I have a probe I got from Todds site. I have used it 20-25 times and it was getting a little nasty so I put it in the dishwasher to see what would happen.
It got clean and read the temp of the dishwasher the whole time. Without putting it under water I don’t think you can get it any wetter than in the dishwasher set to pans, hot wash, Hot dry and sanitize. I did have it at a upward angle stuck though a q-mat.
Still a little stained and you can see the dark area that was in the door but it's clean and still works. It took 2 1/2 hrs in the dishwasher and never blinked.
I do not believe the whole moisture in the probe problem. I have taken two apart to fix the crimps and both were sealed inside pretty good.
I can see if you immerse the probe under whatever liquid for a period of time than fluid could seep in and short out the probe. Spritzing, washing, dipping in the sink, and rinsing off I see no problem.
I have not sealed any of my probes and after this experiment I won’t in the future and I won’t be scared to get them wet.
I believe the failure problem is mostly for the BBQ probe because it is exposed to faster hotter temp swings and the crimps expand. If the food probe is used for pit temps then that would be exposed to the same swings and failure.
Just like Maverick I do not recommend any one doing this or getting your probes wet in any way. JTCMA.
From now on I will be using the dishwasher but that’s just me.
