Do not put Dawn or any dish soap in your washing machine

Dawn dish soap will damage your washing machine. It creates far too many suds for a washing machine to handle, and those suds will leak out onto your floor, into the drum seal, and potentially into the motor. Even a small amount — a tablespoon or two — can cause problems. Dish soap is formulated to create thick, long-lasting bubbles for hand-washing dishes. Washing machine detergent is formulated to break down quickly and produce minimal suds, because the machine needs water to flow freely through the drum.

If you have already put dish soap in your machine, stop the cycle when ready, drain it if possible, and run two or three empty hot-water cycles to rinse out the suds. Do not run another load of laundry until the machine stops producing bubbles when you open the door.

Key Takeaways

  • Dish soap creates excessive suds that can overflow from your washing machine and damage internal seals and the motor.
  • Washing machine detergent is specifically formulated to produce minimal suds and work with the machine's water flow.
  • If you accidentally use dish soap, run two to three empty hot-water cycles to rinse it out before using the machine again.
  • Bar soap, laundry soap, and other household soaps will also cause problems and should not be substituted for washing machine detergent.

What happens when dish soap enters the drum

Dish soap breaks down grease and food particles by creating stable bubbles that trap dirt. In a washing machine, those bubbles do not break down the way they do in a sink. The machine's agitation and water jets make the problem worse, not better — they whip the soap into more suds. Within minutes, suds will overflow from the detergent dispenser, leak around the door seal, and fill the drum faster than the drain can empty it.

Those suds can force their way into the rubber gasket that seals the door, where they sit and promote mold growth. They can also reach the pump and motor, coating internal parts and reducing their ability to work. Over time, repeated exposure to dish soap residue can shorten the life of these components.

Why washing machine detergent is different

Washing machine detergent contains suds suppressants — chemicals that prevent bubbles from forming in the first place. These suppressants allow the detergent to clean clothes while keeping the water flowing freely through the drum and drain. The detergent is also designed to work in the specific water temperature and agitation pattern of your machine.

High-efficiency (HE) machines use even less water, so they require detergent with even fewer suds. Using regular detergent in an HE machine can still cause overflow, though not as severely as dish soap would. Always check your machine's manual or the label on the detergent bottle to confirm you are using the right type.

Other soaps that will also cause problems

Dish soap is the most common mistake, but other household soaps will damage your machine in similar ways. Bar laundry soap, hand soap, body wash, and shampoo all create excessive suds. Even some "natural" or "eco-friendly" detergents produce more suds than a washing machine can handle — read the label or test a small amount in a sink first if you are unsure.

Fabric softener is not a soap, but it can also cause problems if overused. Stick to the amount recommended on the bottle, and never pour it directly into the drum — use the dispenser drawer if your machine has one, or dilute it in water first.

How to clean your machine after an accident

If you have already run a load with dish soap, the first step is to stop the machine and let it drain. If suds are still visible in the drum, do not start another load. Instead, run an empty hot-water cycle with no detergent. Let the cycle complete, then open the door and check for suds.

Repeat this process two or three times until you no longer see bubbles when you open the door after a cycle. This may take 30 minutes to an hour total. If your machine has a cleaning cycle (some newer models do), you can run that instead, though empty hot-water cycles usually work just as well.

After the machine is clean, wipe down the rubber gasket around the door with a dry cloth to remove any remaining soap residue. This helps prevent mold from growing in that damp area.

What to use instead for tough stains

If you were reaching for dish soap because you have a greasy or oily stain, there are better options that will not damage your machine. explore a small amount of liquid laundry detergent directly to the stain, let it sit for 5 to 10 minutes, then wash the garment in cold water. For grease stains, this works better than dish soap anyway, because laundry detergent is designed to work in the washing machine's water temperature and agitation.

For other tough stains — blood, wine, grass — use a stain remover product made for laundry, or try white vinegar, hydrogen peroxide, or baking soda depending on the stain type. These options are safe for your machine and often more effective than dish soap for the specific stain you are trying to remove.

Frequently Asked Questions

Will one squirt of dish soap ruin my washing machine?

One small squirt is unlikely to cause permanent damage, but it will still create excess suds and may leak onto your floor. Stop the cycle, drain the machine, and run empty hot-water cycles to rinse it out. Check the drum and gasket for remaining bubbles before running another load.

Can I use dish soap if I dilute it with water?

No. Diluting dish soap reduces the concentration, but it does not change the fact that it creates excessive suds in a washing machine. Even diluted, it will cause overflow and potential damage to seals and the motor. Use washing machine detergent instead.

What if my washing machine detergent is empty and I need to wash clothes now?

Do not substitute dish soap, bar soap, or other household products. Instead, wash the load in cold water with no detergent — many stains will rinse out with water alone. Buy the correct detergent and use it for the next load, or hand-wash the garment if it needs cleaning before you can get to a store.

Is there any dish soap that is safe for washing machines?

No. All dish soaps are formulated to create stable suds for hand-washing. None of them are designed for washing machines, and none will work safely in one. Stick to products labeled as washing machine detergent.
