Question 1

What is the condenser on my HIGH ONE DC 7 B W566C dryer?

Accepted Answer

The thermal condenser is a key component of your HIGH ONE DC 7 B W566C dryer that transforms the water vapor generated during drying into liquid water through cooling. This condensation process captures moisture in the form of droplets that then flow into the removable tank located at the bottom of the appliance.

On your model, the condenser is located inside the appliance and can be accessed through the maintenance grille at the front (marked [9] in your documentation) after unlocking this hatch. It is accompanied by seals and locking levers that keep the system airtight.

Regular maintenance of the condenser: To maintain the efficiency of your dryer, the condenser should be cleaned approximately every 2 to 3 months if you use the appliance frequently. In case of less intensive use, you can space out these interventions.

Simple cleaning procedure (monthly): Remove lint from the thermal condenser with a sponge or a soft brush. This operation takes a few minutes and maintains good air circulation.
Complete cleaning (every 2-3 months): Allow the dryer to cool down, unscrew the maintenance hatch by unscrewing the two levers, pull the condenser towards you, clean it thoroughly with water only, let it drain, clean the seals, and then reinsert it in place.

A condenser clogged with lint significantly reduces the drainage of condensed water and causes longer drying cycles, increased energy consumption, and may stop the program if the water tank fills up. During complete cleaning, it is normal for residual water to flow out: place an absorbent cloth under the maintenance hatch.

Important points: Clean the condenser only with water, without using sharp-edged objects that could damage it. Never operate the appliance without its condenser in place. During drying cycles, it is normal for water to accumulate between the glass and the condenser seal; this does not affect the operation of your appliance.

Question 2

Why is my HIGH ONE DC 7 B W566C dryer not draining water anymore and how can I fix it?

Accepted Answer

If your HIGH ONE DC 7 B W566C dryer is not draining water anymore, several elements of the condensation circuit may be at fault. Here’s how to diagnose and resolve the issue:

Initial Checks

Check the tank: If it is full, it blocks the drainage of water to the pipes. Completely empty the removable tank located at the bottom of the appliance after each cycle.
Clean the condenser: A dirty condenser clogged with lint significantly reduces water drainage. Access the maintenance grille at the front (part [9]), unplug the appliance, then clean the condenser with a sponge or a soft brush after it has cooled down. This maintenance should be performed approximately every 3 months.
Clean the filter: The lint filter must be cleaned after each use to maintain good air circulation and proper drainage.

Checking the Drain Hose

Completely unplug the appliance.
Access the transparent (or semi-transparent) drain hose through the maintenance grille [9] at the front.
Check that the hose is not twisted, blocked by lint, or damaged (visible cracks).
Check the two connection points of the hose: at the outlet of the condenser and at the tank/external drainage.

If after these checks the water still does not drain normally, technical assistance may be necessary.

Question 3

What does the 3h light with the flashing padlock mean on my HIGH ONE DC 7 B W566C dryer?

Accepted Answer

The flashing padlock + 3h light indicates that the Child Safety function is activated on your dryer.

When this protection is active, only the On/Off button works - all other buttons are locked to prevent a child from accidentally starting a cycle. The visible 3h may correspond to a delay that was programmed before the lock was activated.

To deactivate this protection:

Press the Anti-Crease and Delayed Start buttons simultaneously
Hold them down for more than 3 seconds

The light should then turn off and you will regain normal access to all buttons.

Question 4

What are the consequences of the automatic setting on the HIGH ONE DC 7 B W566C dryer?

Accepted Answer

The automatic setting of the HIGH ONE DC 7 B W566C dryer works thanks to an automatic moisture sensor that precisely detects the moisture level of your clothes during drying. Once the laundry is sufficiently dry, the dryer stops automatically by adjusting the remaining time for each cycle, thus avoiding unnecessary drying beyond what is needed.

This function leads to a significant reduction in energy consumption. By stopping operation as soon as the moisture is at an acceptable level, you do not waste electricity on clothes that are already dry. This represents a notable saving on your energy bill, especially if you use the dryer regularly.

