More Details

This is a high-quality drain filter for your dishwasher.

During each wash cycle, food scraps and bits of debris get rinsed off your dishes and flushed into the dishwasher’s water. The drain microfilter steps in to catch those particles—so they don’t end up back on your clean plates and glasses.

If the filter becomes clogged, it can block water flow, slow down drainage, and even cause water to back up inside your machine. If you're noticing standing water or less-than-sparkling results, it might be time for a new one. Swap it out with this replacement part.

This dishwasher drain filter fits all the other suitable brands from the list above.
