5-2 5.2 Troubleshooting Guides COOKPOT DID NOT FILL WHEN UNIT WAS TURNED ON. WATER SUPPLY TO UNIT VERIFIED TO BE ON. Did anything appear in controller display when unit was turned on? Open control panel by removing screws in each upper corner. Is WATER LED on interface board illuminated? Probable causes are a failed water solenoid or a failed inter[...]

5-3 WATER DID NOT SHUT OFF WHEN COOKPOT WAS FULL. Use bottlebrush to clean water level sensors. Did water stop? Problem resolved. Add 1/8 cup of salt to water in cookpot and stir. Did water stop? Mineral content of water is insufficient for water sensor to detect it. Whenever cookpot is refilled, add 1/8 cup of salt. Open control panel by removing [...]

5-4 WATER NOT HEATING. AUTOFILL (IF INSTALLED) WORKED PROPERLY. Press the Temperature Check button twice to display setpoint. Has the correct setpoint been programmed? Did burners light? Did water reach setpoint temperature? Problem resolved. Insert a good grade thermometer into cookpot with tip near temperature probe and wait two minutes. Press th[...]

5-5 BURNERS DO NOT LIGHT. Verify that correct setpoint has been programmed, that main gas supply valve is open, and that equipment gas valve is set to ON. Press ON/OFF button. Did burners light?

6-10 tion failure situation may be encountered in which all com ponents appear to be serviceable and the microamp reading is within specification, but the unit nevertheless goes into ignition failure during operation. The probable cause in this case is an inte rmittent failure of an i gnition module. When the unit is opened up for troubleshooting, [...]

6-11 If popping is consistent during all hours of operation, the most likely cause is an insufficient air sup- ply. Check for “negative pressure” conditions in the kitchen area. If air is flowing into the kitchen area, this indicates that more air is being exhaus ted than is being replenished, and the burners may be starved for air. If the reth[...]

6-12 6.7.3 Improper Temperature Control Temperature control is a function of several inte rrelated com ponents, each of which must operate correctly. The principle component is the temper ature probe. Other components include the inter- face board, the water level sensors (on FBRA18 units ), the controller, and the ignition module. Whatever the cau[...]
