The short answer
FTD or F56 is the blunt version of a drain fault: the control asked for a pump-out and the tub did not empty. Expect standing water when you open the door. Unlike a slow-drain code this one means the path is closed rather than narrowed, so there is usually a single blockage to find, and it is often within reach of a hand and a torch.
GE dishwasher code as the manufacturer publishes it
Reference| Code | Meaning |
|---|---|
| FTD or F56 | Failure to drain. |
What you observe alongside the code
- A tub full of water at the end of the cycle — The defining symptom.
- No drain sound at all when the pump should run — Points at the pump or its supply rather than at a blockage.
- A loud buzz or hum instead of the usual drain note — A pump trying to turn against something jammed.
- A smell after a day or two — Standing wash water, not a separate fault.
What triggers it, most likely first
- A hard object across the drain pump inlet — First: a fruit stone, a bone chip or a shard of glass closes the inlet completely, which is exactly what this code reports.
- A blocked or crushed drain hose — Second: a hose flattened where the machine was pushed back into its opening drains nothing at all.
- A seized or electrically dead drain pump — Third: no drain sound at all is the tell, and it separates this from every blockage above.
- A blocked standpipe or air gap — Last: it closes the path outside the machine, and the sink usually complains first.
Check in this order, and why
- Listen during a drain attempt before touching anything — Silence, hum and normal note each send you somewhere different.
- Bail the tub and clear the filter and sump by hand — The blockage is in reach from inside the tub more often than not.
- Feel along the drain hose behind the machine for a crush — Free, and it catches the installation-damage cases.
- Pour water down the standpipe last — Tests the house side once the machine side is clean.
Clearing the code, then the owner-safe checks
- Bail and sponge the tub dry — A jug and a sponge. Everything after this is easier.
Tools: jug, spongeAbout 20 min
- Remove the filter and clear the sump and pump inlet by hand — Gloves on: glass and bone chips are what you are feeling for.
Tools: gloves, flashlightAbout 20 min
- Straighten or replace a crushed section of drain hose — A hose that has taken a permanent flat will not recover by being repositioned.
Tools: pliers, flashlightAbout 30 min
- STOP HERE if the pump is silent with the sump clear — A dead pump or its wiring is under the tub and is a service call.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. On a built-in dishwasher the supply is not switched at the door, so the breaker is the only reliable off. Leave the door latch switch wired as it is: it stops the pump and the heater the moment the door opens. Bail before you go under the machine, and never reach blind into a sump you have not lit.
When this code is a service call
Call when the sump and inlet are clear, the hose is sound, and the pump makes no sound during a drain attempt — that is the pump or its circuit under the tub. Call promptly either way if standing water has been in the tub for more than a day or two with a full load in it, because the tub is the smallest part of that problem.

Which model lines this reading applies to
This reading of FTD or F56 applies to current GE and GE Profile built-in dishwashers with a digital display or a lit status row, the platform on which the manufacturer publishes it. A timer-driven machine with no display never shows it, and a Monogram or Hotpoint-badged unit can use the same characters for a different fault. The lettered and numbered forms of this fault belong to different display generations and mean the same thing. Where a model-specific page exists for your unit it is linked above and is the more specific answer: part-level detail differs by family and belongs there.
