Bosch Dishwasher Error Code F14

F14 on a Bosch dishwasher indicates a water intake fault in which the heater pressure switch detected no or insufficient water pressure at the circulation pump during the heating step of a cycle. The dishwasher stops the cycle as a protective measure to prevent damage from running the pump or heater without adequate water. Common causes include excessive foam, clogged filters, and low water fill levels.

You should not continue running the dishwasher while the F14 error is active. The code indicates the machine has already stopped the cycle because it could not confirm a safe water level at the circulation pump. Running the pump or heater without enough water can cause overheating or component damage. Resolve the underlying cause before attempting another wash cycle.

A reset may clear the error code temporarily, but if the underlying cause has not been addressed, F14 will return during the next heating cycle. To reset the dishwasher, you can turn it off at the power source for a few minutes and then restart it. However, this should only be done after you have inspected and cleaned the filters, checked for foam, and confirmed the water supply is adequate.

Start by cleaning the tub filters at the base of the dishwasher and checking for excessive foam or suds inside the tub. Make sure you are using the correct type and amount of dishwasher detergent and that your rinse aid dispenser is set appropriately. Confirm that the household water supply is fully open and the inlet hose is not kinked. If these steps do not clear the fault, the inlet valve or heater pressure switch may need professional inspection.

If the fault is caused by clogged filters or incorrect detergent use, there is no parts cost involved. If the water inlet valve needs replacement, parts and labor typically range from around $100 to $250 depending on the specific model and service rates in your area. A faulty heater pressure switch replacement can fall in a similar cost range. Getting a diagnostic visit from a certified technician will give you a more accurate estimate.
