This machine brings up E18 – fill problems. However, it will only do it on the second fill. If the machine is run on the Quick Wash, it will drain, fill, circulate and heat (and operate the dispenser), then drain. During the second fill, it wll do so for 30 seconds and then cut the valve off wth E18 showing. I am assuming that this is a logic error and the PCB is faulty.
