My bosch dishwasher model shu4022uc/u06 dlx series gets stuck between rinse and drying cycle. if you turn dail a hair it will finsh complete cycle.

There are several places on-line where you can find this parts. Depending on where you are. For example you can look up www.dlpartsco.com

The Self-Help section in your manual states you can adjust the volume or deactivate the beeping signal. Instructions on how to do so are supposed to be in the "cycle completion signal" section of the manual which it appears the tech writers forgot to include in the published version of the manual. I have not worked with this particular model so your best option now is to call their customer service number and talk to someone that knows how to turn it off. FYI, their customer service phone number is 800-944-2904.

Wash Cycle Options

Delay Start (model dependent):

This option allows you to delay the start time of your dishwasher up

to 19 hours.

Sanitize:

The Sanitize feature is available only in the Heavy, Auto, Normal and Half Load cycles. Press the

"Sanitize Option" button to activate the Sanitation features during these cycles. The technical sanitation

measures may also improve the drying results. The sanitize LED or The "Water Pipe" symbol will light when sanitation

requirements are met.

Note: The dishwasher automatically defaults to Auto Wash when turned off and back on. If you used the sanitize option
in your last cycle, the dishwasher will default to Auto Wash with the Sanitize option selected when you turn it on.

To achieve proper drying, always use a liquid rinse aid, even if your detergent contains a rinse aid or

drying additive.

Note: The dishwasher indicates low rinse aid by turning on the Refill Rinse Aid indicator LED (for units without

a display) or The "Spray Looking" symbol (for units with a display).

If this light is on, you need to refill the rinse aid dispenser

I got the idea that the "squiggly arrow" has something to do with the sanitize feature also. If you post your model number "on the inside right hand side of your dishwasher door" I'll go get your manual and post the link here. Hope this helps so far! :)

change the control module. im a old bosch tech. send me a 4thumbs post if this was helpful

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.

If the cycle doesn't complete, check these:

Water-heating cycle
Timer
Water-heating cycle Many dishwashers heat the wash and/or rinse water to a higher temperature, as the cycle calls for it. In these cycles, the dishwasher pauses after it has filled with water, waiting for the water to reach the pre-set temperature. What happens next, depends, as follows:

• On some units, the pause is timed and the unit continues after the allotted time.
  
  
• On others, the cycle can't continue until the water reaches the higher temperature. If you have this type of dishwasher and the water isn't being heated (say, because of a problem with the heating element or thermostat), after the unit stops at the heating cycle, it never continues. When you repair the heating-system problem, the "cycle problem" is fixed too.
  
  

Timer Timers don't often fail. But if every other part of the dishwasher seems to be working properly and the timer knob seems to be stuck in one place--doing one function continuously--the timer may be at fault. Dishwasher timers can't be repaired. If yours is defective, replace it.

SOUNDS TO ME YOUR CONTROL MODULE IS NOT WORKING CORRECTLY

It could be a sensor or timer solenoid in the dishwasher maybe broken and needs replacing.

remove the kick plate at bottom of dishwasher, at the left leg there will be a wiring diagram. remove console and test element from there. diagram will show which wires to test

Make sure that the drain hose is connected as per manufacturer instructions, and that there isn't a direct run down from the sink u-bend to the machine. The rinse agent effects dishes dry but has nothing with the water remaining in the machine. Good luck!
