The handle is broken on the inside. Put your thumbs on top and pull out with them while pushing the handle up and in. With a little luck it will open for you.
A 15 amp dedicated circuit breaker should be used for the dishwasher. The disposal can be wired to the general kitchen 15 amp circuit.

No, this isn't necessary. The circuit breaker protects your home by avoiding an overcharging caused by a short-circuit. It's advisable blocking the access to the breaker.
A trip free circuit breaker is one that will disconnect a circuit even if the manual switch is held at the "on" position. It is a safety feature to prevent a circuit breaker being disabled either deliberately or accidentally.
The problem may not be the dishwasher. All dishwashers should be on its own 20 amp breaker and hard wired. Even portable units that use a plug should be on its own circuit line but often not. If the dishwasher is tied into other appliances or plugs, it can over load and trip the breaker. If this is the only you can run the dishwasher, shut the breaker off and see what else is turned off and avoid leaving them on while dishwasher is running. Hopefully itβs not the refrigerator!
If the circuit breaker is in the off position there is no need of overload protection. Overload protection monitors the load amperage, If there is no amperage through the circuit there is nothing to monitor.
No, the dishwasher uses the dedicated breaker in the distribution panel, that feeds the device to protect the circuit, should a fault occur.
Turning the breaker on allows the power to flow through to the outlets, lights, and appliances on that circuit, so yes power goes to and through a turned on breaker. If the breaker is off, but the main power is on, power still get to the breaker, usually from the bus bar that runs down the middle of the back of the breaker box.
A circuit breaker has a small handle that will flip to the open position due to overload.
