Defrosting the DEHR refrigerator: complete instructions from preparation to completion

Brand refrigerators DEHR (manufactured by Dongbu Daewoo Electronics) are known for their reliability and modern cooling systems, but even they require periodic defrosting. Unlike models with a system, classic refrigerators with a drip system or manual defrosting require regular removal of ice - otherwise the compressor wears out, and energy consumption increases by 20-30%. In this article, we will look at how to properly defrost a refrigerator No Frost, classic refrigerators DEHR with a drip system or manual defrosting, they need to regularly remove ice - otherwise the compressor wears out, and energy consumption increases by 20–30%. In this article we will look at how to properly defrost a refrigerator. DEHR without the risk of damaging the equipment, how long it takes and what mistakes 90% of users make.

The defrosting process seems simple, but there are nuances: from preparation (where to put the food, how to turn off the power) to finishing (how to wash the shelves, how to quickly return the temperature). It is especially important to consider a unique feature of DEHR refrigerators is the sensitivity of electronic modules to sudden temperature changes when defrosting with a hairdryer or hot water. We have collected proven methods that are suitable for all popular series: DEHR 3200, DEHR 5100, DEHR 6500 and others.

If your refrigerator DEHR is equipped with a system Frost Free (hybrid), defrosting is still needed - but less often (once every 6-12 months). For models with Full No Frost the procedure is simplified, but there are rules for caring for ventilation grilles. Below are step-by-step instructions for each type, a defrosting time table and answers to frequently asked questions.

1. How often do you need to defrost a DEHR refrigerator?

The frequency of defrosting depends on type of cooling system, operating conditions and model. The manufacturer DEHR recommends the following intervals:

• 🧊 Drip system (Direct Cool): once every 1–2 months with intensive use (ice thickness more than 5 mm).
• ❄️ Manual Defrost: once every 3-4 weeks, if ice forms quickly (typical for models DEHR 2000–3000).
• 🌀 Frost Free: once every 6-12 months (ice forms only in the freezer).
• ⚡ Full No Frost: defrosting is not required, but needed cleaning the ventilation grilles every six months.

Signs that defrosting is needed urgently:

• 🔊 The compressor runs non-stop for more than 20 minutes.
• ❄️ Ice more than 1 cm thick (increases energy consumption by 30%).
• 🥶 The temperature in the chamber is above +5°C despite the set +4°C.
• 💧 Water under the vegetable boxes (the drainage hole is clogged).

⚠️ Attention: If the refrigerator DEHR with the system No Frost starts to freeze, this is a sign of a malfunction (breakage of the heating element, sensor or seal). In this case, defrosting will not help, diagnostics are needed.

The rate of ice formation depends. from:

• 🌡️ Room temperatures (optimally +18...+25°C).
• 🚪 Frequency of door openings (each opening adds 5–10% moisture).
• 🍲 Type of food stored (hot dishes, liquids without lids accelerate icing).

2. Preparing for defrosting: 7 steps before shutting down

Improper preparation is the main cause of breakdowns after defrosting Follow this algorithm to avoid short circuits, food spoilage or damage to the seal:

1. Adjust the temperature for. 12 hours before defrosting: set +2°C in the refrigerator and -12°C in the freezer. This will slow down the melting of the ice and keep the food longer.
2. Prepare food containers: use thermal bags, bowls with cold water or wrap the food in foil/towels. Place meat and fish in separate bags to avoid cross-contamination.
3. Unplug the refrigerator from networksby unplugging the plug. Do not use the power button on the panel —this may interfere with the settings.
4. Remove all shelves, drawers and grillesWash them separately in warm water with soda (2 tablespoons per 1 liter).
5. Place a tray to collect water under the drainage hole (usually at the bottom of the back wall B). models DEHR 5000+ there is a special tray.
6. Open the doors wide and secure them (you can use a chair or rope).
7. Check the seal: if the rubber cracked or deformed, replacement may be necessary after defrosting.

To speed up the process, prepare:

• 🧽 Soft sponges and microfiber rags.
• 🧂 Baking soda or a special product for refrigerators (without chlorine!).
• 🧊 Hairdryer (only with a cold blow function!) or fan.
• 📦 A vacuum cleaner with a narrow nozzle for cleaning the drainage hole.

⚠️ Attention: If in your models DEHR is electronic display (for example, DEHR 6500 Inverter), do not direct the hair dryer jet at the panel - this may damage the touch buttons.

