Dacor dishwashers
WaterWall hydraulics, four honest letters on the display.
Dacor's current dishwashers - the Contemporary DDW24M with its WaterWall spray bar and the Transitional DDW24T - report a compact, officially documented code set: LC, 3C, 4C and 5C. The legacy Epicure-era machines speak a different F-code dialect. The model plate decides which conversation the visit has.
A photo of the model label and the complete installation helps the team understand the configuration before the visit.

Model label
Where to find your Dacor model number
The model and serial plate is on the side edge of the door, visible when the door is open. Photograph it before booking - the suffix letters matter for parts. Photograph the complete label — the full model and serial identify parts and production year better than the series name alone.
Indicators and alerts
Dacor dishwasher alerts & indicators
For any message not shown, use the manual for the exact model rather than a generic list.
Message / alert
LC on the display
What it means
The leak sensor has detected moisture in the base - the machine is protecting your floor.
Safe check
Close the water supply, protect the floor and book with priority; LC will not clear until the source is found.
Dacor diagnostics
Dacor dishwasher error codes, decoded.
LC, 3C, 4C and 5C come from the official DDW24M99-series user manual; F:10/F:11 from the official DDW24S service manual. Codes circulating online beyond these are excluded.
Error code · LC
Leak sensor detection
What it commonly means
Official Dacor code: moisture reached the base-pan sensor - a real leak somewhere in the machine.
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, the pan dried and a full cycle verified before the code is cleared.
Error code · 4C
Water supply check
What it commonly means
Officially: valve closed, supply suspended, or the inlet valve or line clogged or frozen.
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 supply path is tested in the official order - most 4C calls end at the valve or its screen.
Error code · 5C
Drain check
What it commonly means
Officially: drain hose clogged or folded, or the drain hole inside the pump clogged.
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 drain path is cleared end to end and the pump tested under load.
Error code · 3C
Pump operation check
What it commonly means
The official manual says: turn off and restart; if it continues, service.
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 circulation pump and its control are tested directly - the honest step after the restart.
Legacy dialect · F:10 / F:11 (legacy DDW24S)
Drain timeouts
What it commonly means
Official service-manual codes on the legacy platform: water not emptied within 60 or 120 seconds.
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 pump, hose routing and check valve serviced per the legacy manual.
Any other code or behavior
Meanings vary by series and year
Why we do not guess
Dacor 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.

Dacor Dishwasher Repair Across San Diego County
Dacor started in 1965 in Southern California, and its dishwashers now fall into two families. Legacy units from the Distinctive, Renaissance and Heritage era report faults with F-codes and beep patterns. Newer 24-inch panel-ready and stainless models arrived after Samsung Electronics America agreed to acquire Dacor in August 2016. We service both across the county. This page covers the code list for older models, how county water varies by district, what Dacor's warranty covers, and how to weigh a repair on each generation.
From 9 to 16 Grains: County Water and Your Dishwasher
The San Diego County Water Authority wholesales water to 22 retail agencies, and almost every one of them delivers hard or very hard water. The latest figures range widely. In 2025 reports, the City of San Diego ran 237 to 243 mg/L depending on the treatment plant. Helix measured 206 mg/L, Sweetwater 193 mg/L and the Otay system 9.4 grains per gallon. In 2024, Poway averaged 236 mg/L and Santa Fe Irrigation District about 275 mg/L. The practical range at the tap is roughly 9 to 16 grains per gallon. For a Dacor dishwasher, harder water means faster scale on the flow-through heater, inlet screen and spray arms, and a shorter descaling interval. Climate splits the county too. Coastal homes live with damp, salty marine air that corrodes exposed door hardware, and many sit empty part of the year, which dries seals. Inland and South Bay homes in Poway and Chula Vista run larger households, around three people each, so cycle counts and pump wear rise. September heat waves strain the grid, and power sags during outages can upset electronic controls. Our city pages go deeper on each area.
Legacy Dacor Codes and Beep Patterns Explained
F2 and F3: water supply codes
Symptom: F2 means the inlet valve will not shut and the tub keeps filling. F3 means low inlet pressure and a long fill. Cause: A worn or scaled inlet valve, a control fault, a clogged inlet screen or a partly closed supply valve. Fix: We test the valve and control output, clean the screen and replace the valve or board as needed.
