My Compact Bosch machine ( second owner) wont go throught its cycles yet it does do all functions when set on the selector. I was told too mach soap can make it stay in wash mode until it hits 1 minute. Is there a sensor I can clean?? It did go to Rinse /Spin on its own but only in Delicates cycle. I have run a few washes without clothes or soap to no avail.
