DH6000

Overview

The Champion DH6000 is a high-temperature, hood-type commercial dishwashing machine. Champion describes the DH6000 as a door machine; the installation manual identifies the machine as a hot-water sanitizing unit. The hood lifts to allow a rack to be loaded into the wash area. The manual says machines ship for straight-through operation and can be converted in the field for corner operation.

The machine has an advanced touchscreen display with condition alerts and multilingual, user-friendly cleaning information, according to Champion’s product information. The DH6000 is intended for commercial warewashing, where operators need a rack-style machine for dishes and other kitchenware. The available listing information identifies one peg rack and one flat rack as included with the DH6000.

Key Features

• High-temperature, hot-water sanitizing: The DH6000 is identified as a high-temperature machine and as a hot-water sanitizing machine in its manual.
• Hood-type rack loading: The hood-style format provides access to the wash area for loading and unloading racks.
• Touchscreen controls: Champion’s product information describes an advanced touchscreen with condition alerts and multilingual cleaning information.
• Flexible layout: The machine ships configured for straight-through operation and can be field-converted for corner operation.
• Commercial chemical connections: The manual describes detergent and rinse-aid signal connections for dispensing systems supplied by others, as well as optional Champion chemical dispensers.
• Vent-fan control signal: The standard DH6000 includes a fused signal connection for an external vent-fan contactor supplied by others. The signal is not a connection for powering a fan motor.

• Included racks: One peg rack and one flat rack, as stated in the DH6000 product listing.
• Electrical connection: The installation manual provides single- and three-phase connection procedures. The machine’s connection must follow its electrical data plate; the supplied sources do not establish one universal voltage or amperage for every DH6000.

Installation & Requirements

Installation must comply with local electrical, plumbing, health, and safety codes. Where local codes are absent, the manual specifies installation according to the applicable requirements in the National Electrical Code, NFPA 70; Canadian Electrical Code, Part 1, CSA C22.1; and NFPA 96 for ventilation control and fire protection of commercial cooking operations.

Placement and dish tables

Before installation, compare the site utility connections with the machine’s utility connections. The manual specifies providing 20 inches on the right, left, and front sides of the machine, and 27 inches above the finished floor. Four adjustable feet are provided for levelling; level the machine front-to-back and side-to-side. Do not attach dish tables until the dishwasher is in its permanent location. For table connections, the manual instructs installers to mark and drill 1/4-inch holes through the table flange and wash tank, apply sealant between the flange and tank, and secure the flange with stainless-steel 1/4-20 fasteners.

Water, drain, and electrical connections

Connect the cold-water supply and drain in accordance with the manual and applicable local codes. The manual identifies a minimum 3/4-inch NPT cold-water supply and a 1-inch NPT electric drain valve connection. It also cautions that damage caused by improper drain installation is not covered by the limited warranty. For electrical work, use the connection data plate attached near the terminal blocks and follow the applicable single- or three-phase connection instructions. The manual calls for copper supply conductors rated for a minimum of 90°C and requires compliance with local electrical code.

Ventilation and chemical equipment

The standard DH6000 has a fused 120 VAC signal for an external vent-fan contactor supplied by others. The signal is limited to a maximum load of 1.0 amp; the manual explicitly warns not to connect a vent-fan motor to the signal terminals. Detergent and rinse-aid dispensing systems are also supplied by others unless optional Champion dispensers are fitted. The manual describes signal connections for these systems and specifies that the detergent signal is enabled during the wash cycle and the rinse-aid signal during the rinse cycle.

The optional electric drain water-tempering equipment has separate water requirements in the manual: a dedicated minimum 1/2-inch NPT cold-water supply, incoming water temperature of 55–75°F (13–24°C), flowing pressure of 46–50 PSI, and water hardness of 3 grains per US gallon or less. These requirements apply to that optional equipment, not as a replacement for the DH6000’s main cold-water supply specification.

Operation

For startup, the manual instructs the operator to check that chemical containers are full and pickup tubes are installed, turn on the water supply, energize the machine, and press the green start button. The operation screen then appears. The touchscreen displays operating information and condition alerts; when a fault occurs, the display presents a fault message or icon with instructions for the operator.

Use only non-chlorinated commercial dishwashing chemicals in the machine. Warewashing chemicals are supplied by others, and the manual directs users to follow the chemical supplier’s instructions for proper handling and use. Optional detergent and rinse-aid dispensing equipment should be set up according to the applicable chemical and dispenser instructions.

The manual also describes a delime operation. During the procedure, the machine fills, prompts the operator to add deliming chemical, and asks for the doors to be closed to start. The pump circulates the deliming solution for the preset period; the machine then drains it, fills with fresh water, and runs the delime rinse. The manual cautions that the operator cannot exit the operation after chemical is added and that only an authorized service agent can stop the delime operation once it is underway. If equipped, the machine may lock the door until the operation is finished.

Cleaning & Maintenance

Champion provides a DH6000 Series operation and cleaning guide, and the manual includes deliming instructions. For deliming, follow the chemical supplier’s instructions, wear protective clothing and eye protection when handling chemicals, and observe the machine’s touchscreen prompts. The manual warns that deliming chemicals cannot be cancelled from the operator interface after they have been added.

The installation and operation material supplied for this listing does not give a routine cleaning schedule or a complete daily cleaning sequence. It does state that regular maintenance and cleaning are the operator’s responsibility, and that damage associated with failure to follow maintenance and operating procedures is not covered by the manual’s warranty terms. For routine cleaning steps, use the Champion DH6000 Series cleaning guide rather than assuming a schedule or procedure not stated here.

Troubleshooting

The touchscreen reports machine conditions through fault messages and icons. The manual describes these examples:

• Drain time exceeded: This message appears if the machine does not drain completely within the allotted time. The operator can acknowledge the on-screen instructions. If the fault is not corrected, the machine may resume normal operation with a blinking icon indicating that it is still running in a drain-fault condition and needs repair. Contact a service agent.
• Float fault: The internal floats control filling and heating. The manual instructs the operator to select the fault icon, follow the on-screen instructions, and press Reset. If the fault returns, contact a service agent.
• Temperature sensor fault: The manual includes this as a displayed fault. Follow the instructions shown on the machine’s fault screen; the supplied excerpt does not provide further repair steps.

The manual cautions that electrical service work requires power to be turned off at the dishwasher and the main circuit breaker disconnected. It also notes that more than one power source may be connected to the machine. Use a qualified service agent for repairs that require access to electrical components or for unresolved machine faults.

Applications

The DH6000 is suited to commercial dishrooms in restaurants, hotels, institutional kitchens, and other food-service operations that handle racks of dishes and kitchenware. Its hood-type loading arrangement supports a dish-table workflow, with straight-through or field-converted corner placement to suit the room layout. Confirm the site’s utilities, space, and applicable local requirements against the machine’s installation manual before purchase and installation.
