GE dishwashers
Two generations of codes, both published by GE itself.
GE dishwashers are among the few mainstream machines whose codes are fully published by the manufacturer: the classic C1-C8 drain-and-fill set on older controls, and the modern vocabulary - H2O, FTD, LEAK DETECTED, PF - on current GDT and GDF machines. Every code below comes straight from GE's own support pages.
A photo of the model label and the complete installation helps the team understand the configuration before the visit.
Top control
GDT series
Top-control built-ins - GDT550 through GDT670, plastic and stainless tubs.
Front control
GDF series
Front-control siblings sharing the same hydraulics and codes.
Dry Boost
Current feature tiers
Dry Boost, bottle jets and third racks ride on the same platform.
Legacy
GSD park
The C-code GSD generation - still washing dishes across San Diego after decades.
Start with the symptom
Common GE dishwasher problems
A symptom narrows the inspection; it does not identify the failed component. The $99 visit confirms the actual fault on the exact model before any repair is authorized.
Water
Standing water in the tub
The FTD path: hose, air gap, disposer knockout, then the pump - in GE's own order.
Cycles
Dishes wet at cycle end
Rinse aid and Dry Boost settings first, heater circuit second.
Symptom
Not cleaning like it used to
Spray arms, filter and water temperature - C6's lesson applies to every generation.
Lighting
Won't start, lights fine
Door latch and interlock - the most common no-start on GDT/GDF.
Surface
White film on glasses
San Diego hard water versus detergent and rinse-aid dosing.
Symptom
Trips the breaker
Heater and wiring isolation - taken seriously, found methodically.
Series and model numbers
GE dishwasher series we service
The generation decides the vocabulary: C-codes on the GSD era, plain-language codes on GDT/GDF - and GE documents both, which makes diagnosis a confirmation exercise.
Top control
GDT models
Model numbers
GDT670SYVFS, GDT550PYRFS
What to note
Modern vocabulary: H2O, FTD, LEAK DETECTED, PF.

What to note
The C1-C8 dialect - documented by GE to this day.
Model label
Where to find your GE model number
The rating plate is on the left side of the tub or door jamb - open the door and check the tub wall's front edge. Photograph the full model and serial. Photograph the complete label — the full model and serial identify parts and production year better than the series name alone.
Indicators and alerts
GE dishwasher alerts & indicators
For any message not shown, use the manual for the exact model rather than a generic list.
Message / alert
LEAK DETECTED or 999
What it means
GE's official leak protection tripped - water reached the base pan on Floor Protect models.
Safe check
Close the supply, protect the floor and book with priority; the cycle stays cancelled until the leak is found.
GE diagnostics
GE dishwasher error codes, decoded.
Every code above is published on GE Appliances' official support pages, including the full C1-C8 legacy table and the modern H2O/FTD/LEAK vocabulary - a level of documentation few brands match, and the reason nothing here needed a third-party guess.
Error code · H2O
Low water situation
What it commonly means
Officially documented: the machine is not getting enough water - supply or inlet side.
Safe owner step
Photograph the code and the model label, and press reset once. A single power interruption at the breaker is reasonable if safely accessible - do not repeat it.
What repair typically involves
The official checklist runs first - inlet hose, supply - then the valve and sensing; cycle-specific H2O patterns get their documented handling.
Error code · FTD / F56
Failure to drain
What it commonly means
GE's official drain-failure code on current machines.
Safe owner step
Photograph the code and the model label, and press reset once. A single power interruption at the breaker is reasonable if safely accessible - do not repeat it.
What repair typically involves
Drain hose, air gap and disposer knockout are checked per the official list, then the pump is tested directly.
Error code · LEAK DETECTED / 999
Leak protection
What it commonly means
Officially documented: a possible leak cancels the cycle on models with leak detection or Floor Protect.
Safe owner step
Photograph the code and the model label, and press reset once. A single power interruption at the breaker is reasonable if safely accessible - do not repeat it.
What repair typically involves
The source is located and repaired, the pan dried, and a verification cycle run before clearing.
Not a fault · PF
Power failure
What it commonly means
Officially documented: power to the dishwasher was interrupted.
Safe owner step
Photograph the code and the model label, and press reset once. A single power interruption at the breaker is reasonable if safely accessible - do not repeat it.
What repair typically involves
A message, not a fault - cycle restarted; repeating PF on stable power moves to the junction connection.
Error code · C1 - C8 (legacy controls)
Drain, fill and temperature set
What it commonly means
GE's official legacy set: C1-C5 pump-out and fill faults, C6 low water temperature, C7 temperature sensor circuit, C8 blocked detergent cup.
Safe owner step
Photograph the code and the model label, and press reset once. A single power interruption at the breaker is reasonable if safely accessible - do not repeat it.
What repair typically involves
Each maps to a documented subsystem - drain path, float, heater circuit, sensor - tested in the official order.
Error code · PrS
Pressure sensor signal
What it commonly means
Officially documented: the pressure sensor is sending an invalid signal.
Safe owner step
Photograph the code and the model label, and press reset once. A single power interruption at the breaker is reasonable if safely accessible - do not repeat it.
What repair typically involves
GE's own guidance is service - the harness and sensor are tested and the failed part replaced.
Any other code or behavior
Meanings vary by series and year
Why we do not guess
GE products span several control generations; the same characters can mean different things on different series. The complete model number fixes the definition.
What to capture
Photograph the full display and the model label, and note what the appliance is doing.

