Kenmore Dishwasher Error Code 4-5

Error code 4-5 means the control board has detected that the diverter disk in the sump is missing. The diverter disk is a round component at the bottom of the tub that routes water to the spray arms. The dishwasher will not run while this code is active. You will need to inspect the sump area to confirm the disk is installed and properly seated.

The dishwasher will not complete a wash cycle while the 4-5 code is active, as the control halts operation when the diverter disk is not detected. Do not attempt to bypass the fault. Running the machine without a functioning diverter system would result in improper water distribution and poor wash performance.

Resetting the dishwasher by disconnecting power will clear the active fault display, but the code will return as soon as the machine runs a cycle if the underlying issue has not been resolved. The diverter disk must be physically present and correctly installed before the control will allow normal operation to continue.

Start by unplugging the dishwasher or disconnecting power, then remove the lower spray arm, turbo zone assembly, rear feed tube, and outlet cover to access the sump. Visually confirm the round diverter disk is present and properly seated. If the disk is missing, it will need to be replaced. If the disk is in place and the code persists, the diverter motor or its sensor may need to be inspected.

If the diverter disk simply needs to be reseated, there is no parts cost and only your time is involved. If the disk is missing or broken and requires replacement, parts typically range from $15 to $50 depending on the specific model. If the diverter motor has failed, parts and labor combined can range from $100 to $250 or more.
