Bosch dishwasher soap dispenser is not opening and rinse aid not dispensing as well. I did test the voltage going to the dispenser and I did register voltage about 25 minutes into the wash attaching to the 2 yellow wires. It appears that I need a new soap dispenser, but I would like confirmation. In checking the soad dispenser I noticed the rinse aid has not been dispensed. Are these a related issue solved by replacing the soad dispenser? I have been manually operating the soad dispenser for a couple of months. Before that it would work intermittently. Can you confirm the part number as AP2834000.
