How to Remove a Dishwasher

Removing a dishwasher is a project that most homeowners can tackle themselves with some preparation and care. While it may seem daunting, removing a dishwasher is straightforward when done methodically. With proper safety precautions and the right tools, you can have your old dishwasher removed in just a few hours.

Overview of the Dishwasher Removal Process

The general process for removing a dishwasher involves disconnecting it from utilities, removing mounting hardware, and sliding it out from under the counter. Here are the key steps:

1. Turn off electrical power and water supply lines
2. Disconnect drain and water lines
3. Remove mounting brackets/screws
4. Disconnect wiring (if hardwired)
5. Slide dishwasher out from under counter

While the overall process is simple, each step requires care and attention to detail. Having the right tools on hand will also make the job easier and safer.

Safety Tips for Dishwasher Removal

When removing a dishwasher, safety should always be your top concern:

• Turn off electricity at the breaker box – This prevents electric shock while handling wiring.
• Turn off the water supply – Relieves water pressure and allows safe line removal.
• Wear protective gloves – Guard against sharp edges and abrasions.
• Use caution when handling wiring – Prevent sparks or electrocution.
• Get help lifting – Dishwashers can be very heavy and awkward.
• Move slowly and carefully – Avoid pinches or crushed fingers during the removal.
• Set appliance down gently – Prevent damage to the flooring or dishwasher itself.

Rushing through the process or skipping safety steps can lead to personal injury or unneeded damage. Take things slowly and make safety the priority.

Tools and Supplies Needed

Having the right tools for the job will make dishwasher removal much easier. Here are some must-have items:

• Wrench or pliers – For loosening tubing, hose clamps, and mounting hardware.
• Screwdriver – Helpful for removing brackets or control panel covers.
• Flashlight – Illuminates dark areas under sink or along rear walls.
• Gloves – Protect hands from sharp brackets or hot wires.
• Bucket – Catches any residual water in hoses when disconnected.
• Towels – For wiping up small spills or drips.
• Voltmeter – For testing if power is off before handling wires.
• Dolly or furniture sliders – Allows appliance to be moved and lifted safely.
• Pencil and paper – To sketch out wiring connections before disconnecting.

Step 1: Turn Off Electrical Power and Water

The first step is to disconnect the dishwasher from its utilities. This prevents electric shocks and water leaks during the process.

Locate the electrical breaker box and switch the dishwasher circuit to OFF. Use a non-contact voltage tester on the wiring connections to confirm power is off.

For the water supply, look under the sink for the shut-off valve connected to the dishwasher’s water inlet hose. Turn the valve clockwise to shut off water completely. If there is no dedicated shut-off, you may need to turn off water at the main home valve.

Once electrical and water supply are safely disconnected, you can move on to the removal steps.

Step 2: Disconnect Drain and Water Lines

With the power and water off, you can now detach the drain and water lines from the dishwasher:

Drain Hose – This flexible hose runs from the dishwasher outlet to the home’s main drain line. Locate the drain hose clamp and loosen it with pliers. Once detached from the drain line, you can pull the hose free from the dishwasher port. Keep a small bucket handy to catch any water.

Water Supply Line – Find the water line that runs from the shut-off valve to the dishwasher’s inlet. Loosen any compression fittings or hose clamps to release the line. Again keep a bucket or towels ready for any residual water.

Detach any wire clamps or straps holding the lines in place. Remove as much of the line as possible to allow the dishwasher to pull free.

Step 3: Remove Mounting Brackets/Screws

Most dishwashers have mounting brackets that attach the frame to surrounding cabinets or countertops. Removing these allows the appliance to detach completely:

• Use a screwdriver to remove any visible screws along the front face, sides or top of the dishwasher.
• Look inside the tub for additional mounting screws that may be hiding behind racks, along the interior sides, or at the top.
• Brackets may be located under the bottom lip of the tub. Slide a flashlight in to locate hidden brackets.
• Some models have clamps that tighten around the adjacent cabinetry. Loosen these clamps completely using pliers or a wrench.
• Remove as much mounting hardware as possible to allow the dishwasher to detach.

Step 4: Disconnect Wiring (If Hardwired)

If your dishwasher is hardwired (no plug), you’ll need to disconnect the wiring before pulling the appliance free:

• TAKE CAUTION when handling electrical wiring.
• Make note of wire placement before disconnecting anything.
• Release any wire clamps or straps.
• Carefully remove wires from the dishwasher’s terminal block or connection points.
• Ensure wiring is clear of the removal path.

If you’re uncomfortable handling electrical wiring, contact an appliance repair professional to disconnect it safely.

