Safety Precautions

Before servicing, disconnect electrical power and water supply.

Electrical Safety: Always unplug unit or disconnect circuit breaker before accessing internal components.
Water Safety: Shut off water supply and relieve pressure before disconnecting lines.
Personal Safety: Wear safety glasses and gloves when handling sharp edges or hot components.
Component Handling: Allow heating element to cool completely before touching.

WARNING! Failure to follow safety procedures may result in electric shock, injury, or damage to the appliance.

Installation Instructions

Proper installation ensures optimal performance and safety.

Prepare opening: Ensure cabinet opening meets specified dimensions with level floor.
Connect water supply: Use 3/8" compression fitting on hot water line (120°F max).
Connect drain hose: Install high loop or air gap per local codes.
Level dishwasher: Adjust leveling legs for proper door alignment.
Secure to cabinet: Attach mounting brackets to adjacent cabinetry.
Electrical connection: Connect to dedicated 15-amp circuit with proper grounding.

CAUTION! Do not kink water supply or drain lines. Ensure all connections are tight and leak-free.

Electrical & Plumbing Connections

Electrical Requirements: 120V, 60Hz, 15A dedicated circuit with ground.
Water Supply: 3/8" OD copper tubing or braided stainless supply line.
Water Pressure: 20-120 psi static pressure.
Drain Requirements: 1/2" minimum ID drain line with air gap or high loop.
Maximum Inlet Water Temperature: 120°F (49°C).

Control Panel & Operation

Electronic touch controls with LED indicators and cycle progress display.

Control Buttons: POWER, CYCLE SELECT (Normal, Heavy, Light, Rinse Only, Sanitize), OPTIONS (Heated Dry, Delay Start, Sani Rinse), START/RESUME, LOCK.

Display Indicators: Cycle status, time remaining, error codes, lock icon, sanitized indicator.

Operation: Press POWER, select cycle, adjust options as needed, press START. Door locks automatically during operation.

Cycle Descriptions

Six wash cycles with customizable options.

Normal Wash: For everyday loads with medium soil. Default temperature 120°F.
Heavy Wash: For pots, pans, and heavily soiled items. Higher temperature and extended wash time.
Light Wash: For lightly soiled loads or quick wash. Reduced water and energy use.
Rinse Only: Rinses dishes without detergent to prevent drying of food particles.
Sanitize: Uses high-temperature final rinse (155°F) to reduce bacteria.
China/Crystal: Gentle wash for delicate items with lower water pressure.

Options: Heated Dry (on/off), Delay Start (1-24 hours), Sani Rinse (boosts final rinse temperature).

Diagnostic Mode & Error Codes

Enter diagnostic mode by pressing HEATED DRY + SANI RISE + START simultaneously for 3 seconds.

Error Code	Description	Possible Cause
E1	Water Fill Error	Water inlet valve, float switch, pressure switch
E2	Drain Error	Drain pump, drain hose obstruction
E3	Heating Error	Heating element, temperature sensor
E4	Door Lock Error	Door latch mechanism, lock switch
E5	Motor Error	Wash pump, motor control board
E6	Communication Error	Control board, wiring harness

Clear error codes by resetting power. If persistent, perform component testing.

Troubleshooting Guide

Symptom	Possible Cause	Corrective Action
Dishwasher won't start	Power, door latch, control lock	Check power supply, ensure door closed properly, disable control lock.
Poor cleaning results	Spray arms, filter, water temperature	Clean spray arms and filter, check inlet water temperature ≥120°F.
Water not draining	Drain pump, hose obstruction	Check drain pump operation, clear hose obstructions.
Leaking water	Door seal, hose connections, tub	Inspect door gasket, tighten connections, check tub for cracks.
Unusual noises	Spray arm obstruction, pump, mounting	Remove debris from spray arms, check pump, ensure unit is level.
Display shows error code	Component failure	Refer to Error Code section for diagnostics.
