How to fix a 10e fault code
For the Navien boiler error code 10e, you’re probably looking at an issue related to the air pressure. When the air pressure is too high, then the system shuts down to prevent any further damage being done to your boiler. There are several reasons why this might happen, including:
a damaged air pressure hose
clogged condensed water hose
faulty air pressure sensor
So, this is one of those issues that does need an engineer to come out. They’ll be able to work out precisely what might be causing the problem and suggest ways of getting it fixed.How to fix an 02e error code
The most common cause of this problem is low pressure in our heating system. Have a check of your Navien NCB combi boiler manual to determine what pressure your boiler should be to see if this might be causing the issue.
