Connecting IKEA Built-in Appliances: Perilex, Groups & Safety

An IKEA METOD kitchen is only complete when all appliances work. Whether you bought your built-in appliances from IKEA (often produced by Electrolux or Whirlpool) or opted for brands like Bosch or Siemens, connecting them safely and correctly is crucial.

Many people think connecting an oven or dishwasher is just plugging it in. But in a modern kitchen, this is absolutely not the case. In this article, we cover the most important points for safely connecting built-in appliances.

1. Separate Groups in the Meter Cupboard

Modern kitchen appliances use a lot of power. A golden rule in kitchen installation is: Appliances with a power consumption of more than 2000 Watt require their own, separate electrical group.

  • Oven / Combi Microwave: These almost always require their own group. If you connect an oven and a dishwasher to the same group and turn them both on, the fuses will immediately blow.
  • Dishwasher: Requires a separate group.
  • Quooker (Boiling water tap): Requires a separate group, or a 'power switch' (energy divider) if it has to share a group with the dishwasher.

[!WARNING] Ensure the electrical installation is completely finished and tested before the kitchen cabinets are placed. Once the cabinets and worktop are in place, adding a new pipe to the meter cupboard is almost impossible without demolition work.

2. Induction Cooktop: The Perilex Connection

Cooking on gas is increasingly a thing of the past; induction is the standard. An induction cooktop uses so much power (often between 7000 and 11000 Watts) that a normal plug (Schuko) will instantly melt.

For an induction cooktop, you need a Perilex connection. This is a large, square plug with four or five pins.

  • 2-Phase (Cooker group): Most standard IKEA induction cooktops (like the BEJUBLAD or MATMÄSSIG) work on a 2-phase connection. This requires a double group in your meter cupboard.
  • 3-Phase (Power current): For very wide or powerful cooktops (like those with integrated extraction), a 3-phase connection is sometimes required.

Important: Never just plug a Perilex plug into the wall socket. The wiring of the plug must correspond exactly to how the electrician has wired the wall socket. If this is connected incorrectly, the cooktop will immediately short-circuit and break down.

3. Water and Drainage (Dishwasher and Sink)

Connecting the dishwasher and the tap seems simple, but water damage is the biggest enemy of your new IKEA cabinets.

  • Dishwasher: Ensure the water supply has an accessible washing machine tap (aerator tap), so you can quickly turn off the water in an emergency. The drain hose of the dishwasher must be connected to the siphon of the sink.
  • Siphon: IKEA uses special space-saving siphons (LILLVIKEN). These run entirely against the back wall, so the drawers under the sink can close completely. Follow the manual exactly and ensure all rubber rings are in place to prevent leaks.

4. Ventilation for Fridge and Freezer

Built-in fridges and freezers produce heat at the back. If this heat cannot escape, the appliance will consume more energy and eventually break down.

  • IKEA tall cabinets for fridges have a ventilation grille in the plinth (at the bottom) and space at the top so the warm air can flow upwards (chimney effect).
  • Never block these ventilation openings! Do not store items on top of the cabinet that cover the ventilation gap.

Frequently Asked Questions (FAQ)

Which appliances need their own electrical group?

Appliances with a power consumption of more than 2000 Watt require their own, separate electrical group. This includes the oven, combi microwave, dishwasher, and Quooker. If you connect an oven and a dishwasher to the same group and turn them both on, the fuses will immediately blow.

What is a Perilex connection and when do I need it?

A Perilex connection is a large, square plug with four or five pins used for induction cooktops, which use between 7000 and 11000 Watts. Most standard IKEA induction cooktops work on a 2-phase connection (cooker group), while very wide or powerful cooktops sometimes require a 3-phase connection.

Can I just plug a Perilex plug into the wall socket?

No, never just plug a Perilex plug into the wall socket. The wiring of the plug must correspond exactly to how the electrician has wired the wall socket. If this is connected incorrectly, the cooktop will immediately short-circuit and break down.

Safe and Certified Assembly

Connecting heavy electrical appliances and water pipes brings risks. An incorrectly connected cooktop can cause a fire, and a leaking siphon will ruin your base cabinet.
