Bosch Dishwasher Error Code E:6102

E:6102 indicates that the drain pump is blocked or that the drain pump cover in the sump is missing or loose. The dishwasher shuts down at the end of the program as a protective measure to prevent pump motor damage. The two most common causes are a foreign object jammed in the pump impeller and an improperly seated pump cover. Addressing either of those issues typically clears the fault.

You should not continue running the dishwasher while this error is active. The code means the drain pump cannot operate correctly, which can leave standing water in the tub and may cause the pump motor to overheat if forced to run against a blockage. Resolve the underlying cause before starting another cycle.

If the fix is simply removing a foreign object or reseating the pump cover, there may be no parts cost at all, just your time. A replacement drain pump cover is a low-cost part, typically in the range of $10 to $30. If the drain pump motor has failed and needs replacement, parts and labor combined can range from $150 to $350 depending on your location and the specific model.

Start by removing the lower spray arm and the filter assembly to access the sump at the bottom of the tub. Check that the drain pump cover is present and snapped firmly into place, then remove the cover and inspect the pump impeller for any foreign objects such as glass, pits, or debris. Clear any obstructions and confirm the impeller spins freely before reassembling and running a short cycle to test.

A reset may temporarily clear the code from the display, but the error will return if the root cause has not been fixed. The pump cover must be properly secured and any blockage in the impeller must be removed for the fault to stay cleared. Address the physical cause first, then reset the machine.
