Question 5

How to check if the water connection is installed on the HAIER HSR3918FIPW refrigerator?

Accepted Answer

To check if the water connection is properly installed on your HAIER HSR3918FIPW refrigerator, follow these simple steps:

1. Visual inspection at the back of the appliance

Gently move the refrigerator to access the back.
Look for a hose connected to a valve; this indicates that the connection is made.
If you see a cap or cover on the valve without a hose, the connection has not yet been made.

2. Testing the water dispenser

Place a glass under the water dispenser located on the refrigerator door.
Press the "Water" button or push the lever of the dispenser.
If water flows, the connection is active.
If no water comes out, the connection is not in place or there is a problem.

3. Checking the shut-off valve

Locate the shut-off valve between your water tap and the refrigerator (often under the sink).
Make sure it is open to allow water to flow.

If the connection is not made, it is recommended to call a qualified professional for installation to ensure the correct and safe operation of your appliance.

Question 6

Do I need to manually fill the water reservoir of the HAIER HSR3918FIPW refrigerator and how do I proceed?

Accepted Answer

The HAIER HSR3918FIPW refrigerator does not need to be filled manually. This appliance has an automated water system that fills automatically once the refrigerator is connected to your household drinking water supply. The built-in ice and chilled water dispensers only work if this connection is established.

The connection must be made at installation by a qualified professional. The appliance connects directly to your drinking water network via a specialized pipe provided. Ensure that the water pressure is between 0.15 and 0.6 MPa for the system to function properly. The connection pipe should not exceed 8 meters in length.

The water system includes a water filter that purifies the water before distribution. This filter should be replaced approximately every 6 months to maintain the quality of the water and ice. Clean the internal reservoir if it has not been used for 48 hours. If you do not use the dispensers for more than 5 days, completely drain the water circuit by drawing water until none comes out.

A shut-off valve should be installed on the water supply line to allow for quick shut-off if needed. Before using the dispensers for the first time after installation, let water run for about 10 minutes to purge the circuit.

If you wish to clean the water system or have specific questions about the connection, refer to the detailed installation manual or contact HAIER customer service. Do not attempt to modify the water system yourself.

Question 7

How to get cold water with the Haier HSR3918FIPW refrigerator?

Accepted Answer

The Haier HSR3918FIPW refrigerator is equipped with a cold water dispenser located on the front door. To get cold water, follow these simple steps:

Activate the water function by pressing the "Water" button on the control panel. The corresponding light will turn on, indicating that the function is activated.
Place a glass under the water dispenser located on the front door of the appliance. Make sure the glass is properly aligned with the dispenser to avoid splashes.
Gently push the glass against the dispenser lever to trigger the flow of cold water into the glass.

For first use or after a long pause, it is mandatory to hold the lever down for 3 minutes to expel the air present in the piping. Additionally, the first 7 glasses of water should not be consumed as they contain the priming water of the system. Note that the first glasses may be slightly warmer than the subsequent ones – this is normal.

Before using the dispenser, ensure that the water line is properly connected to the refrigerator and that the water supply valve is fully open. The cold water pressure should be between 0.15 and 0.6 MPa for optimal operation. If the pressure exceeds 0.6 MPa, install a pressure reducer to avoid damaging the appliance.

Also remember to regularly empty the water collection tray located under the dispenser to prevent overflow when opening or closing the door.

The temperature display will start to blink, indicating that you are in setting mode.
Continue to press the " - " button until you reach the desired temperature.
The adjustable temperature range is between 5°C and 20°C.
Once the desired temperature is displayed, stop pressing the button: the selection will be confirmed automatically after about 3 seconds.

Temperature tips according to wine type:

Long-term storage: 10°C to 12°C
White wine: 9°C to 12°C
Red wine: 13°C to 20°C
Sparkling wine: 5°C to 8°C

Since your cellar currently displays 22°C, which is above the recommended range, it is advisable to reduce the temperature to around 12°C for proper storage, or even between 10°C and 11°C if you wish to store your wines for a long period.

Question 10

Why are the foods in my HAIER HDW3618DNPB refrigerator freezing at 5 degrees Celsius?

Accepted Answer

If the foods in your HAIER HDW3618DNPB are freezing while the thermostat shows 5 °C, it generally indicates that the actual temperature is lower than the displayed setting, or that the cold air is poorly distributed within the appliance. Although 5 °C is close to the recommended temperature (4 °C in normal mode), several factors can explain this freezing issue.

Start by checking and adjusting the temperature. For a HAIER refrigerator, the optimal range is between 3 °C and 5 °C. If you are in Eco mode (which automatically sets to 5 °C), try switching to 4 °C or 5 °C in manual mode. In summer, with a high ambient temperature, you can increase it to 6-8 °C. In winter, a setting of 3-4 °C is sufficient. Adjust gradually and wait 24 hours for the temperature to stabilize before fully loading the refrigerator.

Next, check the cold air circulation. The HDW3618DNPB model operates with a static cooling system, which distributes cold air unevenly. To optimize it, ensure that you do not block the cold air outlets (usually at the top or on the walls of the refrigerator), do not overfill the appliance, and leave enough space between foods to allow for air circulation. Also, avoid placing foods directly against the side or back walls, especially sensitive products (soft cheeses, creams, delicate vegetables), which freeze more quickly in the coldest spots.

For a static cooling system like yours, regular cleaning and defrosting are essential. Ice buildup on the walls and air outlets reduces cooling efficiency and creates overly cold zones. The manual recommends regular manual defrosting (at least once or twice a month depending on humidity). To defrost: turn off the appliance, open the door, and let the ice melt naturally. You can place absorbent towels on the floor to catch the water.

Then inspect the door seals. Worn or improperly positioned seals allow warm air to enter, forcing the refrigerator to compensate by cooling more, creating areas of over-freezing. Check that the seals adhere well along their entire length by closing the door on a sheet of paper: if the sheet slides easily, the seal needs to be cleaned or replaced.

If the problem persists after these checks (temperature increase, frost cleaning, seal inspection), contact an authorized Haier technician. Your refrigerator comes with a 2-year warranty, and a defective thermostat, improperly calibrated temperature sensor, or faulty fan (if present) require professional intervention for diagnosis and repair.
