°C defrosting can take up to a day).

⚠️ Attention! If after 12 hours the ice has not melted, and frost or condensation appears on the back wall of the refrigerator, this may indicate thermostat malfunction or clogged drainage. In this case, diagnostics by a specialist is required.

4. Defrosting features for models with No Frost

Refrigerators Westfrost with a system No Frost (for example, WFN 3855, WF 4200 NF) theoretically do not require manual defrosting, since the ice is removed automatically while the compressor is running. However, in practice, defrosting is still needed in the following cases:

• 🛑 A thick layer of ice (more than 5 mm) appeared on the walls of the freezer.
• 🛑 The refrigerator began to make more noise than usual (this may indicate icing of the fan).
• 🛑 An unpleasant odor or mold in the seals.

How to defrost No Frost correctly:

1. Unplug the refrigerator and remove all food.
2. Make sure that the ventilation holes (usually located on the back wall of the freezer) are not clogged with ice. If so, carefully remove the ice with a plastic spatula.
3. Wipe all surfaces, including evaporator (the metal grill in the freezer).
4. Check the drainage hole (located at the bottom of the back wall) - if it is clogged, clean it with a cotton swab or a special brush.

In models Westfrost with Full No Frost (cooling both chambers without frost), defrosting takes 1.5-3 hours. After the procedure, turn on the refrigerator and wait until it reaches operating temperature (-18°C in the freezer compartment). Only then load the products.

What will happen if you do not defrost No Frost?

Even in No Frost systems, condensation and micro-ice accumulate on the evaporator over time. If you ignore defrosting, this will lead to:

- Increased energy consumption (the compressor runs longer).

- The appearance of an unpleasant odor due to the growth of bacteria in the drainage system.

- Fan breakdown (if ice blocks its blades).

- Reduced cooling efficiency (the temperature in the chambers will be higher than the set one).

5. Typical mistakes and how to avoid them

Even experienced users sometimes make mistakes when defrosting, which lead to breakdowns or shortening the life of the refrigerator. Here are the most common of them:

• ❌ Use of sharp objects for chipping ice. This may puncture the evaporator or damage the plastic parts. Properly: use a plastic spatula or wooden spoon.
• ❌ Sudden temperature changes (for example, pouring boiling water over it). This deforms the seals and can cause cracks in the plastic. How to do it: use warm water (30-40°C) or a hair dryer at minimum power.
• ❌ Incomplete drying before turning on. Remaining moisture leads to rapid re-icing. How to do it correctly: wipe all surfaces dry and leave the doors open for 1-2 hours.
• ❌ Ignoring the drainage hole. A clogged drainage causes water to accumulate at the bottom of the chamber and an unpleasant odor. How to do it correctly: clean the hole with a cotton swab or rinse it with warm water.
• ❌ Turning on the refrigerator immediately after defrosting. The compressor needs time to adapt to the load. How to do it correctly: wait 10-15 minutes before turning on.

Another common mistake is incorrect temperature setting after defrosting. In refrigerators Westfrost optimal settings:

• 🥶 Freezer compartment: -18°C (or 3-4 division on a mechanical regulator).
• ❄️ Refrigerator compartment: +4°C (or 2-3 division).

⚠️ Attention! If after defrosting the refrigerator does not turn on or makes unusual sounds (for example, clicks without starting compressor), do not try to repair it yourself. This may indicate faulty start relay or freon leak - in such cases, professional diagnostics are required.

6. How often do you need to defrost a Westfrost refrigerator

The frequency of defrosting depends on the type of cooling system and operating conditions. Here are the recommendations for different models Westfrost:

If you live in a region with high humidity or often open the refrigerator door, you will have to defrost more often - approximately every 3-4 monthsThe frequency is also affected by:

• 🍳 Type of products: if you store a lot of liquids in open containers (soups, compotes), humidity increases in the chamber.
• 🚪 Door opening frequency: in families with children, the refrigerator is opened 2-3 times more often, which accelerates the formation of ice.
• 🌡️ Room temperature: if the kitchen is hot (>25°C), the compressor works more intense, and the ice grows faster.

