Dishwasher pods can be a convenient way to add detergent to a dishwasher instead of having to measure liquid or powder. But some socialmediaposts claim that using the dishwasher pods in the machine can lead to pipes clogging.
“Apparently when this powder is activated with water, it can get stuck in the pipes and create a thick, concrete-like barrier,” a viral Facebook post claims.
Multiple VERIFY readers, including Dawn and Larry, reached out to ask if it’s true that dishwasher pods are bad for pipes.

THE ANSWER
Dishwasher pods typically do not clog pipes. However, they can sometimes cause issues if they’re used improperly and any lingering residue from the outer film is left to build up in pipes.
WHAT WE FOUND
Dishwasher pods simplify the dishwashing process but they can sometimes clog pipes when used improperly. That’s because pods used contrary to dishwasher and product instructions can leave behind residue which builds up over time, and can in some cases eventually clog pipes.
“Powder dishwasher tabs are used safely and effectively in millions of homes on a weekly basis when they are used as directed and dishwasher appliance recommendations are followed,” the American Cleaning Institute says.
Dishwasher pods completely dissolve in water in order to clean and remove food residue, dishwasher pod manufacturer Reckitt told VERIFY, but it’s important to check that a dishwasher is compatible with dishwasher pods before use.
For example, some detergents “are not designed for shorter cycles, which can lead to pods not being fully washed out of the detergent dispenser,” Glenn Leon Graham, Director of Engineering Programs at GE Appliances said.
Dishwasher users should read their dishwasher instructional manual for the best place to put pods, as it can differ by machine, Robert Bair Plumbing says.
Bosch says dishwasher pods should be put “in the detergent compartment on the inside of the dishwasher door.” Similarly, Whirlpool says to place the pods in the dry detergent dispenser, rather than directly in the dishwasher tub which can prevent the pods from fully dissolving.
If dishwasher pods don’t completely dissolve, residue can build up, causing “a progressively thickening barrier that narrows the pipe’s diameter, impeding water flow and eventually leading to complete blockages,” All A’s Plumbing and Heating explains.
Robert Mazzacone, owner at Mazzacone Plumbing & Heating says that it’s “possible that the pods can leave a film or plastic residue behind,” so users should check dishwasher filters and “clean up the film or residue, as that could definitely clog pipes over time.”
Mark McCann, director of product marketing at Dishcare, recommends regularly cleaning a dishwasher filter bi-monthly with warm water and dishwasher soap. Food debris can also commonly lead to clogging in the filter or water pump so it’s important to check for that, too.
