How to Use a Dishwasher for the First Time: Step-by-Step Guide

Got a new dishwasher? Whether it's your first time ever using one or you've just moved into a new place, this step-by-step guide walks you through everything you need to know to get started — from setup to your first successful wash cycle.

Before Your First Run: Setup Checklist

1. Read the Manual

Every dishwasher is slightly different. Spend 10 minutes with the manual to understand your specific model's features, recommended detergent amounts, and any first-run instructions.

2. Check the Water Connection

Make sure the dishwasher is properly connected to your home's hot water supply and that the drain hose is correctly installed. If it's a new installation, run the kitchen tap until the water is hot before starting the first cycle.

3. Fill the Rinse Aid Dispenser

Locate the rinse aid dispenser on the inside of the door (usually next to the detergent compartment). Fill it with rinse aid before your first run. The Amazon Basics Dishwasher Rinse Aid (amzn.to/4v4Ts5b) prevents water spots and significantly improves drying performance. The dispenser holds enough for several weeks of washes.

4. Run an Empty Cycle First (Recommended)

Many manufacturers recommend running one empty cycle before loading dishes for the first time. This flushes out any manufacturing residue and primes the water lines. Add a dishwasher cleaner tablet for this first run. The Affresh Dishwasher Cleaner Tablets (amzn.to/42P5MKQ) are perfect for this — they clean the interior, pump, and hoses before you start using the machine for dishes.

Step-by-Step: Your First Load

Step 1: Scrape (Don't Rinse) Your Dishes

Scrape large food chunks into the trash. You don't need to pre-rinse — modern dishwashers and detergents are designed to handle food residue. Over-rinsing wastes water and can reduce cleaning performance.

Step 2: Load the Bottom Rack

Place plates, pots, pans, and bowls on the bottom rack. Face dirty surfaces toward the center spray arm, angled slightly downward. Don't stack or overlap items.

Step 3: Load the Top Rack

Place glasses, cups, and small bowls on the top rack, upside down and angled. Plastics always go on the top rack only. Secure lightweight items so they don't flip.

Step 4: Load the Cutlery Basket

Mix forks and spoons handles-up and handles-down to prevent nesting. Knives always blade-down for safety. Don't overload the basket.

Step 5: Add Detergent

Open the detergent dispenser on the inside of the door. Add one dishwasher pod or the recommended amount of powder/gel. The Finish Powerball Dishwasher Pods (amzn.to/3RE929j) are the easiest option — just drop one pod in and close the dispenser. No measuring needed.

Step 6: Check the Spray Arms

Give the spray arms a spin by hand to make sure nothing is blocking them. This is one of the most important habits for getting clean dishes every time.

Step 7: Select Your Cycle

For a first load, use the Normal cycle. This is the right setting for most everyday loads. Select Heated Dry if you want dishes fully dry, or skip it to save energy (rinse aid helps dishes air dry quickly).

Step 8: Start the Dishwasher

Close the door firmly until it clicks, then press Start. Most dishwashers take 1–2 hours to complete a Normal cycle.

Step 9: Unload Bottom Rack First

When the cycle is done, unload the bottom rack first. This prevents water that has collected on top of items on the top rack from dripping onto the clean dishes below.

Ongoing Maintenance Tips

• Check and refill the rinse aid dispenser monthly
• Clean the dishwasher filter every 1–3 months (check your manual for location)
• Run a cleaning cycle monthly with Affresh tablets
• Wipe down the door gasket regularly to prevent mold
