What this code means

The dishwasher reports unusually hot vent air during drying.

Model check: Code meanings and procedures can vary by model family and market. Record the full model number before ordering parts or following a model-specific reset sequence.

Safe checks to start with

  1. Stop the cycle, allow cooling, and make sure vent paths are unobstructed.
  2. Inspect only user-accessible areas described in the owner manual.
  3. After correcting an obvious external issue, restart the appliance once and see whether the code returns.
  4. If you see smoke, arcing, a burning smell, active leaking, gas odour or uncontrolled heating, stop using the appliance and isolate the relevant utility if safe.
