My machine has an intermittent fault. Summary (apologies for length)
- It's an inherited dishwasher from previous owners (who say they never had problems with it) so don't know the full history.
- worked fine for a couple of weeks on 65 degrees setting, cleaning well and then just ran on one morning (had been running all night) and seemed to be stuck on the rinse cycle with lots of water in the dishwasher when interupted it
- After a few attempts to reset and end cycle it finally did, but on trying a cycle again I just had the same issue.
- Post here indicated about Anti flood device, so I pulled out the dishwasher, tipped it (more than 45 degrees from vertical) and no water came out at all
- Put in back in place and it worked around six times on the 50 degrees wash (initial cycle taking a normal amount of time, but the last completed cycles were taking around 4 hours) before it did the running on and on
- This time it seems it consistently gets to a point in the cycle when it is trying to drain and there is a draining sound made regularly from the sink waster, then 20 second hum, then more drain noise etc. The dishes are clean of food etc and seem quite washed, but (it has definitely got through the heating the water up stage) but there was a slight film of something left on the dishes and it hadn’t seemed to get to the steam stage. There is no or a very small amount of water left at the bottom of the machine and some of the glasses often have water still in them, the dishes don’t though. This time, you if you press the reset buttons to end the cycle it ends very promptly
- pulled it out again, tipped it as before, no water came out. Put it back in place, dishwasher also completed another couple of cycles at 65 degree washes, but then the same problem of it running on and on several days ago and getting stuck at the gurgling draining point. If you press the reset buttons to end the cycle it ends very promptly. It could complete a prerinse cycle. Completed a 35 degree cycle yesterday.
I'm fairly confident the heating element side is working as when it does work, it's all coming out steamy hot. There could be an extremely minor leak somewhere (which dreis out in between some cycles) which could well be an effort to find and so I'm tempted to call someone in to just replace most relevant seals - my worry is that some other major part is wrong which is expensive and I should just get a new dishwasher!
I know test cycles tend to test the heating side, water fill and empty side and the NTC sensor, so would like to be able to run this to eliminated heating and NTC if possible (or does the fact that it works sometimes already eliminate these?)
Soz for long post!
