#### Why Uninstall a Dishwasher?
Before we get into the how-to, it’s worth understanding why you might need to remove a dishwasher. Common reasons include upgrading to a new model, repairing a leak, relocating the appliance, or preparing a home for sale. Whatever your reason, following a systematic process ensures you avoid damage to your kitchen, the dishwasher itself, or your plumbing and electrical systems.

– **Bucket** or **shallow pan** (to catch water)
– **Towel** or **rag** (for spills)
– **Voltage tester** (to confirm the power is off)
– **Work gloves** (to protect your hands)

### Step-by-Step Guide to Uninstalling a Dishwasher
#### Step 1: Turn Off the Power
Safety comes first. “Before you begin, make sure to turn off the power supply to the dishwasher at the circuit breaker box,” advises the experts at Lowe’s. Locate your home’s electrical panel, find the breaker labeled for the dishwasher (or kitchen appliances), and switch it off. Use a voltage tester at the dishwasher’s power connection to double-check that no current is flowing. This step prevents electrical shock during removal. [(( Lowe’s ))]
#### Step 2: Shut Off the Water Supply
Next, stop the water flow to avoid a mess. Under your kitchen sink, locate the shut-off valve connected to the dishwasher’s water line—usually a small knob or lever. Turn it clockwise until it stops. If your dishwasher doesn’t have a dedicated valve, shut off the main water supply to your home. “Not sure where the valve is? It’s often a copper or flexible line running from the shut-off to the dishwasher,” notes Bob Vila’s team. [(( Bob Vila ))] After shutting off the water, run the dishwasher for a few seconds to drain any remaining water in the lines.
#### Step 3: Prepare the Area
Place a bucket or shallow pan under the sink where the water line connects to catch any drips. Lay down a towel to soak up spills. Clear out any items stored in the cabinet beneath the dishwasher to give yourself room to work. If your dishwasher door is open, lower it fully to access the mounting screws.
#### Step 4: Disconnect the Water Supply Line
Using an adjustable wrench, loosen the nut connecting the water supply line to the dishwasher’s inlet valve (typically located at the bottom front or side of the unit). Be prepared for some water to spill out—this is normal. Once disconnected, set the line aside and let any residual water drain into your bucket. “Wear gloves here to keep your hands dry and avoid slipping,” suggests Family Handyman.

#### Step 5: Disconnect the Drain Hose
The drain hose is usually attached to either the garbage disposal or a separate drain pipe under the sink. Loosen the clamp holding it in place (often a hose clamp requiring pliers or a screwdriver) and gently pull the hose free. Have your bucket ready, as leftover water may pour out. If the hose is stiff or stuck, wiggle it gently to avoid damaging the connection point.
#### Step 6: Disconnect the Electrical Wiring
Most dishwashers are hardwired or plugged into an outlet. First, remove the access panel at the bottom front of the dishwasher (usually held by a few screws). If it’s plugged in, simply unplug it. If hardwired, use a screwdriver to remove the junction box cover, then untwist the wire nuts to separate the dishwasher wires from the house wiring. “Always double-check with a voltage tester before touching wires,” warns This Old House. [(( This Old House ))] Tuck the house wires back into the junction box and secure the cover temporarily.
#### Step 7: Remove the Mounting Brackets
With the utilities disconnected, it’s time to free the dishwasher from the countertop or cabinets. Open the dishwasher door and look for screws or brackets at the top or sides securing it in place. Use a screwdriver to remove them—there are typically two at the top and sometimes additional ones on the sides. Keep these screws in a safe spot if you plan to reuse them later.
#### Step 8: Slide Out the Dishwasher
Gently pull the dishwasher forward. It may resist due to leveling legs or friction, so tilt it slightly or adjust the legs with a wrench if needed. “If it’s stuck, check for hidden screws or clips you might have missed,” advises HGTV. Once it’s out, inspect the space for any water damage or debris that needs attention before installing a new unit.

### Additional Tips for a Smooth Removal
– **Check Local Codes**: Some areas require a licensed plumber or electrician for disconnection. Verify your local regulations.
– **Label Connections**: If you’re reinstalling a dishwasher later, label the wires and hoses with tape to simplify the process.
– **Dispose Properly**: Dishwashers contain metal and plastic components. Check with your local waste management for recycling options.
– **Cap the Water Line**: If you’re not replacing the dishwasher right away, cap the water line with a pipe cap to prevent leaks.

### Common Mistakes to Avoid
– **Skipping the Power Check**: Always confirm the power is off—don’t assume the breaker is correct.
– **Forgetting the Water Supply**: Failing to shut off the water can flood your kitchen.
– **Pulling Too Hard**: Forcing the dishwasher out can damage flooring or cabinets.
