GE Profile Dishwasher 1H Display: Exiting the Settings... | appliancefaults.com

Technical Background:

The 1H error often indicates a communication issue or unintended state within the dishwasher's main control unit (MCU). The MCU uses low-voltage DC signals to interpret button presses and control various functions. Voltage fluctuations or software glitches can disrupt this process, leading to errors.

Symptoms:

The GE Profile dishwasher displays '1H' and seems stuck in the settings menu. The user is unable to initiate a wash cycle or change settings.

Possible Causes:

Incorrect button sequence for exiting the settings menu.
Control panel malfunction causing unintended menu navigation.
Software glitch or corruption within the dishwasher's MCU.
Low voltage to the control panel, causing erratic behavior.
A stuck or shorted button on the control panel.

Solution:

1

Disconnect power to the dishwasher at the breaker panel for 5 minutes. This forces a system reset.
2

Reapply power and observe if the 1H error persists.
3

Press and hold the 'Start/Reset' button for 3 seconds to attempt a manual reset.
4

Consult the user manual for the specific button combination to exit the settings menu (usually involves holding two buttons simultaneously).
5

If the error continues, inspect the control panel ribbon cable for damage or loose connections. Use a 1/4-inch nut driver to gently tighten any screws.
6

Check the voltage at the control panel with a multimeter. You should measure approximately 120V AC.
7

If all else fails, the control board might need replacement. Order the correct part number for your GE Profile model.

Safety Warning:

Always disconnect power to the dishwasher at the breaker panel before performing any troubleshooting or repairs. Lock Out/Tag Out (LOTO) procedures should be followed. High voltage is present within the appliance.

Prevention:

Regularly clean the control panel with a damp cloth to prevent debris buildup around buttons. Avoid using excessive force when pressing buttons. Periodically check and tighten any accessible screws on the control panel.

Expert Tip:

Entering service mode on GE dishwashers usually involves pressing a specific sequence of buttons like 'High Temp Scrub,' 'Heated Dry,' 'High Temp Scrub,' 'Heated Dry' within a 5-second window. This allows you to run diagnostics and clear error codes. Consult your service manual for the exact procedure for your model.

Frequently Asked Questions

•Where can I find the tech sheet or service manual for my GE Profile dishwasher?

The tech sheet is often located behind the lower access panel, usually folded up and taped to the frame. You can also find it online by searching for your model number followed by 'service manual' or 'tech sheet'.

•How do I test the individual buttons on the control panel to see if one is stuck or shorted?

Using a multimeter in continuity mode, carefully probe the connections on the control board associated with each button. Pressing a button should complete the circuit and show continuity. A stuck button will show continuity even when not pressed.

•What is the typical cost to replace the control board on a GE Profile dishwasher?

The cost of a replacement control board varies depending on the model but typically ranges from $150 to $350 for the part itself. Labor costs for professional installation can add another $100 to $200.
