Importance of taking pictures
Combo52, I am glad you are taking pictures of neglected appliances. Many of the saved pictures may never come to use, but sometimes they do...
In my case, I was called out to a large corporation that had recurrent failures with video products, primarily due to overheating. As I was in charge of quality at that time for the manufacturer, I had to show up to investigate. As the job was large, I went with a colleague.
The air filters on many units were so clogged you had to wipe the cabinet clean before you could actually see the filter, and of course it was clogged beyond belief.
We brought the staff in and showed them the trouble. To our face they denied neglect of maintenance. We advised them we are taking pictures, notes and putting it in a permanent file. They must change their maintenance practices or they will face big repair bills. Bear in mind, we were the manufacturer and were also advising that their warranty may be cancelled.
About a year later I get a call. Same corporation - different person. Complaint: Overheating and yellowing of the image. Of course the quality of the product was called into question.
I asked the person how long they worked for the company. Less than a year.
After evaluating one sample I had to give them an estimate for neglect repairs. I shared the pictures. I gave them a thumbnail estimate in the hundreds of thousands of dollars. However, we had a RECORDED history of neglect and we were not sued. The client went away and that was ok. Our attitude is that we did not want our brand in any facility where they did not perform perfectly - and that was not going to happen there due to neglect.
Although no safety issue existed in my case, dryer fires scream for picture taking in cases of neglect or installation / usage errors. The one time it saves your butt will pay for all the SD cards you've ever purchased... and more.
