Best way to find a slow leak in Bosch Dishwasher?

Hello,
after each wash, our Bosch SHU-9925 accumulates about 2 cups of brown water in the base, setting of the Aquastop switch.

Drying the base pan with a towel from the front dries it up enough to start it again. (for only one wash though)

The unit is built in and pulling it out will be very cumbersome. Can somebody give us some advice on what leaks are typical, so that we can search more efficiently,please

Also anything that can be tackled from the front would be great.

PS. One other thing we noticed is a burnt, plastic smell that the unit puts out during the wash cycle. It’s kind of faint, but clearly noticable.

Any suggestions would be great. The wife is after me to get that fixed and I stuck my head out saying I could do it…
Thanks
Chip

you can remove the front panel and lower toe panel… lay down and watch it run… 80 percent of the repairs for this it must be pulled…

Thank You! Any advice on where leaks like this could show up? What should we look for?
