Compact placement of household appliances is a key trend in modern interiors, especially in limited space. Installation dryer on a washing machine in a column allows you to save up to 50% of space, but requires strict adherence to technical standards. Improper installation can lead to vibrations, equipment falling, or even a short circuit.

In this article we will analyze all the stages - from choosing compatible models to final fixation. You will find out what column fastenings suitable for your equipment, how to avoid common mistakes when docking and what brands (for example, Bosch, Samsung or Electrolux) offer ready-made solutions for vertical installation. We will pay special attention security: how to distribute the load so that the upper machine does not “walk” during the spin cycle, and what DIN standards regulate such structures.

1. Washer and dryer compatibility: what to check before purchasing

Not all models are suitable for column installation. The first thing you should pay attention to is dimensions. The width and depth of both machines must match to the nearest millimeter. Standard dimensions for column:

  • 📏 Width: 60 cm (European standard) or 55 cm (compact models)
  • 📐 Depth: 40–60 cm (depending on manufacturer)
  • ⚖️ Maximum load on top machine: usually 80–100 kg (check your passport)

Second - download type. Only suitable for columns front loading machines. The top dryer must have reversible door (opening left/right) so as not to block access to the washing machine. For example, at LG F4V9RWP2T the door is re-hung in 5 minutes, and Beko DPU 7305 X - only at the service center.

Critical moment: check vibration isolation washing machine. Models with direct drive (for example, LG TrueSteam) vibrate less than belt ones. If the top dryer weighs 30+ kg, the risk of shifting when spinning at 1200 rpm increases 3 times.

⚠️ Attention: Never install machines with different widths in a column. Even a 2 cm gap will lead to imbalance of the center of gravity and will increase the load on the fastenings by 40%.

2. Necessary components: what to buy besides the machines themselves

For reliable fixation you will need special accessories. Basic set:

Accessories Purpose Cost (average) Model example
Column mounting kit Docking the upper and lower machines 1 500–3 000 ₽ Bosch WZL 24640
Anti-vibration feet Damping vibrations during spinning 800–1 200 ₽ VibraStop VS-4
Drain hose extension If a standard hose does not reach the sewer 300–600 ₽ Electrolux E6SHG01
Safety bar between machines Prevents scratches and chips 500–900 ₽ Samsung WA-PAD

Please note fastening material. Cheap plastic kits can withstand up to 60 kg, and metal ones (for example, from Miele) - up to 120 kg. If the dryer weighs more than 35 kg, take only steel kits with rubber gaskets.

💡

Before purchasing mounts, measure the distance between the mounting holes on the back of the machines. U Bosch and Siemens it is standard - 540 mm, and Indesit may differ by 5–10 mm.

Additionally you may need:

  • 🔌 Extension cord with grounding (if the outlet is far away)
  • 🔧 Laser level (for precise horizontal installation)
  • 🛠️ Hex key 5 mm (for tightening fasteners)

3. Step-by-step installation instructions: from preparation to fixation

Before starting work, unplug both machines and turn off the water. The floor under the column should be perfectly level — the permissible difference is no more than 2 mm per 1 meter. If the floor is uneven, use adjustable legs or cement screed.

Make sure both machines are unplugged and unplugged|

Check the levelness of the floor using a building level|

Unpack and inspect the mounting kit for defects|

Prepare tools: screwdriver, wrench, level, tape measure -->

Step 1. Install the lower (washing) machine

Place the washing machine in place and adjust the legs so that it is level. You can check this with a level by placing it on top. If the machine wobbles, tighten the legs counterclockwise. Models Samsung WW90T554DAW the legs are secured with nuts - do not forget to tighten them.

Step 2. Mounting the mounting kit

Try the top bar of the kit on the washing machine. It is usually secured with 4 bolts from the back. Tighten the bolts in a cross pattern to avoid distortion. Tightening force: 8–10 Nm (use a torque wrench if available).

Step 3: Install the dryer

Carefully lift the dryer and place it on the rack. Most kits have guide grooves - the machine needs to be moved until it clicks. After this, secure it with bolts from below (usually 2-4 pieces).

Step 4. Connecting communications

Connect the dryer drain hose to a drain or trap. If you use a common drain with your washing machine, install tee with check valveto avoid overflow. The power supply for both machines must come from the same grounded outlet (minimum outlet capacity - 16A).

💡

Use only original fasteners from the equipment manufacturer. Universal kits (for example, from NoName) may not withstand vibration when spinning at high speeds.

