Knowing How to Remove a Built-in Dishwasher is a relatively simple task for most DIY homeowners. Whether you’ve just bought a new dishwasher or your old one is ready for the dumpster, Now is an excellent time to learn how to remove an old dishwasher or install a new one.
You might ask, “Can I replace a dishwasher myself?” The answer for most homeowners is Yes, as long as you have a good plan.
Following the basic steps (below), most people can remove a dishwasher in 30-45 minutes. Installing a new one requires about 45-60 minutes.
These days, a Built-in dishwasher is a convenient and almost necessary addition to any home kitchen.
However, like all major appliances, dishwashers have a limited lifespan – usually 8-10 years maximum – and will need to be replaced eventually.
When Should You Replace Dishwasher?
There are many signs that it may be time for a new dishwasher. If the problem is simply that the dishwasher is not draining correctly, clearing the drain at the bottom of the dishwasher can be a straightforward fix.
However, If your dishwasher cuts itself off mid-cycle or isn’t heating water properly, it’s likely time for a replacement.
Remember that hiring a plumber to repair a dishwasher door, circuit motherboard, or heating element can cost more than simply replacing the dishwasher.
Signs It’s Time To Replace Your Dishwasher:
- The dishwasher is eight years or older, and runs inefficiently.
- Dishes are Not Hot after a dishwashing cycle.
- The dishwasher doesn’t drain completely (and the bottom drain is clear)
- The dishwasher door doesn’t latch properly
- The dishwasher shows signs of Rust
- The dishwasher leaks water (and the water and drain line are secure)
- The dishwasher has cracks on the interior cabinet
- Any combination of the above dishwasher problems.
As a rule of thumb, If your dishwasher is over eight years old and shows some of the problems described above, it’s probably time to replace it with a new dishwasher.
Follow these Ten Steps below – to Remove a Dishwasher quickly, safely, and without creating a huge mess.
How to Remove Built-in Dishwasher – 10 Steps
- Average Time for This Project: 1 Hour or Less
- DIY Skills Required: 7 (one scale of 1-10, with “10” being the most complex)
Step 1: Clean Out the Sink Cabinet
The first step in changing your dishwasher is to expose the water shut-off valve by removing the contents from the cabinet underneath your sink.
This will give you clear access to remove the old dishwasher drain line and inspect the existing plumbing connections for any kinks or existing leaks.
Step 2: Shut off the Power to the Dishwasher
Before you do anything else, shut off the electrical power to the dishwasher. Locate your electrical breaker panel and turn off the ability for the dishwasher electrical circuit.
This is also why we recommend this job as a “daytime” job where you will have plenty of daylight.
Tip: If your electrical circuits are not marked at the breaker panel, turn the dishwasher on to the “dry cycle” to illuminate the power on the dishwasher, then have someone tell you when you have tripped the connecting circuit “off.
Step 3: Shut Off the Water To The Dishwasher
The water supply shut-off valve for most dishwashers is typically located in the cabinet underneath the sink (see image below) and is in line with your dishwasher.
Turn off the dishwasher’s water supply entirely by turning the shut-off valve clockwise until fully closed.
Step 4: Disconnect Wiring To the Dishwasher
Modern dishwashers have a short “removable panel” on the bottom front of the dishwasher. This front panel is typically placed with clips or two small screws.
Once you have removed the front panel, use a flashlight and locate the electrical wiring harness near the dishwasher’s front. Test black and white wires with a voltage meter to ensure the power is off.
Remove the dishwasher electrical box/cover containing the wires, but first, test the black and white wires with a voltage meter to ensure the power is off.
Then remove the wired connections one at a time, starting with the ground wire (green), then the white (neutral), and then the black (hot) wire.
Note: Before removing any wires, use a handheld voltage tester to check and ensure the circuit is off, even if you’re sure you flipped the correct breaker in the first step.
Hardwired Connections – On occasion, you may find that the wiring harness and electrical box are hardwired to Romex (flexible electrical cable) and plugged into the wall behind the dishwasher or hardwired to a nearby electrical outlet.
If this is the case, and after you have removed the waterline (see step 6), slowly pull the dishwasher away from the wall to expose it, then remove the hardwired plug from the wall or the hardwires from the junction box.
If you are unsure or have any questions, Seek advice from a Professional Electrician.
Step 6: Disconnect the Water Line
Next, you’ll want to remove the heated water supply line. Most dishwashers have the water line accessible when the bottom panel on the front of the unit is removed.
Before proceeding, keep a pan or towel handy to catch any water coming out when the cord is disconnected.
Make sure the water supply valve under the sink is turned off. Loosen the nut that holds the line in place, then allow it to drain into a shallow pan or towel.
Step 7: Disconnect the “Drain” Line
Remove any standing water inside the old dishwasher. Next, remove the old dishwasher drain line by accessing its connection underneath your sink.
The flexible drain line will be connected to your garbage disposal (seen below) or your PVC sink drain pipe (if you don’t have a garbage disposal).
Step 8: Pull the Dishwasher Out
To remove the old dishwasher, remove the two screws from the clips that hold your dishwasher in place. (These two clips are located underneath the countertop).
Carefully lift the two front leveling legs onto an old towel to protect your flooring, and slowly slide the dishwasher out.
Remember that the drain line is still connected. Ensure you pull the dishwasher out slowly and the drain line is set free from the sink cabinet.
Step 9: Remove and Dispose of Your Old Dishwasher
Now that the electrical hookups, water supply, and drain lines have been disconnected, you should be able to slide the dishwasher gently out of the space it occupied; again, use a towel to keep it from scratching up your kitchen floor.
Allow any remaining water from the lines to drain into buckets, then remove the dishwasher, setting it aside to take to a recycling center that accepts appliances.
Check with your new supplier first. Sometimes, delivering new appliances includes hauling away the old dishwasher for a small fee.
Step 10: Clean Up the Area
No matter how careful you are, removing a built-in dishwasher will result in at least some minor water spills.
After the dishwasher is out of the way, thoroughly go over the area with a clean, dry towel to remove water from the floor or under the counters.
This is a great time to double-check for any plumbing leaks. Since the space under the old dishwasher will not have been cleaned in many years, you should also mop and clean it before installing your new dishwasher.
Congratulations. Now you know how to replace and install a dishwasher. You just saved $125 – $200 in plumbing bills. Pretty good day 🙂
