When your new washing machine, dishwasher or fridge-freezer arrives, it’s tempting to plug it in straight away and start using it. But before you press that start button, it’s worth taking a few minutes to make sure everything has been installed correctly. A small mistake or loose connection can quickly lead to leaks, poor performance or even electrical faults. Here’s a practical guide to checking your installation and spotting problems before they cause trouble.

Inspect the delivery

When your appliance is delivered, always check its condition before signing for it. Look for dents, scratches or damage to the packaging. If you notice anything, make a note on the delivery paperwork and take photos – this can be vital if you need to make a claim later.

Unpack the appliance carefully and check that all parts and accessories are included. Many models come with hoses, fittings, brackets or manuals that are essential for correct installation.

Check the surface and positioning

A stable, level surface is key to proper operation. A washing machine that isn’t level can vibrate excessively and make noise, while an uneven floor can affect how a fridge door seals.

Use a spirit level to ensure the appliance stands straight. Most appliances have adjustable feet so you can fine-tune the height. Make sure there’s enough space around it for ventilation and to prevent overheating – especially for fridges and tumble dryers.

Examine the connections – water, drainage and power

Most installation issues occur at the connection points, so go through them carefully:

• Water supply: Ensure the hose is properly fitted and not twisted or kinked. Check that washers are in place and that there are no drips when you turn on the tap.
• Drainage: The waste hose should be secured but not pushed too far into the drain, as this can cause backflow. Always follow the manufacturer’s instructions for height and placement.
• Power: Always use a properly earthed socket and avoid extension leads. If you’re unsure about your electrical setup, have a qualified electrician check it.

A quick inspection of these points can save you from water damage or electrical hazards later on.

Run a test cycle without a load

Before using the appliance for real, it’s a good idea to run a short test cycle with no laundry, dishes or food inside. This is especially important for washing machines and dishwashers. It allows you to spot leaks, unusual noises or error messages before everyday use.

Watch to see that water flows in and out correctly and that the appliance stays stable during operation. If you hear knocking, rattling or feel strong vibrations, it could mean transport bolts haven’t been removed or the machine isn’t level.

Review the controls and functions

Even a perfect installation can cause problems if the appliance is used incorrectly. Take time to read the user manual – particularly the sections on first use, maintenance and safety. Many modern appliances have sensors and smart features that need proper setup to work efficiently.

Check that the display, buttons and indicator lights respond as expected. If something doesn’t work, it could be a loose connection or a fault in the electronics.

Watch for early warning signs

Some issues only appear after a few days of use. Listen for unusual sounds, feel for heat around the plug, and check for moisture near hoses and joints. A small leak can quickly become a bigger problem if left unnoticed.

It’s also a good idea to note the installation date and take photos of the setup. This makes it easier to provide evidence if you need to contact the retailer or manufacturer later.

Get professional help if in doubt

While many appliances are designed for easy installation, there are times when it’s best to call in a professional. This is especially true if any permanent plumbing or electrical work is required. A qualified installer can ensure everything meets UK safety standards – and that your warranty remains valid.

A careful start for a longer life

Checking your installation thoroughly isn’t just about avoiding immediate faults. It’s also an investment in your appliance’s lifespan. A correctly installed machine uses less energy, experiences less wear and tear, and delivers better results day to day.

So take a few extra minutes to check everything before you press start. It’s a small effort that can make a big difference – for your safety, your peace of mind and your appliance’s performance.
