After carrying out the procedure for completely defrosting your refrigerator Indesit the most critical moment comes, on which the further performance of the compressor depends. Many owners of household appliances make the fatal mistake of starting the unit immediately after wiping the shelves and removing any remaining melt water. This action can lead to serious damage, since the internal systems are not yet ready for the load.
The waiting time directly depends on how long the defrosting lasted and at what temperature it was carried out. If you defrosted the device naturally during the day, then the process of equalizing the temperature conditions will take less time than when using a hairdryer or hot water. Main rule says: haste in this matter is unacceptable, since the refrigerant and oil in the compressor must return to normal.
In this article We will analyze in detail the physical processes occurring inside the cooling system and determine the exact time intervals for various situations. You will learn why modern models with a No Frost system require a different approach than classic two-chamber refrigerators with a drip system. Understanding these nuances will help extend the service life of your Indesit for many years.
⚠️ Attention: It is strictly forbidden to plug in the device if there are still ice crusts inside the chambers or accumulations of water in hard-to-reach places. This can cause a short circuit or water hammer in the system.
Physical processes: why you need to wait
To understand the need for a pause before starting, you need to look inside the refrigeration unit. During the defrosting process, freon, which is in a gaseous state, is mixed with oil, which should be located exclusively in the compressor crankcase. If the power is suddenly turned on refrigeration unit it may not be able to cope with pumping this mixture, which will lead to blockage of the capillary tube.
In addition, during washing and defrosting, condensation or moisture could get into the thermal insulation layer and onto the electrical contacts. Even if everything looks dry on the outside, the microscopic drops of water inside the case should completely evaporate. An attempt to apply voltage to the wet contacts of sensors or a thermostat often causes failure of the control electronics.
The temperature gradient also plays an important role. If you washed the refrigerator with warm water and then try to start it at maximum power, a sharp temperature change will create excess pressure in the tube system. Indesit, like any other equipment, requires a smooth entry into operating mode after a long period of inactivity.
What happens to the oil when turned on?
If the oil is left idle for a long time in a horizontal position, compressor may leak into the cooling circuit. If you turn on the refrigerator immediately, the compressor will try to compress the liquid (oil), which will lead to water hammer and jamming of the piston group. A pause is necessary for the oil to drain back into the crankcase.
Standard waiting time for different models
The answer to the question of how long it takes for the refrigerator to turn on after defrosting Indesitvaries depending on the specific model and type of cooling system. For classic two-chamber models with manual defrosting or drip system, the minimum downtime is from 2 to 4 hours. This time is usually enough for moisture to evaporate and pressure to stabilize.
The situation with models equipped with the system No Frostis somewhat different. Such devices have a more complex system of air ducts and fans. If you performed a deep defrost with complete defrosting of the evaporator located behind the rear wall, the waiting time should be increased to 6-8 hours. This ensures that there is no moisture left in the hidden cavities, which, when frozen, will turn into ice and block the fan.
There is also a dependence on the duration of the previous shutdown. If the refrigerator was turned off for only a couple of hours for a quick wash, 1 hour of waiting is enough. If the unit has been left without power for a day or more, especially in a cold room, it needs more time to acclimatize to room temperature before the first start.
The influence of ambient temperature
The temperature in the room where the equipment is located significantly affects the drying time of the internal components. If you defrosted in winter in an unheated room or on a balcony, the waiting time should be increased. In cold air, moisture evaporates much more slowly, and the risk of condensation inside electrical components increases.
The optimal temperature for the defrosting procedure and subsequent drying is considered to be a range from +18 to +25 degrees Celsius. Under such conditions, the process of moisture evaporation proceeds at a natural pace. If the room is cool, it is recommended to additionally ventilate the room or use a heater (without directing a stream of hot air directly to the plastic of the refrigerator) to speed up the process.
Critically important: If the refrigerator was brought in from the cold, it should not be turned on for at least 4-6 hours, regardless of whether you defrosted it or not. A sudden start of the compressor in the cold will lead to solidification of the oil and instant breakdown of the mechanism.
In hot weather, when the temperature in the kitchen exceeds +30 degrees, moisture evaporates faster, but the load on the cooling system increases at the first start. In this case, it is recommended to wait the standard 4 hours, but before turning on, make sure that the rear radiator grille is also completely dry.
Step-by-step instructions: preparing for the first start
Before inserting the plug into the socket, it is necessary to carry out a final inspection. Make sure that all removable elements - shelves, drawers, vegetable containers - are in place and securely fixed. Check that the doors close tightly and the rubber sealing profile fits around the entire perimeter without gaps.
☑️ Check before turning on
Next you should inspect the compressor compartment (usually located lower back). There should be no traces of water or high humidity. If you used a vacuum cleaner to remove water from the drain hole, make sure the hose is disconnected and the hole is clear. drainage is a common cause of subsequent ice formation.
Only after visual confirmation of the dryness of all components can the power be connected. It is recommended to use a separate grounded outlet, avoiding the use of extension cords or tees, which can become a source of heating and sparking during inrush currents.
⚠️ Attention: Do not try to speed up drying with a hairdryer by directing a stream of hot air at plastic parts or rubber seals. Deformation of the plastic or melting of the seal will lead to loss of seal of the chamber.