F4 and F5: sensing and control codes
Symptom: F4 flags the pressure switch and F5 flags the control board. The cycle may stall or never advance. Cause: A failed pressure switch or a blocked sensing hose, or a board fault. Fix: We clear the hose, test the switch and diagnose the board before ordering parts.
F9: heater failure
Symptom: Cold washes and wet dishes at the end of the cycle. Cause: The inline flow-through heater has failed, often after years of hard-water scale. Fix: We confirm the failure with a meter, replace the heater and check the harness and connector for heat damage before the next cycle.
Beep patterns: drain and base-pan leak
Symptom: Three long beeps with a flashing red light means failed to drain. Three beeps with the drain pump running means water in the base pan. Cause: A clogged filter, pump or house drain, or an internal leak from a seal, hose or oversudsing. Fix: We clear the drain path or find and repair the leak, then dry the base.
Setting Maintenance to Your Water District
Look up your provider's latest water quality report and use its hardness figure to set your routine. Filter cleaning every few months is standard, monthly with heavy use. Rinse aid is essential everywhere in the county. These code references come from repair guides that do not name model years and most likely describe legacy units. Samsung-era Dacor dishwashers may show different codes, so always check the manual for your model.
Very hard water (above 230 mg/L): descale every six to eight weeks
Hard water (9 to 12 gpg): descale every two to three months
Clean the filter monthly in households of three or more
Second homes: run a short cycle weekly
Keep rinse aid filled year-round
How a Countywide Dacor Service Call Works
We cover the county from coastal condos to inland family homes. Access differs by area: high-rise buildings need elevator reservations and sometimes insurance certificates, gated communities need codes, and rural lots need clear directions. Panel-ready Dacor dishwashers take extra time because the cabinet front must come off. When you book, tell us the model and serial number from the tub edge, the code or beep pattern, your water district and the purchase date. That lets us bring the likely parts on the first trip.
Economics of Repair on Legacy and Samsung-Era Units
Dacor lists a two-year full warranty on units bought on or after November 1, 2020, so newer machines should go through Dacor first. Out of warranty, valves, switches, heaters and pumps are usually worth repairing. Legacy units with a discontinued board are the main case for replacement. Our $99 diagnostic is credited to the repair.
Helpful answers
Dacor dishwasher service questions
Clear preparation makes a service request easier to evaluate.
Do you offer same-day Dacor 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 Dacor 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 LC mean on my Dacor dishwasher?
The leak sensor found moisture in the base pan. Close the water supply and book promptly - the code stays until the actual leak is located and repaired.
What is the 4C code?
A water-supply fault, officially: closed valve, suspended supply or a clogged inlet path. The supply side is tested in order before any part is named.
My dishwasher shows 3C - what should I do?
The official first step is a restart. If 3C returns, the circulation pump and its control need direct testing - that is the visit.
Where is the model number?
On the side edge of the door, visible when the door is open.
Do you service the older Epicure-era Dacor dishwashers?
Yes - the legacy platform has its own F-code dialect and service manual, and parts are ordered by the full model from the plate.
Who makes Dacor dishwashers now?
Dacor was founded in 1965 and designed and built its products in Southern California. Samsung Electronics America agreed to acquire it in August 2016, and it now operates as a Samsung subsidiary. Current Dacor dishwashers are 24-inch panel-ready and stainless models from the Samsung era.
Do the F-codes on this page apply to my new Dacor?
Probably not. The published code list does not specify model years and most likely covers legacy Dacor dishwashers. Samsung-era models may use a different code set. Check the manual for your model number, or tell us the display reading and model when you book.
How hard is the water where I live in San Diego County?
It depends on your retail water agency. Recent reports run from about 9.4 grains per gallon in the Otay system to around 275 mg/L in Santa Fe Irrigation District, with most city systems near 14 grains. Your agency's annual water quality report lists the figure.
Is it worth repairing a Dacor dishwasher that is more than ten years old?
Often, if the tub is sound and the failed part is a pump, valve, switch or heater. General guidance puts dishwasher lifespan around 10 to 13 years, so a tub or discontinued board failure past that point is a reasonable time to replace instead.
