How to turn on a Bosch refrigerator correctly: instructions for all models

The first start of the refrigerator Bosch is a crucial moment on which the durability of the equipment and the quality of food storage depend. Even if you have been using refrigerators of other brands for a long time, models Bosch (especially with the system NoFrost or VitaFresh) may have nuances in control. In this article, we will analyze not only the basic steps of switching on, but also the intricacies of setting temperature zones, diagnosing the first hours of operation, as well as typical mistakes that 80% of users make when starting up for the first time.

It is important to understand: the procedure is different for new refrigerators (removal of transport bolts and washing are required) and for equipment after a temporary shutdown (for example, during repairs or moving). We will consider both scenarios separately, and also give recommendations on Economic mode for models with inverter compressors. If your refrigerator Bosch does not respond to button presses or gives an error after turning on, at the end of the article you will find a table of fault codes and ways to eliminate them.

Preparing the Bosch refrigerator for the first time

Before how to plug in a refrigerator requires a few critical steps. Neglecting them can lead to breakdown of the compressor or cooling system in the first days of operation.

Start with inspect the packaging and case: check for dents on the back wall (where the condenser is located) or damage to the rubber seal. Even a slight deformation of the door can cause constant freezing of the evaporator and increased energy consumption by 30%. For models Bosch Serie 6 and Serie 8 pay special attention to temperature sensors - they are often attached to plastic clips that can break off during transportation.

• 🔧 Removing transport bolts: in new refrigerators, the compressor is fixed with 3-4 bolts (usually located on the bottom rear panel). They must be unscrewed - otherwise, when turned on, the compressor will vibrate, which will lead to premature wear.
• 🧼 Washing internal surfaces: use a warm soda solution (1 tablespoon per 1 liter of water) or a special product for refrigerators. Do not use abrasive sponges - they scratch the antibacterial coating AirFresh.
• ⏳ Time for leveling: the refrigerator must stand in an upright position for at least 4 hours after transportation (for models with freon R600a - 6 hours). This is necessary so that the oil in the compressor flows downwards.

⚠️ Attention: If the refrigerator Bosch was transported lying down (for example, in the trunk of a car), before turning it on, it must be kept in an upright position days. Ignoring this rule leads to jamming of the compressor in 90% of cases.

After preparation, install the refrigerator on a flat surface. Use a building level to adjust the legs: misalignment of more than 2° will lead to uneven closing of the doors and increased load on the hinges. For models with a display (for example, Bosch KAN92VI30R), check that the gap between the door and the body is the same around the entire perimeter.

Power connection diagrams: what you can and cannot do

Refrigerators Bosch are sensitive to the quality of the power supply. Even short-term power surges can damage the electronic control unit (especially in models with Home Connect). Here are the key connection rules:

• 🔌 Socket: must be grounded, with a rating of at least 16A. The use of extension cords or tees is prohibited - this is one of the reasons for refusal of warranty repairs.
• ⚡ Voltage stabilizer: required for regions with frequent changes (for example, for dachas). Models with an output voltage of 220V ±5% are suitable (for example, Resanta ACH-500/1-C).
• 🔋 UPS for refrigerators: if the lights are often turned off in your area, use an uninterruptible power supply with a sinusoidal output (for example, APC Back-UPS Pro 900). Battery UPSs with a modified sine wave can damage the inverter compressor.

After connecting to the network, do not turn on the refrigerator immediately. First check:

1. Whether the power indicator on the control panel is lit (for models with a display, the symbol should appear -- or OFF).
2. If there are any extraneous sounds (crackling, hissing) - this may indicate a freon leak.
3. Does the interior lighting work when the door is opened?

Step-by-step instructions: how to turn on a Bosch refrigerator

The startup process depends on the type of control of your model Refrigerators Bosch are divided into three categories:

1. Mechanical control (rotary controls, for example, Bosch KGN33NW20R).
2. Electronic control with buttons (no display, for example, Bosch KGE36AW20R).
3. Touch control with display (models Serie 6/8, for example, Bosch KAN92VI30R).

Let's consider each option in detail.

1. Mechanical control (regulators)

For such models, on the top panel inside the refrigerator compartment there is a rotary regulator with divisions from 1 to 7 (sometimes up to 9). To turn on the refrigerator:

1. Turn the regulator clockwise to position 1 (this is the minimum temperature sufficient for the first start).
2. Wait for a click - this is the relay activated. compressor.
3. After 5-10 minutes, check whether the compressor has begun to make a uniform hum.

If the refrigerator does not respond:

• 🔌 Check whether the plug is firmly inserted into the socket.
• 🔧 Make sure that the transport bolts have been removed.
• 🔄 Try turning the regulator all the way counterclockwise (to position 0), and then back to 1.

