Bosch Dishwasher Error Code E:19

E:19 indicates a loose or faulty wire harness connected to the detergent dispenser actuator, or a failed dispenser actuator itself. The power module monitors this circuit and logs E:19 when it cannot communicate reliably with the actuator. This fault can prevent the soap dispenser from opening at the correct point in the wash cycle.

The E:19 error is not typically a safety hazard in terms of electrical shock or fire risk, but running the dishwasher with this fault means your detergent may not dispense correctly. This results in poorly cleaned dishes and can lead to hygiene concerns. It is best to diagnose and resolve the issue before continuing regular use.

If the issue is simply a loose connector, there may be no parts cost at all, just the time for diagnosis. A replacement wiring harness typically runs in the range of $20 to $60 in parts. A new dispenser actuator generally costs between $30 and $90 depending on the specific model, with additional labor costs if a technician is hired for the repair.

In many cases, yes. Start by inspecting the wire harnesses between the rinse aid dispenser, the dispenser actuator, and the power module for loose connectors or visible damage. Reseating a loose connector may clear the fault without any parts replacement. If the harness is corroded or damaged, or if the actuator itself has failed, replacement parts will be needed.

A reset may temporarily clear the E:19 code, but if the underlying wiring or actuator issue is not resolved, the error will return during the next cycle. A reset should only be used after completing the inspection and addressing any loose, corroded, or damaged connections.
