Ariston No Frost refrigerator: how to turn it on correctly after purchase, defrosting or shutdown

The system No Frost in refrigerators Ariston simplifies maintenance, but the first start-up or re-starting after defrosting often raises questions. Incorrect actions can lead to compressor malfunction, ice formation in the ventilation ducts, or even damage to the electronic module. This article will help you avoid common mistakes: from preparation before switching on to checking the functionality of all modes.

A feature of the models Ariston c No Frost is automatic air circulation and no need for manual defrosting. However, this does not mean that you can simply plug the refrigerator into a power outlet and forget about it. For example, after transportation it is necessary to wait minimum 4 hours before turning it on so that the oil in the compressor returns to working condition. And if the appliance is turned off for cleaning, it is important to check the evaporator for the presence of residual ice - its presence can block the fan.

Next, we will look at step-by-step instructions for different situations: first turn on, restarting after defrosting, and also what to do if the refrigerator does not respond to pressing buttons. We will pay special attention to models with an electronic display (Ariston MBA 2200 NF, HBM 1182.1 NF) and mechanical regulators (Ariston BCB 33).

Preparing the Ariston No Frost refrigerator for the first time

The new refrigerator cannot be turned on immediately after delivery. Here's what you need to do first:

• 📦 Unpack and inspect the case for damage. Pay special attention to the back wall - the compressor and condenser are located there.
• ⏳ Wait 4-6 hours (in winter up to 12 hours) so that the refrigerant and oil in the compressor stabilize. This rule is true even for models with the system. No Frost.
• 🧹 Wipe the internal surfaces a weak solution of soda (1 tablespoon per 1 liter of water). Do not use aggressive detergents - they may damage the plastic.
• 🔌 Check the socket: it must be grounded and withstand a load of at least 10 A. For models with an inverter compressor (Ariston HBM 20524) a surge protector is recommended.

If the refrigerator was stored or transported at subzero temperatures, the waiting time before turning on increases to 12–24 hoursThis is due to the risk of thickening of the oil in the compressor, which can lead to overheating.

⚠️ Attention: If there are transport bolts on the back wall of the refrigerator (usually in models with a freezer), they must be removed before turning on the compressor with fixed bolts leads to vibrations and premature wear. Ariston There are transport bolts (usually in models with a freezer), they must be removed before switching on. Operating the compressor with fixed bolts leads to vibrations and premature wear.

Step-by-step instructions: how to turn on the Ariston No Frost refrigerator

The turning on process depends on the type of control. Below is the algorithm for both options.

For models with an electronic display (Ariston MBA 2200 NF, HBM 1182.1 NF)

1. Connect the refrigerator to the network. The display should light up (usually flashes --°C or OFF).
2. Press the button ON/OFF (or hold it for 3 seconds in some models). The current temperature will appear on the screen.
3. Use the +/– or ▲/▼ set the target temperature:
   • For the refrigerator compartment: +4…+6°C.
   • For the freezer: –18…–20°C.

Activate the mode Super Freeze (if quick freezing is required) with the button with the image of a snowflake ❄️ It will turn off automatically after. 24–48 hours.

For models with mechanical control (Ariston BCB 33, MB 1941)

1. Turn the thermostat (usually located in the upper part of the refrigerator compartment) to the position 1–2 (minimum cooling).
2. If there is a separate regulator for the freezer, set it to –18°C (mark *** or middle position).
3. Wait for a characteristic click - this is a signal to start the compressor. In models with No Frost the fan should also start (light air noise).

In both cases, after turning on the refrigerator Ariston may not cool the first ones 1–2 hours this is normal. The compressor gains operating temperature gradually.

What to do if the Ariston refrigerator No Frost does not turn on

If the refrigerator does not respond after connecting to the network, check the following:

If the refrigerator Ariston makes a hum, but does not cool, the following problems are possible:

• 🔌 Fan jammed No Frost (often due to ice or a foreign object).
• ❄️ Refrigerant leak —the compressor runs nonstop, but the temperature does not drop.
• 🔥 Thermal sensor has burnt out —an error may appear on the display E3 or E4.

⚠️ Attention: If after turning on the refrigerator Ariston immediately shows an error E1 or E5, do not try to reset it by repeatedly pressing the buttons. These codes indicate critical faults (for example, a short circuit in the compressor circuit), and further manipulations can aggravate the breakdown.

What does error E2 mean in Ariston No Frost refrigerators?

Error E2 indicates a problem with temperature sensor of the refrigerator compartment. Most often this is caused by an open circuit or oxidation of the contacts. In 30% of cases, a simple reboot (shutdown for 5 minutes) helps, but if the error returns, the sensor must be replaced.

