Dishwasher does not drain after connecting to GE garbage disposal

Safety first: Turn OFF power to the disposal and dishwasher.

• Step 1 – Check knockout plug: Disconnect the dishwasher drain hose from the disposal inlet. Shine a light into the inlet; if you see a solid plastic wall, the knockout plug is still in place.
• Step 2 – Remove knockout: Insert a screwdriver into the inlet and tap gently with a hammer to knock out the plug. Retrieve the loose plug from inside the disposal chamber with tongs.
• Step 3 – Inspect hose: Ensure the dishwasher hose is not kinked or pinched and is routed with a proper high loop or air gap.
• Step 4 – Reconnect and test: Reattach the hose with a secure clamp, then run a dishwasher drain cycle to confirm proper operation.

Warning: Do not leave the knockout plug loose inside the disposal; it can jam the impellers.
