GE CDT805P2N3S1 dishwasher Parts

Your GE Nautilus dishwasher’s age is determined from its serial number, not the model name. On GE dishwashers like model CDT805P2N3S1, the model and serial label is on the tub wall just inside the door; use the serial’s date code to identify the manufacture month and year (then you can calculate its age). See the CDT805P2N3S1 owner’s manual for the exact label location.

How to find the serial number on your dishwasher

We use the serial number because it contains the production date code.

• Open the dishwasher door fully.
• Look on the tub wall just inside the door (not on the outer door panel).
• Write down both the model number and the full serial number.
• Take a clear photo of the label for reference.
• Keep the information with your paperwork for future parts lookups.

How to decode the manufacture date (what to look for)

GE serial numbers typically include a date code at the beginning of the serial number.

• The first letter commonly indicates the month.
• The second letter commonly indicates the year.
• The remaining characters identify the production sequence.

Quick example (format only)

Serial starts with	What it means	What you do next
2 letters (example: ABxxxx)	Month code + year code	Convert to a calendar month and year
Longer string after	Factory/sequence info	Ignore for age calculation

Why it matters

Knowing the manufacture date helps us match the correct GE dishwasher parts and revisions, especially for electrical and leak-related components such as the GE dishwasher door latch lock WD21X10490, the dishwasher drain pump WD19X25461, or the GE dishwasher pressure sensor WD21X25468. It also helps when comparing cycle behavior and troubleshooting symptoms against the correct documentation.

On the GE dishwasher model CDT805P2N3S1, the most reliable “hard reset” is a power reset: turn the dishwasher off at the breaker (or unplug it if it has a cord), wait 2 to 5 minutes, then restore power. If the issue is a stuck cycle, cancel it by holding START for 3 seconds.

Fast reset options (try in this order)

• Cancel/Drain reset (in-cycle): Press and hold START for 3 seconds, then close the door; the unit drains and the cycle ends.
• Start sequence reset (won’t start): Press START and close the door within 4 seconds.
• Power reset (true hard reset): Turn OFF power at the breaker for 2 to 5 minutes, then turn it back ON.
• Door reset (paused cycle): Open the door to pause, then press START and close within 4 seconds.

What “reset” fixes (and what it doesn’t)

A reset helps when the control is confused by an interrupted cycle, a door that was opened mid-cycle, or a keypad sequence issue. It will not fix a mechanical failure like a bad drain pump, heater, or door latch.

Symptom	Best reset to try	What to check next
Stuck mid-cycle	Cancel/Drain (hold START 3 sec)	Drain hose routing, disposer plug removed, air gap clog
Has power but won’t run	Start sequence reset	Door fully latched, control lock, breaker/wall switch
Beeps every minute	Door reset	Door left open during operation
Random glitches after outage	Power reset	Loose wiring at junction box, moisture in control area

Why it matters

Using the correct reset method prevents unnecessary part replacement and helps you quickly separate a control-state problem from a real failure (like a latch that won’t engage or a drain system restriction).

Parts that commonly relate to “won’t start” or “won’t run”

If resets don’t help, these model-matched parts are common suspects:

• Door not latching: GE dishwasher door latch lock WD21X10490
• Unit won’t drain after cancel: dishwasher drain pump WD19X25461
• Fill or wash issues that stop a cycle: GE dishwasher pressure sensor WD21X25468

For more troubleshooting and ordering, use the parts list for model CDT805P2N3S1 on this page, or search by model at Sears PartsDirect. For exact button sequences and indicator behavior, follow the owner's manual and the installation guide (power and wet-test steps).

Yes. On the GE dishwasher model CDT805P2N3S1, an FTD (fail to drain) condition is commonly caused by a clogged drain path, such as a blocked air gap, a kinked drain hose, or a disposer connection that is still plugged. Use the CDT805P2N3S1 installation guide drain-check steps to confirm the drain path is clear.

What to check first (fast drain-path checklist)

• Cancel the cycle by pressing and holding START for 3 seconds; the dishwasher should begin draining.
• Open the door and confirm whether water is still standing in the tub.
• Check the air gap (if your setup has one) and clean it.
• Confirm the disposer inlet plug was removed (common after a new install).
• Inspect the drain hose for kinks or crushing behind or under the dishwasher.
• If the dishwasher drains into a disposer, run the disposer and make sure the sink drains normally.

Why a clog triggers an FTD

When the drain path is restricted, the drain pump cannot move water out fast enough. The dishwasher senses that water is not leaving the tub as expected and flags a drain failure.

