CL54-ADV

Overview

The Hobart CL54-ADV is a conveyor dishwasher in the CL-Series. Its installation and operation manual covers the CL54-ADV alongside other CL-Series models and provides specific incoming-water requirements for CL-ADV machines in the CL54 size group. The manual identifies a 24 kW built-in booster for the CL54, CL64, CL76 and CL86 models; the CL54-ADV therefore uses the 24 kW entry in the CL-ADV water-temperature table.

The manual also states that a drain water tempering kit is factory installed on all CL-ADV models. The instructions include water and drain connections, preparation before operation, and troubleshooting guidance for alarms and operating symptoms. Where the manual gives instructions for optional or conditional configurations, they are identified as such below rather than treated as standard equipment on this unit.

Installation & Requirements

Water supply

The manual calls for both hot and cold incoming water connections on CL-DWR and CL-ADV models. Use an incoming-water line with a minimum inside diameter of 1/2 inch. For the CL-ADV with the 24 kW built-in booster, the manual lists cold water at 55°F to 80°F and hot water at a minimum of 110°F. The hot-water entry has no maximum temperature listed in that table. The manual also states that a required water pressure regulator must have a relief bypass; it warns that using the wrong regulator type may damage the unit.

Drain

The common drain for the tank or tanks needs one connection to the floor drain and can be connected at either end of the drain body; a pipe plug is provided for the other end. The manual notes that factory drain plumbing on CL-DWR and CL-ADV models may need to be relocated to the opposite side of the drain body. Connect the drain through a trap to the sewer with 2-inch NPT pipe. If a grease trap is required by local code, the manual specifies a minimum flow capacity of 38 gallons per minute.

The drain water tempering kit is factory installed on CL-ADV models. The manual directs installers to the kit’s separate installation instructions for proper installation. It also states that the drain water tempering kit is available as an accessory for CL-BAS and CL-VL models; those models are not the subject of this page.

Electrical and other connections

The supplied manual material identifies a 24 kW built-in booster for the CL54 size group but does not provide the CL54-ADV’s electrical voltage, phase, amperage, wire size or connection details. Confirm the unit’s nameplate and applicable Hobart installation documentation for those ratings before making electrical connections. The manual excerpt also describes connections for optional external equipment, but does not establish that such equipment is included with this dishwasher.

Operation

Preparation

Before operation, the manual instructs the operator to make sure the dishwasher is clean and all parts are in place. Install the appropriate standpipe or standpipes in the tank or tanks. The manual specifies that a standpipe with a strainer belongs in the first tank where a rack enters the machine; a standpipe without a strainer belongs in a second or third tank where applicable.

Install the strainer pan and scrap basket as applicable. The manual gives additional preparation steps for machines equipped with a scrapper: install the standpipe in the scrapper tank, place the standpipe with strainer in the first tank, fit the rear and side strainer pans, and lower the scrap basket. Install upper and lower wash arms with their sliders closed. Push each arm onto its connector pipe so the opposite end is held by the guide, then lift or lower it into position. These scrapper-specific steps apply only if the machine is equipped with a scrapper.

Starting and resuming operation

The manual’s no-operation troubleshooting guidance says to check that inspection doors are closed and that the conveyor is not jammed. If the auto-timer has timed out, push START or insert a rack. If a table limit switch is used, it may have tripped. When the machine is in Energy Saver Mode, press WASH on the HMI to resume. The manual also lists a blown fuse or tripped circuit breaker at the power supply as a possible cause of no operation.

Cleaning & Maintenance

The provided manual instructions specifically say to begin preparation with a clean machine and all parts in place. They identify the standpipes, strainer pans, scrap basket and wash arms as components to fit before operation. The troubleshooting section also directs operators investigating poor cleaning to check for wash-arm slider positions and nozzle obstructions, and to check the pump intake for obstructions if water pressure has been lost.

For an inspection of the pump intake, the manual requires disconnecting electrical power and following lockout/tagout procedures. It warns that there may be multiple circuits and says to ensure all circuits are disconnected. Drain the tank or tanks before checking the pump intake. The supplied manual text does not state a routine cleaning schedule or maintenance interval, so none is specified here.

Troubleshooting

No machine operation

The manual lists these possible causes: a blown fuse or tripped supply circuit breaker; an open inspection door; a jammed conveyor; an auto-timer timeout; a tripped table limit switch, if one is used; or Energy Saver Mode. Its corresponding checks include closing the inspection doors, clearing a conveyor jam, pushing START or inserting a rack after an auto-timer timeout, and pressing WASH to resume from Energy Saver Mode.

Dishes not clean

Possible causes listed in the manual include insufficient wash water, 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, loss of water pressure due to pump obstructions, or incorrect water temperature. The manual also says to check the electrical supply breaker, main steam valve or gas supply valve as applicable to the machine’s heat configuration. For a pump-intake obstruction check, follow the power-disconnection and lockout/tagout instructions in the Cleaning & Maintenance section.

Displayed errors

• Error 018 — Wash tank water level is too high: The manual says the level is above the upper limit. Check the drain for obstructions and drain the machine. Contact Hobart Service if the error persists or the machine cannot be drained.
• Errors 020 and 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 error 020, the manual says to drain the machine and try filling again; for error 023, retry after checking the supply. Contact Hobart Service if the error persists.
• Error 029 — Wash interrupted: The message indicates that a door was opened during operation. Close the door or doors as indicated by the display.
• Errors 083 and 084 — Final rinse temperature too low: The final rinse did not reach the minimum temperature within the set time. For error 083, press ENTER to clear the error; if it persists, contact Hobart Service. For error 084, press ENTER to clear it; the machine will turn off. Contact Hobart Service if the issue persists.
• Error 234 — External conveyor not ready: The manual associates this message with an external conveyor that is off, has an error or is not connected. Confirm that the external conveyor has power and no errors; contact Hobart Service if the message persists.

The manual directs operators to contact Hobart Service for the listed sensor failures, heater over-temperature trips and other errors marked for service. Follow the instruction displayed for the specific error rather than attempting a repair outside the manual’s troubleshooting steps.

Applications

The CL54-ADV’s conveyor format is suited to commercial foodservice warewashing workflows where racks move through the dishwasher. Example settings include restaurant kitchens, institutional foodservice and other commercial kitchens handling repeated rack loads. The manual does not provide a rack-per-hour figure in the supplied material, so throughput is not stated here.
