My dishwasher only runs for two minutes and shuts off, no matter what cycle it is set for. The control board was replaced and it still does the same thing. I was told that there is a series of codes that can be used to reset the board. Is this true and what would they be? Is this even the problem?

Batty, you can put the dishwasher in a automatic test mode or manual test mode. For automatic press the heavy wash key 5 times followed by the start key. 88 should show in the display if you have the digital display. It's going to check the wash motor, fill valve, drain motor, soap dispenser, vent and heater automatically. If any of these systems fail, you will get a code. The test will finish by itself. You can get the information to test the touch panel by getting the tech sheet from behind the bottom toe panel. Catriver..post back.

It sounds like you have a faulty electronic control board. This board starts & stops the washing, draining & drying cycles. The board cost about $96.00.
To replace the control board:
1.) You will receive the new control board in a silver anti-static bag. It is critical to ground your self by touching metal objects. Static electricity will knock out a board.
2.) Turn off the circuit breaker to the dishwasher.
3.) Remove the control panel cover. There are 2 screws on each side in the back of the cover. Remove the cover.
4.) Disconnect the electrical connector on the board. Remove the board from its housing. Install the new board and plug in the electrical connector.
5.) Remount the control panel cover.
6.) Turn on the power breaker.
There is a slight possibility the problem could be the detergent dispenser. This is an electrical component with a solenoid valve.
The electrical control board send a signal to the dispenser to activate. Lack of dispenser cycling may stop the unit.
Lets check it out: (Power Breaker is Turned Off)
1.) Remove the dishwasher front cover. There is a series of screws on the inside door holding the front cover. You may have a electrical power strip to disconnect.
2.) With the front cover removed, you will see two wires attached to metal contacts. Disconnect the wire leads.
3.) With a multi-meter, set to the lowest Ohm reading, touch the 2 meter leads together. You should get a reading of 1.0 Ohms.
4.) Touch one lead on each of the metal connectors on the dispenser. If good you should get a reading of '0', showing the dispenser is good. If the meter needle does not move or reads other than '0', the dispenser needs to be replaced.
Remember this is a long shot.
If your Dishwasher is stuck in a cycle check the following
The float switch may be hung up and this can cause the dishwasher to be stuck in a cycle.
Timer / Control
If your dishwasher gets stuck in a cycle first try shutting off the breaker for at least 5 minutes if this does not correct the problem you will need to replace timer/electronic control board God bless you use the VOM..
How long does it stay in the wash cycle? Indefinitely? Does the display continuously show "WASH"?. If it stays in the wash cycle indefinitely (i.e. continuously shows "WASH" for significantly beyond approx. 3 minutes), it's probably a control board malfunction. If it continues to wash after the "WASH" indicator goes out, it could be a shorted wash motor relay on the relay board or a fauly control board.
If the internal rinse water booster heater doesn't reach it's programmed setpoint temperature in time, the dishwasher will run an extended wash cycle to give the booster heater more time to finish heating the rinse water. If this is what's happening, the wash cycle would last approximately 3 minutes, then it would rinse regardless of whether the booster heater has finished heating or not.
The booster temperature thermistor may be bad, giving a false booster temperature reading, causing an extended wash cycle as described above. The booster heater elements or contactor may be bad, preventing the booster heater from heating and reaching proper temperature, also causing the same extended wash cycle to give the booster more time to heat.
HI, this is a control fault. the logic chips are malfunctioning. these chips are responsible for initiating the proper washing cycle sequences. you will need to replace this damaged control board asap.
Ok, this is a control fault that may be corrected by shutting the power off for 5 minutes. this will reset the chip set on the control board. plug the unit back into the socket after the 5 minute ait and check to see if the element is still on. If so, replace the control board.
When the water stops too soon, it could be the "over flow" is stuck in the downward position, therefore the dishwasher thinks it's going to over flow. Check that out. Otherwise I'm afraid this sounds like the circuit board is shot.
Hey Jim, if your model starts with 665 there was a service flash on this unit concerning your problem. SF-22-715. Dishwasher stops in mid cycle. The control board was redesigned to eliminate this problem. The service flash states that if only one indicator light is blinking it's usually a stuck or shorted keypad. I would check with Sears and see if you are covered under this service flash. Catriver...post back.
