Possible Causes
Partially clogged drain filter, Food debris in the drain pump, Drain hose installed too low or without a high loop, Obstruction at the sink or garbage disposal connection
How to Fix / Troubleshooting
Safety first: Turn off the power and be cautious of sharp debris in the sump.
- 1. Clean filters: Remove and clean the filter assembly and check the sump for any debris.
- 2. Inspect drain pump: Access the drain pump from the bottom, remove the pump cover if possible, and clear any obstructions from the impeller.
- 3. Check drain hose routing: Ensure the hose has a high loop under the counter to prevent backflow and is not kinked.
- 4. Sink connection: Remove the hose from the sink tailpiece or disposal and check for clogs. Clear as needed.
After clearing, run a rinse cycle to confirm proper drainage.