4. Common mistakes and how to avoid them

Even experienced craftsmen sometimes make mistakes when installing a column. Here are the most critical ones:

  1. Ignoring weight restrictions. If the dryer weighs 40 kg, and the fastenings are designed for 30 kg, the risk of collapse increases 5 times. Always check the maximum load in the kit's data sheet.
  2. Uneven floor. A misalignment of just 3° increases spin vibration by 30%. Use a level and adjustable feet.
  3. No anti-vibration pads. Without them, the upper machine will “walk” during the spin cycle. Gaskets from polyurethane (for example, VibraStop) reduce vibration by 70%.
  4. Connection to one outlet without grounding. This violates the rules of the PUE (clause 7.1.48) and can lead to electric shock.

Another typical problem is door lock. If the dryer is installed too close to the washing machine, the bottom door may not open completely. The minimum gap between machines is 5 cm.

⚠️ Attention: If, after installation, the dryer vibrates when the washing machine is running, check the fastenings immediately. Vibration of more than 5 mm in amplitude can lead to the destruction of the kit’s plastic parts in 2–3 months.

5. Installation features for different brands

Manufacturers often use unique fastening systems. Let's consider the nuances for popular brands:

  • 🔹 Bosch and Siemens: Use the system Stacking Kit with metal guides. Mounts are included with some models (for example, Bosch WTW87560). Important: the bolts are tightened with a force of 10 Nm.
  • 🔹 LG: On models with Direct Drive (for example, LG F4V9RWP2T) vibration is minimal, but special rubber gaskets are required LG SPK-1.
  • 🔹 Samsung: Mounts Samsung SK-5M compatible only with series machines EcoBubble. Other models require an adapter.
  • 🔹 Electrolux: Use the system TwistFix — fastenings snap into place without tools, but can only withstand up to 70 kg.

U Miele and AEG all column machines are marked "Stackable" in the passport. If there is no such inscription, installation in a column is prohibited by the manufacturer (risk of loss of warranty).

What happens if you install incompatible machines in a column?

Manufacturers refuse warranty repairs if they fall or break due to improper installation. For example, Samsung records cases where vibration during spinning led to cracks in the dryer body. In addition, incompatible fasteners may deform the washing machine frame, resulting in water leakage or a short circuit.

6. Test check after installation

After installation, be sure to test:

  1. Stability check: Gently rock the top machine. If it moves more than 1 cm, tighten the fasteners.
  2. Vibration test: Run the wash with a spin speed of 1000 rpm. Place a glass of water on the dryer - if the water does not splash, the vibration is normal.
  3. Door check: Make sure both doors open 90° without obstruction.
  4. Drain control: Start draining both machines at the same time. If the water drains slowly, check the slope of the hoses (optimally 3–5 cm per 1 meter).

If the dryer makes strange sounds (creaks, knocks), most likely the fastenings are not tightened enough or gaskets are missing. Models Beko and Indesit The plastic case often creaks - in this case, silicone grease for the guides will help.

7. Alternative placement options: when the column is not suitable

If your machines are not compatible for column installation, consider alternatives:

  • 🔄 Side by Side: Suitable for narrow spaces. The downside is that it takes up more space in width.
  • 🪟 Built-in technology: The machines are installed under a countertop or in a cabinet. Requires special models with ventilation.
  • 🚪 In the closet or hallway: If the layout allows, you can move the dryer to another room.
  • 🔌 Wall mounting: Some dryer models (for example, Candy CS4 H7A2TE) can be hung on brackets.

For small bathrooms (less than 4 m²) it is optimal to use combined machines (wash + dry in one unit), for example, Bosch WVG30461. They are more expensive, but save up to 60% of space.

Frequently Asked Questions

Is it possible to install cars of different brands in a column?

Technically possible, but highly not recommended. Different manufacturers use different mounting and alignment systems. For example, fastenings Bosch not suitable for LG due to different mounting hole locations. In addition, the warranty on both machines will be voided.

Do both machines need to be grounded if they are in a column?

Yes, definitely. According to the PUE (clause 1.7.51), all household appliances with a power exceeding 1.3 kW must be grounded. In a column, the machines are connected by metal fasteners, which creates an additional risk of current leakage. Use a grounded outlet or 30 mA RCD.

How often should the fasteners be checked after installation?

Carry out the first check 2 weeks after installation - during this time the fastenings may become loose due to vibrations. Then inspect them every 3 months. Pay special attention to the rubber gaskets: if they are cracked, replace them (the cost of a set is about 500 ₽).

Is it possible to make fastenings for a column yourself from scrap materials?

Absolutely not. Homemade fastenings (for example, from corners or wooden blocks) do not withstand dynamic loads during spinning. According to statistics, 80% of column falls occur precisely because of handicraft fasteners. Use only certified kits from the manufacturer.

What should I do if the dryer vibrates when the washing machine is running?

First check:

  1. Are all fastening bolts tightened (tightening torque: 8–10 Nm).
  2. Are anti-vibration pads installed between machines?
  3. Is the washing machine level (the permissible slope is no more than 2°).

If the vibration remains, reduce the spin speed to 800 rpm or install additional counterweights on the upper machine.
