What F152 means on a GE dishwasher

The F152 error code on a GE dishwasher indicates that the control board has detected a stuck heater relay. The heater relay is an internal component of the main control board that switches power to the wash heater element on and off during the appropriate cycle phases. When the control detects that this relay is not releasing or is conducting continuously outside of the commanded heating period, it triggers the F152 fault to protect against uncontrolled heating, which could damage the dishwasher or create a safety hazard.

A stuck relay can occur in a closed position, meaning it continues to pass current to the heater even when the control has commanded the heating to stop. This condition is flagged by the control's internal monitoring logic, which compares the commanded state of the relay against the actual thermal or circuit feedback. The most common root cause is a failed relay on the control board itself, where the relay contacts have welded together due to arcing or excessive current events. Software anomalies can also cause the control to misread relay state, which is why a power cycle and software update are the first recommended steps.

Because the relay is integrated into the main control board assembly rather than being a standalone serviceable component, resolving a confirmed stuck relay typically requires full control board replacement. If the fault clears after a power cycle or software update and does not return, no further action is needed. Recurring faults after those steps point directly to a failed control board.

Common causes of F152

  1. 01

    Welded or fused heater relay contacts on the control board

    Part replacement

    The relay contacts inside the control board can weld together after an arcing or overcurrent event, causing the relay to remain closed and continuously energize the heater. This is the most common hardware cause and requires control board replacement.

  2. 02

    Transient software or firmware glitch

    Wiring / connection

    The control's monitoring logic can occasionally misinterpret relay state due to a temporary software error. A power cycle clears the fault memory and resets the control, and an available software update may correct the underlying logic issue.

  3. 03

    Control board software running an outdated version

    Wiring / connection

    Older firmware versions may have known bugs affecting relay state detection or reporting. Updating the dishwasher software through the GE service update procedure is recommended before condemning the board.

  4. 04

    Failed main control board

    Part replacement

    If power cycling and software updates do not clear the fault, the control board itself has a hardware failure in the relay circuit. Replacement of the control board is the required repair at this stage.

Frequently asked questions about F152

What does F152 mean on a GE dishwasher?
F152 means the control board has detected a stuck heater relay, which is the internal switch that controls power to the dishwasher's heating element. The control flagged this condition because the relay appears to be conducting continuously rather than turning off as commanded. This fault is designed to prevent uncontrolled or unintended heating during the wash cycle.
Will resetting my GE dishwasher clear the F152 error?
A power cycle, which involves cutting power to the dishwasher for several minutes and then restoring it, is the first recommended step and may clear the fault if it was caused by a temporary software glitch. If the F152 code returns after the reset, the control board likely has a hardware failure and will need to be replaced. A software update should also be performed if one is available before concluding the board has failed.
Is it safe to use my GE dishwasher when the F152 code is showing?
The F152 fault indicates a potential issue with uncontrolled heating, which means the dishwasher may not safely regulate the heater during operation. It is best to avoid running cycles until the fault has been diagnosed and resolved. Continuing to operate the appliance with a confirmed stuck relay could cause overheating or other damage.
How do I fix the F152 error on my GE dishwasher?
Start by cutting power to the dishwasher at the breaker for a few minutes, then restore power and check if the fault has cleared. Next, check whether a software update is available for your model and apply it if so. If the F152 error returns after both of those steps, the main control board needs to be replaced, as the heater relay inside it has most likely failed.
How much does it cost to fix a GE dishwasher F152 error?
If the fault clears with a power cycle or software update, there is no parts cost involved. If the control board needs replacement, parts and labor typically range from around $150 to $350 or more depending on the specific model and local labor rates. Getting a diagnosis confirmed before purchasing parts is advisable to avoid unnecessary expense.
