My Samsung dishwasher has code PE I shut the breaker off and on no change machine sounds as if trying to start then code PE starts flashing again.

SOURCE: "PE" error message on LG Dishwasher LD-12AS1 LD-12AW2

The PE error code indicates that the machine has a water pressure sensing error. Check and clean the filters on both sides of the inlet water line. Good luck!

SOURCE: Start light flashing

start light on and no other action could mean that the door catch has gone faulty, test accordingly and replace if needed, no wash cycle will work if this item is faulty, the waste outlet pump may be the only part that will work on some models, this is a safety feature hope i have helped if so please rate me, work safe unplug when testing

That means the control sensed that the heater in the d/w did not operate 3 times in a row. so the unit locks out. First remove the kick plate and you may have to pull the unit out from under the cab, but check your heater. use a meter to see if it reads open, if so order a heater assy it will come with a new control replace it to. If your heater checks good press in sequence normal wash , heat dry ,normal wash,heat dry , normal wash , heat dry three times within 6 sec all the lights will come on then hit cancel. What that did is reset the control and clear that fault. Keep in mind that d/w does not heat it's own water your incoming water temp should be 120. the d/w will maintain that temp. when starting your d/w first turn on your hot water till it gets hot then start your d/w this insures your unit fills with hot water and not cold

1) Turn off the breaker to the machine.

2) Wait 30 seconds and then turn it back on.

3) All the lights will be flashing. At this point turn the dial to "rinse only" and then press "Heat dry" and "Start/Cancel" at the same time.

4) The Machine will go into maintenance mode going through all the cycles quickly.

5) After this is finished the problem should be solved.
