Before ordering:
-
Verify your dishwasher’s model number and serial number.
-
Check the design of your existing check-valve (connection style, mounting, hose attachment) to ensure this replacement will match.

If the drain hose, pump or filters are clogged or damaged, replacing the check-valve alone may not fully restore function — consider having a maintenance technician inspect the full drainage path.
