Possible Causes
Partially blocked drain pump, Clogged drain hose, Obstructed sink trap spigot, Incorrect drain hose installation (siphoning)
How to Fix / Troubleshooting
Safety first: Disconnect power before accessing the pump or hoses.
Steps:
- Clean filters and sump: Remove filters and check the sump for debris. Remove any foreign objects.
- Check drain hose routing: Ensure the hose has a high loop under the counter to prevent backflow and is not kinked.
- Clean sink connection: Detach the hose from the sink trap or disposer and clear any blockage. Remove the disposer knockout plug if newly installed.
- Inspect pump: Access the drain pump from the base, check the impeller for obstructions, and ensure it spins freely.
When to call a technician: If the pump motor is faulty or the control board is not energizing it, professional repair is needed.
