When it comes to home appliances, dishwashers are one of the most important. They save time and energy, and they can help to keep your kitchen clean and organized. But what happens when your dishwasher starts to act up? Or, worse yet, what if it breaks down completely? If you're not sure how to fix it, you may be tempted to call a repairman. However, there are actually a few things you can do yourself to troubleshoot and repair your dishwasher. In this article, we'll show you how to remove an old dishwasher so you can replace it with a new one.
Before you start, it's important to gather all of the tools and materials you'll need. You'll need a screwdriver, a pair of pliers, a putty knife, and a bucket. You may also need a flashlight to help you see in dark areas. Once you have all of your tools and materials, you can begin the process of removing your old dishwasher.
The first step is to turn off the water supply to your dishwasher. You can do this by turning off the valve under the sink. Once the water supply is turned off, you can disconnect the water lines from the dishwasher. To do this, simply use a pair of pliers to loosen the nuts that hold the water lines in place. Once the water lines are disconnected, you can move on to the next step.
Preparing for Dishwasher Removal
----------
Before removing an old dishwasher, it's crucial to prepare thoroughly to ensure safety and efficiency. This involves several key steps:
### Disconnecting Utilities ###
* **Water supply:** Locate the water supply line connected to the dishwasher and turn off the valve. Use a wrench to disconnect the line from the dishwasher's inlet valve.
* **Electrical:** Identify the electrical outlet or circuit breaker powering the dishwasher and turn it off. Unplug the dishwasher from the outlet or disconnect it from the circuit breaker.
* **Drain hose:** Locate the drain hose attached to the dishwasher's disposal or sink drain. Detach the hose from the dishwasher and secure its open end to prevent water leakage.
### Clearing the Dishwasher ###
* **Remove contents:** Empty the dishwasher of all dishes, cutlery, and utensils.
* **Clean interior:** Wipe down the interior of the dishwasher, including the racks, door, and gaskets, with a damp cloth or sponge to remove any food debris or detergent residue.
* **Check drain**: Inspect the dishwasher's drain filter and clean it if necessary to prevent any blockages.
### Preparing the Appliance ###
* **Secure door:** Open the dishwasher door and remove the door springs or hinges to prevent accidental movement during removal.
* **Disconnect hoses:** In addition to the water supply and drain hoses, disconnect any other hoses, such as a rinse aid line, if applicable.
* **Remove screws:** Locate and remove the screws holding the dishwasher in place, typically at the base of the appliance and along the sides.
* **Check for stability:** Ensure that the dishwasher is stable and secure before attempting to lift or move it.
Disconnecting Water and Power Sources
----------
Before removing your old dishwasher, it is crucial to disconnect both the water and power sources to ensure your safety and prevent any potential damages. Follow these steps carefully:
### Water Disconnection ###
1. Locate the water supply valves beneath the sink connected to the dishwasher's water line. They are typically located behind a small panel or under the sink cabinet.
2. Using a wrench or pliers, turn off both the hot and cold water supply valves by turning them clockwise.
3. Disconnect the water line from the dishwasher by unscrewing the nuts that hold it in place. You can use a wrench or pliers to loosen them.
### Power Disconnection ###
| Type of Power Source | Disconnection Instructions |
|------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
|**Hardwired Connection**|1. Identify the electrical panel that serves your kitchen and turn off the electricity to the dishwasher circuit from the breaker box.<br/>2. Remove the cover plate from the dishwasher's junction box (usually located behind or beneath the dishwasher) using a screwdriver.<br/>3. Disconnect the electrical wires from the junction box by unscrewing the wire nuts and carefully pulling them apart.|
| **Plug-In Connection** | 1. Locate the electrical outlet where the dishwasher is plugged in.<br/>2. Unplug the dishwasher from the outlet. Make sure to pull on the plug, not the cord. |
### Emptying and Cleaning the Dishwasher ###
Before you begin the process of removing your old dishwasher, it's essential to empty and clean it thoroughly. This will make the process easier and safer.
#### Step 1: Unload all dishes and utensils ####
Remove all dishes, utensils, and any other items from the dishwasher. Be sure to check the silverware basket, racks, and any other compartments where items may be hidden.
#### Step 2: Clean the filter ####
Locate the filter at the bottom of the dishwasher tub and remove it. Use a brush to remove any food particles or debris trapped in the filter. Rinse the filter thoroughly with hot water and replace it.
#### Step 3: Run a cleaning cycle with detergent ####
Add a dishwasher cleaning tablet or detergent to the dispenser and run the dishwasher on a hot water cycle. This will help to remove any remaining food residue, grease, and odors from the dishwasher's interior.
#### Step 4: Wipe down the interior ####
After the cleaning cycle is complete, use a damp cloth or sponge to wipe down the interior of the dishwasher, including the door gasket, racks, and tub. This will remove any remaining moisture or debris.
Once your dishwasher is empty and clean, you're ready to disconnect it from the power supply, water lines, and drain hose. Then, you can carefully remove the dishwasher from its housing and dispose of it properly.
Removing the Dishwasher Door
----------
### 1. Disconnect the Dishwasher from Power and Water ###
Locate the dishwasher's power cord and water supply hose. Unplug the cord from the electrical outlet and shut off the water valve by turning the knob clockwise. Unhook the water supply hose from the dishwasher's inlet valve.
### 2. Open the Dishwasher Door and Remove the Screws ###
Open the dishwasher door fully. Look along the top edge of the door for screws or bolts that secure it to the dishwasher frame. Remove the screws or bolts carefully.
### 3. Lift the Dishwasher Door Off the Hinges ###
Once the screws or bolts are removed, carefully lift the dishwasher door straight up and off the hinges. The door is heavy, so it's best to have two people perform this step to avoid any accidents.
### 4. Disconnect the Wires and Water Supply Line from the Door ###
Inside the dishwasher, locate the wires and water supply line that connect to the dishwasher door. Disconnect the wires by pressing on the release tab or unscrewing the connectors. Disconnect the water supply line by unscrewing the fitting.
| Wire Color |Function|
|--------------------|--------|
| Black | Power |
| White |Neutral |
|Green or Bare Copper| Ground |
Once the wires and water supply line are disconnected, you can completely remove the dishwasher door from the appliance.
Detaching the Dishwasher from the Cabinetry
----------
Uncoupling the dishwasher from its cabinetry involves several steps to ensure safe and efficient removal. Follow these guidelines to detach the dishwasher successfully.
#### 1. Disconnect the Power Supply ####
Locate the electrical outlet servicing the dishwasher and unplug it, ensuring the power is disconnected.
#### 2. Turn Off the Water Supply ####
Find the water supply valve connected to the dishwasher and turn it off. This will prevent water from leaking during the removal process.
#### 3. Remove the Toe Kick ####
Locate the toe kick, a small panel covering the bottom of the cabinetry. Remove the screws or clips holding it in place to expose the dishwasher's base.
#### 4. Unscrew the Mounting Brackets ####
Identify the mounting brackets securing the dishwasher to the cabinetry. Using a Phillips head screwdriver, unscrew these brackets to loosen the dishwasher's connection to the cabinet.
#### 5. Pull the Dishwasher Forward ####
With the mounting brackets removed, gently pull the dishwasher forward about 6-8 inches. Keep it slightly slanted downward to avoid catching on the floor or cabinetry. Ensure there is enough clearance to disconnect the remaining connections, such as the drain hose and power cable.
