Find Your GE Dishwasher Error Code and What to Check Next
Is your GE dishwasher displaying H2O, FTD, F56, C1, 999 or LEAK DETECTED? These messages can indicate water-supply problems, slow drainage, a possible leak or a sensor-related fault.
Use this guide to identify the code, understand what it commonly means and decide which checks are safe to perform before requesting professional service.
How to Read GE Dishwasher Fault Codes
GE dishwashers use fault and function codes to report conditions detected during a wash cycle. The same dishwasher symptom can have several causes, and not every GE model uses the same set of codes.
Write down the complete code and the model number before resetting the dishwasher. GE, GE Profile and Café dishwasher models may use different displays and controls. The exact meaning should always be checked against the model’s documentation.

GE Dishwasher H2O, C5 and C6 Errors
These codes involve water filling, water availability or incoming water temperature. They do not all indicate a failed inlet valve.
GE Dishwasher H2O Error — Low Water
H2O indicates that the dishwasher has detected an insufficient-water condition.
What to check:
- Confirm the water supply valve is open.
- Check the accessible inlet hose for kinks.
- Note which cycle produces the error.
- If H2O appears only during 1-Hour Wash, GE recommends service; other cycles may still operate.
- If the code continues, the inlet system or controls may require testing.
GE Dishwasher C5 — Pump-Out Time Too Short
GE identifies C5 as a pump-out time that is shorter than expected. The manufacturer’s initial checks focus on water availability and the float.
- Make sure the water supply is turned on.
- Retry the cycle if there is no active leak.
- Inspect the accessible float cover for sticking, if your model has one.
- Arrange service if the condition persists.
GE Dishwasher C6 — Water Too Cold
C6 indicates that the incoming water temperature is below the required level.
- GE recommends incoming water around 120°F for applicable models.
- Run the nearby hot-water faucet before starting the dishwasher.
- Check the model’s hot-water requirements.
- Do not raise household water-heater temperatures without considering scalding risk.
GE Dishwasher C7 — Temperature Sensor Circuit
C7 indicates a problem with the water-temperature sensor circuit.
- Follow the manufacturer’s reset instructions.
- If C7 returns, the sensor circuit and related wiring require diagnosis.
- Do not replace the sensor without confirming the cause.
GE Dishwasher FTD, F56, C1, C2 and C3 Errors
Standing water, a cycle that stops before completion or a drain pump that runs longer than expected can accompany these codes. Start with accessible drain components before assuming the pump has failed.
GE Dishwasher FTD or F56 — Failure to Drain
FTD and F56 indicate that the dishwasher has not drained as expected.
- Inspect the filter and accessible drain area.
- Check the drain hose for visible kinks.
- Check the sink air gap, if installed.
- Confirm the connected sink or disposal drain is not blocked.
- Persistent faults may involve the drain pump or electrical system.
GE Dishwasher C1 — Drain Time Over 2 Minutes
GE identifies C1 when the drain pump-out process exceeds two minutes.
- Clean the sink air gap, where applicable.
- Inspect the drain hose for restriction or improper positioning.
- Check the connected sink drain.
- Request diagnosis if drainage remains slow.
GE Dishwasher C2 — Drain Time Over 7 Minutes
C2 indicates the total pump-out cycle has exceeded seven minutes.
- Check for standing water after the cycle.
- Inspect accessible filters and the drain connection.
- Use the model’s RESET procedure to silence the alert.
- Recurring C2 errors warrant a drainage-system inspection.
GE Dishwasher C3 — Dishwasher Will Not Drain
C3 means the dishwasher has detected a failure to drain.
- Check for an obvious external drain restriction.
- GE suggests a breaker reset of approximately 30 seconds on applicable models.
- If the code returns, arrange professional diagnosis.

GE Dishwasher LEAK DETECTED, 999 and C4
These codes deserve special attention because some GE dishwashers use protective systems to detect unwanted water. The correct response depends on the model and whether water is visibly leaking.
Possible Leak Detected
On models equipped with leak detection, this message indicates a possible leak and may cancel the wash cycle.
Stop using the dishwasher, check for visible water and arrange service. Do not repeatedly clear the warning without investigating the cause.
GE Dishwasher 999 — Leak Alert or Reset Condition
On models equipped with Floor Protect with Alert, 999 can indicate a possible leak. On other GE dishwashers, it may indicate that the control needs to be reset.
Check your model’s documentation. If it has leak protection, treat 999 as a possible leak and request service.
GE Dishwasher C4 — Unexpected Fill Condition
GE associates C4 with repeated filling after a power failure, a stuck or failed float switch, or a clogged drain or sump.
Check the accessible float cover and sump for debris with power disconnected. If the code persists, further diagnosis is needed.
Signs That Require Prompt Attention
Water on the floor, damp cabinetry, repeated leak warnings or unexplained pump operation may indicate a problem that should be investigated before another wash cycle.
Turn off the water supply and power when safe. Avoid touching wet electrical connections.
Other GE Dishwasher Codes and Display Messages
Not every message indicates a broken part. Some displays show operating modes or conditions that can be corrected without a repair.
Pressure Sensor Signal Problem
PrS indicates an invalid pressure-sensor signal. The dishwasher may fail to start or cancel a cycle. GE identifies the sensor or wiring harness as possible causes. Professional diagnosis is recommended.
Detergent Cup Blocked
C8 indicates that the detergent dispenser cannot open fully. Check whether a utensil, large pan or rack item is blocking the dispenser door.
Power Failure
PF indicates an interruption in power. On applicable models, select the desired wash cycle and start again after confirming normal power has been restored.
Detergent Cup Not Closed
The detergent cup may not be properly latched. Close it and remove anything preventing normal operation. Check the manual if the message persists.
Delay Start
A number followed by H can indicate a Delay Start setting, not a fault. Check the selected cycle and timer before arranging repair.
What to Check Before Scheduling GE Dishwasher Repair
These steps help identify common external problems without opening electrical panels or dismantling the dishwasher.
Record the Complete Code and Model
Photograph the display and the model label. Note whether the error occurs at startup, during filling, washing or draining.
Check for Visible Water
Inspect the floor and cabinet edges for moisture. If an active leak is present, stop the dishwasher and isolate water and power when safe.
Check the Water Supply
Confirm the supply valve is open and that accessible hoses are not kinked. This is particularly useful for H2O errors.
Inspect the Filter and Drain Connection
With the dishwasher powered off, clean accessible filters according to the manual. Check the sink drain, air gap and visible drain hose.
Check Loading and the Detergent Dispenser
Confirm dishes and utensils do not obstruct the detergent cup, spray arms or door.
Reset Only When Appropriate
For certain codes, GE recommends a brief power reset. Follow the procedure for your model. Do not reset and restart an actively leaking dishwasher.
Arrange Diagnosis if the Code Returns
Persistent drainage, filling, temperature-sensor or leak faults may require testing of pumps, valves, sensors, wiring or electronic controls.
When Does a GE Dishwasher Error Need a Technician?
Repeated FTD, F56 or C3
If the drain path is clear but the dishwasher still cannot drain, the pump, wiring and controls may need testing.
Persistent H2O or PrS
Normal household water supply with recurring fill or sensor errors suggests the need for component-level diagnosis.
LEAK DETECTED or Leak-Related 999
Leak protection warnings require inspection before normal operation resumes.
Repeated Errors After Safe Checks
A code that returns after the recommended initial checks should not be treated as proof that one specific part has failed.
