Bosch Refrigerator Error Code F50

F50 is a waste water alarm indicating that the safety electrodes on the ice maker base have detected water continuously for more than 10 minutes. This tells the control board that water is not draining away from the ice maker as it should. The most common causes are a frozen water outlet, a failed waste water pump, or an installation issue preventing proper drainage.

A reset may temporarily clear the F50 code from the display, but it will return if the underlying drainage problem is not resolved. The alarm is triggered by a physical condition detected by the safety electrodes, so the fault will reappear within minutes if water continues to accumulate on the ice maker base.

Repair costs depend on the root cause. If the issue is a frozen outlet or leveling adjustment, costs may be minimal, primarily covering a service call in the range of $75 to $150. If the waste water pump needs replacement, parts and labor together typically run between $150 and $350, depending on your location and service provider.

Start by checking the ice maker's water outlet for ice blockage and defrost it if frozen. Then confirm the waste water pump is running and not obstructed. Verify that the refrigerator is properly leveled and that the drain line is not kinked or clogged. If the electrodes are coated with mineral deposits, clean them and recheck whether the fault returns.

Yes, persistent water accumulation in the ice maker base can lead to water leaking onto the floor, potential electrical issues near the pump and electrodes, and damage to surrounding cabinetry or flooring. Addressing the fault promptly is recommended to prevent water damage from progressing.
