Had a search, but think my problem is different.
Dwh comes on for 15-20 second before going off again and then the cycle repeats. Water never gets really hot and there are no fault codes displayed.
Did have the stuck diverter problem recently (this is an Isar HE after all) but that has been fixed.
Dhw thermistor has been replaced too. What next?
