Bosch Dishwasher Error Codes

Bosch Dishwasher Error Codes explained in plain words: what the display says, the safe thing to try first, and when to book a technician.

These six codes have their own self-help pages or articles on Bosch’s US site. Bosch’s list covers many more codes, but its overview page gives no meanings, so we left them out.

Codes vary by model: check your manual or the model label.

Before you try anything: switch the appliance off and unplug it, or turn off its breaker, before you touch a hose, filter or panel. Do not open the control board or electronics, and never bypass a safety switch, lock or thermostat to get past a code.

Bosch Dishwasher Error Codes: what each one means

E15

• What the manufacturer says: The safety switch has detected water in the base of the dishwasher, and the leakage protection has activated.
• One safe thing to try: Stop the water flowing into the dishwasher, as Bosch says.
• Book a technician when: straight away. Bosch says to contact Bosch Customer Support at 1-800-944-2904 after shutting off the water.

E16

• What the manufacturer says: An issue with water flowing into the dishwasher or the filling system.
• One safe thing to try: Check the inlet hose is not kinked or damaged.
• Book a technician when: the hose is fine and the code remains.

E17

• What the manufacturer says: An issue with water flowing into the dishwasher or the filling system. Bosch gives the same advice as for E16.
• One safe thing to try: Check the inlet hose is not kinked or damaged.
• Book a technician when: the hose is fine and the code remains.

E22

• What the manufacturer says: The dishwasher filter is blocked.
• One safe thing to try: Take out the filter at the bottom, rinse it under running water, scrub with mild soap and a soft brush, and put it back.
• Book a technician when: the code returns after a clean filter.

E24

• What the manufacturer says: The dishwasher is not draining properly because of a blocked drain filter. Bosch lists a blocked hose or a dirty filter as causes.
• One safe thing to try: Check the hose is not kinked, the siphon connection is sealed and the pump cover under the filter is not loose. If the drain connects to a garbage disposal, check the disposal’s drain plug was removed.
• Book a technician when: these checks do not clear it. Bosch says to call customer service.

E25

• What the manufacturer says: The drain pump is blocked, or the drain pump cover is loose or missing.
• One safe thing to try: Take the filter out and check the pump cover under it is secure. Bosch shows how to clear debris, which can be sharp, so use caution and gloves.
• Book a technician when: the code remains after a clean pump area and a secure cover.
