GE Dishwasher 1H Display: How to Cancel Delay Start... | appliancefaults.com

Technical Background:

The 1H error code on GE dishwashers, particularly Model 2025, often relates to the delay start function or communication issues within the machine's control system. The Main Control Unit (MCU) manages the delay start timing and communicates with the user interface. Incorrect or corrupt signals can cause the 1H error. Voltage fluctuations can also interrupt the MCU's program.

Symptoms:

The GE dishwasher Model 2025 displays '1H' on the control panel. The dishwasher is in delay start mode and the user wants to cancel it, but the standard button presses are not working. The dishwasher does not respond to regular commands.

Possible Causes:

Incorrect button sequence to cancel delay start.
Faulty control panel buttons.
Software glitch in the main control unit (MCU).
Power interruption during the delay start period.
Corrupted memory in the MCU.
Communication error between the control panel and the MCU.

Solution:

1

Press and HOLD the START/RESET button for 3 seconds to attempt a manual reset.
2

If the display still shows '1H', try pressing the DELAY START button repeatedly until the delay time is set to '0'.
3

Disconnect power to the dishwasher at the breaker panel for 5 minutes. This will reset the MCU.
4

Inspect the control panel ribbon cable connection to the MCU for corrosion or damage.
5

Using a multimeter, check the voltage to the MCU at the power input connector. You should measure approximately 120V AC.
6

If the above steps fail, the MCU may need to be replaced. Consult the service manual for the correct replacement part number.
7

After replacing the MCU, perform a diagnostic cycle to ensure proper operation.

Safety Warning:

Always disconnect power to the dishwasher at the breaker panel before performing any repairs. Use Lock-Out/Tag-Out (LOTO) procedures to ensure the breaker remains off. Be aware of high voltage components within the dishwasher.

Prevention:

Regularly clean the control panel with a damp cloth to prevent button stickiness. Avoid power surges by using a surge protector. If the dishwasher is not used for extended periods, disconnect it from the power supply to prevent potential damage from power fluctuations.

Expert Tip:

Some GE dishwashers have a service mode that can be accessed by pressing a specific sequence of buttons (e.g., START/RESET, then DELAY START, then START/RESET again). Consult the service manual for the exact sequence for Model 2025 to access diagnostic codes and perform advanced troubleshooting.

Frequently Asked Questions

•How do I enter service mode on this specific model?

The exact button sequence varies. Typically, it involves pressing START/RESET followed by another button, then START/RESET again. Refer to the GE Model 2025 service manual for the correct sequence.

•Where can I find the service manual for GE dishwasher Model 2025?

You can often find it online through appliance parts websites or by contacting GE directly. Search for 'GE Model 2025 Dishwasher Service Manual'

•If the MCU needs replacing, where is it located and what tools will I need?

The MCU is typically located behind the control panel. You'll likely need a Phillips head screwdriver, a 1/4-inch nut driver, and possibly a small flathead screwdriver to disconnect ribbon cables. Remember to disconnect the power before accessing the MCU.
