The Whirlpool GHW9100LQ is a first-generation Duet front-load washing machine manufactured by Whirlpool Corporation and sold in the early-to-mid 2000s. It represents the platform on which Whirlpool’s front-load washer expertise was established in the North American market, a machine that introduced millions of households to high-efficiency horizontal-axis washing. Despite its age, the GHW9100LQ remains in widespread service due to its robust mechanical construction and the continued availability of replacement parts. Understanding its complete technical specifications is the essential starting point for every repair, parts sourcing decision, and diagnostic procedure.
This reference document compiles every factory specification for the GHW9100LQ, organized by system category, with contextual explanation of what each specification means for performance, maintenance, and repair.
IDENTIFICATION AND MODEL INFORMATION
- Model number: GHW9100LQ
- Color/finish: White (Q suffix in model number denotes white finish; GHW9100LW denotes bisque/almond)
- Product line: Whirlpool Duet
- Machine type: Front-load, horizontal-axis washing machine
- Manufacture period: Approximately 2002–2007
- Country of manufacture: Germany (Whirlpool’s Schorndorf plant produced early Duet units)
- Service manual designation: W10006355
PHYSICAL DIMENSIONS AND WEIGHT
- Height: 38.75 inches (98.4 cm) without pedestal
- Width: 27 inches (68.6 cm)
- Depth (without door open): 30.5 inches (77.5 cm)
- Depth (with door fully open): approximately 52 inches (132 cm)
- Weight (shipping): approximately 220 lbs (100 kg)
- Weight (installed, without water): approximately 195 lbs (88.5 kg)
Installation clearance requirements:
- Minimum side clearance (each side): 1 inch (2.5 cm) for adequate ventilation
- Rear clearance: 2 inches (5 cm) minimum for hose and cord access
- Floor requirements: level, solid floor capable of supporting the unit under load; maximum unlevel tolerance 1 degree before suspension system efficiency is reduced
DRUM AND CAPACITY SPECIFICATIONS
- Inner drum volume: 3.8 cubic feet (IEC measurement) / approximately 3.0 cubic feet (DOE measurement)
- Drum material: Stainless steel perforated inner drum
- Drum opening diameter: approximately 15 inches (38 cm)
- Door opening angle: approximately 150 degrees
- Maximum load weight (dry): approximately 12–14 lbs (5.4–6.4 kg) for a typical mixed load
The GHW9100LQ’s 3.8 cubic foot IEC capacity was considered large for a residential front-loader at its time of introduction. The horizontal-axis drum rotation tumbles clothing through a small pool of water at the drum base rather than immersing it, which is the fundamental efficiency mechanism of front-load vs. top-load washing.
MOTOR AND DRIVE SYSTEM SPECIFICATIONS
- Motor type: AC induction motor
- Drive system: Belt drive (6-ribbed Poly-V drive belt connecting motor pulley to drum pulley)
- Motor control: Variable frequency drive via Motor Control Unit (MCU)
- Spin speed range: 47 RPM (tumble) to 1,000 RPM (maximum spin)
- Intermediate spin speeds: Multiple programmatic speeds through frequency control (300, 500, 700, 1000 RPM)
The belt-drive system is a critical component interaction: the motor does not drive the drum shaft directly but through a multi-groove drive belt. Belt wear, stretching, or breakage is a common failure mode that presents as a washer that tumbles but does not spin, or cannot achieve high spin speeds. The belt replacement procedure is covered in the companion guide Whirlpool Duet GHW9100LQ Drive Belt (6-Groove) Replacement Guide.
ELECTRICAL SPECIFICATIONS
- Supply voltage: 120V AC, 60 Hz
- Circuit requirement: Dedicated 20-amp circuit (15-amp minimum)
- Maximum power consumption: approximately 750W (during motor operation)
- Standby power draw: less than 5W
- Power cord length: 6 feet (1.83 m)
- Plug type: NEMA 5-15P (standard 3-prong, 120V)
The 120V specification is notable; the GHW9100LQ is a 120V-only machine, in contrast to some full-size European front-loaders that require 240V. This makes it directly compatible with standard North American household wiring without any electrical modifications.
WATER SYSTEM SPECIFICATIONS
- Hot water inlet connection: 3/4-inch garden hose thread
- Cold water inlet connection: 3/4-inch garden hose thread
- Water inlet pressure range: 20–100 PSI (operating range); 30–60 PSI optimal
- Water temperature range (hot supply): up to 130°F (54°C). The machine controls wash temperature through the inlet valve; supply temperature above 130°F may exceed internal thermostat range
- Water consumption per cycle: approximately 10–15 gallons (38–57 liters) depending on cycle and load, approximately 35–50% less than a comparable top-load machine of the same era
- Drain height requirement: standpipe or laundry tub minimum 39 inches (99 cm), maximum 96 inches (244 cm) from floor
