I smelled something burning, my husband checked the dishwasher and thinks the circuit board burned up. Can you offer any assistance in figuring out the exact problem and if it is worth fixing? We aren't quite ready to buy a new one, yet, but will in the future as this is an old machine.

Well, chances are it is the control board, but you will want to cut the power to the unit (at the breaker box if possible) and open the door panel by removing the screws on the edges. Make sure there isn't a crack that is allowing water to get on the board.
The control board can be a bit intimidating when you look at it, but replacement is quite easy. A search with the term "control board" and the model # (use the model number on the sticker inside the door of the dishwasher) as well as the brand, and you should find a number of places to get one.
Just remember to change the board with the power off, and move the plugs one at a time to the new board so that you don't get confused.

Had the same issue with a 903sa. Strong burning smell. Continued to run for a while then just died. Opened the control panel (4 screws holding the plastic part at the top of the door on - open the door to access).
Mains feed into the controller was totally fried. Case was all melted. Very nasty. There was nothing obvious on the Board other than a mains resistor that looked like it had been pretty hot at some stage. The three pin mains connector (at least I think it was 3 pins) was just a big, charred bit of goop.
This is an interesting problem and it requires some testing equipment to see what the problem is. You have to check the heating coil if it is a washer that heats the water. You also need to check the control board and some other things to see if you can locate the source of the burining smell. To perform these checks requite some test equipment like a meter.
Re: clean light blinks seven times on Kenmore Dishwasher model # 66516034401
After reading online and studying the parts diagram/list (included with
paperwork that came with washer) and troubleshooting guide/wiring
schematic (located under the bottom front kick panel) I determined it
could only be 5 things, all easy to look at and check when you pull out
the dishwasher (remove racks first and cut power via the circuit
They are heating element, wiring check for burn marks/melting), high
limit thermostat (mounted on bottom of tub against tub, detects if tub
overheats), thermistor (screw in mount near motor, detects process temp
inside dishwasher, and the control panel. Unfortunately, I started
buying and replacing the parts piecemeal (first high limit thermostat,
then thermistor, then heating element, even though it tested good).
Only then did I remove the panel (top 6 screws inside door, no need to
remove the whole door panel) and check the circuit board. After
separating the circuit board from its plastic case that covers the back
of the board, I saw that the back of the board was badly
burned/blackened about the size of a fifty cent piece around the heater
circuit relay (this was not visible from the front). Bingo. I should
have done a comprehensive check first and save $100 on parts that were
probably good. When ordering online, the circuit board part was
changed, perhaps to an improved part if the relay burning out is a
common problem. Good luck.
You should have it checked, but in most cases something has gotten onto the heater element and was burned. But DO NOT, just think this, check the element in the bottom,and look for a burn mark on it, if you do not see anything on it or a mark,then assume it is an electrical problem, pump motor, drain motor, and have it checked. Any questions please post back,everyone is happy to help.
Had the exact same problem (Control panel burning up, sparking, and smoking during wash cycle) last night with our Kenmore Elite DW model 665.16293400 purchased Nov. 2004. I have reported it to the CPSC and www.kitchenaidfire.com and will be contacting Sears first thing tomorrow. It is outrageous that this problem is apparently so widespread with nothing being done about it! I have no doubt my kitchen would have been in flames if I had not been sitting right here to shut off power to the D/W.
Ron, is this a dishwasher or clothes washer? If a dishwasher, check the wire nuts in the junction box. If there isn't a melted wire nut from a loose connection. Then you have to pull the outer door panel, then you can pull the control panel assy. This will require a t20 torx bit.
