One of the most essential home appliances is undoubtedly the dishwasher. It saves us time, effort, and keeps our kitchen spotless — especially when the sink is full of dishes!
But did you know that there are several things most people don’t realize about how a dishwasher works?
Here are 5 amazing facts that will change the way you use yours!
💧 1. Your dishwasher uses less water than handwashing

It might surprise you, but your dishwasher actually uses much less water than washing dishes by hand.
- The average hand wash uses around 60 liters (16 gallons) of water.
- The average dishwasher cycle uses about 35 liters (9 gallons).
- And the most efficient models use only 15–20 liters (4–5 gallons) per cycle!
💡 Tip: This water saving is lost if you run the dishwasher only half full — always load it completely before starting a cycle.
⚡ 2. It also uses less energy

Less water means less energy needed to heat it!
That’s why dishwashers are often more energy-efficient than washing by hand — especially if you use eco or low-temperature cycles.
🧺 3. Modern dishwashers don’t have garbage disposals

Older dishwashers used to come with built-in food grinders.
Modern ones, however, use filters that need regular cleaning.
- Always scrape off large food bits before loading your dishes.
- You don’t need to rinse them, just remove the excess food.
- Clean the filter once every couple of weeks to keep the machine running smoothly.
💡 Extra tip: If your sink has a garbage disposal, run it briefly before the dishwasher — this ensures the drain line stays clear and prevents clogs.
🧽 4. It cleans better if you don’t pre-rinse

This is one of the most surprising facts!
If you pre-rinse your dishes, you’re actually making your dishwasher’s job harder.
Here’s why:
- The detergent needs a little residue to cling to.
- If dishes are too clean, the dishwasher’s sensors might think the load is easy and run a shorter, weaker cycle.
- You’ll end up with less clean dishes and wasted water.
So skip the pre-rinse — just scrape and load!
🌬️ 5. Leave the door open after a wash cycle

This simple trick comes straight from professional appliance technicians.
When your dishwasher finishes, open the door slightly to let the steam escape.
It:
- Helps release moisture faster
- Allows dishes to air-dry naturally
- Prevents mold or musty smells
- And saves energy by avoiding extra drying time
💡 Just crack the door open for 10–15 minutes after each wash — it really works!
