GE Dishwasher IH (1H) Code: Delay Start Is Set (How to Cancel It)

What the code means

GE Appliances' dishwasher fault-code list puts 'Number + H (Ex. 1H)' at the top and defines it as the dishwasher being in Delay Start mode. The first character is the number 1, not the letter I, which is why people search for 'IH'. GE's Delay Start article explains that on touch-control models each press of the Delay Start pad adds one hour of delay (1 to 14 hours depending on model), the display shows the hours as a number plus H, the control counts down by itself, and the programmed cycle starts when the countdown ends. Opening or unlatching the door does not cancel the delay. Newer GE models call the feature Delay Hours; most allow up to 8 hours and some up to 12. On mechanical-dial models there is no H display; you turn the dial to the 1 to 6 hour delay positions instead.

Likely causes

• Delay Start (or Delay Hours) was pressed once, setting a 1-hour delay, so the display reads 1H and the dishwasher waits before starting
• The Delay pad was pressed more than once, giving 2H, 3H or more, and the display counts down as the hours pass
• A delay was set by accident while choosing a cycle or wiping the control panel
• The door was opened and closed, which GE says does not cancel a delay, so the delay is still counting down

Safe DIY checks

1. Look closely at the display: if it reads 1H, 2H, 3H or similar, the dishwasher is simply waiting to start, not reporting an error.
2. To keep the delay, close and latch the door and leave it; the cycle starts on its own when the countdown reaches zero.
3. To cancel on models with a Delay Start pad, press the pad repeatedly until the hours indicator goes off.
4. On newer models with a Delay Hours pad there is no Off setting, so keep pressing and releasing Delay Hours until no number shows.
5. On most models you can also press and hold Start or Start/Reset for 3 seconds, which cancels the set cycle, including the delay.
6. Select your cycle and options again, press Start, and close and latch the door to run it right away.
7. On a dial-control model, turn the dial off the Delay Start hour positions to the cycle you want.
