Quick check — and when it's not DIY
Before booking a repair, check whether the error only appears during a specific cycle or setting, which narrows down the fault. Also, note the exact error code or light pattern, then try a full power cycle — unplug for 60 seconds before doing anything else. If that doesn't fix it, if the code comes back, it's pointing to an internal board or sensor fault, and diagnosing that correctly needs the specific service manual for your model.
