MAPICan You Use Regular Dish Soap in a Dishwasher?

No. Whirlpool says you should use dishwasher detergent, not regular dish soap. Hand dish soap creates thick sudsy foam that can overflow from the appliance.
no
The answer
No. Whirlpool says regular dish soap should not be used in a dishwasher because it creates thick suds and bubbles that can overflow through the dishwasher door.
Why
Automatic dishwasher detergent is designed for the machine without relying on the same sudsing action as hand dish soap. Whirlpool recommends using only dishwasher-approved detergent.
When it is usually OK
- Use detergent formulated for automatic dishwashers.
- If regular dish soap was added accidentally, stop the cycle and follow the manufacturer's cleanup guidance.
When you should not
- Do not substitute hand dish soap for dishwasher detergent.
- Do not continue a cycle when excessive dish-soap suds are spilling or building up.
Risks and exceptions
- Regular dish soap can create excessive suds.
- The suds can overflow through the dishwasher door.
- Remaining dish-soap residue can require additional rinsing and cleanup.
Best practice
Use only detergent approved for automatic dishwashers. If dish soap was used accidentally, stop the cycle and follow the dishwasher manufacturer's instructions for draining and clearing the suds.
Alternatives
- Hand-wash dishes until you have proper dishwasher detergent.
- Use an approved liquid, powder, tablet, or pod made for automatic dishwashers according to the appliance instructions.
