CL64-BAS

Overview

The Hobart CL64-BAS is a high-temperature rack conveyor dishwasher with electric tank heat. It is part of Hobart’s CL Series and is specified for commercial dishwashing. The manufacturer lists a capacity of up to 342 racks per hour and a pumped final rinse rate of 114 gallons per hour. The standard chamber opening is 19.5 inches high and can accommodate up to six standard sheet pans at a time when they are carried on an open-end sheet pan rack.

The CL64-BAS uses a wash-tank pressure sensor rather than conventional mechanical floats. Its touchscreen controls provide diagnostics and troubleshooting information, while WiFi connectivity works with the SmartConnect app and cloud for machine status, temperature logs, error-code reporting, and cost, consumption, and usage analysis.

Installation & Requirements

Installation and utility connections must follow the CL-Series manual and applicable local codes. The details below are those stated for CL-BAS models or for the CL64-BAS configuration; the manual’s gas-heat instructions do not apply to this electric tank-heat model.

Water supply

Drain connection

Electrical and accessories

The spec sheet identifies an internal 24 kW booster heater and a standard single-point electrical connection. It also states that the dish machine is not provided with internal GFCI protection. Optional accessories listed for the CL64-BAS include standard, short, and extended stainless steel vent hoods; a direct-drive unloader; side loaders; an electric or steam blower-dryer; a drain water tempering kit; flanged feet; a higher-than-standard chamber; a table limit switch; a correctional package; a water hammer arrester; and factory-mounted circuit breakers. These are options, not standard features.

Operation

Before operation, the manual directs the operator to make sure the dishwasher is clean and all parts are in place. Install the standpipe or standpipes in the tank or tanks, then install the strainer pan and scrap basket. Install the upper and lower wash arms with their sliders in the closed position, pushing each arm onto its connector pipe and seating the opposite end in its guide. The manual gives separate directions for the scrapper when the machine is equipped with one: place the standpipe with strainer in the first tank where the rack enters, fit the rear and side strainer pans, lower the scrap basket, and install the scrapper wash arms.

The machine’s touchscreen provides diagnostics and troubleshooting information. WiFi connectivity and SmartConnect provide access to machine status, temperature logs, error-code reporting, and analysis of cost, consumption, and usage. The energy-saver mode can be programmed for automatic shut-down.

Cleaning & Maintenance

The manual excerpt specifies that the large double-door opening is provided for ease of cleaning. Before operating, confirm the machine is clean and its parts are in place, including the standpipe or standpipes, strainer pan, scrap basket, and wash arms. For a dishes-not-clean condition, the manual identifies checking for drain obstruction, wash-arm slider position, wash-arm nozzle obstruction, manifold O-ring wear or damage, and pump obstruction as troubleshooting checks. It directs operators to disconnect electrical power and follow lockout/tagout procedures before checking the pump intake; it warns that there may be multiple circuits. Drain the tank or tanks before checking for an obstruction at the pump intake. No routine cleaning interval is stated in the provided material.

Troubleshooting

Machine does not operate

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

Dishes are not clean

Listed possible causes include insufficient wash water; a drain obstruction causing an open-drain condition; a worn or torn drain O-ring allowing wash water to drain; open wash-arm sliders; a blocked wash-arm nozzle; a worn or torn manifold O-ring allowing wash water to drain; loss of water pressure due to pump obstruction; and incorrect water temperature. For an obstruction at the pump intake, the manual requires disconnecting electrical power, following lockout/tagout procedures, and draining the tank or tanks before inspection. For incorrect water temperature, it directs the operator to check the circuit breaker to the electric heat supply.

Error messages

• 016 or 017: Wash-tank pressure-sensor failure. The manual describes a short circuit or a level above the maximum for 016, and an open circuit or failure to reach the minimum level 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 or 023: Tank-fill time exceeded. Confirm the drain is closed, the incoming water supply is on, and the fill hose is not kinked; verify water pressure is 20–65 PSI. For 020, the manual also says to drain the machine and try filling again. Contact Hobart Service if the error persists.
• 029: Wash interrupted because a door was opened during operation. Close the door or doors.
• 083 or 084: Final-rinse temperature did not reach the minimum within the set time. Press Enter to clear the error; for 084, the wash cycle is stopped and the machine turns off after clearing. Contact Hobart Service if the error persists.
• 085 or 086: Wash-tank or booster over-temperature trip. Contact Hobart Service.
• 088 or 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 or 095: Power-rinse tank pressure-sensor failure. Contact Hobart Service.
• 100 or 101: Power-rinse temperature-sensor failure. Contact Hobart Service.
• 102 or 103: Drain water tempering temperature-sensor failure. If the drain water tempering 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 listed capacity of up to 342 racks per hour suits commercial dishrooms handling a high volume of rack-based warewashing. The 19.5-inch chamber opening and stated capacity for up to six standard sheet pans on an open-end sheet pan rack also support kitchens that need to wash sheet pans alongside their regular dishware. The configurable pot-and-pan cycle provides a specified cycle option for pots and pans.
