SKS dishwashers
PowerSteam machines with a fully published code table.
SKS dishwashers - PowerSteam and QuadWash Pro machines through the new second generation - are the brand's most readable appliances: the official manual publishes the complete two-letter code table, from IE fills to AE leaks. The SignaLight even projects machine status as colored light.
A photo of the model label and the complete installation helps the team understand the configuration before the visit.

Start with the symptom
Common SKS 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.
Lighting
Red SignaLight
A code is showing in the edge display - photograph it; that is the diagnosis.
Symptom
Dishes wet
Steam-assisted drying needs a healthy heater (HE territory) and rinse aid.
Water
Standing water
OE's checklist - hose, air gap, disposer plug, filters.
Power
Won't power off
The AE leak lockout doing its documented job.
Surface
Film on glassware
Hard water versus settings - guidance before parts.
Door
FlushFit door rubbing
Gen-2 flush installs leave tight clearances - alignment is a real adjustment.
Series and model numbers
SKS dishwasher series we service
Two generations, one honest table - and status lights that tell you to look at the hidden edge display.

What to note
Published in full in the official manual.
Model label
Where to find your SKS model number
The label is on the side edge of the door or the underside of the control panel - visible with the door open, per LG's documented locations. Photograph the complete label — the full model and serial identify parts and production year better than the series name alone.
Indicators and alerts
SKS dishwasher alerts & indicators
For any message not shown, use the manual for the exact model rather than a generic list.
Message / alert
AE with the machine refusing to power off
What it means
Leak protection - the machine periodically pumps out and blocks shutdown until the leak is addressed. That behavior is documented, not haunted.
Safe check
Close the water supply, protect the floor, book with priority.
SKS diagnostics
SKS dishwasher error codes, decoded.
The complete table is verbatim from the official SKSDW2401S manual and matches the LG platform's documented meanings - a genuinely well-documented machine, and we use every letter of it.
Error code · IE
Not filling
What it commonly means
Water is not arriving - kinked or frozen supply, closed tap.
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 order; the valve replaced if it fails under test.
Error code · OE
Not draining
What it commonly means
Drain hose, air gap, disposer or filters - including the classic un-knocked disposer plug on new installs.
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 leg is cleared and tested; installation faults named as such.
Error code · bE
Excess foam
What it commonly means
Wrong detergent or an unlevel 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
Foam purge, detergent guidance and leveling.
Error code · AE
Leak detected
What it commonly means
The leak sensor found water - the machine self-drains and locks until fixed.
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
Source located, pan dried, full-cycle verification.
Error code · FE
Overfill
What it commonly means
More water than the cycle allows.
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
Inlet valve and level sensing diagnosis.
Error code · HE / tE
Heater / thermistor faults
What it commonly means
The heater circuit or water-temperature sensor failed.
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
Direct circuit testing - documented service codes.
Error code · LE / NE
Wash motor / Vario motor
What it commonly means
The circulation motor or the spray-diverting Vario motor reports failure.
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
Motor and diverter diagnosis per the table.
Not a fault · P1-P4, L0-L4, CL
Not faults
What it commonly means
Download-cycle slots, rinse-aid levels and Control Lock - status displays that get mistaken for errors.
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
Explained, not billed.
Any other code or behavior
Meanings vary by series and year
Why we do not guess
SKS 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
SKS dishwasher maintenance
Alpha Pro provides preventive and general maintenance for SKS 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

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
SKS dishwashers across San Diego
Alpha Pro serves SKS dishwashers in communities including La Jolla, Del Mar, Rancho Santa Fe, Carmel Valley, Poway, and the full San Diego County footprint below — ZIP by ZIP. Installation and room conditions vary from the coast to inland homes.
Coastal homes
Moisture, ventilation, and accessible surfaces
Recurring condensation, marine exposure, ventilation limits, and visible corrosion can be useful details during repair or maintenance.
Inland homes
Ambient heat and equipment environment
Share room conditions, recent heat events, ventilation restrictions, and when the symptom appears.
During maintenance, accessible metal surfaces can be inspected for corrosion, moisture exposure, or conditions that may warrant attention. Location alone does not establish the cause of a failure.
There is no honest universal age or price threshold. Start with the exact model and a diagnosis.

Helpful answers
SKS dishwasher service questions
Clear preparation makes a service request easier to evaluate.
Do you offer same-day SKS 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 SKS 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 AE mean on my SKS dishwasher?
Leak detected - the machine self-drains and refuses to power off until the leak is addressed. Close the supply and book; that lockout is documented protective behavior.
Why is my SignaLight red?
It projects machine status - red means a fault code is showing on the edge display. Photograph the code; it maps directly to the official table.
Is IE serious?
Usually not - it means water is not arriving: tap, hose or valve. It is the most commonly self-resolved code in the table.
Where is the model number?
On the door's side edge or under the control panel - door open.
Are P1-P4 on the display errors?
No - those are downloaded-cycle slots. L-numbers are rinse-aid level, CL is the control lock. Status, not faults.
