the dishwasher is about four years old frigidaire electronic p/n:154459001 the lights are flashing 6hr delay, washing, drying, sanatizes, and clean all blinking, I reset the circuit breaker it started washing and then draining, works for about 15 mins then stops and lights blink again:mad:

Part number doesn't do us any good give us a model number.....look at your tech sheet under the bottom panel or in the front panel just unscrew the screws on the cover and look behind it......your tech sheet should show you how to put it in diagnostic mode and test the unit.....should have a series of blinking lights if you have a problem...copy down the series of blinking lights in most cases it blinks 6 times then 3 times......copy each code down and to advance through the cycles and get more codes you press start........also another trick.....turn off the breaker disconnect the ribbon going from the touchpad to the main board....turn the power back on and close the door you should hear the drain pump start within a couple minutes.......if the drain pump doesn't activate it's usually the main board that's bad since you say all the components are working right for 30 minutes...but if the drain pump does come on after that then i'd suspect the touchpad is fouling out........Also the fact that it happends 30 minutes later you might want to check your heat element make sure you have 50 ohms or less in a continuity test and if you have an amp clamp, clamp one of the wires going to it while it's running and while it heats you should have around 8 amps............you can test the heating element amperage also while your going through diagnostic it may be quicker to have it come on then sit the whole time through...