Algorithm for first switching on and loading
After you have switched on Indesit to the network, do not rush to load the products. Let the refrigerator idle. This is necessary so that it reaches operating temperature and turns off (or switches to temperature maintenance mode) at least once. Depending on the volume of the chambers, this process can take from 1.5 to 3 hours.
While running idle, listen to the sounds. A smooth hum of the compressor and periodic gurgling of the refrigerant is considered normal. If you hear loud knocking, grinding or whistling noises, unplug the appliance immediately. These sounds may indicate incorrect installation (feet are not adjusted) or a foreign object has entered the ventilation system.
After the first automatic shutdown of the compressor, you can start loading. Place food evenly without blocking the vents (if your model has them) or pressing food against the back of the chamber. This will ensure proper circulation of cold air.
Waiting time table
For ease of perception of information, we have systematized data on the required downtime depending on the type of defrosting and model. Use this table as a guide, but always consider the specific conditions in your room.
| Defrosting type | Refrigerator model | Minimum waiting time | Recommended time |
|---|---|---|---|
| Natural (24 hours) | Indesit two-chamber (Drop) | 2 hours | 4 hours |
| Forced (hairdryer/steam) | Indesit two-chamber (Drop) | 4 hours | 6 hours |
| Natural (24 hours) | Indesit No Frost | 4 hours | 8 hours |
| Express wash (1 hour) | Any model | 30 minutes | 1 hour |
| After transportation | Any model | 4 hours | 8-12 hours |
Please note that the time for models No Frost is indicated with a margin, since moisture in these systems may be retained in the air supply channels. Ignoring these recommendations can lead to the formation of an ice plug in the evaporator within a few days after switching on.
Common mistakes and their consequences
One of the most common mistakes is trying to turn on the refrigerator without waiting for the drainage hole to completely dry. The water remaining in the drain will freeze and turn into an ice plug during the first cooling cycle. As a result, condensation will stop leaving and will begin to accumulate at the bottom of the refrigerator compartment or, worse, will flow onto the floor.
Another mistake is setting the temperature to a minimum immediately after turning it on. Many users, wanting to cool food faster, set the regulator to maximum cooling. For Indesit this is stress, especially after downtime. It is better to set the average value, let the system stabilize, and then, if necessary, adjust the settings.
Some users neglect to level the refrigerator horizontally. After a long defrosting and washing, the legs could get lost. Operation of a skewed unit results in improper oil flow and noise. Use a building level or simply adjust the legs so that the door closes on its own when opened 45 degrees.
⚠️ Attention: If after turning on the refrigerator makes unusual sounds or does not cool for 5-6 hours, do not try to disassemble it yourself. Contact an authorized service center, as there may be a refrigerant leak or a breakdown of the start relay.
Diagnostics of problems after starting
After the refrigerator has worked several cycles, it is worth carrying out diagnostics. Check the temperature in the chambers using a thermometer. In the refrigerator compartment it should be within +2...+5°C, in the freezer - no higher than -18°C. If the temperature differs significantly, a thermostat adjustment or a leak test may be required.
Inspect the back wall inside the refrigerator compartment. In models with a drip system (“crying wall”), moisture should collect in a groove and leave, and not freeze as a crust of ice over the entire surface. The formation of ice on the back wall immediately after defrosting may indicate a malfunction of the defrost sensor or heating element, if we are talking about No Frost.
Also pay attention to vibration. Light vibration of the housing during compressor operation is acceptable, but it should not be transmitted to furniture or accompanied by rattling. If you notice strong vibrations, check to see if the condenser tubes are touching each other or the cabinet walls.
Is it possible to turn on the Indesit refrigerator immediately after defrosting if you used a hair dryer?
No, you cannot. Using a hair dryer speeds up the melting of the ice, but does not remove moisture from hard-to-reach places and does not allow the oil time to drain into the compressor. In this case, the risk of water hammer and short circuit is maximum. The minimum waiting time after using a hairdryer is 4-6 hours.
What to do if the refrigerator turns on, but does not freeze?
If more than 5-6 hours have passed after turning it on and the cold has not appeared, check if the compressor is working (it should hum and be warm at the back). If the compressor is running, but there is no cold, there is probably a freon leak. If the compressor is silent or clicking, there is a problem with the start relay or thermostat. A technician is required.
Do I need to wash the refrigerator before turning it on for the first time after purchase?
Yes, definitely. New refrigerators often have a plastic smell and factory dust. They need to be washed with warm water and a mild detergent, dried thoroughly and allowed to stand turned off for 2-4 hours before starting for the first time.
Does the time of year affect the duration of defrosting?
Yes, directly. In summer, ice melts faster, but moisture also evaporates more actively. In winter, especially in unheated rooms, the process may take longer, and the time for drying and acclimatization before turning on must be increased by 1.5-2 times.
Why does the refrigerator work louder than usual after defrosting?
In the first hours of operation after defrosting, the compressor may work more intensely to gain temperature. Also check that the refrigerator is level. If the noise does not subside after a day or is accompanied by knocking, this is a sign of a malfunction.
