My dishwasher reaches 79 minutes and then stops. It makes this pressure sound like it is going to start but then doesn't.

question edited for clarity
Question moved to Dishwashers

There seems to be an issue with blinking lights on these.

what is the model number?

suspected clutch throw out bearing
failing
pressing on the clutch pedal loads up the bearing and the noise stops but removing the foot from the peddle allows the the pressure plate fingers to spin a loose bearing race ans so makes the noise

If the noise you are hearing is a deep hard sounding knock or rapid metallic rattle that vanishes as soon as the oil pressure increases then you could have either excessive bearing clearance at a rod and/or main bearing or an oil filter that is allowing the oil in it to drain back into the crankcase which is delaying oil from reaching the bearings for the first couple of seconds which is essentially like starting up the engine with no oil in it as it takes a bit for the oil to refill the filter and galleys before it can reach the bearings. It could be a hydraulic lifter but they generally make more of a ticking or clacking type of noise and take a bit longer to go away...and may even come back at random times. To find the source of these kinds of noises I usually hook up a mechanical oil pressure test gauge, allow the vehicle to sit overnight, then start it up and see how long it takes to build up oil pressure. I then allow the engine to warm up fully [say 30 minutes of idling] and then recheck the oil pressure. If the noise stops as soon as the oil pressure rises then I'd try a genuine Mopar oil filter first to see if that fixes the problem. If the oil pressure drops off to less than 10 psi at a fully warmed up idle and doesn't get much over about 20 psi at 2000 rpm then you may have excessive rod/main bearing wear which would require some more serious work to correct. If the oil pressure stays at about 15 psi at an idle and rises to over 35 psi at 2000 rpm then the bearings are probably in decent shape yet. Hope this helps a bit and good luck!

The first thing I would suggest is a hard reset. Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.

If that doesn't work, leave it unplugged for about 5 minutes and try again.

Hi

If clean light is blinking then it may be an issue with heater circuit, door switch or wash pump, please reset the power to the dishwasher. After, 5 minutes check if you are still getting the same error. If yes, then it is a water heating fault. To resolve this error try pressing this reset sequence-- Heat Dry - Normal - Heat Dry - Normal or High Temp - Air Dry - High Temp - Air Dry or Hi Temp Scrub, energy saver dry, Hi Temp Scrub, energy saver dry. Now let the unit run for 2-3 minutes and then you press the Cancel/Drain button and allow it to completely drain and reset. If this doesn't work then it's an issue with the wash pump not pumping the water past the heater efficiently or due to lack of water to heat. Please make sure that heater is not open circuited and is heating the water efficiently. You'll have to check the heater using a multimeter; the meter should read between 3000 to 3300 ohms (Use multimeter on Rx1 ohm setting). If heater is fine then make sure water pressure is optimum and fill valve is working fine. Hope this helps... Please post back if you need more information.

II might need the actual model number. However, you can go to page 9 on this manual and check if the flashing options can fix the problem. I am assuming you have already tried to turn the power off and back on.

The ohter thing to try is the reset sequence. Within 6-7 secs press High Temp/ Heat Dry/ High Temp/ Heat Dry/ High Temp/ Heat Dry. All lights should light up, press Start button to exit.

Sounds like the water may not be turned on to the dish washer.
The arm spins with water pressure

something has gotten passed the screen and is jamming your pump impeller pull lower spray arm pull screen and see if you can find what is jamming the impeller and remove it drain pump is separate
