Pour a cup of bleach in bottom and run it empty.
If the faucet on the sink.can hook up to the dishwasher then yes it can.
Possibly if the housing is big enough.
Fitting for WHAT.
The attachments for portable dishwashers are not universal, and do not fit all faucets. To fix this, a person can buy an attachment for their faucet the matches the dishwasher.
No, it will not.
Get an adaptor
Anything is possible but I doubt it for under $400. It is far easier to go the other way and convert from portable with a manufacturers kit.
The inside of your dishwasher should be cleaned regularly.
NO, definitely not so. I have changed hundreds of dishwashers and never found a case like that.
Yep.
