The control continuously monitors system parameters for control and oven failures and reports a fault code when a system problem is detected. The control utilizes the ovens blue “on light” and oven “heating light” to report a detected fault code. The control will continue to flash the lights in the appropriate sequence as long as the fault exists.

HOW TO INTERPRET CODES
When a fault occurs, the control will flash the blue oven “on light” and the Blue “heating light” sequentially to indicate the fault. The fault codes have two numbers, these numbers are interpreted by the number of times the lights flash. The oven “on light” will flash indicating the first number, and the “heating light” will flash indicating the second number.
EXAMPLE:
Error E9 is…. No Cooling Fans. The code is 43. The oven “on light” will flash four times, then the “heating light” will flash three times, then pause. The sequence will then repeat as long as the fault is present.

ERROR CODES FOR OVENS WITH DREEFS CONTROL
The following chart shows the error codes that can be displayed in the Oven/Selector window during specific oven malfunctions. Some of the error messages can be cleared by performing the following steps:
1. Turn the selector knob to OFF
2. “Tweak” the oven by turning the selector knob slightly to the left (counterclockwise). This may stop the flashing message/beeping and
3. For errors E1, E9, E11, E12 and E13, the power supply going to the even must be turned off momentarily, and back on again
4. If an error remains displayed when the selector switch is OFF, and after attempting to clear the display, as shown in steps 2 and 3, turn off the power going to the oven, and refer to the chart below to help you find the problem.

ERROR CODE NOTES
DESCRIPTION OF PROBLEM
Control board problem.
Cook or Clean mode runaway (temp >635 °F). Clean mode runaway (clean temp +32 °F). Open oven temperature sensor (>5000 Ω).
Shorted oven temperature sensor (<5000 Ω). Control board too cold, too hot, or defective. Control board problem. Illegal temperature display. Turn off oven and try again. Control board problem. Latch switch problem. Control board problem. CT oven – latch switch problem CT ovens – latch switch problem CT ovens – latch frozen or no power to latch motor.
CMT ovens – control board not converted (refer to page 3-7 for conversion data). Latch switch problem.
Control board problem.
ERROR CODE NOTES:
A Turns heat off on the failed oven only; microwave not affected. B Turns all heat off; microwave not affected. C Disables the CLEAN mode in both ovens; allows COOK and microwave. D Error will remain in the display until oven is repaired and powered back up. No error tones. E Turning the oven off stops the error and flashing display. Can tweak away the error code. Error is
redisplayed only if the selector is turned to CLEAN. F Tweaking clears to “---“ for retry. G Clears when the oven temperature is less then the runaway temperature with the selector switch off. H Can be cancelled by tweaking if a good sensor is detected. I Cleared with a mode change. J Can be tweaked away for immediate retry. User must unlatch and delete the “---“ to try to relatch the
door. K Turns heat and microwave off. L If two switches show a locked door, then E13 and LOCK are permanent in the display (in all modes).
If the two switches show an open door, tweak away the E13 error message.

The control continuously monitors system parameters for control and oven failures and reports a fault code when a system problem is detected. The control utilizes the ovens blue “on light” and oven “heating light” to report a detected fault code. The control will continue to flash the lights in the appropriate sequence as long as the fault exists.
Detection of a fault does not hinder the ability of the control to continue to function if the fault is not critical for the intended operation. For example: If the range door latch is inoperative, the range will continue to cook since the fault would only prevent the range from self-cleaning.

Note 2 Oven sensor should measure 1050
ohms at 75 degrees F. If the sensor measures correctly (within 10%) check each leg of the sensor to ground and to each phase of the electrical supply. If all checks OK, check the contacts inside the molex plug. If the spring contacts are bent or crushed, the sensor will create intermittent errors.
Note 3 The touch panel assembly uses
electronic keys and a microprocessor to signal functions. The program is set to scan the electronic touch pads constantly, and if this process is interrupted the microprocessor will turn all of the keys on electronically. If these errors are noted, please turn off the power to the oven, check all of the harnesses on the touch panel and reset the power. This will usually clear the errors.

