Had a similar issue with my Gaggenau steam oven last year — super frustrating and not a lot of techs really know how to deal with them. Reading this, everything sounds spot on. Wish I had found you guys back then! Definitely saving your info in case it happens again.
Impressive work diagnosing and fixing the issue efficiently! Instead of jumping to costly replacements, your methodical approach saved the client money while delivering a lasting solution. This is the kind of expertise that sets great repair teams apart!
