GE Dishwasher Not Draining — What’s Happening
When a GE dishwasher is not draining, the machine detects standing water in the tub or cannot complete the drain cycle. GE treats this as a drain-system failure rather than a single fault code. The water cannot leave the tub because something is blocking the flow path or the machine is not sensing the water level correctly.
In some model families you may see an FTD or FED error displayed, which stands for Failure to Drain. The most common root causes are mechanical blockages in the drain hose, filters, or sink connection. A clogged pressure sensor or pressure-sensing circuit is also a frequent cause in technician field experience, even when the drain pump itself is working fine.
Most Likely Causes
- Kinked or blocked drain hose The hose under the sink can become crushed, kinked at the connection point, or filled with debris, preventing water from leaving the dishwasher.
- Clogged dishwasher filters or sump area Food debris such as noodles, lettuce, or bones collects in the filter basket and sump, blocking the drain path at the bottom of the tub.
- Blocked garbage disposer or knockout plug left in place If the dishwasher drains into a disposer, a clogged disposer or a knockout plug that was never removed during installation will stop water flow.
- Air gap blockage When an air gap is installed on the sink, debris can clog the cap and prevent the drain hose from venting properly.
- Missing or improper high drain loop If no air gap is used, the drain hose must loop up under the counter to the height specified in the installation instructions or water may not drain correctly.
- Clogged pressure sensor assembly Sludge or detergent buildup in the pressure sensor or its elbow prevents the machine from detecting that water has drained, triggering a fault even when the pump runs.
- Oversudsing from wrong detergent Using the wrong detergent or too much detergent creates excess suds that interfere with the drain cycle and water-level sensing.
How to Diagnose and Fix
- Turn off power at the breaker and shut off the water supply valve under the sink.
- Check the drain hose under the sink for kinks, crushing, or blockage, then straighten or replace the hose if damaged.
- Run the garbage disposer and confirm the sink drain is clear, then verify the disposer knockout plug was removed if the dishwasher was connected to a newly installed disposer.
- If an air gap is installed on the sink, remove the cap and clear any debris from inside the air gap body.
- Remove the lower dish rack, pull out the filter basket and sump cover from the tub bottom, and clean all food debris from the filter and sump area.
- Confirm the drain hose has a high drain loop attached under the counter at the height specified in your installation manual if no air gap is present.
- If the machine still will not drain, remove the lower toe kick panel and locate the pressure sensor assembly, then inspect the sensor elbow and tubing for sludge or blockage and clean or replace the sensor if contaminated.
- If draining still fails after clearing the sensor, access the drain pump from below the tub, check the impeller for debris or mechanical seizure, and replace the pump if the impeller will not turn or the pump does not run.

When to Call a Pro
If you have cleared the drain hose, filters, air gap, and disposer connection but the dishwasher still will not drain, the fault is likely in the pressure-sensing circuit or the drain pump itself. Accessing the pressure sensor and drain pump requires removing panels and working in tight spaces under the dishwasher. A technician has the tools and experience to safely test the sensor, check the pump electrically, and replace the correct assembly without damaging surrounding components. Call a pro if you are not comfortable working under the unit or if the machine continues to fault after you have cleared all visible blockages.
