GE Profile Dishwasher Shows Code 1h Will Not Start?

What does 1h mean on a GE dishwasher? 1h shows up and the dishwasher will not start up. Is this an error code? The “Ih” is really a “1h”. This means that you have a one hour delay start set on your GE dishwasher. You can start your GE dishwasher, wait 1 hour, and it will start the cycle after 1 hour. To cancel it out, press the START button until it cancels out the DELAY START. You can then use the dishwasher normally.

The code on the GE Dishwasher may look like a 1H, ih, IH, 1h, or an error code. However this is actually the number “1” with an “H” next to it. This code is officially 1h. 1h means a delayed start of the wash cycle for 1 hour.

In detail, this means that your dishwasher is programmed to delay the start function for 1 hour. To clear this and reset the control board, press the START button and clear the delay start program. If pressing the start button does not work, just wait 1 hour to see if it starts and resets the delay start function. Your dishwasher may be stuck on delay. If so, troubleshoot the control board for faults.

If the GE Dishwasher will not start or does not reset, you may have a faulty dishwasher control board. The control board is in the dishwasher door. If you find it to be faulty, here is a link to find a new control board for GE dishwasher.

We own a GE CDT725 dishwasher. It will not start. All of the lights on the control panel are lit, it is not locked, the rinse agent is full the door is closed, the water temperature is good. We have cycled the power on and off. It is on 0 delay. What else could be going on?
I called the 1-800 number and waited 30 minutes and gave up.
