How to Set Up a Portable Dishwasher: Step-by-Step

What you need before you start

• The countertop dishwasher (unboxed and wiped clean)
• The faucet adapter (included in box)
• A flat spot on the counter within 5 feet of your sink
• An electrical outlet nearby
• Dishwasher detergent pods or powder

Step 1: Connect the faucet adapter

Look at the tip of your kitchen faucet. There's a small screen screwed on called the aerator. Unscrew it by turning counterclockwise. Set it aside in a safe place since you'll need it when the dishwasher is not in use.

Take the adapter from the dishwasher box. Most adapters have two ends: one fits a male thread, one fits a female thread. Thread the right end onto your faucet tip and tighten it by hand. Don't over-tighten. A light snug fit is enough.

Snap the inlet hose from the dishwasher into the adapter. You'll hear a click when it's locked. Give it a gentle tug to confirm it's secure.

Step 2: Position the unit

Place the dishwasher on the counter so the drain hose hangs naturally toward the sink. The drain hose should go over the sink rim without stretching. Keep the hose above the waterline inside the sink.

Leave 2 inches on each side of the unit for airflow. The back of the unit should sit at least 1 inch away from the wall. Check that the unit is level. Most countertops are fine, but if the unit rocks, use a small shim to stabilize it.

Make sure the power cord reaches your outlet without stretching or crossing a traffic area. A stretched cord is a trip hazard.

Step 3: Load the dishes correctly

Place plates and bowls facing the center spray arm. Cups and glasses go in the upper rack rim-down. Cutlery goes handle-down in the cutlery basket. Knives go blade-down.

Don't nest bowls or stack plates. Water needs to reach all surfaces to clean them. If items are touching, the water won't get between them.

Large pots and pans usually don't fit in countertop models. Wash those by hand. Items labeled "not dishwasher safe" include wooden spoons, cast iron, and hand-painted ceramics. Don't put those in.

Step 4: Add detergent and choose a cycle

Open the detergent door on the inside of the front panel. Add one detergent pod or the amount of powder the manual recommends for your cycle. Don't overfill. Too much detergent leaves residue on dishes.

For normal daily loads, use the Normal cycle. For lightly used glasses and cups, use the Quick cycle. For pots and baked-on food, use Heavy. If you're running the first cycle ever, run a Quick cycle with no dishes to flush the system.

Turn on your faucet fully cold before pressing Start. Some models only need the faucet on at the start of the cycle. Others draw water throughout. Check your manual.

Step 5: Manage the drain hose

The drain hose carries dirty water from the machine into your sink. Make sure it's draped over the sink rim and the open end is pointed down into the sink basin.

Use a small plastic hose hook or a binder clip to hold the hose in place on the sink rim. If the hose slips during a cycle, water will drain onto your counter. This is the most common setup mistake.

Never let the drain end sit in standing water inside the sink. Raise the hose higher than the water level if you have dishes soaking. Water will siphon back into the machine if the drain end goes below the water surface.

Quick tips for better results

• Scrape food off dishes before loading. You don't need to rinse, just remove chunks.
• Run a rinse-aid in the dispenser if your glasses come out spotted.
• Clean the filter once a week. It collects food debris and clogs fast in countertop models.
• Leave the door open an inch after the cycle ends to let steam escape and prevent odors.
• Run the hot water at the tap for 30 seconds before starting the machine. This gets hot water to the inlet faster.
