Having to clean the kitchen utensils all by yourself is a thing of the past. A dishwasher is there to do it all for you.
As such, a kitchen without a dishwasher is unimaginable. But as efficient as these machines are, they might also have to be replaced at some point in time. And though you may have already installed the older model on your own, replacing it with a new one might seem tricky.
After all, you will need to remove some parts and retain some others, which you must be fully aware of. There are also several tricks to adopt and precautions to take for replacing a dishwasher. And most importantly, you must use a method that’s not too complicated.
So whether you are renovating your kitchen, or it is just time for a new dishwasher, we’ve designed this guide just for you to make the procedure effortless. So, let’s proceed and learn about the procedure, shall we?
Prior to discussing the method of replacing a dishwasher, we’ll deal with certain aspects that are key to completing the installation successfully. So, let’s move on.
All the tools you’ll need to replace a dishwasher are present in every household, so you can forget about fetching any specialised tools for the purpose. Plus, you won’t require altering the cabinets for fitting the new one if the replacement is of the same size as the older one. But if it’s not of the same size, you will need some advanced carpentry skills to make the new one fit perfectly.
Apart from this, you might find the portion of the floor in front of the old dishwasher raised slightly due to the additional flooring layers. This will ultimately make moving both the old and the new models a bit difficult. And in a few cases, you might even have to remove the flooring or loosen the countertop for the replacement.
Also, remember to cover the floor with a rug or a blanket to protect it during work.
Here are the tools you’ll need for the purpose:
Now, it’s time to look at the details of the procedure involved.
In the beginning, you’ll have to turn off the power to the dishwasher or unplug it from under the kitchen sink. You should also close the water supply at the shutoff valve nearest to the dishwasher. Note that this is usually located below the sink.
Plus, you should consider removing the doors of the cabinet at the base of the sink to make it easy to disconnect the drain lines when you begin the task.
Turn off the power supply to your dishwasher and remove the panel at the front. At this point, you must again use a voltage tester to verify whether the power supply to that part has stopped.
Then you need to disconnect all the wires and pull the cable from the box. Readying the wiring will come much later.
And it’s now that you’ll have to disconnect the electric power and water supply lines to the dishwasher. Note that both these connections are positioned underneath the old dishwasher, behind a lower panel at the front. So, you’ll have to unscrew this panel to access them.
Follow this by testing the line again with a voltage detector to check that the power supply is off. Now, remove the electrical power line, leaving the cable clamp on so that you can reuse it on the replacement dishwasher.
Sometimes dishwashers come in cord-and-plug connected forms instead of the hard-wired ones. In that case, you can disconnect the cord to reuse it on the new model.
As for the water supply line, it is usually made from braided stainless steel or flexible copper. In both cases, you’ll have to remove the nut securing this line to the 90-degree fixture on the dishwasher.
If the ring and nut are in perfect condition, you can leave them on the water line for reusing later on. After this, slightly bend the copper line while ensuring that it doesn’t kink. If it does, you must replace the line with those made from flexible stainless steel.
The 90-degree fixture must be removed at this point for use on the new model. Make sure you orient it in the same direction in the case of the new model so that the water line feeds into it directly. Now, remove any stagnant water inside the old one and remove the drain line below the sink.
When you’re sliding out the dishwasher, you’ll have to push the drain hose back through the hole in the sink cabinet. You can lower the dishwasher while taking it out as it will make the job easier.
At the start of this step, you must uncrate the replacement dishwasher as per the instructions given in the box. The installation instructions and the user manuals will be there inside the dishwasher, so get them out too. Review the instructions once before you proceed. On a side note, the steps might differ slightly from the ones we’ve included.
Tip the new dishwasher on the back and then attach the 90-degree fitting. Remember that you must not reuse the old sink drain hose as the dishwasher will surely come with a new hose. To keep the sink clogs from inundating the new model, make sure you loop the drain line up to the countertop bottom.
Notably, some plumbing codes will require a specialised air-gap fitting in the line. That’s why it will be best to call your local plumber to be sure about the rules for installing a dishwasher.
Then adjust the feet fixed on the dishwasher to ensure that it sits level with the opening. Follow this by grasping the sides of the dishwasher and sliding it in, and finally set it in place. Also, you should connect the water line to the dishwasher so that it doesn’t leak. The trick is to align the waterline so that it slides straightaway into the threaded portion of the elbow.
Now that the electrical cable, drain, and water supply line are connected to the dishwasher, switch on the power and open the water supply. Finally, check for any leakages, scan the positioning of all the parts for one last time and screw the machine to the countertop. And your new dishwasher is ready for use!
If installed in the right way, your new dishwasher will work just as fine as the old one, thereby ensuring that all utensils are clean and hygienic. So, don’t compromise on the hygiene of your family members and follow the steps for the replacement exactly as we’ve mentioned.
You must also remember to practice some safe-handling procedures for dealing with the machine. After all, most dishwashers are unwielded and heavy and consist of many sharp edges. And it’ll be best to rope in a family member or a friend to help you out with the procedure.
That’s about it for today. We’ll be back with more fun content soon, so stay tuned. Till then, all the best!
