GE Dishwasher Leak Detected Error – Meaning, Causes & Fix

GEDishwasherUpdated 2026-05-21

GE dishwasher error 'Leak Detected' (sometimes shown as 'Leak Detected' or a drop of water icon with an exclamation mark) is an alarm that appears when the dishwasher's water leak detection circuit has sensed water where it should not be. Modern GE dishwashers have either a mechanical float switch or electronic moisture sensors positioned in the base or near the pump that detect any accumulation of water outside of the normal wash chamber. When water is detected, the control board immediately stops the cycle and displays the leak alert to prevent further water damage to your kitchen cabinets and flooring. In most cases, a leak detected alert indicates an actual problem that requires investigation and repair, but occasionally false alerts occur from sensor malfunction.

Quick Answer

What it means

GE dishwasher's leak detection sensor has sensed water in the base pan or tub area. There is likely a real leak somewhere in the unit.

Severity

High

Can you fix it yourself?

Partial — inspecting seals and checking for visible water is safe. Hose or pump replacement requires professional service.

Call a technician when

If water is actively leaking from the dishwasher, or if the leak source is not visible after inspection.

What Does Leak Detected Mean?

GE dishwashers use a safety feature called a **leak detection system** to prevent water damage. The system includes either:

1. Float switch: A simple mechanical switch that closes an electrical circuit when water rises to a certain level in the base pan 2. Electronic moisture sensor: A more sophisticated sensor that detects moisture and signals the control board

When the leak detection system is triggered, the control board: - Immediately stops the wash cycle - Closes the water inlet valve to stop incoming water - May activate the drain pump to remove excess water - Displays the 'Leak Detected' error message

The error is a protective mechanism that prevents water from spilling out from under the dishwasher and damaging your cabinets, subfloor, and adjacent appliances.

Common sources of dishwasher leaks detected by this system: - Cracked pump or pump seal: The internal pump that circulates water has failed - Loose or deteriorated door seal: Water leaks from the door gap during wash cycles - Compromised hose connection: Water supply or drain hose is loose or kinked - Cracked tub: The internal wash chamber has developed a crack (rare on newer models) - Failed float switch or sensor: False alarm; the sensor is faulty

What Causes This Error?

Loose or corroded water inlet hose connection at the dishwasher or wall valve
Kinked or pinched drain hose restricting water flow and causing backpressure
Leaking pump seal or failed internal pump allowing water into the base
Degraded or cracked door gasket seal allowing water to escape during cycles
Door not closing fully or hinges misaligned, allowing water to drip out
Cracked or leaking spray arm or spin bearing assembly
Failed float switch or moisture sensor triggering false alarms
Cracked wash chamber or tub wall (less common on modern units)
Clogged pump or drain filter causing water to back up into the base

How to Fix Leak Detected

1
Stop using the dishwasher immediately and visually inspect for standing water. Turn off the dishwasher and do not run another cycle. Open the door fully and look inside and underneath the lower spray arm. Check the base of the tub for standing water, ice buildup, or moisture. If you see water pooled in the base, this confirms an actual leak. If the base is completely dry, the leak may be intermittent or the sensor may be faulty.
2
Check the door gasket seal. Open the dishwasher door wide and inspect the rubber gasket that runs around the door frame. Look for cracks, splits, hardening, or areas where the gasket has pulled away from the frame. Run your fingers along the gasket to feel for damage. A degraded door gasket is one of the most common sources of leaks. If the gasket looks damaged, it must be replaced.
3
Inspect the water inlet hose connection under the sink. Close the dishwasher door. Open the cabinet under your sink and locate the water inlet hose that connects from the wall shut-off valve to the back of the dishwasher. Check this connection for water drops or wet spots. Use a dry cloth to wipe the connection — if it immediately becomes wet, the hose is leaking at that point. Tighten the connection nut slightly with a wrench if loose. If tightening doesn't stop the leak, the hose or fitting has failed and must be replaced.
4
Check the drain hose connection for kinks or loose connections. Follow the drain hose where it exits the back of the dishwasher and runs under the sink to the drain. Look for kinks, pinches, or sharp bends that could restrict flow. A kinked hose can cause water to back up inside the dishwasher and trigger the leak sensor. Straighten any kinks carefully. Also ensure the drain hose is securely connected to both the dishwasher and the sink drain line.
5
Remove and clean the pump filter. Open the dishwasher door and look at the bottom of the tub. You should see a cylindrical filter or a mesh strainer at the very bottom center. Remove it by twisting counterclockwise. Rinse it thoroughly under warm running water to remove all food debris, mineral deposits, and buildup. A severely clogged filter can cause water to back up and overflow into the base. Reinstall the filter securely.
6
Run a test cycle after checks. After cleaning the filter, tightening connections, and straightening hoses, run a short wash cycle (select a 15–30 minute quick wash if available). Watch and listen for any spraying or leaking from visible areas. If the 'Leak Detected' error does not reappear and no water is visible in the base at the end of the cycle, the leak may have been resolved. If the error returns, you likely have a pump, gasket, or control board issue requiring professional service.

When to Call a Professional

A GE dishwasher 'Leak Detected' error that persists after tightening connections, straightening hoses, and cleaning the pump filter indicates a failed door gasket, failed pump, cracked tub, or faulty leak sensor. These components require professional replacement. Contact GE support at geappliances.com or 1-800-220-6899. A door gasket replacement typically costs $75–$150 including labor. Pump replacement is more costly ($200–$400). GE provides 1-year parts and labor warranty on most dishwashers.

Can You Still Use the Device?

Do not continue running the dishwasher while the 'Leak Detected' error is active. Water could accumulate in the base and potentially leak under your kitchen cabinets, causing mold and structural damage. Address the leak before resuming normal use.