Preventive service and owner care
GE dishwasher maintenance
Alpha Pro provides preventive and general maintenance for GE dishwashers. The appliance design determines which procedures are accessible and appropriate.
Owner maintenance
Routine care between visits
Filter: remove and rinse the filter assembly regularly - the single most effective owner step.
Door seal: wipe the gasket and lower lip; check for debris that prevents sealing.
Loading and detergent: follow the manual for detergent and rinse aid; avoid blocking the dispenser.
Professional maintenance
Inspection follows the appliance design
A professional visit can evaluate accessible systems without assuming every procedure applies to every model.
Fill, wash, and drain performance
Circulation and drain pump condition
Heater and drying performance
Water inlet valve and float
Door latch, seal, and leak evidence

Diagnosis before parts
A straightforward three-step service process
1
Describe the symptom
Call or book with the model label, exact behavior, any displayed codes, photos, and access notes.
2
Evaluate the system
The technician examines the reported condition in context: fill, wash, drain, drying, controls, leaks, and relevant components.
3
Review the recommendation
Findings and proposed work are explained before repair proceeds. The residential diagnostic is credited toward an approved repair.
Service areas and operating context

Helpful answers
GE dishwasher service questions
Clear preparation makes a service request easier to evaluate.
Do you offer same-day GE dishwasher repair in San Diego?
Yes - same-day windows are offered across San Diego County subject to the day's schedule. Availability is confirmed for the exact address when you book.
Does the $99 residential diagnostic fee always apply?
Yes. It is non-refundable and credited toward the total repair cost if you proceed. There are no residential exceptions.
What warranty comes with a repair?
A 90-day labor warranty and a 1-year parts warranty, both starting on the date the repair is completed.
Can a symptom alone identify the failed part on a GE dishwasher?
No. A symptom narrows the search, but the diagnostic visit on the exact model confirms the actual fault before any repair is authorized.
What does H2O mean on my GE dishwasher?
GE's official low-water code. Check the supply and inlet hose per the official list; if it persists, the valve and water sensing are tested on-site.
What is FTD?
Failure to drain - GE's official code. Hose, air gap and disposer knockout are checked first, then the drain pump directly.
My display shows 999 - what happened?
On Floor Protect models that is leak protection - GE cancels the cycle. The leak is found and fixed before anything is cleared.
Where is the model number?
On the left side of the tub or door jamb - open the door and photograph the plate.
Do you still service the old GSD machines?
Yes - GE still documents their C1-C8 codes, parts remain available, and the platform is famously repairable.
