I've never found a DW with a drip pan. If you want one, have an electrician reroute the power cable.

As stated above, never had a drip pan with a dishwasher!

Here are two drain pans. Note that the pans have only three sides -- necessary because you have to slide the dishwasher in and over the pan. Read the description to understand what they're intended to do. You'd have to move the electrical line or cut a hole in the pan which would defeat its purpose.

Never heard of a dishwasher drip pan.

FWIW, Bosch and Miele DWs have drip pans built into their bases. These have float switches that will close the on-board water intake valve if sufficient water leaks from the machine into the base pan. Other brands may do this, as well.

Fisher & Paykel DishDrawers (which are akin to a 1- or 2-drawer filing cabinet) also have a leak sensor in the base.

Prefab pans are available for washing machines. Not aware of anything aimed at dishwashers but that is not to say they aren't available or could be devised. Although, something add-on, not unitary to the design of the machine, could be a challenge to access for servicing depending on how it's done.

As others have posted, Bosch dishwashers have pans built in along with water alarms that turn off water supply when they sense water. My Bosch washer also has a built in pan with water alarm as well as double coils.

I had pans installed under my refrigerator with a water alarm installed by the plumber or the electrician - don't know which tradesperson did it.

IMO everyone should have a pan with a water alarm shutting off water because floods from dishwashers and refrigerators can cause catastrophic damage. And if your washer in on the second floor or you live in a multi-unit home, they prevent causing significant damage to your home or those below you.

Incredible!

The Fisher-paykel disasters have drip pans and auto shutoffs and they regularly trip them because the things are just unreliable pieces of junk. Without the pans you'd have water all over you kitchen floor.

The problem with the refrigerator is unless you have something that shuts off the leak at the wall when it detects a problem, you're still going to have a disaster when the pan overflows if it's not plumbed away (code here requires such for clothes washers now).

My DishDrawer will be 18 yo next month. Never had any fault codes occur.

I can't comment specifically on the refrigerator but the alarm systems are triggered when they detect water where it shouldn't be so they shut themselves off before the pan is full.

I have an HVAC that is in the ceiing above my foyer and I had a water alarm shut off installed when I remodeled. Prior to that I would have water leaking out when the compressor for some reason produced water or when there was a clog in the water line - HVAC system has a water line that is feeds all of the units on my stack in a high rise. So if it became backed up at any point below me, it would flood as well.

This summer my unit began turning off because it sensed water in the pan - but now there was no flood because it turned off before the pan became filled. I did wind up replacing the unit last week but the alarm shut off certainly saved me from having to deal with replacing the "ceiling" below the unit and possible damage to the wood floors in my foyer.

I've owned homes for almost 50 years and never had a dishwasher leak, so, unless there was a quality alarm and shutoff system that was an integral part of the appliance, I'm not convinced that it's worth the trouble and cost of installing some supplemental system. I do have an $8 battery powered, moisture-sensing alarm sitting on the floor of my laundry room, but that's the extent of my preventative measures.
