Can a clogged drain cause an FTD error?
Yes. On the GE GDT580SMF2ES dishwasher, a clogged drain path can trigger an FTD error because the dishwasher needs to pump out old water correctly before it can sense the tub is ready to fill and continue the cycle.
- Cancel the cycle and let the dishwasher attempt to drain.
- Check for standing water in the bottom of the tub.
- Clean the air gap (if your installation has one).
- If the dishwasher drains into a disposer, run the disposer to clear it.
- Confirm the kitchen sink drains normally; a slow sink often points to a plumbing restriction.
- Verify the drain hose routing is correct (high loop or air gap) and not kinked.
A drain restriction is not always inside the dishwasher. A low drain hose, a kink, or an overly long hose can slow draining and confuse the fill and drain sensing.
| Item | What “good” looks like | What causes trouble |
|---|---|---|
| Drain hose routing | High drain loop or air gap | Low loop, sagging hose, kinks |
| Air gap (if used) | Clear cap and passage | Debris buildup blocks flow |
| Hose length | Within installation limits | Excess length reduces drain performance |
For the correct routing and hose length limits, follow the installation guide.
If the hose and air gap are clear but the dishwasher still will not pump out, the issue is often in the drain system (blockage at the pump area, or a failed drain component). A common electrical cause is a control issue, but we always rule out clogs first.
Parts that can be involved in drain and fill sensing problems include:
- Dishwasher drain hose WD24X10062 (kinked, restricted, or leaking)
- Float and overfill protection components (if stuck by debris)
- Drain pump area (obstructed by food debris or broken glass)
FTD is frequently a “can’t drain or can’t confirm empty” situation. Clearing the drain path prevents repeat errors, protects the circulation system, and helps the dishwasher start the next fill cycle normally.

What is the most common problem with GE dishwashers?
On the GE GDT580SMF2ES dishwasher, the most common customer-reported issue is the dishwasher not starting or stopping mid-cycle, often tied to the door not fully latching or a cycle interruption. We focus first on door-latch engagement, Start behavior, and basic power checks.
- Press Start and fully close the door; many GE models require Start to be pressed and the door to be closed to begin.
- If the Start status light is flashing, the door was opened or the cycle was interrupted; press Start and close the door.
- If it beeps once every minute, the door is being detected as open during operation; press Start and close the door.
- Reset power by turning the dishwasher circuit off for 1 minute, then back on.
- Check for a tripped breaker or blown house fuse.
If the door is closing but the dishwasher still will not run, these parts are frequent suspects on this model:
| Symptom | Common cause | Example part for GDT580SMF2ES |
|---|---|---|
| Door closes but unit won’t run | Door latch not locking | GE dishwasher door latch lock WD21X10490 |
| Random stops, dead panel, odd behavior | Control not responding | WD21X22276 machine control (board) |
| Buttons light but cycles do not begin | User interface issue | WD21X22177 user interface |
Other common GE dishwasher complaints are poor cleaning, not draining, or not drying. These are usually maintenance or water-flow related:
- Clean the filters regularly (many owners do this about every other month, more often with heavy use).
- Check spray arms for clogs and free spinning.
- Use the right amount of quality detergent and add rinse aid for drying.
For model-specific operating steps and troubleshooting charts, use the GDT580SMF2ES owner’s manual. For fault displays and diagnostics, use our GE electronic dishwasher error codes guide.
A dishwasher that does not start is often a simple door-latch or cycle-interruption condition. Fixing that first prevents unnecessary part replacement and gets your GE GDT580SMF2ES back to washing normally.

What is the error code F128 on a GE dishwasher?
On the GE dishwasher model GDT580SMF2ES, “F128” is not a standard consumer-facing error code; it typically shows up when the control is in a diagnostic/service display or when the UI is misreading a key sequence. Use the GDT580SMF2ES owner's manual to confirm what your display is actually indicating and how to exit special modes.
- Cancel the cycle (press Start/Reset per the control panel instructions), then close the door.
- Turn power off at the breaker for 1 minute, then restore power to reboot the control.
- Start a Normal cycle and watch for a repeatable message (letters like “LEAK DETECTED” or a beeping pattern are more actionable than “F128”).
- If the dishwasher beeps every minute, press Start and close the door fully.
- If the display changes to a different code/message, troubleshoot that new code instead.
| What you see | What it usually means | Best next step |
|---|---|---|
| “F128” appears briefly, then clears | Glitch or mode exit | Power reset; run a cycle |
| “F128” repeats and buttons act odd | User interface/keypad issue | Inspect console for stuck keys; consider UI diagnosis |
| “F128” appears with no wash action | Control not starting a cycle | Check door closure and latch engagement |
If “F128” returns after a power reset and the dishwasher will not start or keys do not respond normally, these parts are commonly involved:
- User interface WD21X22177 (touchpad/display inputs)
- Machine control WD21X22276 (electronic control board)
- GE dishwasher door latch lock WD21X10490 (door must latch for operation)
A non-standard code often means the dishwasher is not in normal operating mode or the controls are not communicating correctly. Resetting and confirming the exact message prevents replacing parts based on a misleading display.

How do I clear the error code on my GE dishwasher?
To clear an error code on your GE GDT580SMF2ES dishwasher, cancel the current cycle and restart the control. Press and hold Start for 3 seconds, then close the door so the dishwasher drains and the cycle ends; then start a new cycle (see the GDT580SMF2ES owner's manual).
- Press and hold Start for 3 seconds.
- Close the door to allow the dishwasher to drain and end the cycle.
- When draining stops, open the door.
- Select your desired wash cycle and options.
- Press Start, then close the door to begin.
An error code often comes back because the dishwasher is still detecting the underlying problem.
- Beeping once every minute: the door was left open during operation; press Start and close the door.
- “LEAK DETECTED”: the dishwasher can cancel the cycle when leak detection is triggered; check for water under the unit and obvious leaks.
- Won’t start: confirm the door is latching firmly and the strike is aligned.
| Symptom | What to inspect | Example part for GDT580SMF2ES |
|---|---|---|
| Won’t start, door won’t latch | Latch/lock assembly | GE dishwasher door latch lock WD21X10490 |
| Door closes but won’t catch | Latch strike | Dishwasher door latch strike WD13X10071 |
| Random stopping or no response | User interface or control | Machine control WD21X22276 |
Canceling and restarting clears the active cycle state so you can run the dishwasher again. If the same code keeps returning, fixing the cause (door latch, leak detection, or control issue) prevents repeat shutdowns and incomplete draining.
