Jackson high temp door style. Very hot water continues to spray from the rinse arms after the dishmachine has finished its cycle. Very hot water will spray from the rinse arms even when the dishmachine has been idle for a period of time. I noticed that one of the terminals on the rinse thermostat has an arc (burn) mark on it. Can the rinse thermostat be at fault?

You may have a leaking hot water electrovalve, replace it.

Common Problem

1. Confirm the wash water is hot
   1. Try heated wash(sani wash) if available
   2. Run hot water in sink to warm up before starting
   3. At least 120 degree Fahrenheit water temperature
      
2. Open door check wash arm position start washer for a minute
   1. Confirm wash arm has rotated
   2. Check for plugged spray tips at either end of wash arm.
   3. Use small tweezers to remove
   4. Check for rack and dishes interfering with arm rotation
3. Place cup in upper rack with opening up cycle washer.
   1. Confirm that cup quickly fills with water
   2. Not washing check water level in tub mim 1 1/2 inch
4. Discontinue use of rinse/dry liquid additive.
   1. Confirm rinse/dry additive not leaking from dispenser into tub
   2. Washer detergent contains sparkle additive and too much sparkle/rinses/dry additive will coat dishes
   3. Try alternative wash detergent that contains minimal rinse/dry additive and use without liquid rinse/dry additive.
5. It will take several wash cycles after the elimination of rinse/dry to purge the oily film from dishes and machine..
6. If success "joy" is achieved with no additives then cautiously add back wash detergent with additives. Additives are important to facilitate drying and protecting the glassware china from leaching. The leaching process permanently etches the surface of glassware leaving a cloudy appearance.

Check to see that both upper and lower arms are working. You can do this by suddenly opening the diswasher about 6 in and observing if the wand arm on top is revolving. This is done by water from the lower arm being pumped up through a tube mounted in the lower basket that centers over the lower arm and upper arm. Check that the tube is clear. check that water from the lower arm center is being pumped. Check that the hole is clear. if you have hard water, then sometimes the holes get clogged up and the arm will not rotate.(just like a lawn sprinkler) The upper arm rotating is what washes the detergent out of the soap dispenser. To aid in cleaning the spray holes, pour some white vinegar in the bottom of the machine about two cups, and turn the machine on high temp wash. Do not let the mixture drain out untill you have cycled it about five times. When the wash cycle has about finished stop and restart. The acid in the vinegar will help disolve the calcium and hardened soap. After the finish rinse cycle, you can put a little lemon juice in the machine and let it was through, that way the vinegry smell will disapate.

you may need to clean out your hot water heater depending on how old it is and yes 80 gal should be more than big enough adj. thermostat to the next level

Heating element may fail. This will lead to the machine stopping part way through its cycle

Pumps. There are 2 pumps in most dishwashers. The drain pump,( which describes itself -it pumps the water out of the machine.)
The recirculating pump which forces the water at high pressure through the spray nozzles and arms. (This is how the cleaning action is performed)
These pump may either leak, or burn out. Either way, the only solution is replacement.

open the door when in cycle and check both spray arms are rotating. you will get a bit of water out but not a lot. if arms not rotating, then this is caused usually by rubbish in the spray arm jets so clean them. also check water is being heated

Most DW today take a minimum of 90 minutes. Run the hot water from the sink until it gets hot, then start the DW, this will shorted the first wash cycle. It is not uncommon for the DW to run 2hrs or more based upon the water temperature entering the DW and the soil level of the items in the DW.

Mimmi, If the water isn't reaching temp this will happen. It sounds like a heating issue.
Guest,
The spray arm being blocked will not cause this. Again your machine isn't heating the water to temp.

If the reset procedure (those buttons you pressed) didn't work, it's because the machine is still reading a fault. It could be a few things... water temperature too low (indicating a bad heating element), partial blockage of the drainage hose, or something preventing the spray arm from spinning. If letting it sit for a while allows it to start again, I suggest you do that. It will stop again and the lights will start blinking. When it does, open it up immediately and see how much standing water there is. If there is a lot, look for a blockage in the drainage hose. That's the most likely, I think, because it makes sense that it would work again once the water slowly drained. If there isn't much water, then see if the water that is there is hot. If it's not, then it's the heating element. Checking for movement of the sprayer arm is a bit trickier, as it won't be moving while the thing is open. Though, if the first two are not the problem, there's a good chance that is. Or, of course, it could be a malfunctioning control panel giving false errors. There's really no way to test for that, unfortunately - but I don't think it's acting like that is the problem.
