Prepare the washer: turn off the water supply, unplug, and disconnect hoses

Before replacing a washer drain pan, it is important to prepare the washer. Start by turning off the water supply. Locate the water hose and turn it off. Next, unplug the washer from the wall. This is an essential step to ensure that you can safely work on the washer without any power still running through it. Once the washer is unplugged, you can then disconnect the water hoses. Place a bucket underneath to catch any residual water left in the hoses. It is also a good idea to have a towel ready to soak up any spillages.

At this stage, the washer should now be safe to work on, with no power or water supply connected. You can now begin the process of replacing the washer drain pan. This may involve lifting the washer and moving it away from the wall, which should be done with assistance due to the weight of the machine.

It is important to take safety precautions when working with appliances such as washers. Always ensure the power and water supply are turned off before beginning any work. Avoid attempting to lift and move the washer alone, as this could result in injury or damage to the appliance.

By following these steps, you can effectively prepare the washer for the replacement of the drain pan, ensuring a safe and efficient process.

Lift the washer and move it away from the drain pan

Lifting a washer and moving it away from the drain pan is a crucial step in replacing or installing a new drain pan. This process requires careful planning and execution to ensure safety and avoid damage to the washer or the surrounding area. Here are some detailed instructions to guide you through this task:

Prepare the Washer:

Before attempting to lift the washer, it's important to disconnect it from the power source and any water supply hoses. Turn off the water supply valves and unplug the machine. Additionally, it's advisable to tape any loose cords to the back of the washer to keep them tidy and out of the way.

Gather Assistance:

Washing machines can be heavy, with an average weight of 180 lbs., and larger machines can weigh upwards of 200 lbs. Therefore, it's crucial to enlist the help of at least one other person to lift and move the washer safely. Two people on either side of the washer can lift it together, and a third person can assist with guiding and stabilising the machine.

Protect the Washer and Surroundings:

To prevent scratches or dents on the washer and surrounding walls or floors, use furniture blankets or padding where applicable. This is especially important when sliding or repositioning the washer, as it can easily come into contact with surrounding surfaces. Additionally, always lift with your legs, not your back, to reduce the risk of injury.

Lift and Move the Washer:

Now, you can begin the process of lifting and moving the washer. Using the assistance of your helpers, lift the washer straight up and move it away from the drain pan, setting it down in a safe and secure location. Ensure that the washer is stable and won't topple over during this process. If you're working in a tight space, you may need to tilt the washer slightly to manoeuvre it out of the area.

Final Adjustments:

Once the washer is clear of the drain pan, make any necessary adjustments to the drain pan itself. This may include unscrewing the drain fitting, measuring the size of the hole, and drilling a new hole in the replacement drain pan if needed. Ensure that the new pan is properly positioned and secured before carefully lowering the washer back into place.

By following these steps and working carefully, you can successfully lift the washer and move it away from the drain pan, allowing you to proceed with the rest of the replacement or installation process. Remember always to prioritise safety and ask for help if needed.

Remove the old drain pan

Before removing the old drain pan, you must first disconnect the washing machine. Turn off the water supply and unplug the machine from the wall. Disconnect the water hoses and have a bucket and towel ready to collect any residual water left in the hoses.

Now, you can begin to remove the old drain pan. Using an assistant, lift the washer straight up and move it away from the drain pan. Set it down and lift the washer drain line from the fixture on the wall. Next, unscrew the drain fitting from the inside of the drain pan. This could be on the bottom or on the side. Use an adjustable pipe wrench to loosen the nut, washers and rubber grommet, and remove them.

With the washers, grommet and nut removed, you can now lift the drain pan out. You will then need to measure the size of the hole in the drain pan. Using a cordless drill and a drill bit or hole saw of the same size as the hole, drill a new hole in the same location as the old one.

It is important to take safety precautions when removing the old drain pan. Avoid lifting and moving the washing machine by yourself to avoid injury or dropping the appliance.

Install the new drain pan

Installing a new washer drain pan is a relatively straightforward process, but it requires careful planning and execution to ensure a proper seal and avoid leaks. Here is a step-by-step guide to installing a new washer drain pan:

Prepare the Area

Before installing the new drain pan, it is essential to prepare the area. If there is an existing washer, it must be turned off, unplugged, and disconnected from the water supply. Place a bucket and towel underneath to catch any residual water from the hoses. Use a dolly or hand truck to lift and move the washer away from the wall, providing access to the floor drain. Ensure you have the necessary tools and materials, including a measuring tape, pipe wrench, hose clamp, PVC pipe, and possibly some plumber's putty.

  • Positioning the Drain Pan: Place the new drain pan in the desired location, ensuring it is positioned correctly relative to the washer and the wall. The pan should be installed on a flat surface, and the lip of the pan should be higher than the ending (with fittings) top of the drain pipe to facilitate proper drainage.
  • Drilling the Hole: Mark the location of the drain pipe on the drain pan and drill a hole using a cordless drill and a drill bit or hole saw of the appropriate size. This step ensures that the drain pipe fits snugly through the pan.
  • Securing the Drain Pipe: Feed the drain pan's drain hose through the drain pipe. If the provided PVC fitting is not the right size, you may need to adjust it with a hacksaw or use a different fitting. Ensure the fitting penetrates through the hole you drilled, and secure it in place.
  • Sealing the Drain Pan: To create a watertight seal, you can use a silicone gasket, caulking, or plumber's putty. Apply the sealant around the underside of the drain lip and tighten it down. You can also use construction adhesive to secure the pan to the floor, preventing movement that could weaken the seal.
  • Adjustments: Adjust the drain pan as needed to ensure a proper fit with the drain pipe. The pan should be level and stable, allowing for efficient water removal.

Reinstall the Washer

Once the new drain pan is securely in place and any sealants have dried, you can reinstall the washer. Lift the washer and place it into the pan. Reconnect the hot and cold water lines, ensuring they are secure using a wrench. Place the drain line back into the receptacle, plug in the washer, and turn the power back on. After the first few washes, check for any signs of leaking to ensure everything is connected properly.

Remember, it is essential to clean and maintain your drain pan regularly to extend its lifespan. This includes checking for visible cracks, rust, or improper water drainage.

Reconnect the washer and check for leaks

Once you have installed the new drain pan, the next step is to reconnect the washer and check for leaks.

First, lift the washer and place it into the new pan. Then, hook the hot and cold water lines back up and turn the faucets on. Place the drain line back into the receptacle. If you have a new washer, you may need to install a drain pan pipe to the correct size using a hacksaw. If you are replacing a pan, you can use the existing drain pipe.

Next, plug the washer back into the outlet and turn the power back on. Use a wrench to ensure the hoses are secure. After the first few washes, check the drain pan to verify there are no leaks. If you still have leaks after you've tightened everything, dry off the fittings and place silicone around them. Wait 24 hours for the silicone to dry before using the washer.

A washing machine drain pan is designed to catch any leaks or drips from the hose connection and direct water away from the machine. This helps to prevent water damage to your floors and the ceiling of the floor below. Leaks are one of the most common causes of water damage in the home, so it is important to regularly inspect your washer and drain pan for any issues.
