CL44E

Overview

The Hobart CL44E is a high-temperature conveyor dishwasher for commercial dishwashing operations. It is rated to process up to 202 racks per hour, with a 23-gallon wash tank and a conveyor speed of 5.6 feet per minute. The supplied configuration is identified as CL44E-3Ph-208V. Confirm the desired travel direction and the available electrical service when specifying the machine for a dishroom.

The product information describes high-temperature water sanitizing and identifies Opti-RinSe™ as an integrated rinse feature. A rapid-return conveyor drive and insulated hinged double doors with interlock switches are also listed. The chamber opening is 19.5 inches high, a useful fit detail when planning the types of racks and wares to process.

Installation & Requirements

Confirm that the available electrical service matches the listed CL44E-3Ph-208V configuration: 208 volts, three phase, 55 amps and 15 kW. The product information identifies the dishwasher as hard wired. Have a qualified professional confirm the connection and site requirements for the specific machine before installation.

Allow for the listed machine dimensions of 44-3/4 inches wide and 68-1/2 inches high, as well as access needed for the hinged doors and the dishroom’s loading and unloading workflow. The supplied product information lists left-to-right conveyor travel; verify that this direction suits the layout. These details do not replace a review of the manufacturer’s installation documentation for the exact machine configuration.

Operation

The CL44E moves racks through the dishwasher on a conveyor, with a stated maximum rate of 202 racks per hour and a conveyor speed of 5.6 feet per minute. The machine’s product information identifies high-temperature water sanitizing and Opti-RinSe™. The 19.5-inch chamber opening is a key consideration when selecting racks and wares for the machine.

The CL-series manual says to begin preparation with the dishwasher clean and all parts in place. Where a scrapper is fitted, the manual describes installing the standpipe with strainer in the first tank where the rack enters, fitting the rear and side strainer pans, lowering the scrap basket, and installing the upper and lower wash arms with their sliders closed. For wash/rinse tanks, it describes fitting the appropriate standpipe or standpipes, strainer pan and scrap basket, then installing the upper and lower wash arms with sliders closed. These preparation details are conditional on the machine’s fitted tank and scrapper configuration.

Cleaning & Maintenance

The available manual excerpt does not specify a cleaning schedule or maintenance interval for this exact CL44E configuration. It does state that the dishwasher should be clean and all parts should be in place before preparation for operation. The manual also identifies removable components that must be correctly fitted for operation, including standpipes, strainer pans, scrap baskets and wash arms, depending on the fitted tank arrangement.

If dishes are not clean, the manual’s troubleshooting guidance points to checking for insufficient wash water, a drain obstruction or a worn or torn drain O-ring that allows wash water to drain. It also lists wash-arm sliders left open, obstructed wash-arm nozzles, a worn or torn manifold O-ring, and loss of water pressure caused by pump obstructions. For pump-intake inspection, the manual directs the operator to disconnect electrical power and follow lockout/tagout procedures, noting that multiple circuits may be present, then drain the tank or tanks and check the pump intake for obstructions.

Troubleshooting

The CL-series manual lists these possible causes when there is no machine operation: a blown fuse or tripped circuit breaker at the power supply; inspection doors 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. Its listed responses include pushing Start or inserting a rack after an auto-timer timeout, and pressing Wash on the HMI to resume from Energy Saver Mode. The manual also identifies a jammed conveyor as a possible cause; it does not provide an operator repair procedure for a jam in the excerpt supplied.

For a tank that will not fill, the manual’s error guidance says to check that the drain is closed, the incoming water supply is on and the fill hose is not kinked. It gives a water-pressure range of 20–65 psi for this troubleshooting check. For errors 020 and 023, the guidance is to retry filling after the listed checks; if the error persists, contact Hobart Service. Error 018 indicates a wash-tank water level above the upper limit; the guidance is to check the drain for obstructions and drain the machine, then contact Hobart Service if the problem persists or the machine cannot drain.

The manual also lists error 029 for a wash interrupted when a door is opened during operation, and errors 083 and 084 for final-rinse temperature too low. For error 083, it says to press Enter to clear the error and contact Hobart Service if it persists. For error 084, it says the wash cycle stops; pressing Enter clears the error and turns the machine off, and persistent issues should be referred to Hobart Service. Errors 085 and 086 identify wash-tank and booster over-temperature trips and direct the operator to contact service.

For errors 088 and 089, the manual describes a wash-tank or booster heater contactor that remains on despite a software command to turn off. Its instruction is to turn off the machine’s circuit breaker or breakers, not drain the machine, and contact Hobart Service. The supplied manual excerpt does not define Hobart error 31, so its meaning should be confirmed using documentation for the exact control and model or through Hobart Service.

Applications

The stated capacity makes the CL44E a candidate for commercial dishrooms that process a steady flow of racks, such as restaurant, hotel or institutional kitchens. Check rack volume, chamber-opening fit, conveyor direction and the listed electrical requirements against the intended dishroom workflow before selecting the machine.