2. Electronic control (buttons without display)

In refrigerators with push-button control. (for example, Bosch KGE36AW20R) the algorithm is as follows:

1. Press the button On/Off (usually located on the top panel inside the chamber or on the door).
2. After switching on, the temperature zone indicators will light up (for example, Fridge and Freezer).
3. Use the +/– buttons to set the temperature: for the refrigerator compartment +4°C, for the freezer –18°C.
4. Press Super Cooling (if available) to speed up cooling in the first hours.

If the indicators do not light up:

• 🔋 Check the fuse in the plug (some models have it built-in).
• 🔄 Unplug the refrigerator for 1 minute, then try again.
• 📞 If there is a problem remains, this may indicate a malfunction of the control unit - diagnostics will be required.

3. Touch control (display)

Models with a display (for example, Bosch KAN92VI30R) are turned on as follows:

1. Touch the sensor On/Off (usually indicated by a circle with a vertical line).
2. The display will show Hello or Welcome — this means that the refrigerator is ready to be configured.
3. Swipe or use the buttons to select mode Normal (regular) or Eco (economical).
4. Set the temperature: for zone VitaFresh (if available) — +2°C, for the freezer — –18°C.

If the display does not respond to touches:

• 🧴 Wipe the panel with an alcohol wipe - greasy marks can block the sensors.
• 🔌 Turn off the refrigerator for 5 minutes, then repeat switching on.
• 🔧 If the problem persists, the touchscreen may have failed - the panel will need to be replaced.

Temperature settings: optimal values for Bosch

Incorrectly set temperature is the main reason why refrigerators Bosch begin to make noise, freeze or consume excess electricity. The manufacturer recommends the following parameters:

• 🥦 Refrigerator compartment: +4°C (for zone VitaFresh — +2°C). At this temperature, food is stored longer, and the compressor operates in a gentle mode.
• ❄️ Freezer compartment: –18°C (for quick freezing, you can temporarily install –24°C, but not longer than 24 hours).
• 🍷 Fresh zone (if available): 0°C —ideal for meat, fish and dairy products.

To change the temperature:

1. On models with mechanical control, turn the knob to the desired division (usually 3–4 corresponds +4°C).
2. On electronic panels, press the button Fridge or Freezer, then use the buttons +/– set the value.
3. On touch displays, touch the temperature zone and swipe select the desired value.

⚠️ Attention: If you set the temperature in the freezer lower –20°C, the compressor will work almost non-stop, which will reduce its life by 20-30%. Exception - modes SuperFreezing (use them no longer than 24 hours).

For models with technology NoFrost (for example, Bosch KAN92VI30R), the temperature is distributed automatically, but it still needs to be checked for the first 3 days. To do this:

1. Place the thermometer in a glass of water and place it in the center of the refrigerator. camera.
2. After 12 hours, check the readings - they should be within the limits +3…+5°C.
3. If the temperature is higher +6°C, increase the value on the regulator by 1 division.

First hours of operation: what should happen

After switching on the refrigerator Bosch goes through several startup stages. Knowing these nuances will help you avoid panic if something goes “wrong.” Here is what is considered normal:

• ⏳ The first 30 minutes: the compressor works without stopping, freon gurgling can be heard - this is normal.
• ❄️ After 2-3 hours: frost will appear on the back wall of the refrigerator compartment (in models without NoFrost) - this is a sign of proper operation.
• 🔊 After 6 hours: the compressor should begin to turn off for 10-15 minutes (work/rest cycle - 2:1).

And now - what should alert you:

• 🚨 The compressor does not turn off for more than 8 hours in a row - it is possible freon leak or a thermostat malfunction.
• 💧 A puddle has appeared on the floor under the refrigerator - check drainage hole (it could have become clogged during transportation).
• 🔥 The case gets very hot on the sides - this is normal for the first day, but if the temperature of the walls exceeds 45°C, turn off the refrigerator and check the ventilation.

For models with NoFrost (for example, Bosch KAN92VI30R), fan noise may be heard in the first day - this is normal. If the noise does not stop after 24 hours, check:

• Is the back wall of the refrigerator touching the furniture (there should be a gap of at least 5 cm).
• Is the ventilation duct blocked by food (there should be no bags covering the holes in the freezer).

What to do if the Bosch refrigerator does not turn on?

If, after connecting to the network, the refrigerator does not show any signs of life (the indicators do not light up, the sound of the compressor is not heard), follow these steps:

1. Check the outlet - connect another device to it (for example, a table lamp).

2 Inspect the power cord for damage (especially at the base). plugs).

3. If the refrigerator is new, make sure that the transport fixation of the compressor (bolts on the rear panel) is removed.

