Step-by-Step DIY Fix Guide
- SAFETY: Disconnect power and turn off the water supply valve under the sink immediately.
- Do not restart the dishwasher — water in the base will continue to accumulate.
- Carefully pull the dishwasher forward slightly to inspect the floor beneath for standing water.
- Inspect the door gasket around the entire door perimeter for tears, gaps, or displaced sections.
- Check that you are using dishwasher-specific detergent (not dish soap or laundry detergent) — wrong detergent causes extreme sudsing that overflows into the base.
- Contact GE Appliances Service at 1-800-432-2737 to schedule a technician inspection.
If it's still not draining
- If the drain path looks clear but the code returns, the issue is more likely in the pump path or another less accessible restriction.
- If normal household water flow looks good but the code returns, the inlet-valve or fill-sensing path becomes more likely.
- If the door closes normally but the warning keeps returning, the latch or switch path becomes more likely than a simple alignment issue.
What This Error Means
Error LEAK on your GE Appliances dishwasher means: The dishwasher's leak detector has sensed moisture in the base of the appliance, indicating a water leak somewhere in the machine. The dishwasher has stopped the cycle and activated the drain pump to remove water from the base. Also displayed as LEAK DETECTED on some GE models. The dishwasher's self-diagnostic system detected this condition and paused the current cycle.
The most frequent cause is door gasket worn, torn, or displaced — water leaking around the door seal. Work through the causes and fix steps below in order — most GE dishwasher errors can be resolved without a service call.
GE's official guidance classifies LEAK as a technician-only fault. A 60-second power reset is the only DIY step — if the code returns, contact GE Appliances Service at 1-800-432-2737.
Most fill errors trace back to the water supply valve under the sink — it is often partially closed after the dishwasher has been moved or the sink plumbing has been serviced. Confirm the valve is fully open before investigating anything further.
Most Likely Cause by Symptom
The GE Appliances dishwasher may stop, pause, or refuse to complete the cycle normally.
Likely cause: Door gasket worn, torn, or displaced — water leaking around the door seal
Check first: SAFETY: Disconnect power and turn off the water supply valve under the sink immediately.
Water may remain inside the appliance instead of clearing normally.
Likely cause: Spray arm cracked or a spray arm hub seal leaking — water escaping before it reaches dishes
Check first: Do not restart the dishwasher — water in the base will continue to accumulate.
You may notice leaking, moisture, or water where it should not be.
Likely cause: Tub crack or a deteriorated tub-to-pump connection seal
Check first: Carefully pull the dishwasher forward slightly to inspect the floor beneath for standing water.
Common Causes
- Door gasket worn, torn, or displaced — water leaking around the door seal
- Spray arm cracked or a spray arm hub seal leaking — water escaping before it reaches dishes
- Tub crack or a deteriorated tub-to-pump connection seal
- Inlet hose or internal water valve connection leaking inside the cabinet
- Excessive suds from too much or wrong type of detergent overflowing into the base
What Not to Do
- Do not restart the dishwasher with LEAK displayed — continued operation will increase the volume of water in the base and can cause floor and cabinet damage
- Do not use hand dish soap or laundry detergent in a dishwasher under any circumstances

Parts, Tools and Service Options
Service option
GE Appliances service visit if the warning returns after the basic checks are complete.
Manual and model check
Check your exact model and manual before ordering any GE Appliances dishwasher parts.
Common parts
- Door gasket/seal if worn or torn ($15–$50)
- Spray arm assembly if cracked ($20–$60)
- Inlet valve if leaking internally ($25–$60)
- Tub seal kit if the tub-to-sump seal is leaking ($20–$50)
This section stays service-first because the page points more strongly toward support or professional repair than a routine parts purchase.
When Not to Keep Troubleshooting
Immediately — LEAK requires professional diagnosis before the dishwasher is used again
How to Prevent It Recurring
- Inspect the door gasket annually — press your finger along the entire seal looking for cracks, hardening, or loose sections
- Always use automatic dishwasher detergent — hand dish soap creates extreme foam and rapidly triggers the leak sensor
Related Error Codes
C4
After a power interruption, the dishwasher filled twice without completing a drain. This indicates either the float switch (overflow protection) is stuck in the raised position, or a blocked drain is preventing water from clearing between fills.
C3
GE dishwasher error C3 usually means the machine did not drain water from the tub during the normal drain phase.
