What Solid Red Light usually points to

•The code severity on the main page is critical, which should shape how quickly you escalate.
•Look at whether the symptom is consistent, intermittent, or clearly tied to one stage of operation.

•Remove bin, clean brush bar of all hair and debris

•If the simplest checks fail, compare the repair range with the age and condition of the appliance or vehicle.
