CL66-BAS

Overview

The Hobart CL66-BAS is a commercial conveyor dishwasher in the CL-Series. A product listing for the CL66-BAS+BUILDUP identifies it as a 44-inch, single-tank conveyor dishwasher with a power scrapper. The listing notes that the BUILDUP model includes the base dishwasher unit only; optional accessories and attachments may be sold separately unless stated otherwise. Confirm the supplied configuration when reviewing a quote.

The CL-Series manual lists BAS models alongside DWR and ADV versions, as well as other CL sizes. Those are related models, not alternate names for the CL66-BAS. A retailer identifies the CLPS66EN-BAS+BUILDUP as a new equivalent model; confirm current model availability and configuration before choosing a replacement.

These are gas-heat figures, not electrical ratings.

Installation & Requirements

Water supply

The manual specifies a single hot-water supply for CL-BAS models. The required incoming temperature depends on the sanitizing method and whether a built-in booster is fitted; use the applicable values in the specifications above. If a drain water tempering kit is installed on a BAS model, an additional cold-water supply is required. The manual says the kit is available as an accessory for CL-BAS.

Use an incoming water line with a minimum 1/2-inch internal diameter. For the fill-related troubleshooting procedure, the manual gives a water pressure range of 20–65 psi. Hobart suggests a water softener when water hardness is 3 grains or more.

Drain

The common drain for the tank or tanks needs one connection to the floor drain and can be connected at either end; a pipe plug is provided for the other end. Connect the drain through a trap to the sewer using 2-inch NPT pipe. Where a grease trap is required by code, the manual specifies a minimum flow capacity of 38 gallons per minute.

Gas heat, when fitted

The manual’s gas instructions apply only when the dishwasher is equipped with gas tank heat. Check the machine’s gas data plate for the required gas type. Machines are shipped configured for natural gas; if conversion to propane is needed, the manual says a conversion kit and instructions are supplied and must be installed before operation. The CL44/CL66 gas table gives the connection, BTU/hr and pressure information listed above. The manual also requires a shut-off valve and says the appliance and gas connections must be leak-tested with soapy water, not an open flame. Gas installations in Canada must comply with CAN/CSA B149.1 and CSA C22.1, as stated in the manual.

The available sources do not provide a CL66-BAS electrical rating or a complete model-specific clearance schedule. Confirm the exact machine configuration and its applicable installation documentation rather than assuming electrical or clearance requirements.

Operation

Before operating

The CL-Series manual instructs operators to make sure the dishwasher is clean and all parts are in place. Where a scrapper is fitted, install the standpipe with strainer in the first tank where the rack enters the machine. Install the rear and side strainer pans and lower the scrap basket. Fit the upper and lower wash arms with their sliders closed: push each arm onto its connector pipe, position the opposite end in the guide, then lift or lower the arm into place.

Install the standpipe or standpipes in the wash and rinse tanks. The manual distinguishes the standpipe with strainer used in the first scrapper tank from the standpipe without a strainer used in the second or third tank. Install the tank strainer pan and scrap basket, then position the wash arms as described in the manual.

During operation

The troubleshooting section identifies several operating conditions that can stop the machine: an open inspection door, a conveyor jam, an expired auto-timer, a tripped table limit switch when one is used, or 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 HMI to resume from Energy Saver Mode.

Cleaning & Maintenance

The manual’s preparation instructions make cleanliness and correctly installed parts a prerequisite to operation. It identifies the standpipes, strainer pans, scrap basket and wash arms as components to place correctly before running the dishwasher. For a dishes-not-clean condition involving a suspected pump obstruction, the manual directs operators to disconnect electrical power, follow lockout/tagout procedures, drain the tank or tanks and check for obstruction at the pump intake. It warns that there may be multiple electrical circuits and that all circuits must be disconnected.

The available manual excerpts do not specify a cleaning schedule or a maintenance interval. Follow the complete CL-Series manual for the procedures applicable to the installed machine.

Troubleshooting

Machine does not operate

The manual lists these possible causes: 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 fitted; or Energy Saver Mode. Check the listed condition: close inspection doors, clear a conveyor jam, push START or insert a rack after an auto-timer timeout, check the table limit switch if used, or press WASH on the HMI to resume from Energy Saver Mode. For a blown fuse or tripped breaker, the source identifies the cause but does not provide a repair procedure in the excerpt.

Dishes are not clean

The listed possible causes are insufficient wash water; a drain obstruction causing an open-drain condition; a worn or torn drain O-ring; wash-arm sliders left open; obstructed wash-arm nozzles; a worn or torn manifold O-ring; loss of water pressure due to pump obstruction; or incorrect water temperature. The manual says to check the electrical heat circuit breaker, main steam valve or gas supply valve as applicable when checking water temperature. For a suspected pump obstruction, disconnect all electrical circuits and follow lockout/tagout procedures before draining the tank or tanks and checking the pump intake.

Fill and water-level messages

For error 018, the manual says the wash-tank water level is above its upper limit. Check the drain for obstruction and drain the machine; contact Hobart Service if the error continues or the machine cannot drain. For errors 020 and 023, the tank did not fill, or its water level did not rise, within the anticipated time. Confirm the drain is closed, the water supply is on and the fill hose is not kinked; verify water pressure is 20–65 psi, then drain the machine and try filling again. Contact Hobart Service if the error persists.

Temperature, sensor and conveyor messages

The manual identifies errors 016 and 017 as wash-tank pressure sensor failures, and errors 094 and 095 as power-rinse tank pressure sensor failures; it directs operators to contact Hobart Service. Errors 083 and 084 indicate that final-rinse temperature did not reach the minimum within the set time. The manual says to press ENTER to clear the message; for error 084 the wash cycle stops and the machine turns off when the error is cleared. Contact Hobart Service if the problem persists.

Errors 085 and 086 indicate a wash-tank or booster over-temperature trip and call for service. For errors 088 and 089, the manual says the heater remains on while ignoring the software command to turn off: switch off the machine circuit breaker or breakers, do not drain the machine, and contact service. Error 234 indicates that an external conveyor is off, has an error or is not connected; confirm it has power and no errors, then contact service if the message remains. For service-directed messages, follow the manual rather than attempting an undocumented repair.

Applications

The conveyor format and power-scrapper listing make this model relevant to commercial dishrooms that process ware in racks and use a scrapping stage before washing. Confirm that the rack workflow, water supply, drain arrangement and chosen BAS configuration suit the intended operation before selecting the unit.
