Despite the magic it performs in the kitchen, a dishwasher is actually quite simple--it is essentially a watertight box that sprays dishes with hot water and soap, drains out the dirty water, and then dries the dishes.

Hot water is delivered through a supply hose that connects to a valve that controls the water's distribution to spinning spray arms.
A pump gets rid of the dirty water, and an electric heating element dries the dishes. All of this is operated by controls that may be very simple or quite complex.

check the following parts for their operational value. replace any failed part.


1. Air gap / Drain hoses
If there is an air gap (located in the sink, near the faucet), check to see if it is clogged. Unscrew the top cap and see if there is anything blocking inside. Note: If there is no air gap installed, the dishwasher might not drain properly.

If the drain hose is clogged, the dishwasher would not drain. If there is an air gap installed, it is very common that a hose going from the air gap into the garbage disposer is clogged. Remove and clean the hose. Make sure to reattach the hose before starting the dishwasher.

Note: If you recently had a garbage disposer installed, it is common to overlook removing the drain plug.

2. Broken belt
Some dishwasher models use a belt to drive the pump. Replace the belt if found broken.

Note: Sometimes the belt would just come off the pump. Even though it might not be broken, it is recommended that you replace the belt, because it is probably too stretched out.

3. Pump
Some models have two impellers inside the pump - one, wash impeller, takes care of the wash cycles, the other, drain impeller, drains the water out. If the drain impeller is broken (broken blades, shaft), the dishwasher would not drain. Replace any broken pump components.

4. Drain solenoid
Some models (for example most GE dishwashers) use a drain solenoid to drain water out. Sometimes the solenoid gets stuck, preventing the water from draining out. Try to free up the solenoid. If unsuccessful, you might have to replace the pump assembly.

5. Motor
If the motor is stuck, it is sometimes possible to free it up by manually spinning the motor.

Replace the motor if defective.

6. Timer
Replace if defective (note: uncommon problem).

I am looking for a wiring diagram for a Bosch Dishwasher SMU2046UC/14.


There should be a wiring diagram and other service information on a piece of paper behind the toe kick cover plate. That's where I found mine. Good luck.

Hi! My Bosch began by tripping the breaker during the cycle (several times if I could get it to reset) and now will not start at all. Even when the dishwasher is off I cannot reset the breaker unless I...


Hello

Welcome to Fixya.

Based on your post,"...Even when the dishwasher is off I cannot reset the breaker unless I kind of move the machine around a bit. Sometimes it pops the breaker just closing the door..."

These are the most common reason for these Bosch dishwashers not having power.


#1

I would start by first shutting off the breaker. Then removing the kick plate ( access panel at the bottom ) and checking the wiring at the junction box for the dishwasher 120vac supply line.

Remove the murret's and visually inspect the wire for "resistance burn" and strip the wires back and install new fastener's if necessary to repair.

i.e.

60f6a31.jpg

This is actually quite common to find a wire connector come loose due to improper fastening and once the unit is in use for a while the connections heat & cool, become loose from normal operating vibrations and burn up from all the added heat caused by "resistance".

#2


A wire severed inside the door panel, hence the breaker trips by just moving the door in an open/close motion.

Check thoroughly in this location...

The end result is tripping the breaker and no power to the controls.

Check it out and post back what you find. Thanks for visiting "fixya" and please take a moment to rate the solution/suggestion provided here for you.

Good luck.

Macmarkus :)

I have a bosch dishwasher model # I believe is SHX4AP05UC it keeps tripping my braker in the middle of washing wont complete a cycle any suggestions?


Adam, in order to help you, you must provide me with more info. What size breaker is tripping. What does the maufactor's manual reads about what size circuit it must be plugged into. If your house is a little old you probably have a 10 amp breaker that is tripping. If so than the manufaturer states theat it is recomamded to place it onto a 20 amp breaker. Only switch out the 10 map breaker to a 20 amp breaker if your the wire from the breaker is a 12 gauge wire.
Do not put a 20 amp breaker onto a 14 guage wire because it will most likely melt the insulation due to heat whichwill expose the bare copper wire which could lead to burning your house down.

Our Bosch dishwasher will not turn on. It appears to have stopped in mid-cycle - there is water below the dish rack. The circuit breaker on the main electric panel was not tripped. Thanks, Paul


check the dishwasher electrical box connection. remove kickplate. box is on r/h side. remove cover. you will probably find the wires and marettes burnt. simply repair the wires. this happens from time to time if the connection is not the best. hope that helped

Bosch snu 6806


Have you checked the breaker? Is the dishwasher on its own circuit or on shared circuit with the kitchen outlets? If shared with the kitchen, might one of your GFI's be tripped?

Make sure you visit the Bosch dishwasher recall website as this model is under the recall with a faulty controller which may cause a fire! Check your model under http://microsites.boschappliances.com/safetyrecall/dishwasher/
then call 800.856.9226 to setup a recall repair appointment. We just found out about this recall and was never notified by Bosch even though we registered our unit after we purchased it...talk about poor customer service! Hope this helps!
