I replaced the inlet hose as it was clogged up and cleaned out the red valve inlet. It works fine on quick wash but not on Normal wash 65deg. It shows up E18? I reset it and tried again and it works? The replacement inlet valve is out of stock, I’m not really sure that the valve is the problem. Any pointers?