3. Defrosting methods: which one to choose for your DEHR model?

There are 4 main defrosting methods, but not all are suitable for refrigerators DEHR. The choice depends on type of cooling system, the presence of the function quick defrost and even the material of the internal walls (new models use an antibacterial coating that cannot be scratched).

Step-by-step instructions for natural thawing (recommended method):

1. After turning off the refrigerator, wait 30 minutes - this time is needed to equalize the temperature inside the chambers.
2. Remove large pieces of ice with a wooden spatula (not a knife!). In models DEHR with a system Total No Frost ice usually accumulates only in the drainage holes.
3. Wipe the walls with a dry cloth to remove condensation. Do not use abrasive products!
4. Drain the water from the pan in refrigerators DEHR with the function Auto Defrost part of the water evaporates itself.
5. After complete thawing, dry the chambers with a hairdryer (cold mode) or leave open for 1 hour.

How to speed up defrosting with a hairdryer:

• 🔥 Use minimum temperature and keep the hairdryer at a distance of 20–30 cm from the walls.
• 🌀 Direct the air flow from top to bottom, avoiding seals and plastic parts.
• ⏱️ Use a hairdryer for no longer than 10 minutes in a row, then take a break.

⚠️ Attention: In refrigerators DEHR s inverter compressor (series Inverter) you cannot use a hairdryer or hot water - this may damage the control system. For such models, only natural thawing is suitable.

4. Cleaning after defrosting: what to wash and what not to do

After removing the ice, the refrigerator DEHR you need to not only wash it, but also disinfect it. Using unsuitable products may damage the antibacterial coating or leave a persistent odor. Here's what the manufacturer recommends:

• 🧼 For washing walls and shelves: a solution of baking soda (2 tbsp per 1 liter of water) or a special product for refrigerators (for example, Top House, Cillit Bang).
• 🧽 For sealant: soap solution (laundry soap) + toothbrush for hard-to-reach areas places.
• 🚫 Prohibited: chlorine-containing products, vinegar, acetone, metal sponges.
• 💨 For drying: soft rag or paper towels In models. DEHR 6000+ there is a function Air Dry —turn it on for 30 minutes.

Step-by-step cleaning:

1. Remove all removable elements (shelves, drawers, grilles) and wash them separately in warm water. For stubborn stains, use lemon juice + soda (paste).
2. Wipe the walls of the chambers with a soda solution, paying attention to the corners and drainage hole In models DEHR with system Multi Air Flow Clean the ventilation grilles with a cotton swab.
3. Wash the rubber seal with soapy water and lubricate it with silicone grease (sold in car dealerships) - this will extend its service life.
4. Clean the drainage hole (at the bottom of the rear wall) with a cotton swab sticks or vacuum cleaner. A clogged hole causes water to accumulate under the drawers.
5. Wipe the external surfaces with a damp cloth with a drop of glass cleaner (no ammonia!).

Disinfection (every 3-6 months):

• 🦠 Use a solution 1 tbsp hydrogen peroxide per 1 liter of water or a special antibacterial spray.
• 🍋 To remove odors, place lemon slices or activated carbon in the chambers for 12 hours.
• 🌿 models DEHR with the function Bio Shield disinfection is required less often - washing with soda is enough.

⚠️ Attention: If after cleaning the smell of detergent remains in the refrigerator, wipe the walls with clean water and leave the doors open for 2-3 hours In models. data-i="209">there is a function DEHR 5100+ there is a function Odor Filter —turn it on for a day.

What is the danger of cleaning with vinegar?

Vinegar corrodes the antibacterial coating of the internal walls of DEHR refrigerators, and its vapors can damage plastic parts. In addition, the smell of vinegar is absorbed into the seal and takes a long time. does not erode.

5. Completing defrosting: how to properly turn on the DEHR refrigerator

After cleaning, many users make a critical mistake - they immediately load the food and turn on the refrigerator. This leads to overload of the compressor and the risk of a short circuit. Follow this algorithm:

1. Dry the cameras within 1-2 hours. In models with the function Auto Dry 30 minutes are enough.
2. Install shelves and drawers in place. Check that they are level - distortions interfere with air circulation.
3. Connect the refrigerator to the network and turn it on empty. Let it run for 30-60 minutes so that the temperature stabilizes.
4. Adjust the temperature:
   • Refrigerator compartment: +4°C (optimal for storing most products).
   • Freezer compartment: -18°C (for long-term storage).
5. Load products gradually:
   • Place the most heat-intensive ones first (meat, semi-finished products).
   • After 1-2 hours, add dairy products, vegetables, fruits.
   • Load drinks and ready-made dishes last.

