While not all of us may be handy around tools, not every home maintenance activity needs us to hire professional help. Some of these can be easily handled by novices as well, just as long as we have the right guidance and we follow instructions. If you’re a greenhorn handyman, a relatively simple DIY activity like removing an old dishwasher should be easy for you to handle by yourself. All you need to do is gather the basic tools needed, and follow these step-by-step instructions described below.

How to remove a dishwasher: Tools needed

Guide to home maintenance
  1. A piece of cardboard larger than the base of the dishwasher.
  2. Protective gloves.
  3. Voltage detector pen
  4. Crescent wrench
  5. Screwdriver
  6. An old towel

The process

Cutting the power

Safety is of paramount importance while working with any electrical appliance, and your dishwasher is no different. The first thing you will need to do is disconnect the power to the dishwasher.

In some cases, the dishwasher is connected to an outlet located right underneath the sink. If this is the case, all you need to do is switch off the outlet and unplug the appliance.

However, if it is connected wired directly to the home’s electrical system, you will need to locate the correct circuit breaker and switch it off

Stopping the water supply and removing the line

The water supply line that connects your home’s water supply to the dishwasher will be located underneath the sink and will be a metal supply line. Follow the line from the dishwasher to the supply line on the wall. All you will need to do is turn the shutoff valve clockwise until it is tight to Turn off the water supply.

The line is connected by a single metal nut. Use the crescent wrench to turn it clockwise to loosen and remove the nut. You’ve now removed the water supply line.

Removing the drain hose

Next, you will need to disconnect the drain line connecting the dishwasher to the sink drain. Use a screwdriver to disconnect the screws connecting this flexible hose to the garbage disposal. Once it is detached, pull it into the area below your sink. 

Some water may spill out of the drain hose. Use your old towel to mop up the water. 

Detaching from the kitchen countertop

The dishwasher is usually attached to the kitchen countertop using two screws on the underside of the countertop. Use a screwdriver to loosen and remove these screws from the attachment bracket.

Removing the panel

At the bottom of the dishwasher, you will find a panel that covers the underside, hiding the water supply, electrical supply, and drain. This is held in place by a few screws. 

To remove the panel, locate and unscrew these using your screwdriver. You can now remove and set aside the panel.

Disconnecting the water supply

Once the panel has been removed, you ought to see the power supply, which will be a white or a yellow cord, a metal or copper pipe for the water supply, and the drain.

A metal nut will be connecting the dishwasher to the water supply. 

Use a crescent wrench to loosen the nut until you can loosen it with your fingers. Continue to loosen it until it is completely disconnected. 

Expect some spillage if there is some residual water in the dishwasher. Use the old towel and mop it up.

Loosening the legs

Loosening the front legs of the dishwasher is easier than loosening the rear ones. Use the crescent wrench to turn the leg leveling screws anti-clockwise until you can turn them by hand. Loosen the front legs so you have around an inch of gap between the dishwasher and the floor. This will make it easy for you to tilt and maneuver the dishwasher out.

The rear legs are not so easy to loosen. Place the large piece of cardboard underneath the front legs, so you don’t scratch your kitchen floor. Next, slide the dishwasher as far out as you possibly can. Keep in mind that unless the dishwasher’s power outlet was underneath the kitchen sink, it is still connected to the power supply, so you will need to be careful. 

Once you’ve moved the dishwasher enough to give you access to the rear, use the crescent wrench and your fingers to loosen the rear legs as well.

Disconnecting the power supply

Use the voltage detector pen to check if the dishwasher still has power. If it does, it means you haven’t found the correct circuit breaker to switch off. Recheck your connections and switch off the correct breaker, making sure to turn off the power to the dishwasher.

Once that is done, locate the powerbox at the bottom of the dishwasher. Open it up by unscrewing the screws holding it in place. You will find a copper wire, a black wire, and a white wire. Unscrew the white and black wire nuts, and then unscrew the copper wire from the box. Replace the wire nuts.
