Non scientific but practical work around, from experience of same error code.
De-power the machine (not just turn it off) for about five mins, to loose any residual short term memory.
Power it back up, it will either still be in mid cycle, stop it, let it pump out and go to END; and/or, turn it off as per normal.
Power it off again for a couple of mins.
Re start with new program and if your machine behaves like ours, it will run through to the end without any problem.
