Re: bosch dishwasher e19
If you are talking about the wax solenoid that opens up to drain the right side tank then just plug on one nicked from a dispenser unit and the fault should go away. The “liquor tank” as it is called by Bosch only drains at the beginning of the cycle and then refills at the end. I found the hose that joined the tank to the nozzle on the diverter valve was blocked and that caused the tank not to fill, didn’t error code though.
Hope that helps!
