Daikin Altherma Problems
I have a Daikin Altherma air source heat pump installed and has been running fine for the past 2 years. A couple of weeks ago it gave an error - 7h
The fault code states - 7H indoor unit LT: Flow switch activated water flow rate too low or blocked inlet strainer
I have cleaned the strainer in the pressure reducing valve this evening and will wait and see if it has cured the problem - it was slightly filled with rubbish.
Here is my question: when the error 7h was displaying and I pressed the "Test" button once on the control panel, this was displayed: -
160
7 2-
and if pressed again, this is displayed: -
160
7 J6
Are these further clues as to what the problem could be?
J6 Error code is Outdoor Unit LT: Malfunction of thermistor for outdoor heat exchanger.
The model number for my unit is: EKHBH016BA6V3 and EKHWSU300B3V3
Thanks,
Simon
