10 steps to plumbing in a washing machine
14 November 2022
1. Switch off and unplug your old washing machine
Before disconnecting your washing machine, remember to empty it of any clothes that may be in the drum and turn it off at the mains before unplugging it.
2. Switch off the cold water supply isolating valve
Pull your washing machine away from the wall and switch off the isolating valve in the cold water supply, this is typically a small blue tap.
3. Unscrew the cold water-in pipe
Your machine’s cold water supply is connected to your mains water through a hose that is attached to the top section of the back of your appliance.
Check that your cold water supply is switched off and unscrew the cold water in-pipe. Make sure you’ve got a bucket or tray handy to catch any water from the disconnected hose. Water from the cold water supply will now be turned off, so there should only be drips coming through.
4. Pull out the waste water hose
You should also see your water waste hose, a pipe that’s going from your washing into your kitchen floor. To disconnect the hose, you simply need to pull it out from your appliance.
Now that you’ve disconnected your washing machine from the cold water supply, electricity supply and water waste hose, you’re ready to remove your old machine with your new machine.
5. Remove carriage bolts from your new washing machine
The carriage bolts are attached to the back of washing machine. These will need to be removed before you install and start using it. The bolts are designed to keep the drum from moving around and potentially getting damaged while the machine is moving.
The bolts are screws that are attached to plugs. While they’re in place, press against the drum to secure it. There will typically be four bolts and all of them will need to be removed.
6. Attach the cold water-in hose
The hose you’ll need to install in your new washing machine is typically found inside the drum of the new washing machine, so open the door to find the parts you’ll need.
Screw the cold water in-pipe to the attachment at the top of the rear of the machine. As you do this, you’ll see a filter inside the attachment. Bear this filter in mind as something to check should your machine ever fail in the future. This filter can be unscrewed and washed under a tap.
The other end of the water in hose attaches to your cold water supply, this can be screwed into place.
7. Turn on water-in isolating valve
Once the cold water supply hose has been attached, release the isolating valve to allow water to flow through the pipe. Once the water has been released, check whether everything has been sufficiently fastened by looking for any leaks.
8. Attach waste water hose
The waste water hose will come already attached to your washing machine. It will just need to be manually fed into the waste water down pipe.
In many cases, your machine will come with a plastic U-bend that you can attach to the hose too. Rigid U-bends like this are handy because they help maintain the shape of the hose while avoiding blockages. You can attach the U-bend to the wall but keep this in mind when you pull the machine out in future.
Now push the washing machine back in place.
9. Level your washing machine
Finally, you’ll need to ensure that your washing machine is level before you begin using it. This is important to ensure the machine can spin comfortably without causing unwanted vibrations, noise, and damage.
Once your machine is in its final position, use a spirit level to confirm it’s level. If you don’t have one to hand, hold the machine in both corners and try to rock it back and forth gently. If it moves or the spirit level shows it isn’t level, you’ll need to adjust the legs at the front to make it secure. You might be able to do part of this job by hand but keep a spanner to hand.
You’ll need to loosen the locking nut, which locks the legs in position. Once loosened use a spanner on the legs to raise or lower the machine. Check your machine is level once again, then tighten the locking nuts again.
10. Your washing machine is ready to go
With the machine unpacked, the carriage bolts removed, water-in and waste water supplied, and the machine nicely levelled, your machine is now ready to use.
Fitting a washing machine can seem like a daunting prospect, but with these simple steps, you can fit it yourself with little fuss.
