We had a mishap with our dishwasher while rounding an unexpected curve a bit too fast. The drawer came open and broke the end piece on one of the rails. We had locked the drawer but didn't realize the lock wasn't designed to hold if the power to the coach was interrupted. The following is the inf. I received from Entegra.
Every time the customer locks the dishwasher they should immediately shut off the dishwasher breaker above the drivers seat.
-This will insure the lock function stays in place while the customer travels.
-There is not a “lock” on the dishwasher.
-The dishwasher locks by vacuum seal.
-If the customer locks the dishwasher and somehow power fluctuates, it will default to “ready mode” and will no longer be locked.
-This may happen when the customer disconnects from shore power or starts the coach.
PS Don't forget to flip the breaker back on when you are stationary :)
