Having problems with your Bosch SHU3306UC Built-in Dishwasher ?

Two problems: the water pressure in the arms is low. If you pop the door, arms are not spinning as it should. Each time you start and stop, the arms move a tiny bit. Have cleaned the filters and the spray arms completely. Also, detergent door no longer pops open.

Hello,

Welcome to fixya.

\015\012
\015\012I just came across your post and I'm surprised by the direction it has taken, in fact the "flow switch" as you showed in your picture has nothing to do with water intake or level, it is a component which tells the heater the unit has water and thus activates the heater once the ciculation pump comes on and senses water "flow".

\015\012I have a complete Bosch dishwasher service manual I can send you if you want to provide an email address to which I can attach it to.
\015\012
\015\012I'd suspect either your water valve is collapsing ( not likely though, they usually fail in the open position or closed...not in between ) hence not allowing enough water or the water level switch & diaphragm is faulty/stuck. It is located on the left side when facing the front.

First question is your unit under warranty at all i have to ask this because i do not want anyone to void there warranty now as to the first problem with the water pressure have u checked the water valve? part number 19 in this diagram http://www.searspartsdirect.com/partsdirect/part-model/Bosch-Parts/Dishwasher-Parts/Model-SHU3306UC12/1794/0130000/50020668/00005?blt=06&prst=&shdMod= you may not have enough water going through the valve or maybe only one side of the valve is working these are things you would need to check if the pressure coming through the valve is low this would also cause the arms not to turn freely as to the detergent door this you would simply have to replace as you can see they make very few parts for the detergent door in this next diagram http://www.searspartsdirect.com/partsdirect/part-model/Bosch-Parts/Dishwasher-Parts/Model-SHU3306UC12/1794/0130000/50020668/00002?blt=06&prst=&shdMod= there is a little spring that might have lost its tension but usually we just replace the whole detergent door assembly to assure customers dont have any problem any more with unit whereas if you replace one small piece and two weeks later another small piece goes your going back for same thing if you have any further questions message me back if water pressure is fine going through the valve message me back with this information as well and please remember when our chat has fully concluded to rank how this opinion has helped it allows me to help others in the future with similar situations Thanks Rick

Mod #: MDB6600AWB Ser #: 16505148CG No water comes out of spray arms, checked and cleaned filter-OK. Wash impeller is cracked where it slides onto the hexagon rod but it you take the filter flow plate off and put the impeller back on, when you put the unit on rinse only and quickly open the door you can see it is still turning and moving the water. The unit still fills and drains. it just does not have enough force with the impeller to force the water into the spray arms.

Bosch Exxcel model number SGS46E12GB had the check water light on a week ago, checked supply and cleaned filters, all good. light still on, got upset and slammed the door, light off. since then the unit will either wash stuff, or not. didn't seem the arms were spraying very well when I opened the door, so I bypassed the door switch tonight and put it through a pre rinse cycle.

My dishwasher is not working properly, i have cleaned all the filters and spray arms, but still have food partials all over dishes. I did use a knife to hold down door latch so i could see what was happening when the dishwasher is working. Water does come out of the spray arms but they don't move and the dishwasher is empty, also now the latch won't catch since i used the knife.

My dishwasher spray arms were clogged with calcium buildup so I cleaned one and replaced the other. I also removed the fixed disc-shaped device underneath the lower spray arm and found the particle filter was clogged- so I cleaned it out. The dishwasher ran fine for a few times but then the filter clogged again, and again, and again. Now I need to make a routine of disassembling the parts to get at the filter every week because the filter no longer clears itself during the wash and/or emptying c
