Time to call an authorised repair agent.

Here is a link to the 556FTR from Australia.
They are all pretty much the same. The US site has similar info. Just google Rinnai. Open the site, go to resources tab and click downloads. The manuals are easy to locate.

Hi.

Error code 14 is Overheating error.

The error can be caused by the high limit sensing overheating and cutting off. In that case the thermal fuse may not blow. The high limit can be reset tripping circuit breaker and allowing the unit to cool down with power off.

If that does not work , then the thermo fuse has blown

In fact tis unit has a thermo fuse. (refer to manual).The thermal fuse can be tested reading continuity. If thermal fuse has blown, then replace the the thermo fuse. If the thermo fuse blows again, then there is a condition causing overheating.

Here Full service manual.


Unless you are a trained technician call Rinnai support ringing the number in the manual. Some of testing and repair operations described are not suitable for the home user.

Regards.

Ginko.

all energysavers have the same controls so any manual will do. www.rinnai.co.nz navigate to Tradesmart, space heating, energysavers.

Red filter light means the filter is blocked.
its located directly on the back of the heater and the wall spacer, from the control panel, its about 4 inches back.
Pull it up, clean reinstall
