Quick Assessment
Answer to continue safely
Is it safe to keep using?
No. Operating with standing water risks spilling during door opening and can damage the pump motor if run dry. Resolve the drain fault before resuming normal use.
Can I reset the code?
Yes. Press Cancel/Drain and allow the dishwasher to attempt a full drain cycle. If the tub empties, the code clears automatically. A hard reset (circuit breaker off for 1 minute) also clears the fault code from memory.
When to stop immediately?
Stop if you notice: Water is overflowing or pooling on the kitchen floor, The drain pump makes a loud grinding or screeching noise.
Symptoms You May Notice
Water remains in the tub
After the cycle ends or pauses, standing water is visible at the bottom of the dishwasher tub, indicating drainage did not complete.
C1 displayed on the control panel
The alphanumeric display shows "C1" and the cycle halts. On older LED-only models, the Start or Clean light may blink repeatedly.
Drain pump runs but water level does not drop
You can hear the pump motor humming, yet water stays at the same level — suggesting a blockage or pump restriction rather than a dead motor.
Cycle stops mid-wash
The dishwasher interrupts a wash or rinse phase and locks out further operation until the fault is cleared.
Possible Causes
Clogged drain filter or sump
Food debris and grease accumulating in the coarse and fine filters restricts water flow to the drain pump, causing the pump to time out.
DIY PossibleKinked or obstructed drain hose
A bent or partially blocked drain hose between the dishwasher and the sink drain / garbage disposal prevents water from escaping quickly enough.
DIY PossibleFaulty drain pump or pump impeller
A worn impeller, seized pump motor, or damaged pump housing reduces pumping capacity. Replacement requires disassembly of the lower wash arm assembly.
Requires ProfessionalSafe Checks You Can Do
-
1
Clean the drain filter assembly
Remove the lower rack. Turn the cylindrical filter counter-clockwise and lift out both the coarse mesh and ultra-fine filters. Rinse under warm running water and scrub gently with a soft brush. Reinstall and run a short cycle.
GE recommends cleaning the filter monthly. A clogged filter is the most common cause of C1 on GDT and GDF models.

2
Inspect the drain hose for kinks
Pull the dishwasher slightly forward (after disconnecting power) and trace the drain hose from the pump to the sink drain or garbage disposal. Straighten any kinks and ensure the high-loop or air-gap is intact.
If connected to a new garbage disposal, confirm the knock-out plug inside the disposal inlet was removed.

3
Reset the control board
Press Cancel/Drain to run a manual drain cycle. If water clears, cancel again and restart a normal wash. Alternatively, turn off the circuit breaker for 1 minute, restore power, and run a test cycle.
If C1 returns immediately after the reset without any standing water, the drain pump itself likely needs professional evaluation.
When to Call a Professional
Contact a qualified technician if:
- Filter and drain hose are clean but C1 persists after multiple resets
- Drain pump is audibly straining or completely silent during the drain phase
- Water damage or mold is visible under the dishwasher base
