I have a bosch shx45 dishwasher that has been acting up.It makes loud noises and will not fill with water.If I fill it with a pitcher it works fine but still makes the loud noise periodically through-out the wash cycle.I have found a self test online but my machine is'nt running through it correctly.I hold the power scrub and reg wash button down,turn on the power switch,then release and press the power scrub and reg wash buttons again.The power scrub and auto wash buttons flash but thats it.How long does this test take?do I need to close the door(it has the hidden controls)?From what I've been reading I suspect the fill valve but would like to get a good test. Also I don't see a float switch in the tub Does anyone know where it is located.I did remove the lower front kick panel and removed the insulation.As far as I can tell there is no water in the flood pan if that was the flood pan I was checking. Thank you.

I recently had to change the door switch , I did not replace the front lower counterweight which came with the kit,. At one point during the process I did remove the rear wheel from the tub which holds the belt. I Also replaced the Upper springs and the Shocks. The old shocks were completely shot , and the tub would shake violently . Now the tub seems to be fairly stable but it rubs against the rear panel at times.
