Frequently Asked Questions - GDDEKD9 DIMPLEX

How do I clean the filter on the Dimplex GDDEKD9?

To clean the filter, first unplug the dehumidifier. Remove the filter cover located on the back or side of the unit. Take out the washable pre-filter and rinse it under warm running water. Allow it to dry completely before reinstalling. Do not use harsh chemicals or put the filter in a dishwasher.

Why is my dehumidifier not collecting water?

Check if the humidity level is set above the current room humidity. Also ensure the room temperature is above 5°C. The air filter may be clogged, reducing airflow. Make sure the water tank is properly seated and not full. If using continuous drainage, check the hose for kinks.

Can I use an extension cord with this dehumidifier?

It is recommended to plug the dehumidifier directly into a grounded wall outlet. If you must use an extension cord, use a heavy-duty cord with a minimum of 14 AWG and a length no longer than 2 meters, and ensure it is rated for the power consumption of the unit (180W). Avoid using multiple devices on the same extension cord.

What does the 'Defrost' mode do?

The auto defrost function prevents ice buildup on the coils when operating at low temperatures. The dehumidifier will automatically cycle into defrost mode, which may pause dehumidification for a short time. This is normal and helps maintain efficiency.

How often should I clean the water tank?

Clean the water tank every two weeks with mild soap and water to prevent mold and bacteria growth. Rinse thoroughly and dry before reinserting. If you notice unpleasant odors, clean more frequently.

What is the recommended humidity level for a basement?

For basements, a humidity level between 40% and 50% is recommended to prevent mold and mildew while avoiding excessive dryness. Set the dehumidifier to around 50% initially and adjust as needed.

Can I leave the dehumidifier running unattended?

Yes, the Dimplex GDDEKD9 is designed for continuous operation. It has an auto shut-off when the tank is full or the target humidity is reached. Ensure the water tank is properly positioned and the dehumidifier is on a stable, level surface.

How do I enable continuous drainage?

Remove the water tank and locate the drain outlet at the back of the unit. Connect a garden hose (not included) to the outlet. Ensure the hose runs downward to a floor drain or sink. Replace the water tank. The dehumidifier will automatically drain continuously.

What does the 'Timer' function do?

The timer allows you to set the dehumidifier to turn off after a specified number of hours, from 1 to 24. This is useful for energy saving or when you want the unit to stop during certain periods. Press the timer button repeatedly to set the desired hours.

Why does the unit make a gurgling sound?

Gurgling sounds are normal and indicate that water is being collected and draining into the tank or through the continuous drain hose. If the sound becomes excessive, check if the unit is level or if there is an airlock in the drain hose. Ensure the hose is not kinked.

- POWER BUTTON: Press this button to start or turn off the machine.

• FAN SPEED BUTTON: There are 3 selections under this button:

- SLEEP (MUTE): the unit will run in low ventilation/low heat, thus, the unit is quieter. And, if the ambient humidity is less than set humidity, it will run with fan (ventilation) only, no heat. Note! In sleep mode, the humidity indicator in the front plate will not light up.

• NORMAL: the unit will run in Medium ventilation/HIGH Heat. And, if the ambient humidity is less than the set humidity, the unit will run in Medium fan speed only, no Heat.
• TURBO: the unit will run in HIGH ventilation/HIGH Heat. And, when the ambient humidity is less than the set humidity, the unit will run in HIGH fan speed only, no Heat.

• AUTO BUTTON: By pressing this button, the unit will work automatically as below:

• Ambient humidity ≥ 70% .... unit works in HIGH speed dehumidify.

• 70% >ambient humidity ≥ 55% .... unit works in LOW speed dehumidify

• Ambient humidity < 55% , .... unit stops for 30mins -> fan resumes to work, to detect the ambient humidity. If higher than 55% , the unit resumes to work.

