1. Check P2 connector on the Display Board and the wires.
2. Check the connection terminals on the socket mounted on the cavity
left sidewall. They may be shorted or have a loose contact (for
example, through the aluminum foil around the insulating material).
Lock symbol is always displayed.
1. Check the latch and door switches and their connections.
2. Check if any shorts on P4 (for upper or single oven) or P24 (for lower
oven) connector pins.
3. If everything is OK, try to replace the Power Board.
Some of the keys are not working.
No beeps when touched and
expected action not executed.

Check P10 connector on the Display Board and the wires. (Check also
P19 terminal for single oven only).
2. For double oven only, check P2 connector on the Auxiliary Relay
Board and the relay outputs.
3. If relay outputs don’t work, check also the two low voltage cables
between Power and Auxiliary Board.
4. Check R2 (39 ohms) resistor in series with the fan coil.
1. Check P10 connector and P19 terminal on the single oven Power
Board or P11 connector on the double oven Power Board and their
connections. If Power Board output is not activated, replace the board.
2. Check R1 (78 ohms) resistor in series with the fan coil.
3. Check the circuit (latch switch) to by-pass the resistor for high speed
in self-clean.

elements.
2. Check the relay outputs on the Power Board.
All the elements are not energized. 1. Check the common L1 red wire on the Power Board relays.
2. Check the safety thermostat connection in series with black L2 wire.
3. Check, if present, the DLB relay connections on the Auxiliary Relay
Board.
4. Check, if present, the DLB relay outputs. If they are not OK, replace
the Auxiliary Relay Board.
Display never turns on
1. Check Power supply connection on the Power Board (P18 for double
oven, P5 for single oven).
2. Check the P1A cable between Power and Display Board.
3. Disconnected the P1A cable and measure by a meter the voltages on
the P1A connector on the Power Board.
a. If they meet the values indicated in the electric schematics then
replace the Display Board.
b. If they don’t meet, replace the Power Board.

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.
