does anyone have a tech manual for this older model? tested valve 1000ohms and tested drain motor 16 ohms, i think the timer is not working as water will not load or drain.

Looks like the problem is a bad water valve - 1000 Ohms is too much. Normally it suppose to be about 20 Ohms to 50 Ohms.

- The part number for the water valve is AP2802210

Here are the break down diagrams for the Bosch dishwasher Model SMU3032 UC/14 (FD 7507-7902)

Gene.
P.S.It is very hard to find any technical documentation for a such old model.

thanks Gene,
the values for water valves are normally 1000ohms where do you get your value from. there is no voltage going across the water valve either?

Sorry, my mistake - looked at wrong place. It suppose to be about 1 KOhms.

Did you check the float (on the left side of the dishwasher)?

You probably can test the timer, using the tech wiring diagram.

Gene.
P.S. You also can use the troubleshooting, attached to this reply.
