This siphon break elbow is a 90-degree connector used in the drain path to create an air break that helps prevent back-siphoning. Replacing a cracked or obstructed elbow can stop leaks and restore proper draining performance.

  • Maintains the atmospheric break that prevents wastewater from siphoning back into the appliance
  • Helps route drain flow without kinking or stressing the hose
  • Common symptoms: leaking at the elbow area, water backing up through the drain line, slow or incomplete draining, visible cracks or damage
What's included: 1 elbow fitting Installation notes:
  • Disconnect power; turn off water supply if applicable
  • Expect residual water—protect the area with towels or a pan
  • Release hose clamps, note orientation, fully seat hoses on the new elbow, and secure clamps
  • Run a test and check for leaks

Hello John. You will need to remove the front panel from the washer and remove the screws securing the top and raise the top. Once raised, you will remove the screws securing the siphon break and the elbow WPW10116738 Then remove the old elbow and reinstall with the new elbow in reverse order. Hope this helps.
