A list of Combi(E) fault-codes can be found here

(This was produced in 2011 and I’m not sure whether it exactly matches the codes displayed on a CP Plus control-panel.)

 

There are a few on-line references to the “E89H” fault-code, but (as far as I can see) nothing conclusive.

If you can’t clear the fault by trial-and-error, I suggest you contact the Truma(UK) technicians for advice

Looking at it further, if you have a CP+ control panel it seems more likely that you have a software problem and the controller needs a software update. As Derek has said many owners have had the same problem.