In refrigerators Westfrost s defrosting indicator (for example, WF 5500) the ❄️ icon lights up on the display when it’s time to carry out the procedure. If there is no such function, focus on the thickness of the ice: as soon as it exceeds 3-5 mm, it’s time to act.

7. Care after defrosting: how to extend the service life. data-i="288">To make the refrigerator

To the refrigerator Westfrost last longer, after defrosting, follow a few simple steps:

• 🧴 Lubricate the seals silicone grease or glycerin - this will prevent them from cracking and ensure a tight fit.
• 🧼 Rinse the drainage hole soda solution (1 teaspoon per glass of water) to eliminate bacteria.
• 📝 Keep a defrost log: write down the dates of the procedures and any malfunctions noticed (noises, uneven cooling). defrost log
• 🔄 Check the settings: after switching on, make sure that the temperature in the chambers is normal (+4°C in the refrigerator and -18°C in the freezer).

If your refrigerator is equipped with antibacterial coating (for example, BioShield models Westfrost Premium), use only mild detergents without abrasives for washing. Aggressive chemistry (for example, Domestos) can damage the coating.

Also pay attention to location of products after defrosting:

• 🥩 Store meat and fish in the lower part of the freezer (it’s colder there).
• 🥛 Dairy products - on the middle shelves of the refrigerator.
• 🍎 Fruits and vegetables - in special containers (if yes) or on the bottom shelf.

Helpful advice: if your refrigerator Westfrost has a function Holiday (vacation mode), turn it on when you leave for a long time. This will reduce energy consumption and reduce the load on the compressor.

8. Frequently asked questions about defrosting Westfrost refrigerators

❓ Is it possible to defrost a Westfrost refrigerator with a hair dryer?

Yes, but with caution. Use a hair dryer on minimum power and keep it at a distance 20-30 cm from surfaces. Do not direct hot air at seals or plastic parts as they may become deformed. It is better to use a hairdryer in cold air or warm (40°C).

❓ Why does the refrigerator not work after defrosting? cools?

There may be several reasons:

1. The compressor did not turn on due to a faulty thermostat.
2. Happened freon leak (if damage occurred during defrosting evaporator).
3. Clogged drain holeand water is blocking the operation of the system.
4. In refrigerators with electronic control it could go astray temperature sensor.

First, check if the power indicator is on. If so, but the refrigerator is not freezing, call a technician. Repairing it yourself can aggravate the problem.

❓ Is it necessary to defrost a new Westfrost refrigerator?

No, if it has just been purchased and turned on for the first time. Modern models (for example, Westfrost WFN 3855go on sale with already dried chambers. You need to defrost a new refrigerator only if:

• It was left turned off in a damp room (risk of mold).
• The conditions were violated during transportation. (for example, the refrigerator was transported in winter without insulation).

In other cases, just wash the chambers before the first use.

❓ How to defrost a Westfrost refrigerator if it has two compressors?

In models with separate compressors (for example, Westfrost WF 5500 Dual Cooling), you can defrost the chambers one by one:

1. Turn off the power to one chamber (usually there is a separate switch or button).
2. Transfer the products from the defrosted chamber to another.
3. Carry out defrosting as usual.
4. After completion, repeat the procedure for the second chamber.

This will avoid prolonged downtime of the refrigerator.

❓ What to do if there is a smell in the refrigerator after defrosting?

An unpleasant odor may appear due to:

• Food residues in the drainage system.
• Mold on the seals or back wall.
• Insufficient drying after washing.

How eliminate:

1. Rinse all surfaces with a solution of vinegar (1:1 with water).
2. Place an open pack of soda or activated carbon in the refrigerator for 12 hours.
3. Check the drainage hole - if it is clogged, clean it with a cotton swab.