• OPERATION MODES: As an additional safety procedure, the dehumidifier rests for at least 30 minutes every 8 hours of operation. Every 30 minutes of rest, the fan mode turns on to check the ambient humidity and if needed (depending on the set mode), the dehumidifier will resume operation.

• DRY CLOTHES (LAUNDRY) BUTTON: This mode is designed to really dry out a room to allow clothes to dry faster. The dehumidifier will work continuously at a target humidity level of 40% humidity / high fan/high heat. The DRY CLOTHES indicator will light up. The dehumidify will also rest every 8 hours of operation.

- Under this mode, the fan speed is always fixed at HIGH speed and is not adjustable.

- HUMIDITY BUTTON: Set the humidity level you need: CNT (continuous dehumidify), 40%, 50%, 60% or 70%. The set HUMIDIFY level will show on the LED display.

If the HUMIDITY button is not set, the unit will work in the default setting: 50% humidity / low fan / low heat.

- CONTINUOUS DEHUMIDIFY MODE: The dehumidifier rests for 30 minutes between every 8 hours of dehumidification (at the set humidity level).

- Continuous dehumidify mode + Ambient humidity less than 35%

The heater works for 15 minutes, then rests for a few minutes and repeats this cycle, unless the humidity level rises.

• Usage when ambient temperature is higher than 36°C

The heater stops, but the fan keeps running to check humidity, then follows the general logic of stopping for 30 minutes if the desired humidity is reached.

• Working with humidity setting: 40%, 50%, 60% or 70%

The dehumidifier rests for 30 minutes between every 8 hours of dehumidification (at the set humidity level).

TIMER BUTTON

1. IN OPERATION TIMER: while the dehumidifier is operating, press TIMER button to set the number of hours you want the dehumidifier to continue operation. While pressing the button, the LED display will show the number of hours you set (between 0 and 24 in a cycle). The TIMER Indicator will light up at the same time.

When the set time has been reached, the machine will turn off automatically.

1. DELAYED START TIMER: while the dehumidifier is turned off/in standby mode, press the TIMER button to select the number of hours you want the dehumidify to countdown until it turns on. For example, if you select the timer to '2', the unit will turn on automatically after 2 hours and enter into the last used mode.

- AIR CLEAN BUTTON: By pressing this button, the unit will work in FAN (ventilation) only, no heat. AIR CLEAN indicator light will turn on at the same time. The fan speed is adjustable in this mode.

- DISPLAY WINDOW

This can display the:

- room temperature (0\~50°C).

– room humidity (35\~95% humidity).

- set humidity, while pressing the HUMIDITY button.

- set time while pressing the TIMER. After 8 seconds, the display returns to room humidity.

• ON INDICATOR (heat operation indicator)

- lights up in GREEN as the heat element is working.

- lights up in RED and blinks if the unit is tipped over.

- WATER FULL INDICATOR: The light turns red and blinks when the water tank is full or if the tank is not in the correct position.

- HUMIDITY INDICATOR IN THE FRONT: This unit has a special HUMIDITY INDICATOR in the front, enabling the user to tell the ambient humidity level immediately. It will light up in 3 different colors:

DRAINAGE

While the water tank is full, the unit will stop working for self-protection. The water full indicator will blink in red and the unit will buzz a warning.

To empty the tank, please follow these steps:

1. Hold the unit with one hand to steady it.

2. Pull out the tank squarely from the unit.

3. Remove the cover of the tank and carry it by its handle to empty the water.

4. After the tank is emptied, replace the tank cover and reinsert the water tank to the dehumidifier. Make sure it is properly positioned, so the 'water full' indicator light goes out and your dehumidifier is operating as normal again.

2. Unplug the water plug.
3. Connect the drain hole with a water tube of inner diameter 11mm.

* Please note, the water tube is not supplied with the unit.

1. Pull out the water tank, plug the dropping gate inside the unit with the water plug taken from the continuous drain.

2. Return the water tank to the correct position.
