Installation & Requirements

The manual’s CL-BAS water-temperature table also gives requirements for configurations without a built-in booster: for hot-water sanitizing, it lists hot water at a minimum of 180°F and a maximum of 194°F; for chemical sanitizing, it lists hot water at a minimum of 120°F. These conditions are for the no-booster configurations and should not be confused with the CL54-BAS specification’s built-in 24 kW booster.

The common tank drain requires one connection to the floor drain and may connect at either end of the drain body; the opposite end is plugged. The manual specifies a 2-inch NPT drain connection through a trap to the sewer. Where code requires a grease trap, the manual specifies a minimum flow capacity of 38 gallons per minute. A drain water tempering kit is available as an accessory for CL-BAS models; if installed on a BAS model, the manual notes that an additional cold-water supply is needed.

The spec sheet lists standard single-point electrical connection but the provided CL54-BAS electric spec-sheet text does not give voltage or amperage values. Confirm electrical requirements against the complete model-specific electrical documentation before planning the connection. The spec sheet lists standard, short and extended stainless steel vent hoods as optional accessories; it does not give airflow figures in the provided CL54-BAS electric information.

Operation

Before operation, the manual directs the operator to make sure the dishwasher is clean and all parts are in place. For a machine equipped with a scrapper, install the standpipe with strainer in the first tank where racks enter. Install the rear and side strainer pans, lower the scrap basket, and fit the upper and lower wash arms with their sliders closed. Push each arm onto its connector pipe so the opposite end is held by its guide, then lift or lower it into position.

For the wash and rinse tanks, install the standpipe or standpipes in the appropriate tank or tanks. The manual identifies the standpipe without a strainer for a second or third tank. Install the strainer pan and scrap basket, then fit the upper and lower wash arms with their sliders closed, ensuring each arm sits on its connector pipe and in its guide. The touchscreen provides machine diagnostics and troubleshooting; SmartConnect can report machine status, temperatures, error codes, and usage information.

Cleaning & Maintenance

The supplied manual excerpt directs operators to begin with a clean machine and confirm that its components are installed before use. Its preparation instructions identify the standpipes, strainer pans, scrap baskets and wash arms as parts to place in the tanks. The wash arms should be installed with sliders in the closed position and seated on their connector pipes and guides.

For a dishes-not-clean issue, the manual points operators to possible wash-water loss or restriction causes, including a drain obstruction that leaves the drain open, a worn or torn drain O-ring, open wash-arm sliders, obstructed wash-arm nozzles, a worn or torn manifold O-ring, and pump obstructions that reduce water pressure. Before checking a pump intake, the manual requires disconnecting electrical power and following lockout/tagout procedures; it cautions that there may be multiple circuits. Drain the tank or tanks and check for an obstruction at the pump intake. The provided excerpt does not specify a routine maintenance interval.

Troubleshooting

No machine operation

The manual lists these possible causes: a blown fuse or tripped circuit breaker at the power supply; an inspection door that is not closed; a jammed conveyor; an Auto-Timer that has timed out; a tripped table limit switch, if one is used; or the machine being in Energy Saver Mode. It says to push START or insert a rack if the Auto-Timer has timed out, and to press WASH on the HMI to resume from Energy Saver Mode.

Dishes not clean

In addition to the drain, O-ring, wash-arm and pump issues noted above, the manual lists incorrect water temperature as a possible cause. It directs the operator to check the electric-heat circuit breaker, main steam valve or gas supply valve, as applicable to the machine’s heat configuration.

Selected error messages in the manual

• 016 and 017: Wash-tank pressure sensor failure. The manual describes a sensor short circuit or maximum booster water level exceeded for 016, and an open circuit or minimum booster water level not reached for 017; it directs the operator to contact Hobart Service.
• 018: Wash-tank water level too high. Check the drain for obstructions and drain the machine; contact Hobart Service if the error persists or the machine cannot drain.
• 020 and 023: Tank-fill time exceeded. Confirm the drain is closed, check that the incoming water is on and the fill hose is not kinked, and verify water pressure is 20 to 65 psi. The manual also directs draining and refilling for error 020; contact Hobart Service if the issue persists.
• 029: Wash interrupted because a door was opened during operation; the on-screen instruction is to close the doors.
• 083 and 084: Final-rinse temperature too low. Press ENTER to clear the error; for 084, the wash cycle stops and the machine turns off. Contact Hobart Service if the error persists.
• 085 and 086: Wash-tank or booster overtemperature trip; contact Hobart Service.
• 088 and 089: Wash-tank or booster contactor error. The manual says to turn off the machine circuit breaker or breakers, not to drain the machine, and to contact Hobart Service.
• 094 and 095: Power-rinse tank pressure sensor failure; contact Hobart Service.
• 100 and 101: Power-rinse temperature sensor failure; contact Hobart Service.
• 102 and 103: Drain Water Tempering temperature sensor failure. If the DWT assembly is not installed, the manual says to disable DWT in the manager menu; otherwise contact service.
• 234: External conveyor not ready. Ensure the external conveyor has power and no errors; contact Hobart Service if the error persists.

Applications

The CL54-BAS is suited to commercial dishrooms that process racks of dishes and need a conveyor workflow. Its stated rack capacity supports high-volume warewashing, while the 19.5-inch chamber opening also accommodates standard sheet pans on an open-end sheet pan rack. The NSF-rated configurable pot and pan cycle provides a stated cycle option for pot-and-pan loads.
