If you’ve noticed standing water in the tub after a cycle, you likely have a clog that’s blocking the dishwasher from draining properly. Leftover food particles and other debris can build up in different areas of your appliance over time, leading to a clogged dishwasher. Pinpointing the location of the clog can help you get to the bottom of the issue.
COMMON SOURCES OF A CLOGGED DISHWASHER
1. DRAIN FILTER
If chunks of food are caught in your dishwasher’s drain filter, it won’t drain properly. To unclog it, remove the filter from the bottom of the dishwasher and wash it in hot, soapy water, gently scrubbing away the debris with a scrub brush. Inspect the drain area and clean off any debris before reinserting the filter.
2. SINK/GARBAGE DISPOSAL
Your dishwasher’s drain hose is typically connected to your kitchen sink and/or garbage disposal, which means if either one is clogged, your dishwasher may not be able to drain fully. Always run your garbage disposal before turning on the dishwasher in order to get rid of any food or debris in the drain system.
3. AIR GAP
Your dishwasher’s air gap prevents water from a clogged drain from overflowing back into the dishwasher. If the air gap becomes blocked, the dishwasher won’t be able to drain. To clean a clogged air gap, remove the chrome cover, unscrew the plastic cap, and use a plumber’s snake to remove any buildup.
