H5i water tub in dishwasher?

I'm wondering does the Cascade detergent or any of them affect the water tub? Does it ruin the metal part?

Also, do you run the dishwasher with just this water tub in it? I'm thinking if I put it in with dishes,even though I clean the dishes first, wouldn't the food or greasiness contaminated the water tub? Maybe I'm getting a little OCD???
Do you put the dishwasher on "sanitize"? Do you let the dishwasher's heater dry it or do you air dry it?

Yes, you can put the tank in the dishwasher - top shelf only.

I don't put my stuff in the dishwasher - but that's just me. I'm already washing other CPAP paraphernalia, so it's just as easy to pull the tank apart and wash everything by hand.

I've washed my Respironics tubs for 7 years or so now. Some of my older tubs look a little worse for the wear after years of washing, but they all still work fine. Some slightly less shiny aluminum and very slightly less clear plastic.

I suspect if I replaced a tank yearly, I wouldn't be able to see any difference between old and new.

I wash CPAP mask parts and tanks weekly on the hottest, longest cycle my dishwasher does. I usually skip the heated dry cycle. I always wash CPAP parts separately from dishes.

I do have spares of everything, and wash on alternate weeks, so each set only gets washed every two weeks. I let the just washed set dry for a week.

Washing hoses is problematical because water would sit in the hose and not drain out between cycles, so I usually don't wash the hose in the washer.

I don't wash headgear, and some masks have parts I wouldn't wash.

I say you need a spare tub and mask anyway. Figure out when your insurance will buy spare mask parts and tubs and get a few spares. Get a spare, and wash one of the parts. Inspect carefully. Unless it turns the tub or mask into some undetectable reservoir of deadly bacteria or dishwashing chemicals, at worst, you're out the cost of a replacement tub or mask part.

Balance the risk of dishwasher damage vs. the value of having a really clean mask and tub.
