Installation Guidelines

Step-by-step instructions for proper installation to ensure correct operation and avoid service calls.

Location: Install on level, solid floor near water supply, drain, and power outlet.
Water Connection: Connect to cold water line using new inlet hose. Check for leaks.
Drain Connection: Connect drain hose to standpipe (min. height 20") or sink connection with air gap.
Electrical Connection: Plug into dedicated, grounded 120V outlet. Do not use an extension cord.
Leveling: Adjust front feet to ensure unit is perfectly level. Check with spirit level.
Final Check: Run a short test cycle (e.g., Rinse) to verify no leaks and proper filling/draining.

WARNING! Incorrect installation can cause leaks, poor performance, and void warranty.

Control Panel & Functions

Overview of control panel buttons, indicators, and their corresponding functions for diagnostics.

Typical Controls: POWER ON/OFF, PROGRAM SELECTOR (Auto, Heavy, Normal, Eco, Quick, Rinse), OPTIONS (Half Load, Delay Start, Extra Dry), START/PAUSE.

Indicator Lights: Salt Indicator, Rinse Aid Indicator, Program Progress Lights, Error Code Display (if equipped).

Service Mode Access: Specific button combinations (e.g., holding two buttons for 3-5 seconds) to enter diagnostic mode for testing components and viewing error history.

Operational Cycles & Programs

Detailed breakdown of each wash program's sequence, timing, temperature, and water usage.

Auto Wash: Sensors determine soil level; adjusts time, temperature, and water accordingly.
Heavy Cycle: High-temperature wash (up to 155°F/68°C) for heavily soiled pots/pans.
Normal Cycle: Standard daily cycle for normally soiled dishes.
Eco Cycle: Energy-efficient cycle using less water and lower temperature over a longer period.
Quick Wash: Short cycle (approx. 30 mins) for lightly soiled loads.
Rinse Only: Uses cold water to rinse dishes without detergent.

Cycle Sequence: Pre-wash (if selected), Main Wash, Rinse(s), Final Rinse with Heated Dry.

Error Codes & Diagnostics

List of common error codes displayed or indicated by flashing lights, with diagnostic procedures.

Error Code	Description	Probable Cause
E1 / F1	Water Inlet Fault	Water supply off, clogged inlet filter, faulty inlet valve, pressure switch issue.
E2 / F2	Drainage Fault	Drain hose kinked/clogged, drain pump blocked/faulty, filter blocked.
E3 / F3	Heating Fault	Heating element failure, NTC temperature sensor fault, wiring issue.
E4 / F4	Water Leak Detected	Leakage sensor triggered. Check hoses, pump seals, tub for leaks.
E5 / F5	Motor/Pump Fault	Circulation pump jammed or motor failure.
E9 / Door	Door Lock Fault	Door not latching, faulty door lock mechanism or switch.

Disassembly & Component Access

Step-by-step guide to safely access major components for inspection and replacement.

Door Panel: Remove inner door liner screws to access detergent dispenser and door lock.
Control Panel: Remove top panel or trim to access electronic control board and wiring.
Lower Spray Arm & Filter Assembly: Twist and lift to remove for cleaning or pump access.
Pump Assembly: After removing filter, disconnect drain hose and unbolt pump housing.
Heating Element: Remove lower access panel (if external) or internal mounting screws.
Inlet Valve: Located at rear; disconnect water hose and wiring harness.

Tip: Take photos during disassembly and organize screws for reassembly.

Maintenance & Cleaning Procedures

Routine maintenance tasks to prevent common issues and ensure efficient operation.

Filter Cleaning: Remove coarse and fine filters weekly. Rinse under running water.
Spray Arm Cleaning: Monthly, check holes for debris. Remove and rinse arms.
Door Seal Wipe: Wipe clean with damp cloth to remove food residue and prevent mold.
Descaling: Run an empty cycle with dishwasher descaler every 2-3 months in hard water areas.
Rinse Aid & Salt Refill: Check and refill as indicated by panel lights.
Detergent Dispenser: Clean compartments to prevent clogging.

CAUTION! Use only cleaners recommended for dishwashers. Do not use abrasive pads.

Troubleshooting Flowcharts

Logical step-by-step guides for diagnosing symptoms without specific error codes.

Symptom	First Checks	Next Steps
Dishwasher won't start	Power at outlet? Door closed/latched? Water supply on? Start button pressed?	Check door switch, control board fuse, main power relay.
Not filling with water	Water tap on? Inlet hose kinked? Filter blocked?	Test inlet valve for 120V AC. Check pressure switch/flow meter.
Not draining	Drain hose kinked/blocked? Filter blocked?	Check drain pump for obstruction. Listen for pump motor hum. Test pump resistance.
Poor cleaning results	Spray arms blocked? Correct detergent used? Loaded properly?	Check water temperature (should be hot at inlet). Test heating element. Verify detergent dispenser opens.
Leaking water	Source of leak? (Door, pump, hose connections, tub)	Inspect door seal for damage. Tighten hose clamps. Check pump seal and tub for cracks.
Unusual noise	Grinding, humming, or rattling?	Check for foreign object in pump or spray arm bearings. Inspect wash motor mountings.