Step 5: Slide Dishwasher Out from Under Counter

With all lines, hardware, and wiring detached, you’re ready to slide the dishwasher free:

• Position an appliance dolly or furniture sliders under the front legs. This allows the dishwasher to slide out smoothly.
• Tip dishwasher back slightly to get it over any lip or edge where it meets the flooring.
• Slowly and gently pull appliance straight away from its opening, watching for any snagged lines.
• Take care not to bend or distort the appliance body as you pull it out.
• Keep hands and feet clear of the slide path to avoid injury.
• Use caution not to scratch or damage surrounding cabinets or walls.

If needed, have a second person help steady and guide the dishwasher as it is withdrawn.

Step 6: Remove Any Remaining Hardware

With the dishwasher fully removed, you can take off any components that are left behind:

• Detach the water inlet valve from under the sink if it did not come free already.
• Remove any drain hose segment left attached to the home’s plumbing.
• Take off remaining mounting brackets, clamps orstrips from the sink cabinetry.
• Patch over any screw holes left in surrounding surfaces.

Dispose of old sealant, insulation, disconnected lines, and hardware appropriately.

What to Do with the Old Dishwasher

Once the dishwasher is fully removed, you’ll need to properly handle the appliance itself:

• Recycle responsibly – Most municipalities offer recycling for metal and plastic components that can be reused.
• Sell it – Dishwashers that are still functional can be sold via classified ads or resale sites.
• Donate – Charities may accept donations of working appliances for housing projects or resale.
• Dispose at a dump – If recycling isn’t an option, you can pay to have it disposed of properly.

Avoid placing older appliances out on the curb illegally. Handling removal responsibly keeps hazardous materials out of landfills.

Preparing the Space for a New Dishwasher

With the old unit removed, now is the perfect time to refresh the space for your replacement:

• Clean surrounding surfaces – Remove any gunk, debris or buildup from the cabinetry and floors.
• Seal cabinetry – Use caulk to seal any gaps or cracks around the dishwasher opening.
• Replace insulation – Dishwashers often have insulation blankets to reduce vibration. Install fresh insulation for a quieter appliance.
• Improve electrical and plumbing – Upgrade wiring, valves, or connections if needed.
• Adjust cabinetry – Modify cabinets or counter height if required for proper fit.
• Apply protective flooring – Lay down a moisture barrier mat or tray to protect flooring from leaks.

Taking these steps helps ensure your new dishwasher will install smoothly and function optimally.

Hiring a Professional for Dishwasher Removal

Removing a dishwasher takes time, physical effort, and some technical skills. For some homeowners, hiring a professional may be the wiser route:

Benefits of professional removal:

• Saves time and effort.
• No need to handle plumbing or electrical work.
• Allows old unit to be safely disposed of or recycled.
• Experts prevent damage to home and dishwasher.
• Licensed and bonded for liability protection.

Estimated cost of professional removal:

The average cost for professional dishwasher removal ranges from $50 to $150. Here are some pricing factors:

• Location and local rates.
• Dishwasher type and installation difficulty.
• Additional repairs needed during removal.
• Transport and disposal fees.
• Hourly vs flat rate pricing.

Getting an estimate from local appliance pros is the best way to gauge accurate pricing.

For most standard installations, professional removal is an affordable option that eliminates the hassle and hazards of DIY removal.

Overall, the process is pretty straightforward as long as you work methodically. Here are my thoughts on key steps:

Shutting off utilities – This is crucial for safety! Use a voltage tester on wires and open faucets to confirm.

Detaching lines/hoses – The drainage hose comes off easily once you loosen the clamp. Inlet hoses can be stubborn but a good wrench gets them loose.

Removing mounting hardware – Locating all the screws and brackets takes patience. I like to use a mechanics mirror to spot hard-to-reach ones.

Disconnecting wiring – If it’s hardwired, wiring makes me nervous for amateurs. Hire an electrician if you’re uncomfortable handling it.

Sliding it out – The smooth slide is so satisfying! Furniture glides or dollies are super helpful here. Just go slow.

Final removal – Get rid of any remaining bits left behind like hoses or valves. And seal up any gaps in the cabinetry.

Recommended Tools and Supplies

Having the right gear makes all the difference. Here are the must-haves I always keep on hand:

Tool	Purpose
Voltage tester	Confirming power is off
Flashlight	Illuminating dark spaces
Wrench/Pliers	Loosening fittings and hardware
Screwdriver	Removing brackets and panels
Gloves	Protecting hands
Bucket	Catching water