Features for models with an inverter compressor (DEHR Inverter):

• ⚡ After switching on, do not change the temperature for 6 hours - the compressor must adapt.
• 📉 Use the Ecomode, if available - this will reduce energy consumption by 10-15%.
• 🔇 In the first day after After defrosting, the refrigerator may operate louder than usual - this is normal.

Checking functionality:

• 🌡️ 2 hours after turning on, check the temperature with a thermometer (should be close to the set temperature).
• 💧 Make sure there are no puddles under the refrigerator (if there are, check the drainage hole).
• 🔊 Listen to the compressor: it should work in cycles (turn on/off), and not constantly.

⚠️ Attention: If after defrosting the refrigerator DEHR does not turn on or an error appears on the display (for example, E1, E2), do not try to repair it yourself. Disconnect from the network and call a technician - this may be a fault with the control board or compressor.

6. Typical mistakes when defrosting DEHR and how to avoid them

Even experienced users sometimes make mistakes that lead to breakdowns or shortening the life of the refrigerator. Here are the most common ones and ways to prevent them:

Error	Consequences	How. avoid
Using a knife to chip ice	Damage to the evaporator, leakage of freon	Use a plastic or wooden spatula
Defrosting with hot water (>60°C)	Deformation of plastic, cracks in glass shelves	Maximum water temperature - 40°C
Leaving water in the tray	Bacterial growth, unpleasant odor	Drain the water every 2 hours and wipe the tray
Switching on the refrigerator with wet walls	Short circuit, corrosion of metal parts	Dry the chambers with a hairdryer (cold mode) or a rag
Ignoring cleaning the drain holes	Accumulation of water under the drawers, mold	Clean the hole with a cotton swab once every 3 months

Other common mistakes:

• 🔌 Pulling a plug with wet hands —risk of electric shock Always dry your hands before turning off.
• ❄️ Defrosting at high humidity in the room (for example, in the bathroom). This prolongs the process and promotes the formation of condensation.
• 🧴 Use alcohol-based flavorings to remove odors - they can damage the plastic.
• ⏳ Interruption of defrosting (for example, if the ice has not completely melted). This leads to reverse freezing.

What to do if...

• 🔥 The refrigerator does not cool after defrosting: check if the drainage hole is clogged. If this is not the problem, it is possible. freon leak.
• 💦 Water continues to drip after turning on: this is normal for the first 2-3 hours. If longer, check the level of the refrigerator (it should be level).
• 🔊 A new noise has appeared: the tubes or the fan may have moved (in models with No Frost). Turn off the refrigerator and check the fastenings.

7. How to extend the time between defrosts?

Following simple operating rules will allow you to defrost the refrigerator DEHR less often - up to once every 3-6 months instead of a monthly procedure. This is what service center engineers recommend:

• 🌡️ Control the temperature:
  • Refrigerator: +4…+5°C (not lower, otherwise more ice will form).
  • Freezer compartment: -18°C (with -24°C ice forms faster).
• 🚪 Reduce door open time:
  • Plan what you will take before opening.
  • Do not leave the door open for more than 30 seconds.
• 🍲 Store food correctly:
  • Cool hot dishes to room temperature before serving.
  • Store liquids (soups, milk) in closed containers.
  • Do not place containers without lids in the refrigerator (evaporating moisture settles on the walls).
• 🧊 Use moisture absorbers:
  • Silica gel bags (place on the top shelf).
  • Special containers with absorbent (for example, Fridgemate).
• 🔄 Regularly clean the ventilation grilles (in models with No Frost) a vacuum cleaner or with a brush. Clogged grilles impair air circulation and lead to freezing.

For models with the system No Frost:

• 🌀 Once every 6 months, clean the fan from dust (it is located behind the back wall of the freezer). camera).
• 🔄 Check the operation of the defrosting heating element: if it does not turn on, ice will build up even in No Frostmodels.

For models with a drip system:

• 💧 Wash the drainage hole once a month soda solution (using a syringe without a needle).
• 🌡️ Make sure that the back wall of the refrigerator compartment is not covered with ice thicker than 3–5 mm.

⚠️ Attention: If your refrigerator DEHR starts to freeze up more often than usual, check:

• 🔌 Mains voltage (should be 220–230 V).
• 🚪 The tightness of the seal (a problem if the paper sheet is easily pulled out from under the closed door).
• 🌡️ Thermostat operation (if there is a malfunction, the compressor works without stopping).

These problems require professional repair.
