Wiggy Thank you for your detail answer, but I have a different problem, I have no display indication temperature gauge on display. 😅It is always active and the bars will move from left to right as the water temp increases.
If yours is not working i suggest you check the sensor wiring and or replace the temp sensor as that will be the likely culprit. It could also be that the thermostat is faulty and will need replacing.
In case you're not sure where the sensor is located i have attached a diagram to help.
