I have a dead GFCI outlet. Called electrician. Assessment lose connection or broken wire somewhere between breaker box and GFCI outlet. Since this outlet is in kitchen and wires are running behind tile wall I don’t want to damage the tiling. What should be the step by step process to find where the fault is in path from Breaker to
GFCI?

How old is the house? Before the 70s they would sometimes have other
loads on the kitchen circuits. Trader is right, look for any other
load on that circuit that either works with the breaker on, not off or
that is dead. Look in that box for a bad connection. Other than that
it might be easier to fish in a new wire.
Wires VERY seldom fail. Isolate what outlets are on the breaker in
question. Check connections in all boxes on the circuit. Connect a
lamp socket to the wires in place of the GFCI to tell when the circuit
is live. If you need to check actual conductos, detach them from the
breaker and connect all 3 conductoes together at the service box, then
check continuity at the box from wire to wire. If you have
connectivity neutral to ground and not neutral to live or white to
live you KNOW the problem is on the Live wire. Pretty easy to pin it
down.