How to turn on the Ariston No Frost refrigerator after defrosting

Even refrigerators with the system No Frost require periodic defrosting (every 1-2 years) to clean the ventilation ducts. After the procedure, switching on has some nuances:

1. Make sure that there is no ice left on the evaporator (the back wall of the freezer). If there is ice, wait for it to completely melt.
2. Wipe everything dry. surface. Moisture on the sensors can cause false alarms of the defrosting system.
3. Connect the refrigerator to the power supply and turn it on in the standard way (see section above).
4. Activate the mode Super Cool (if available) to quickly restore the temperature.

After defrosting the compressor can work without stopping up to 8 hours this is normal. However, if after 10-12 hours the temperature in the chambers has not reached the set values, check:

• 🔄 Door closure tightness —even a small gap disrupts air circulation.
• ❄️ Fan operation —put your ear to the back wall: a uniform noise should be heard.
• 📉 Room temperature —if the room is hotter +32°C, the refrigerator may not be able to cope with the load.

Temperature settings in Ariston No Frost refrigerators

Optimal temperature conditions for models Ariston:

• 🥦 Refrigerator compartment: +4...+5°C (regulator at 2–3 or 37°F on the display).
• ❄️ Freezer compartment: –18°C (mark *** or –2°F).
• ⚡ Super Freeze mode: –24…–26°C (turns on for 24 hours for quick freezing).

In models with electronic control (Ariston HBM 1182.1 NF), the temperature is adjusted in steps 1°C, in mechanical (Ariston BCB 33) - in steps (usually 5 positions). To check the accuracy of the settings, use a separate thermometer:

1. Place the thermometer in a glass of water and place it in the center of the refrigerator.
2. After 8 hours, compare the readings with the display. A discrepancy of more 2°C indicates a malfunction. sensor.

⚠️ Attention: In refrigerators Ariston with the function Holiday (vacation), when this mode is activated, the temperature in the refrigerator compartment automatically rises to +12...+15°C. This can lead to food spoilage if you forget to turn off the function after returning.

Typical errors when turning on the Ariston No Frost refrigerator

Even experienced users sometimes make mistakes that lead to breakdowns. Here are the most common:

• ⏱️ Switching on immediately after transportation - risk of compressor water hammer.
• 🔌 Using an extension cord —can cause a voltage drop and failure of the electronic module.
• ❄️ Ignoring ice in the freezer after defrosting—blocks the fan No Frost.
• 📱 Setting the temperature by feelingand not by thermometer— leads to freezing or insufficient cooling.
• 🚪 Overloading the door with products - breaks the tightness and increases the load on the compressor.

One of the most dangerous mistakes is forced shutdown of the refrigerator during the defrosting cycle (usually occurs once every 8-12 hours). At this moment, the evaporator heater is activated, and a sudden power outage can damage it. You can recognize the defrosting cycle by the following signs:

• The compressor is silent, but the fan is silent. is working.
• Water may drip from the back wall of the freezer (this is normal).
• The indicator may flash on the display Defrost.

Frequently asked questions about turning on Ariston No Frost refrigerators

How long should the compressor run after the first turn on?

In new refrigerators Ariston the compressor can operate continuously up to 8–12 hours after the first turn on. This is due to the need to enter operating mode and cool the empty chambers. If after 12 hours the compressor does not turn off, check:

• The tightness of the doors.
• The room temperature (optimal). +16…+30°C).
• Presence of product in mode Super Freeze (it can block automatic shutdown).

Why, after turning on, does the Ariston refrigerator beep and the indicator blinks?

A sound signal and the indicator blinks Alarm or Door Open indicate:

• Open door (check the seal).
• Sharp increase in temperature in the chamber (for example, after loading warm products).
• Sensor failure (required reboot or replacement).

To reset the signal, tilt the refrigerator slightly forward (1-2°) or press the button Alarm Reset (if available).

Is it possible to turn on the Ariston No Frost refrigerator without grounding?

Technically yes, but this violates safety rules. In electronically controlled refrigerators (Ariston MBA 2200 NF), lack of grounding can lead to:

• Interference with the display.
• Risk of electric shock when touched metal parts.
• Failure of the control board during voltage surges.

If there is no grounding in the house, use RCD (residual current device) with leakage current 30 mA.

How to turn on an Ariston refrigerator after a long period of inactivity (more than 1 month)?

If the refrigerator has been turned off for more than a month:

1. Check the door seals for cracks or deformations.
2. Make sure that the drainage hole (at the bottom of the refrigerator compartment) there are no blockages.
3. Turn on the refrigerator in 1 (minimum cooling) mode for 2-3 hours, then set the operating parameters.

If after turning on the compressor does not start, it is possible refrigerant leak through microcracks in the circuit.

What to do if, after turning on, the Ariston No Frost refrigerator makes a lot of noise?

The noise level of refrigerators Ariston s No Frost is 40–45 dB. If the noise is stronger:

• 🔊 Compressor humming - normal in the first hours of operation.
• 💨 Fan noise - check if it is blocked by ice or food.
• 🔩 Rattling —inspect the compressor mounting and transport bolts.

If the noise is accompanied by vibration, adjust the legs of the refrigerator according to the level.
