I Can transfer fault to either draw by changing the controller,
this gives u3 as well, because its not able to empty in the time available. if you cut of the water supply b4 fault code comes up its works fine
Does anyone have data on how to set it for low or high pressure, water suppply, I read elsewhere this could be the cause.
and water temp as well, this takes longer that it should to heat up, about 10 mins longer than the other draw, although it does heat up and run ok.
apparently its some special button combination to enter adjustment mode ???, all these problems are on one controller only, so i guess i have eliminated everything else by a change around
