Ariston Eurocombi boiler error code 103

Hi Folks,

I have installed Ariston Eurocombi boiler four years ago. From last few days, I am noticing that something is wrong with my boiler as it shows an error code 103 on daily basis. Please share your views along with solutions if someone has faced this issue previously. I am worried please help.

Thanks a lot

James

Hi James,

An error code 103 on Ariston Eurocombi boiler means insufficient circulation. The two main reasons behind this error code are:

  • Heating system is chocked

 

Generally, blockages in the heating system originate from heating mud. It is a rust and grime buildup in the boiler, radiator, and pipes. It will not let water to flow properly & therefore an error code 103 is being shown.

  • Issues in the heating pump

 

When the boiler’s heating pump does not circulate properly, hot water and radiator will not get up to the required temperate.

It is advisable to call a boiler professional to solve this issue in a better way.
