Could you explain why the bottom arm spray is not spinning but the top one is working fine

SOURCE: dishwasher does not clean properly

sewnice, you might have to dig a little deeper to correct the problem. As long as you can spin the spray arm with your hand and it's not split it should be ok. Your chopper screen might be plugged. You will have to remove the lower spray arm and filter cover. These are torq screws. The accumulator assy. turns to the right to unlock and will lift off. It will take some pressue to snap it off the rear fill tube. Now you will be looking down at the cover that protects the chopper and screen. There is one torq screw holding it down. Remove the screw and lift it off. See if the screen is clogged. If it is, it will prevent the pump from sending water to the upper spray arm in force. Catriver..post back

SOURCE: I replaced the spray arm seal, but the arm still wont spin.

arms should turn freely. spray arms are only rotated by water spraying out from angled jets at end. check for blockage in spray arms - sweet corn and rice are the worst offenders. take spray arms off and run water in centre hole and see it runs out of all the jets freely

decrete, you want to get down to the chopper and screen. If the screen is plugged up with gunk there won't be enough pressure to reach the top spray arms. Check out the posted pics. Remove the lower spray arm. Rotate the rear feed arm to the right until it unsnaps from the tube going up the back. See the 4 torq screws holding the filter on. Remove them. Lift the filter up. Now you will see the chopper inlet cover. 1 torq screw holding it in. Lift it up and there's the chopper and screen. Catriver..post back

Now that's out of my system I can try to help troubleshoot your problem.

Bosch dishwashers use a water system called FLOW CONTROL... which utilizes a valving system to control which arm gets water during the cycles.

Most washers see water at both arms all the time. Yours is controled with a PLC and uses information gathered from onboard sensors to tell the valves to open or close.

Your Lower sprayarm valve is faulty, or the controller board is bad.

Since we do not know your mechanical/troubleshooting skillset - all we can do is offer advice and try and help you if you feel this is a problem you would rather attempt to tackle yourself.

I have searched BOSCH website and could not find your model washer in their documentation. Please double check that it is SHV55M03GB/40 that you posted.

Thanks akubra_lands, it worked for me too on model DW28W. I thought I should elaborate on your answer for anyone else who comes across this while researching the same problem.
The repair is ridiculously simple (takes about 10min) and the only tools needed are 1 philips/posidrive screwdriver and 1 flat blade screwdriver. Assuming you've unplugged it from mains power:

1. Tip the dishwasher on its right hand side (looking from the front).
2. Remove 4 screws from the metal base - 2 front and 2 rear (the rear ones have anti-rattle washers on them).
3. Pull the base away, taking care of the pair of wires leading to the flood indicator float switch which is still attached to the base.
4. Remove all 4 screws which fasten the solenoid valve to the pipe which leads from the pump upwards to the center of the tank (which feeds the lower spray arm).
5. Pull the solenoid/valve body off the pipe and you will see it has a whitish plastic flap with a hinge at the top end.
6. Use the flat blade screwdriver to gently prize open one side of the flap hinge and twist the flap until it is completely free of the valve body. Put the flap to one side.
7. Replace the valve body, without the flap, and secure all 4 screws.
8. Reassemble the dishwasher. Done
