On this make a code belongs to the appliance rather than to a product line. These are the other conditions this machine can display, and the models that can show this one — a display often has more than one thing to say, and the model number decides what any of it costs to put right.

About GE dishwasher error code nH
What nH means, in the maker's own words
Not an error. GE describes a number followed by H — 1H, 2H and so on — as the delay start counting down: the machine is waiting the number of hours shown before it begins.
Where this code actually appears
On the control panel, and usually with a sound. GE describes their refrigerator codes as flashing green on the display and typically accompanied by a beeping, and the range, microwave and dishwasher tables all describe codes you can read from the front of the appliance. That is the opposite of some makes, where the number is written into a hidden log and never shown — here, if something is wrong, the appliance generally tells you. Photograph what it says before cutting the power, because a reset erases it and the code is most of the diagnosis.
Which machines this one applies to
Displayed as a number followed by H, e.g. 1H. GE says plainly on their own range and oven table that they cannot list every code for every model past and present, so a code missing from their table is not proof that your appliance cannot raise it — and a code in it is not proof that yours can. The model number settles it.
What to do about it
- Nothing needs fixing. The number is the hours remaining.
- To cancel it, press CANCEL and start the cycle you actually want.
- It is worth knowing because a dishwasher that 'will not start' is on delay start more often than anybody admits.
Where this goes next
The job this usually becomes is diagnostic visit, and every one of those pages carries a starting figure and the reasons that move it. If it turns out to be nothing — and on this make a real share of these are modes rather than problems — the visit ends there and you pay the diagnostic and nothing else, or call (305) 306-2503 and describe what the display is doing before booking anything.
