Q: What fluid does the EXP34U338CW air conditioner use to operate?

The EXP34U338CW air conditioner uses R290 refrigerant to ensure its cooling. This is an environmentally friendly refrigerant that complies with European environmental directives. R290 is a flammable gas, which is why it is important to follow safety instructions: do not puncture or burn the device, and install it in a well-ventilated room of at least 12 m². In addition to this refrigerant, the unit produces condensate water during operation, particularly in cooling and dehumidification modes. This water accumulates in an internal tank that must be regularly emptied to avoid overflow or poor performance. To drain the condensate water: Make sure to regularly empty the tank, especially before storing the device for an extended period Use the provided drainage hose (adapters included) to direct the water to a collection point Ensure that the drainage hose is not bent or blocked for optimal flow Do not leave the hose elevated during dehumidification mode, otherwise, water may accumulate inside and escape into the room Do not confuse the refrigerant (which remains circulating in the device) with the condensate water (which needs to be drained). Proper maintenance of the drainage ensures the proper functioning and longevity of your air conditioner.

Q: How to clean the fan and filters of the WP71-265WT air conditioner?

Cleaning the filters: Always unplug the device before cleaning to avoid the risk of electric shock and fire Locate the filter tab at the back of the unit and gently remove the 4 filters one by one Clean the filters with hot water and a mild dishwashing detergent, rinsing thoroughly until all soap is removed Alternative: you can also vacuum the filters to clean them without wetting Gently shake off excess water from the filters and let them air dry completely before reinstalling Never install wet filters - complete drying is essential Important: the device should never operate without a filter, as this may damage it Cleaning the casing and front: Unplug the air conditioner before cleaning Dust the casing with an oil-free cloth to remove dust For wet cleaning, dampen a cloth with hot water and a mild dishwashing detergent, then wipe the casing and front of the device Rinse with a damp cloth of clear water and wipe completely with a dry cloth Pay special attention around buttons and controls: wring out the cloth well before cleaning them, as excess water could damage the device Never spray water directly on the device - risk of damaging the electrical insulation Never use aggressive products, wax, or polish on the casing Recommended frequency: Clean the filters of the WP71-265WT once every two weeks to maintain optimal filtration and efficient operation. More frequent cleaning may be necessary in very dusty environments.

Question 1

Why does my air conditioner EXP34U338CW stop after a few minutes of cooling, making a strange noise while only the fan continues to run?

Accepted Answer

This behavior generally indicates a safety shutdown of the compressor. Here are the most likely causes:

1. Clogged filters

This is the most common cause. Dirty filters reduce airflow and cause ice buildup on the internal evaporator. The unit stops to protect itself.

Clean the lower and upper filters with lukewarm water (less than 40°C) and a mild detergent
Let them dry completely before reinstalling
Repeat this cleaning every two weeks to avoid this problem

2. Insufficient ventilation of the unit

The EXP34U338CW air conditioner needs free space around it to operate properly.

Check that the drain hose is not blocked or bent
Ensure that the unit is not against a wall or in a corner
Keep at least 30 cm of free space around the unit

3. Noise and compressor shutdown

The strange noise you hear likely indicates that the compressor is shutting down (thermal protection activated). The fan continues alone, which is normal.

4. Check the set temperature

If the room quickly reaches the set temperature, the unit stops the compressor and switches to fan mode (fan only). This is normal operation in Auto mode.

Quick solution: clean the filters first, then test with the drain hose properly installed and the unit in a clear space. If the problem persists, there may be an issue with the R290 fluid charge - then contact a technician.

Cleaning the filters:

Always unplug the device before cleaning to avoid the risk of electric shock and fire
Locate the filter tab at the back of the unit and gently remove the 4 filters one by one
Clean the filters with hot water and a mild dishwashing detergent, rinsing thoroughly until all soap is removed
Alternative: you can also vacuum the filters to clean them without wetting
Gently shake off excess water from the filters and let them air dry completely before reinstalling
Never install wet filters - complete drying is essential
Important: the device should never operate without a filter, as this may damage it

Cleaning the casing and front:

Unplug the air conditioner before cleaning
Dust the casing with an oil-free cloth to remove dust
For wet cleaning, dampen a cloth with hot water and a mild dishwashing detergent, then wipe the casing and front of the device
Rinse with a damp cloth of clear water and wipe completely with a dry cloth
Pay special attention around buttons and controls: wring out the cloth well before cleaning them, as excess water could damage the device
Never spray water directly on the device - risk of damaging the electrical insulation
Never use aggressive products, wax, or polish on the casing

Recommended frequency: Clean the filters of the WP71-265WT once every two weeks to maintain optimal filtration and efficient operation. More frequent cleaning may be necessary in very dusty environments.

Question 4

How to disassemble and clean the lower filter of the air conditioner EXP34U338CW?

Accepted Answer

The lower filter of the ELECTROLUX EXP34U338CW air conditioner is easy to access and clean. Here’s how to proceed:

Disassembly Steps

Turn off the device and unplug it completely.
Locate the lower grille at the front of the unit.
Release the latches or hooks that hold the filter grille (usually located at the corners).
Pull the grille towards you to remove it completely.
The washable filter then easily detaches from the holder.

Cleaning and Reassembly

According to the product manual, clean the filters every two weeks for optimal efficiency. Rinse the filter under lukewarm water with a little mild soap, let it dry completely, then reinstall it in the reverse order. A dirty filter indicator activates after 250 hours of operation and prompts you to clean it.
