What This Error Means
F23 on most GE Profile dishwashers means: leak/overflow detected in the base pan.
The control board thinks there’s water sitting in the bottom tray under the tub, so it locks the machine to avoid a kitchen flood.
Note: GE reuses code numbers across some models. If your tech sheet behind the toe-kick says something slightly different for F23, treat it as a water-leak / safety shutdown problem either way.
Official Fix
Do it the way the manual wants, step by step:
- Kill power and water first.
Flip the dishwasher breaker off. Shut the under-sink water valve. Don’t skip this; you’re dealing with water around electrics. - Pull the dishwasher out of the cabinet.
- Open the door and remove the mounting screws at the top/side of the frame.
- Gently slide the unit out a foot or two so you can see underneath.
- Check the base pan for standing water.
- Use a flashlight at the front bottom and from the side.
- If you see a puddle in the plastic/metal tray, that’s what tripped F23.
- Sponge or towel out all the water so the float / leak switch drops back down.
- Find where it’s leaking.
Common leak spots:- Door gasket – torn, flattened, or split corners.
- Bottom door seal – drips from the very bottom of the door during a wash.
- Inlet valve area – drip where the water line connects under the left/right front.
- Drain hose or pump – wet trail at the side or back during drain.
- Cracked plastic parts – sump, diverter, or internal hoses.
- Fix or replace the bad part.
- Loose clamp or fitting: tighten it.
- Cracked hose: replace the hose.
- Bad door gasket: replace the gasket and clean the door sealing surface.
- Leaking inlet valve / pump body: replace the whole valve or pump assembly.
- Reassemble and test for leaks.
- Slide the dishwasher back most of the way, but leave the toe-kick off so you can watch underneath.
- Turn the breaker and water back on.
- Run a quick wash and watch the base with a flashlight for any fresh drips.
- If the base pan stays dry and the float isn’t lifted, F23 should clear after a power cycle or the first normal run.
- If F23 comes back immediately with a dry base pan:
The leak/float switch or its wiring may be faulty. At that point, the manual’s answer is: call for service or replace the sensor assembly.
The Technician’s Trick
Here’s the real-world move techs use when the pan is wet but the leak is minor or intermittent.
- Tip-and-drain reset.
- With power and water off, slide the dishwasher out.
- Put a towel in front. Carefully tip the machine forward about 30–45°.
- Let any water in the base pan pour out the front onto towels or a shallow tray.
- Stand it back up and dry the float / leak switch area with a fan or hair dryer on cool.
- Hard reset the control.
- Turn the breaker off for 5–10 minutes.
- Flip it back on and try a short cycle.
- If F23 is gone and no new water shows up underneath, you likely tripped the sensor from a one-time overflow (too much soap, door not fully shut, etc.).
- But don’t ignore a repeat F23.
If the code keeps returning or you see fresh water in the pan, you’ve got a real leak. Then you’re back to the official fix: find the source and change the part, not just dry the sensor.
Is It Worth Fixing? (The Financial Verdict)
- ✅ Fix: Machine under ~8–10 years old, leak is clearly from a gasket, hose, clamp, or inlet valve, and parts are under about $150.
- ⚠️ Debatable: Tub or sump is cracked, or multiple wet components (pump + hoses + valve) and total repair cost is creeping over 40–50% of a new dishwasher.
- ❌ Replace: Older than ~12 years, heavy rust or other issues already bugging you, or a quoted repair approaches the price of a mid-range new GE/other brand unit.
