My bosch dishwasher takes 4-5 hours to finish the sycle, what is the problem

First check out your model to see if it has a built in garbage disposal, if so, make sure it is not mucked up.
Run hot water down your sink drain while running the sinks garbage disposal. Pour baking soda down your sink garbage disposal followed by white vinegar. Let it sit and foam. Run hot water down sink disposer while running. When finished:
Run empty dishwasher with no soap, let dishwasher fill with hot water to wash and then pour 1 cup of white vinegar into the bottom and resume wash. Make sure you take it through the dry cycle. When finished, open dishwasher and let it air for a couple of hours, longer if you live in humid area. Hope these steps do the trick.

use 'Finish Quantum' soap with a solid rinse aid.

in my experiance as a service tech dishwashing powder is supposted to b non foaming. try running dishwasher with no dishes or powder in it for a couple of washes. that will get rid of excess soap. unit has to much soap in it and the pump will not pump out soap suds. please reply 4 more help.

uou must replace the module control. some of those control are covered under the recall at bosch.call bosch or go to thermador .com they are the same company. hope this helps.

Well not going into the dry cycle could be a timing issue or a EOC (control panel) issue and will need to be addressed. But most dishwashers these days have a active run time during normal cycle of 110 to 120 mins, and thats not including the heated dry feature. I would let the unit run and see if it will finish on its own, and if I say it pushes two and half hours then something is wrong. A tech would most likely have to look at it, also a power reset could help but thats like a 30% chance.

No it is not. But, are you setting it on the shortest cycle? Maybe you got it on the longest, but wow 4 hrs? That doesn't sound like German engineering at its best.

If you have a Bosch shu4300...check this site.

My issue was a heater fault and fixed the problem by resoldering a bad joint. Works fine once this was fixed.
