GE dishwasher code 1H: what it means and how to clear it
You may see 1H on the display and read it as IH because the GE display uses a narrow number 1. This page explains what it means, how to clear it, and when a stuck delay setting points to a control problem.

GE dishwasher code 1H means the dishwasher is set for a 1 hour Delay Start, so it is waiting before it begins the wash cycle. The most common cause is someone bumping the Delay Hours button or selecting delay by mistake.
Check these first
Safe to do yourself. Unplug the appliance before you start.
- Read it as 1H, not IH
On many GE displays, the number 1 looks like a capital I. If the display changes to 2H, 3H, or more when you press Delay Hours, you're in the delay start timer.
- Press Delay Hours until it clears
Press Delay Hours repeatedly until the hour display is gone or returns to no delay. Some models scroll through several delay choices before they clear, so don't stop at 2H or 4H.
- Hold Start or Reset
Press and hold Start, Start/Reset, or Cancel for about 3 to 5 seconds. This often clears a stored delay setting on GE panels, then you can pick the cycle again.
- Close the door firmly after pressing Start
Select the cycle, press Start once, then close the door. If the door is left open too long or doesn't latch, some GE dishwashers will just sit with lights on.
- Cut power for 5 minutes
If the buttons respond but 1H keeps coming back, turn the dishwasher breaker off for 5 minutes, then turn it back on. This is a safe reset for the control, as long as you don't remove panels or touch wiring.
- Wait out the timer once
If you don't need the dishwasher right away, leave it alone for 1 hour. A real 1H delay should count down, then start the selected cycle.
Conditions that make this more likely
Boards fail earlier in hot rooms
Electronics are rated for room temperature. In a garage or an unconditioned laundry room in summer, a control board can sit well above that for hours a day. Before replacing a board, a good technician confirms the parts it controls test good, since a shorted pump or valve can take out a new board too.
What a technician tests
Most likely part first. These are for a technician with a meter and the tech sheet, not a weekend project.

Describe it on the phone. The company on the other end works on these every day and will know what to ask.

Is GE dishwasher code 1H an error code?
Usually, no. It is a Delay Start display for 1 hour, which is why the dishwasher may seem dead until the timer runs out.
Why does it look like IH instead of 1H?
The display uses a narrow number 1, so it can look like the letter I. If pressing Delay Hours changes it to 2H or 3H, that confirms it's a delay timer.
How do I reset a GE dishwasher with 1H showing?
Press Delay Hours until no delay is shown, then hold Start or Start/Reset for about 3 to 5 seconds. If it still stays on 1H, turn the breaker off for 5 minutes and try again.
Will the dishwasher run if I just wait?
Yes, if it is only set for 1H delay, it should start after 1 hour. If it never starts, clear the delay and check that the door is fully latched.
Should I call a repair company for 1H?
Try the delay and reset steps first. If 1H keeps returning or the control panel will not respond normally, a repair company can test the console and control boards.