Common clog points

Clog location	What you’ll notice	What usually fixes it
Air gap	Slow drain, water backing up at sink	Clean the air gap cap and passage
Disposer connection	Dishwasher never drains after install	Remove disposer plug, clear inlet
Drain hose	Intermittent or no drain	Straighten hose, correct routing
Filter area	Poor cleaning plus standing water	Clean filters per CDT805P2N3S1 owner’s manual

Parts that can be involved if the drain path is clear

If the hose, air gap, and disposer connection are clear but the unit still will not drain, the issue often shifts from “clog” to a component problem.

• Drain pump: dishwasher drain pump WD19X25461
• Drain hose (if damaged or internally blocked): dishwasher drain hose WD24X10062
• Pressure sensing (can affect how the unit interprets water level): GE dishwasher pressure sensor WD21X25468

Why it matters

A true drain restriction can leave dirty water in the sump, reduce wash performance, and cause odors. Clearing the drain path first prevents unnecessary part replacement and gets the dishwasher back to normal cycle operation.

For the GE CDT805P2N3S1 dishwasher, the most common problems we see are “won’t start” and “won’t drain.” In many cases, the fix is basic: confirm the door fully latches, the control isn’t locked, and the filter, drain hose, and sink/disposer connection are clear (see the CDT805P2N3S1 owner's manual).

Most common symptoms and what to check first

• Dishwasher won’t run: make sure the door is firmly closed and latched.
• Has power but won’t start: check for control lock and try a proper Start/Cancel reset.
• Won’t fill: confirm the water valve under the sink is on; check that the flood float is not stuck.
• Won’t drain: clear the filter area, check the drain hose routing, and confirm the disposer inlet plug is removed (new disposer installs).
• Suds or leaks: use only automatic dishwasher detergent; hand dish soap causes heavy suds and can push foam out of vents.

Parts that commonly solve these problems

If the basic checks point to a failed component, these are common repair parts for this model:

Symptom	Likely area	Example part for CDT805P2N3S1
Won’t drain, standing water	Drain system	Dishwasher drain pump WD19X25461
Intermittent fill or fill errors	Water level sensing	GE dishwasher pressure sensor WD21X25468
Won’t start, door won’t “click” shut	Door latch	GE dishwasher door latch lock WD21X10490
Poor drying	Heating circuit	Element heat WD05X35098

Why it matters

Start and drain issues are the two problems that stop a cycle completely. Catching a simple cause (door not latched, control lock, stuck float, clogged drain path) prevents unnecessary part replacement and helps protect the wash pump and control from repeated failed starts.

Helpful model-specific references

• Use the troubleshooting steps and detergent guidance in the CDT805P2N3S1 owner's manual.
• For installation-related causes of draining and filling problems (hose routing, anchoring, water supply), follow the installation guide.
• For code-based troubleshooting, use GE electronic dishwasher error codes.

Yes; repairing your GE CDT805P2N3S1 dishwasher is worth it when the failure is limited to one common service part and the tub is sound. Replace the dishwasher when you have chronic leaks, a damaged tub, or multiple major failures stacking up.

Our repair vs. replace checklist

• One symptom, one part (won’t drain, won’t start, no heat): repair is the best value.
• Leaks from the tub or severe corrosion: replace.
• Repeat breakdowns in different systems: replace.
• Repair cost rule: if the total repair approaches 50% of a comparable new dishwasher, replace.

Common CDT805P2N3S1 repairs that usually pay off

• Not draining: inspect the drain path; replace the dishwasher drain pump WD19X25461 if the pump is seized or noisy.
• Won’t latch or won’t start: check the strike and latch; replace the GE dishwasher door latch lock WD21X10490 if it won’t hold the door closed.
• Poor drying or no heat: heating circuit issues can involve the element heat WD05X35098.

Quick checks before buying parts

Disconnect power before any internal inspection.

• Confirm the door closes firmly and the latch engages.
• Make sure the water valve under the sink is fully on.
• Reset a tripped breaker; some installs use a wall switch for dishwasher power.
• If it won’t fill, check the flood float area for sticking (steps and safety notes are in the CDT805P2N3S1 owner's manual).

Cost and effort comparison

Situation	What it usually means	Best next step
Single clear failure	High chance of a straightforward fix	Diagnose, then replace the failed part
Multiple symptoms	Costs add up quickly	Price parts and labor; consider replacement
Tub leak or structural damage	Not a practical repair	Replace the dishwasher

Why it matters

A targeted repair keeps your existing cabinet fit and plumbing connections, and it restores cleaning and drying performance without the time and cost of a full replacement.
