US Boiler ES2 Error 32

Hans64

Found in the manual that Error 32 is a “Temperature sensor or interface failure (open or short connection, increased connection resistance, dual sensor mismatch) or control hardware failure“.
That’s quite a range of possibilities. Any ideas what this usually is? How do I please troubleshoot this?
I would appreciate any insights. The system is running, but doesn’t reach set point temperature.
Thank you

Did you do the next steps in the manual?

- Check sensor is securely attached to control P7 connector.
- Check sensor wire is not damaged.
- If secure and in good condition, replace sensor.
- If problem persists, replace control.
