What the F152 error code actually means

Your GE dishwasher has detected that the internal switch responsible for turning the heating element on and off is stuck in the on position, which prevents the dishwasher from properly controlling water temperature. The dishwasher flagged this as a safety concern and stopped normal operation. Restarting the dishwasher or updating its software may resolve the issue, but if the error keeps coming back, the main control board will likely need to be replaced.

Questions people ask 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.
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 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.
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.
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.
