GE Dishwasher 1H Display Issue: Changing to Minutes... | appliancefaults.com

Technical Background:

The 1H error on GE dishwashers often relates to a communication error or software glitch within the Microcontroller Unit (MCU) on the main control board. The display functions are controlled by the user interface board, which receives instructions from the main control board. Voltage irregularities or corrupted data can interfere with proper display operation.

Symptoms:

The GE dishwasher is displaying the error code '1H' and the homeowner wants to change the display to show the minutes remaining in the wash cycle instead of another format.

Possible Causes:

Incorrect display setting selected.
Corrupted software or firmware.
Faulty user interface control board.
Problem with the main control board MCU.
Voltage fluctuations affecting display functionality.

Solution:

1

Consult the user manual to check for display settings related to showing remaining time. Some models allow switching between different display modes.
2

Perform a hard reset of the dishwasher by turning off the breaker for 5 minutes, then turning it back on. This can sometimes clear temporary software glitches.
3

Check the ribbon cable connection between the user interface control board and the main control board. Ensure it is properly seated and free from damage.
4

If the dishwasher is connected to a surge protector, remove it and plug the dishwasher directly into the outlet. Test the outlet with a multimeter; it should read approximately 120V AC.
5

Consider a software update or firmware re-flash, if available. Check the GE website or contact GE support for information on how to update the software.
6

As a last resort, replacing the user interface control board or the main control board might be necessary. This requires licensed technician diagnosis and replacement with the correct part.

Safety Warning:

Disconnect power to the dishwasher at the breaker panel before performing any diagnostic or repair procedures. Use Lock-Out/Tag-Out (LOTO) procedures. Be aware of high voltage components inside the control panel. Do not touch any components with wet hands.

Prevention:

Use a high-quality surge protector to protect the dishwasher's electronic components from voltage spikes. Avoid overloading the circuit that the dishwasher is connected to. Periodically check for software updates.

Expert Tip:

Some GE dishwashers have a hidden service mode. To access it, press and hold the Start and Cycle Select buttons simultaneously for 5 seconds. This can allow you to run diagnostic tests and reset certain settings.
