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.