The automatic setting protects your textiles by limiting exposure to heat. Excessive prolonged drying can damage fibers, shrink certain garments, or make them too brittle. By automatically stopping the cycle at the optimal moment, the moisture sensor preserves the quality and durability of your clothes, especially delicate fabrics.

From a practical standpoint, you do not have to guess the drying time. Unlike manual programs where you have to set an approximate duration, the automatic system adapts to the actual weight of the laundry and its initial moisture level. This means a more reliable and uniform result with each use, without the risk of clothes being half dry or excessively dry.

It is important to note that the drum may stop briefly for about 40 seconds during drying: this is part of the normal operation of the moisture sensor that takes measurements. The operation indicator will continue to blink normally, and the dryer will adjust the remaining time before resuming its cycle.

Question 5

How to locate the drainage pipe to the water tank on the HIGH ONE DC 7 B W566C dryer in case of water leakage?

Accepted Answer

The HIGH ONE DC 7 B W566C dryer operates with a condensation system: during drying, humid air passes through a thermal condenser that transforms water vapor into liquid water. This water must then flow into the removable tank located at the bottom of the appliance or to an external drainage outlet if the optional pipe has been installed.

To locate and check the drainage pipe in case of a leak, start by completely unplugging the appliance from the electrical outlet. Gently move the dryer to access its lower part. You will find a maintenance grille at the front of the appliance (marked [9] in the documentation): unlock this hatch and open it fully to visualize the internal components, including the thermal condenser and the drainage pipe that comes out of it.

The drainage pipe is a plastic tube (usually clear or semi-transparent) that connects the thermal condenser to the water tank located at the bottom. You may also see the optional external drainage pipe (provided on some models) that allows water to be drained directly to a water point. Carefully check that this pipe does not have cracks, perforations, or twists that would prevent normal water flow.

Check the two connection points: one at the outlet of the condenser and the other above the tank or at the external drainage pipe. These connections must be firmly engaged. Sometimes, a simple reconnection is enough to stop a leak. Also, ensure that the pipe is not bent or blocked by lint that would reduce water flow.

If you notice that the tank overflows during the cycle, it means that it is full or that water is not accessing it properly due to the pipe. Once the problem is located, remember to completely drain the tank after each use to properly maintain your dryer and avoid water accumulation. If the leak persists despite these checks, contact ELECTRO DEPOT customer service.

Question 6

Why is the indicator light flashing on my HIGH ONE DC 7 B W566C dryer and the water tank is not filling up despite a complete cleaning?

Accepted Answer

If the indicator light is flashing and the tank is not filling up on your HIGH ONE DC 7 B W566C despite a complete cleaning, several elements of the condensation system may be at fault. Contrary to what it may seem, a flashing light does not always indicate that the tank is full: it may signal a failure of the water level sensor, the water pump, or the humidity sensor, which prevents the condensation water from accumulating properly.

Essential checks of the condensation system:

Completely clean the thermal condenser: this is the critical element. According to your manual, clean it every 2 to 3 months with a sponge or a soft brush. A buildup of lint blocks air circulation and condensation formation. Allow the appliance to cool down before any intervention.
Inspect the condensation drainage hose if it exists on your model: check that it is not bent, crushed, or blocked. Water should flow freely from the condenser to the tank.
Ensure that the water tank is properly clicked into place and that there are no cracks damaging it. Empty it completely, rinse it, and reinstall it firmly.

Sensor and water pump issues: The LED “Full” that lights up continuously or a light that flashes repeatedly may indicate a malfunction of the water level sensor or the water pump. In this case, no cleaning of the filters will solve the problem as the system is unable to detect or drain the water. The humidity sensor may also be dirty: gently clean it with a soft, damp cloth.

Another common cause: make sure that your lint filter is completely cleaned after each use and that the base of the filter (accessible via the maintenance grille) is clear. Accumulated lint prevents proper air circulation, slows down drying, and can affect condensation.

If after these checks the light continues to flash and the tank remains empty, unplug the appliance for a few minutes, then plug it back in to reset the electronic system. If the problem persists, it is likely a technical failure (faulty sensor, worn pump, or damaged hot water resistance) that requires the intervention of HIGH ONE / ELECTRO DEPOT customer service, as these components are not cleanable.
