— Bosch Home Appliances US, Dishwasher Error Codes | Support | Bosch. Codes vary by model: check your dishwasher’s own manual.
The same code can also show as: E6002.
In plain words, E21 is about the heating circuit — an element, a relay or a safety limit in the heating path.
Bosch gives 5 other heating circuit codes for this dishwasher: E01 (There is a heat pump motor circuit fault at the main control board), E04 (Appliance has detected faulty (heater) electronics in the self-test), E09 (There is a heat pump internal heater fault/error), E10 (There is a Zeolite (Crystal Dry) chamber heater fault/error), E12 (There is limescale build-up in the heat pump).
Next to E21 in Bosch’s table: E19 (There is a detergent dispenser solenoid circuit fault/error) and E22 (The dishwasher filter is blocked).
Safety: If it smells like burning, sparks, or trips the breaker, switch it off at the breaker and leave it off until it is checked.
At least THIS WEEK. fixRAgent treats this code as a this-week repair: the appliance has reported a fault, but the code alone does not point at a safety hazard. This is fixRAgent’s reading, not the manufacturer’s. A photo can raise it — water near wiring, scorch marks, a gas smell — but a code never lowers what the photo shows.
Appliance repair. Have the model and serial numbers from the label ready — a photo of the label works.
Check whether your model is under a safety recall on the U.S. Consumer Product Safety Commission’s site: cpsc.gov/Recalls. Your owner’s manual is on Bosch’s support site; search it with the model number from the label.
