No power to the dishwasher
Make sure there's power getting to the dishwasher. Check for a
tripped circuit breaker or a blown fuse. Check the wall socket for
power. Sometimes the power cord disconnects at the dishwasher (inside
the junction box, behind the bottom kick panel), if this is the case,
the wiring must be repaired or replaced.
