Are there any known problems with the Sears dishwasher Model #665.17829001? Specifically, my dishwasher periodically will not allow me to Quick Rinse or to set the Air Dry option. I have tried depressing the Lock On button for several seconds (in case it was accidentally set), but this seems to have no effect.
Could not find info on you Model Number but here is a tech sheet for a 1782900. Hopefully it is close to yours.
You will notice that both Quick Rinse and Air Dry use contact P1-13.
This connect may be dirty or the ribbon cable track could be cracked.
Try the following
Unplug the unit
Open it up
Remove the ribbon cable from the keypad to the control board at the control board.
Clean the edge connector.
If it is the type where there is not a connector just the insulation is removed, it can be cleaned with a pencil eraser. Do not use an ink eraser as it is too abrasive.
Check the tracks in the ribbon cable for hairline cracks. A magnifying glass helps here.
Would not hurt to clean the connector on the board. Use electronics contact cleaner or isopropyl alcohol and a tooth brush. Be gentle and do not reconnect till all the solvent evaporates.
Reconnect everything and give it a try.
Great help. My wife ordered a new one - over $1600, to replace this one that is 7 years old. I disconnected the ribbons in the control panel and reconnected them and now it works. Maybe we can get another couple years out of this one. Thanks
