Bosch Dishwasher Error Code E3

E3 on a Bosch dishwasher is a filling error code. It means the control board started a fill cycle but did not receive confirmation from the flow meter or pressure switch that the tub reached the required water level within the expected time. The dishwasher stops the cycle to prevent running with insufficient water.

No, the dishwasher will not complete a wash cycle with E3 active because it stops filling and halts operation to prevent running the wash pump without adequate water. Attempting to restart the cycle repeatedly without resolving the fill issue will not bypass the error and risks pump damage if any water does enter but falls short of safe operating levels.

A reset, typically performed by pressing and holding the Start button for 3 to 5 seconds or cutting power to the unit, will clear the active error and allow the dishwasher to attempt a new fill cycle. However, E3 will return immediately if the underlying cause has not been fixed. A reset is useful for confirming whether the error is intermittent or consistent, but it does not repair the fill system.

Start by checking the water supply valve under the sink to confirm it is fully open. Then inspect the inlet hose for kinks or obstructions. If the supply side looks normal, the next step is testing the water inlet valve for continuity and checking whether it opens fully when energized. If the valve and supply are working correctly, the flow meter or pressure switch may need to be replaced.

If the cause is a closed supply valve or kinked hose, there is no parts cost. A replacement water inlet valve for a Bosch dishwasher typically costs between $25 and $75 for the part, and a flow meter or pressure switch runs $20 to $60. Professional labor for a dishwasher water inlet repair generally adds $100 to $200 depending on your area. Homeowners comfortable with appliance repair can replace the inlet valve or flow meter themselves using basic tools.
