Truma error code 623

[ian224]

Is there a specific order to follow when turning everything on so that error codes don’t appear?
What do I do if a code appears?

No set order. e623 is cleared by resetting the heater unit. Mine was caused by selecting water heating with a dry tank.

Many thanks. When you say the heater unit, is that the boiler itself? I’m new to this so your reply is much appreciated!

Yes the boiler is the heater. Truma web site is helpful if you do not have a manual.

What age of boiler is it?

If the boiler is fairly modern you can run the heater with the hot water system drained down. This is so if you want to use the van in the winter you don’t have to drain the boiler down when you finish

If all else fails and you can't clear a fault code try a hard reset. Worked for me. See link below
