Here is a link to one type of dishwasher liner Dishwasherleak
All it does is route the water out in front of the dishwasher so you can see it. Better than nothing but only works if you are home and in the kitchen
I do know water sensors that activate a shut off valve are also available but fairly pricey.
In Europe this is included with quite a few dishwashers re: some Bosch's
I have a GE dishwasher that likes to leak every few years. The soft rubber parts like the sump and hose connectors just seem to rot out. Have replaced all of them (I Hope) in the last 10 years. GE of coarse has never heard of this. I found a fairly large plastic pan and put a drain in the middle of it with a clear plastic hose attached. My kitchen is over my utility room so I just drilled a hole in the floor and routed the hose close to my sewer. A couple times have gone down to do laundry and found water from the hose. I then know it is time to pull the dishwasher apart once again |
