Hi, on the Bosch SHSM63W52N/01, the E19 error is most commonly caused by a failed heat exchanger outlet valve, also called the drain or solenoid valve.
When the solenoid inside that valve fails, it can no longer respond to the control board, which causes the dishwasher to throw the E19 error and stop operating.
I would start by checking that valve and its wiring first. If the valve checks out good, then move on to checking the detergent dispenser actuator and, lastly, the control board.
Can you help me out with a part number for the HEAT EXCHANGER OUTLET VALVE?
is that part of the CIRCULATION PUMP AND HEATER ASSEMBLY?
I am looking at schematics of the machine with part numbers to try and figure out which parts to test/check….thanks!
Hi, the heat exchanger outlet valve is not part of the circulation pump/heater assembly. They are two separate components.
The heat exchanger outlet valve (part #11033896) is located at the bottom of the large heat exchanger tank on the left side of the dishwasher. It controls water flowing from the heat exchanger back into the sump.
The circulation pump/heater assembly (part #12008381) is underneath the tub and is responsible for circulating and heating the wash water.
So if you’re replacing the heat exchanger outlet valve, you do not need to replace the circulation pump assembly with it.
