I ran into this when I was about to repair a 2007 front loading washer which needed a door seal.  A small matter of taking off the retaining spring and putting it back on over the  new seal.

It turns out I could not buy a door seal!  Why? Because @LG has (unlike any other company) said this was “a critical part” and needed service by “an official repairman”.  Liabilities hidden and otherwise given as reason.  They gave me the name and number of a local repair man who said “I have never done one of those”

Very similar happened on a microwave that needed the insert of a new circuit board. A very straight forward, easy thing to do; easily accessable.  Especially when the microwave was owned by an IT leader.  Again, they would not sell him the boad but directed him to an “official repairman” for several hundred dollars as this was considered a “security issue”

Planned obselense taken to a new level by LG!  This is the only company to go to this extreme that I am aware of.  This of this if  you are planning the lower priced LG product  as a purchase.
