GE Dishwasher FTD — What It Means & How to Fix It
Also shown as F56 on some models.
FTD — shown as F56 on some models — means the dishwasher failed to drain, and the three things to check are the same external trio: the drain hose, the countertop air gap, and the garbage disposer.
What this code means
FTD stands for failure to drain: at the end of the cycle the dishwasher couldn't clear its water. GE points to the external drain path first — the drain hose, the countertop air gap, and the disposer the hose connects to. On some control versions the same fault is logged as F56. Because the water sits in the tub floor, you will usually see standing water along with the message.
FTD and F56 are the same failure-to-drain fault on different GE control versions. If your model instead shows a C-series drain code (C1, C2, or C3), those cover the same territory with GE's graduated severity — check your model's fault list.
Most likely causes
| Cause | How likely | DIY-fixable? |
|---|---|---|
| Garbage disposer not run, or its outlet blocked | Common | Yes — run the disposer |
| Countertop air gap clogged | Common | Yes — unscrew cap, rinse |
| Drain hose kinked or blocked | Common | Partly — visible sections |
| Disposer knockout plug never removed (new installs) | Common after installs | Yes — hammer + screwdriver |
| Drain pump failed | Less common | No — technician job |
What you can try yourself
- Run your garbage disposer with water for ten seconds — a dishwasher that drains through a disposer can't clear water the disposer is holding.
- Unscrew the air gap cover on the countertop and rinse out any sludge inside; a clogged air gap stops the drain.
- Trace the drain hose under the sink, lift out any kink or crush, and check the junction where it meets the disposer or drain tee.
- If a disposer was recently installed, unplug it and confirm the dishwasher inlet's knockout plug was punched out — a sealed plug blocks draining entirely.
- Restore power and run a short cycle, watching that the tub empties within a minute or two.
When to call a technician
- FTD persists with the disposer, air gap, and hose all confirmed clear — the drain pump is the likely failure.
- The pump buzzes or grinds at drain time but no water leaves.
- Water backs up into the sink as the dishwasher drains, which points to household plumbing rather than the dishwasher.
Typical professional repair cost: A cleared drain path costs nothing. A drain pump replacement typically runs $150–$300 with labor.
Frequently asked questions
What does FTD mean on a GE dishwasher?
FTD is short for failure to drain — the dishwasher couldn't pump out its water by the end of the cycle, and you will usually see standing water in the tub. Some models log the same fault as F56. The checks are the disposer, the air gap, and the drain hose.
Is FTD the same as F56?
Yes — they are the same failure-to-drain fault, just shown differently depending on the control version. Whichever your machine displays, work through the external drain path: run the disposer, clear the air gap, and check the hose.
My new disposer was just installed and now FTD appears — why?
Garbage disposers ship with a solid knockout plug over the dishwasher inlet, and it is easy to forget to remove it. With the disposer unplugged, tap the plug into the grinding chamber with a screwdriver and pull the plastic disc out — the timing right after installation is the giveaway.
Related GE codes
- GE Dishwasher C1 Your GE dishwasher is draining, but too slowly for the control's liking — the water path is partly restricted, usually at the air gap, the drain hose, or a disposer that hasn't been run.
- GE Dishwasher C2 Draining ran well past the time GE allows — about seven minutes — pointing to a heavier blockage than the milder C1, though the things to check are the same trio.
- GE Dishwasher C3 The dishwasher didn't drain at all, and GE's first move for C3 is a brief power reset — if water still won't leave afterward, the drain path or pump needs attention.
- GE Dishwasher C4 C4 means the dishwasher refilled twice after a power interruption, which usually traces to a stuck overfill float or a clogged sump rather than anything electrical.
