LXiH

Overview

The Hobart LXiH is a front-opening commercial dishmachine equipped for freestanding or undercounter installation. It is a high-temperature sanitation model: a built-in booster heater raises incoming water from a minimum of 110°F to a minimum of 180°F for the final rinse. The LXiH is rated for up to 30 racks per hour and uses 0.74 gallons of water per rack.

The automatic cycle fills the wash tank, recirculates that wash water during the wash, drains off some wash water before the rinse, and uses the rinse cycle to refresh the wash water and tank heat. The cycle can be interrupted by opening the door and continues when the door is closed.

Key Features

Installation & Requirements

Electrical

The LXiH is listed with 120/208–240 V, 60 Hz, single-phase and 208–240 V, 60 Hz, single-phase electrical specifications. The sheet also lists non-standard three-phase and 50 Hz options in the specifications above. The electrical connection is through a 1 3/8-inch-diameter hole for 1-inch trade-size conduit, located 31 3/4 inches above the finished floor. The specified supply wiring is stranded copper rated for 90°C. Electrical and grounding connections must comply with applicable electrical codes.

Water and drain

The fill and rinse supply uses a 3/4-inch female garden-hose fitting on the supplied 6-foot hose. LXiH requires water at a minimum of 110°F. Required flowing water pressure is 20 ± 5 PSIG; if pressure above 25 PSIG is present, the sheet calls for a pressure-regulating valve in the water line. The drain connection is a 3/4-inch MPT fitting with a supplied 6-foot hose, and the pumped drain permits a maximum drain height of 38 inches. If the drain hose is looped above a sink, the loop must not exceed 38 inches above the finished floor.

The plumbing notes recommend water hardness of 4–6 grains for best results and state a minimum required water conductivity of 30 micro-mhos per centimetre. A water-hammer arrestor meeting ASSE-1010 or equivalent is specified for the common water supply line at the service connection. Plumbing connections must comply with applicable sanitary, safety and plumbing codes.

Location and surrounding surfaces

Moist air can escape from the door during operation. The specification sheet advises using moisture-resistant materials beside and above the machine; it identifies stainless steel or other moisture-resistant shields as suitable for adjacent surfaces. A vent hood is not recommended above the LXi undercounter dishwasher because it does not produce excessive vapours. The vertical machine dimensions measured from the floor may be increased by 1 inch.

Operation

The machine fills its wash tank for the initial cycle and recirculates the wash water during subsequent washing. Some wash water drains before the rinse. The rinse refreshes the wash water and tank heat, while the LXiH booster heater raises incoming water from at least 110°F to a minimum rinse temperature of 180°F for high-temperature sanitation. The automatic wash and rinse cycle is controlled by solid-state electronics.

Opening the door interrupts a cycle; closing the door allows it to continue. The controls display cycle and temperature information. Automatic fill and pumped drain are standard features. The LXiH is rated at 30 racks per hour, with a 2-minute cycle and water consumption of 0.74 gallons per rack. Actual dish and glass counts in the specification are averages per rack.

Cleaning & Maintenance

The supplied LXi specification material identifies a removable stainless steel scrap screen and a delime notification with cycle. It does not provide a deliming procedure, cleaning steps, or a maintenance schedule. Follow the machine’s applicable operating instructions for procedures; the source material here does not specify additional cleaning directions or service intervals.

Troubleshooting

A service-forum discussion about an LXiH reports a wash pump that would not run. The reply notes that the exact machine options depend on its ML number and recommends identifying what the machine displays or sounds like and what happens during startup before diagnosing the fault. The reply explains that, after filling, the pump should run briefly and the display temperature should flash while the machine heats before a wash can be started. If the pump does not make that brief post-fill run, a door-switch problem is suggested as a possibility—not a confirmed diagnosis. The forum also asks whether an error message appears. The provided material does not give a reset procedure or a complete troubleshooting chart.

Applications

The LXiH suits commercial dishwashing stations that need a front-opening machine for undercounter or freestanding placement. Its 17-inch door opening, rack range from 10 × 20 inches to 20 × 20 inches, and acceptance of 16 × 18-inch cafeteria trays support washing dishware, glassware, and cafeteria trays. Its high-temperature booster-heater sanitation method distinguishes it from the chemical-sanitizing LXiC model.
