Bosch Dishwasher Error Code Wash

The Wash indicator on a Bosch dishwasher means the appliance has detected that the door is open or is not locking properly. The control board requires a confirmed door-closed signal from the door switch before it will allow any cycle to begin. This is a built-in safety feature to prevent water from being pumped into an unsecured tub. The issue may be as simple as the door not being pushed shut fully, or it could point to a faulty latch, switch, or lock solenoid.

No, the dishwasher will not operate while this error is active, which is intentional. Running a dishwasher with an unsecured door could allow hot water to leak onto the floor. Do not attempt to bypass the door lock system. Address the underlying cause of the error before resuming use.

The cost to repair a Bosch dishwasher door latch typically ranges from around $75 to $200, depending on whether you do the repair yourself or hire a technician. The door latch and switch assembly part alone generally falls in the $20 to $80 range. Professional labor adds to that cost depending on local rates and the time required to access and replace the component.

Start by making sure the door is pushed completely closed and that nothing inside the tub is blocking it from sealing. Check the door latch for visible cracks or wear and confirm that it clicks firmly into the strike plate. If the latch looks intact, the door switch should be tested for continuity with the door closed. A failed switch or latch assembly will need to be replaced to clear the error.

A reset may temporarily clear the display, but if the door latch or switch is physically faulty, the error will return as soon as a new cycle is attempted. A reset is useful to rule out a one-time control glitch, but it is not a fix for a mechanical or electrical fault in the door lock system. If the error reappears after a reset, proceed with inspecting the latch and door switch.
