I have not heard of or seen this dishwasher but I do know on a lot of dishwashers if the water is not hot enough it will heat the water and the heating light will come on to let you know. On most models if the washer has to heat the water it will prolong the wash time. It may do this through out the wash and rince cycles. dont be surprized if your dishwasher runs 90 min or longer. This is normal for most all dishwashers now. I would read the owners guide and get to know whats normal for your unit.
a.1) water never reached the proper fill/run level so the computer prevents the heater from starting and alerts the user. There should be a code list in the troubleshooting section of the user manual describing the blinking lights and what they mean.Solution- verify by sound if water flows at the same rate as the sink tap, if not then shut off the water and check the inside the connection hose for debris against the screen inside the hose end or insid ethe machine end where there is a intake valve. The debris keeps sediment out so it works but there's no auto cleaner for the screen.
a.2) Otherwise the heater itself is faulty meaning it does not conduct an electrical path or maybe overheating (could be dry) and the computer senses the wrong temperature either too high or too low.B-- Now, if you do NOT hear water filling for those first 3 minutes, 3 things could be happening;Solution- A service call to determine the reason why; heater continuity, water valve, heater relay, hi-temp fuse, etc.
b.1) House water supply is turned off.
b.2) hose is clogged (see solution a.1 above)
b.3) Drain pump inside dishwasher was clogged during the last run and old water didn't drain out (maybe some water is evident in the tub bottom).
Solution- Most dishwashers start each wash cycle with 30 second drain pump running to make sure the tub is completely emptied so the next fill cycle can't overfill. This ensures that if the user finds a 3 liter pot that flipped over during the last wash and if they dump that full pot of water into the unit to make it lighter, that the water will get drained before the new water enters the tub.
If the drain pump is clogged reset the power and restart the wash cycle. Note how much water is in the tub and see if it goes down any during those 30 seconds by opening the door afterwards. Find the clog either a bone or plastic bag or some small pice of a childs toy is stuck in the drain pump or the other end is clogged maybe by grease or bones if you have a sink disposal unit. The things they grind up drop into the drain 1" inch above the hole for the dishwasher drain tube.NOTE: There is also an overfill [float] switch if the water inlet valve gets stuck open and the water keeps filling, the drain pump is switched on until someone comes and shuts off the water supply. When the tub drains the float drops and the drainpump stops. This will also make lights blink so check the user manual for codes or call the factory service reps [1-877-337-3639].Either way, there should be instructions to reset the machine for restart. If it doesn't reset you need someone to fix the control that tripped the unit, maybe a safety fuse or a broken piece of the puzzle.