Note 4 The touch panel is an
electronic switching device so it does not have actual keys that stick. The control head was designed for use with either membrane switches or electronic inputs.
Our touch panel constantly polls or checks the touch pads for inputs. If the cable has a poor connection or intermittent connection, the microprocessor will electronically switch all of the keys on, this will produce an F7 error which the control head indicates as stuck key.

HBL/HBN 7 FAULT CODE DEFINITIONS
AND BASIC TROUBLESHOOTING
HINT: After a latch fault, due to any hardware problem, the control can disable one cavity and prevent the opposite one to work in self-clean. First remove the fault cause, then after a latch auto­test at power-up, if either cavities or clean mode are still inhibited, press and hold the [Start] key for one minute until F121 is displayed, then press [Cancel].
Generally, to cancel a persistent fault, press and hold the [Start] key for one minute until F121 is displayed, then press [Cancel].
HINT: Sometimes at power-up, the F155 fault code is displayed. Press [Cancel] key to reset the alarm. If F155 is displayed again when starting a cooking mode, it means that parameters are corrupted in the Display Board and the EEPROM needs to be re-programmed. Otherwise, the oven will work correctly.

Dishwasher Error codes
Error codes that the consumer will see on models with numeric display:
F Indicates a water level or filing error. Underfill, overfill or water in the base. See note 1 2H Indicates that the last wash cycle took over 99 minutes to complete. Usually indicates inlet water too cold, or heating fault in the dishwasher. See note 1 & 2
Error codes only displayed in diagnostic program: See note 3
Models with numeric display:
0 No faults 1 Aqua Sensor “Sensotronic” fault 2 Heating fault 4 Filling fault 8 NTC (temperature sensor) fault
Models without numeric display:
LED’s on the buttons will be lit to indicate faults. Please refer to B/S/H Dishwasher Troubleshooting Tips or Major Appliances Technical Manual for specific model / code information.

Dishwasher Error Codes…continued
NOTE 1 Once cause of this fault has been corrected, the code will reset itself 15 minutes after
The dishwasher has been turned on, or by running the dishwasher through the diagnostic program. See B/S/H Dishwasher Troubleshooting Tips, or Major Appliances Technical Manual for instruction by model number.
Note 2 Heating faults must be tested in the diagnostic mode. The diagnostic program will begin with running the
drain motor for 30 seconds, then it will check the aqua sensor (if equipped) for 65 seconds, filling until water level switch is closed, and then the circulation pump and heater will be activated. To test heater circuit, put amprobe around the red wire from control board to the base. It would read approximately 10 amps if all is working properly. If no amperage is indicated , test for voltage (120VAC) at the red wire. If voltage is present, but no amperage, the heater assembly is at fault. If no voltage is present, the relay contact on the control board is most likely the cause. Resolder the connection as per instructions in
B/S/H service bulletin.
Note 3 Each model dishwasher has a diagnostic program which allows the technician to quickly diagnose
specific faults without having to wait for a regular wash cycle to reach the proper time for specific events to occur. Each program will begin by running the drain motor for 30 seconds, calibrating the aqua sensor for 65 seconds (if model is equipped with aqua sensor), filing until water level switch (f1) is closed, the cir culation motor begins to run, the soap dispenser actuates, and the heater will be activated to heat the water to 150 degrees, and the unit will drain. The instruction for entering the diagnostic programs and specific fault code indication are listed in the B/S/H Dishwasher Troubleshooting Tips manual or the
Major Appliance Technical Manual.
Note 4 If multiple faults occur, the numeric codes will be added and displayed as a total, for example, if the unit
had both a heating and an aqua sensor fault, the numeric indication would be 5, 1 for aqua sensor fault plus 4 for the heating fault.