4. For models with a display, try resetting the settings: turn off the power for 10 minutes, then turn it on again.

5. If nothing helps, call a technician. reasons: malfunction of the control unit, breakage of the compressor winding or damage to the thermostat.

Typical errors when turning on and how to avoid them

Even experienced users sometimes make mistakes that lead to breakdowns or increased energy consumption. Here are the most common ones:

1. Turning on immediately after transportationAs already mentioned, the refrigerator must stand. 4-6 hours. If you turn it on earlier, the oil from the compressor will not drain down, and it may jam.
2. Ignoring level. Ignoring the refrigerator by just 1° increases the load on the compressor by 10-15%. level
3. Setting the maximum temperature “just in case”**. Mode SuperFreezing or –24°C in the freezer is needed only for quick freezing. Constant operation in this mode reduces the life of the compressor.
4. Loading food immediately after turning on. The refrigerator must cool down to operating temperature (this takes 4-6 hours). If you load warm food earlier, the compressor will work in extreme mode.
5. Use of extension cordsRefrigerators Bosch are sensitive to voltage drop. The extension cord may not provide stable 220V, which will lead to malfunctions of the electronic unit.

Another common mistake is incorrect placement of productsFor example, if in refrigerators with NoFrost the vents are closed with food, the temperature will change. the chamber will become uneven. Here's how to properly load the refrigerator:

• 🥩 Place meat and fish on the bottom shelf (the coldest place).
• 🥛 Dairy products - on the middle shelf.
• 🍎 Fruits and vegetables - in drawers VitaFresh (if any) or on the bottom shelf.
• ❄️ Fill the freezer compartment no more than 70% - this will ensure normal air circulation.

Diagnosis of problems after switching on

If after switching on the refrigerator Bosch does not behave as expected, do not panic. Many “breakdowns” actually occur. in fact, are features of the work or can be easily eliminated without calling a technician. Let's consider the most common situations:

If an error code appears on the display, check it with the table:

For models with the function Home Connect errors may be duplicated in the mobile application. There you can also find a decoding of the code and recommendations for elimination.

⚠️ Attention: If the refrigerator Bosch after turning on makes a loud whistle or hiss, immediately disconnect it from the network. This may be a sign freon leaks -further operation in this condition will lead to compressor failure.

FAQ: Frequently asked questions about turning on Bosch refrigerators

Is it necessary to defrost a new Bosch refrigerator before turning it on for the first time?

No, you do not need to defrost a new refrigerator. It is enough to rinse the internal surfaces with a warm soda solution and wipe dry. Defrosting is required only if the refrigerator was stored at sub-zero temperatures (for example, in an unheated warehouse).

How long should the compressor run when first turned on?

In the first 2-3 hours, the compressor can work continuously - this is normal. Then it should go into a cyclic mode: 10-15 minutes of work, 5-10 minutes of rest. If the compressor does not turn off for more than 8 hours, check the temperature settings or call a specialist.

Is it possible to turn on a Bosch refrigerator after a long period of inactivity (for example, a year)?

Yes, but before turning it on:

1. Rinse the internal surfaces with a solution of vinegar (1:1 with water) to eliminate possible mold.
2. Check the rubber seal - if it has lost elasticity, replace it.
3. Make sure that the drainage hole is not clogged (clean it with a cotton swab).
4. After turning on, do not load the refrigerator with food in the first 6 hours.

If the refrigerator was stored in an unheated room, let it sit warm for 12–24 hours before turning it on.

Why does the Bosch refrigerator make a lot of noise after turning it on?

In the first day of operation, noise can be caused by:

• Freon circulation (gurgling, hissing).
• Fan operation in models with NoFrost.
• Compressor vibration (if the transport bolts are not removed).

If the noise does not stop after 24 hours, check:

• Is the refrigerator level (adjust legs).
• Is the back wall of the furniture touching (there should be a gap of 5-10 cm).
• Are the ventilation holes blocked by products.

For models with an inverter compressor (Bosch Serie 8), the noise should be uniform, without clicks. If you hear sharp sounds, contact the service.

What to do if, after turning on, the Bosch refrigerator does not cool?

The reasons may be the following:

1. Incorrect temperature setting - check the settings (for the refrigerator compartment it should be +4°C, for the freezer - –18°C).
2. Closed vents - in models with NoFrost make sure that food is not blocking the air flow.
3. Freon leak - if the compressor is running, but there is no cold, the cooling system may be damaged. In this case, diagnostics are needed.
4. Malfunction of the thermostat or sensor —if the display shows an error (for example, E01), try turning off the refrigerator for 10 minutes.
5. The room temperature is too high —if the room is hotter +30°C, the refrigerator may not cope. Provide ventilation.
