A numbered error code on a Thermador appliance can mean very different things depending on the platform: a dishwasher’s E22 drainage code has a documented, specific cause, while a range or oven’s generic “E” code is often a starting point for a hands-on diagnostic rather than a single fixed answer. Our technicians confirm which situation applies before touching anything, testing igniters, sensors, pumps, and control-board communication directly rather than assuming the most commonly-blamed part is the culprit.
That confirmation step is what keeps repairs to a single visit: the part we order and install is the part we’ve already proven is the cause.
