Truma Error E508 H

Hi,

Have replaced leisure battery with new & I am now getting  error E508 H when trying to use heating  Tried turning power on and off error came back up believe I need to reset the boiler but no access i  have a 2016 Peugeot Auto Sleeper as the control panel is facing  to the outside of the vehicle so I cannot see the reset switch, any ideas would be appreciated????

Try going back to truma panel and make sure heating and water are switched off. Then switch on power code should disappear

I had a similar problem and spoke to Truma about the re-set.  You can do it with the boiler in place but you need to be a bit of a magician with a mirror etc.  I was told by a Truma technician last week that you can re-set it off the control panel, but going back to the Initialisation screen.  That is going to be a much easier route, i suggest, than trying to re-set via the boiler.  Good luck !
