Kill the power and the water first
Turn off the breaker that feeds the dishwasher and confirm the controls are dead before you pull the unit out. Shut the hot-water valve under the sink and disconnect the supply and the drain hose into a pan. A dishwasher that looks empty still holds water in the sump, and that water will pour out when you tip the tub. Bail or sponge it now, in the kitchen, not in the truck. Have a qualified person disconnect a hard-wired unit if you are not comfortable with the junction box. Do not cut a live cord and do not leave the water valve seeping under the sink after the machine is gone. Coil the hoses and bag loose clamps so they are not hiding in the insulation blanket.
Scrap metal or bulky trash
An intact steel dishwasher is often a scrap-metal candidate, but only if the yard accepts appliances and wants the motor and insulation still attached. Call and ask. A transfer station or landfill may take it as bulky waste instead. Tell them it is drained and that the power is disconnected. Do not describe it as a refrigerant appliance. A standard dishwasher does not use refrigerant, and calling it one sends you to the wrong line. If the unit flooded and is full of mold, say that too. Donation is a poor fit for a dead dishwasher. Leave it out of the curbside cart, which it will not fit, unless a bulky pickup you scheduled specifically allows appliances.
Move it upright until you are ready to lift
Dishwashers are awkward because the weight sits low and the door can fall open. Latch the door, tape it if the latch is broken, and walk the unit on a dolly. Do not lay it on its back in the house and then drag it, because residual water will run into the controls and then onto the floor. In the truck, set it upright against the cab and strap it so a turn cannot tip it onto its face. At the bay, unload where appliances or scrap are assigned. If the attendant sees water pouring out, they may send you back to finish draining it. Check the bed for screws and for the kick plate before you leave.
Before you go
- Switch off the breaker, shut the water, and disconnect the supply and drain into a pan.
- Empty the sump so the tub will not pour when it tilts.
- Ask a scrap yard or the disposal site which one accepts drained dishwashers.
- Latch the door, strap the unit upright, and unload in the assigned bay.

Questions people ask
Does the insulation blanket have to come off?
Only if the scrap yard asks for it. Otherwise leave it on, and pick up any pieces that fall off in the bed so they do not blow around the site.
Can the hoses stay attached?
Cap or bag them so they do not drip. Ask the yard whether rubber hoses must come off before the unit is accepted as metal.
Search Dumpmapper by ZIP code or city, then call the site before you load the truck. Hours and accepted materials change.
