any ideas on how to lock a non locking dishwasher?

I might recommend simply attaching reasonably strong magnets that would add enough resistance to the door that it would be difficult to open.

It would probably be rather cheap, and with some superglue, a rather easy installation.

go to ace hardware and ask for help with a "hasp" and the right size screws.

You'll also need a drill bit to drill pilot holes in the sheet metal.

Use either a plastic childproof lock or a padlock.

Before you start drilling holes in your

dishwasher to place a hasp or hinge,

try screwing a piece of wood or metal

under or on the front of the counter and

swing it down in front of the door. Doesn't

have to be long, just enough to block door.

Wal-mart had child proof locks for Appliances i use one for my Fridge cause my Two year old like to get into the eggs and pretend they are balls lol

u can fit hinges on the dishwasher and put a lock

sorry but discipline is the answer!! not babysitting the dishwasher but discipline....it really works its just that your son has you all figured out!! if you tape it he'll just out smart that too you could probably buy some sort of device to lock it but once again he will sooner or later out smart that as well...not to mention when you use a lock it usually just gives your child something new to play with....discipline!! gate off the kitchen or just discipline his ***! oh and yes i have kids and have worked for years in behavioral health with teens also......

Put a baby gate across the kitchen entry.
