<p class="info-desc">There is a little noise when the pump that drains the condensed water inside the dryer operates.</p>
<h3 class="sub-tit">The operation principle of a drain pump </h3>
<p>A heat pump dryer condenses the moisture in the laundry into water during the drying process, and automatically washes the condenser by pumping condensed water using a drain pump.</p>
<div class="tip-box">
<strong class="tip-tit">What is an automatic cleaning condenser?</strong>

<div class="con-view">
Unlike an existing heater dryer that requires periodic cleaning of its heat exchanger, the new heat pump dryer has an automatic cleaning function, and cleans away very fine dust which has escaped the lint filter and stuck to the heat exchanger.
</div>

<h3 class="sub-tit">A noise that occurs within 5 minutes of the start of operation (humming noise together with the sound of water)</h3>
<p>
At the start of operation, the drain pump operates within the first 5 minutes for 30 to 180 seconds, depending on the quantity of water to be removed.<br>
Rest assured, as the noise made at this time is the sound of the drain pump operating normally.
</p>
<h3 class="sub-tit">A noise that occurs during the drying cycle (humming noise together with the sound of water)</h3>
<p>
If the water level sensor in the machine detects the condensed water accumulated exceeds a specified level during operation of the dryer, the drain pump operates and water is drained for 30 to 180 seconds, depending on the quantity of water.<br>
Rest assured, as the noise made at this time is the sound of the drain pump operating normally.
