Studying and learning has no value until it is applied It is necessary to follow a step-by-step procedure to diagnose a
machine malfunction
For example, let us assume we have selected a "Normal Wash" and the dishwasher will not fill. A rule is to always check
the easy and obvious first
1, is there power to the machine? Be sure the proper connection been has made to the electrical supply, Also check
for a tripped circuit breaker or blown fuse
2. Make sure the water supply to the machine is turned on,
3, Check to be certain the door latch is closed,
4, Check to be certain the timer dial has been advanced to the point where the indicator light comes on A short
delay will be present before the machine begins to fill,
5, Check the float to be sure it is not stuck, it must move freely
