Main combi eco 25-error message help?

[Edtheball]

Hi folks,

Just wondered if anybody could help with my boiler problem?
It is displaying the error message E110,I've checked the installation manual and it says that the overheat thermostat has kicked in and to test the continuity between the terminals,I've done this and it is below the 1.5 ohm that the manual says is a guideline for the thermostat to be replaced and that if it is below this reading,the pcb needs replacing,would anybody recommend that I try replacing the thermostat first anyway? as this is by far the cheaper option and well.... times are hard? lol

Have you tried to reset the fault code or depowered for a while?

I would short the two contacts to test the pcb. However a non reg person should not be working on this.

Make sure the conector at the overheat stat is tight and well connected
