Wondering how to install a dishwasher? If you know what you’re doing, dishwasher installation is usually quite easy. But if this is your first time, it’s important that you read up thoroughly before you start.

You could begin by watching this YouTube video: Dishwasher Installation Help: How To Hook Up A Dishwasher. Although it is aimed at the American market, it does cover some dishwasher installation fundamentals – such as checking that the water and electricity supplies are switched off, and measuring your cavity to ensure the new model will fit.

Next, you could visit the the LG website and read their handy written guide: Dishwasher Installation Tips. This article answers the most commonly asked questions, such as “What is the water temperature requirement?” and “What type of tubing can be used for the water inlet hose?”

Appliances Online consulted Sydney plumbing specialist Ed Wharton (from Aquila Plumbing – ph: 0404 625 413), who gave us his guide: How To Install A Dishwasher – 10 Dishwasher Installation Tips:

1. Lay a drop sheet or coversheet in kitchen area where proposed working area will be.

2. Turn off the water to the dishwasher, and then disconnect the old dishwasher in cupboard. Undo cold water hose, electrical lead and unscrew clamp form waste pipe.

3. Sweep and clean proposed area for the new dishwasher.

4. Remove new dishwasher from packaging and check that there are no scratches or marks and that there is an owner’s manual and warranty.

5. Position the dishwasher close and begin to slide all three components through the cupboard – water, waste and electrical. As you slide the appliance back, pull the components through the cupboards allowing plenty of slack so they do not kink behind the cupboards.

6. Connect the cold water hose into the isolation valve where you removed the old one, tightening clockwise – hand tighten only.

7. Plug in the electrical lead and turn water and power back on.

8. Insert waste hose into the nip of the sink trap (outlet) making sure that the hose has been looped up in a upside down U shape and fastened as high as possible (this is to avoid syphonage) and clamp tightly with clamp provided.

9. Turn on dishwasher to full cycle and watch for any leaks – this will wash out any debris in the system.

10. Read operating manual for any tips on preserving your new investment.
