Hello, I am the owner of the Galmet Neptun Kombi DHW exchanger with electronic control.
I can't heat the water for some time, the exchanger starts up, then turns off after a second and so non-stop, sometimes after a few resets it will work and heat the water, but it happens sporadically. After pressing + and - on the temperature controller, it shows error E3, i.e. according to the instructions
Unfortunately, the attempt to "Reset the thermal switch" has no effect.
I also recorded a short video of how it looks in practice
I unscrewed the electronic controller from the exchanger. What does the thermal switch look like in this model, where to look for it? Or maybe you know a different solution to the problem?

Quote:5.2. Thermal switch
The thermal switch is an independent protection with a separate temperature sensor which, in the event of a thermostat failure and heating the water to 85 ° C (+- 3 ° C), cuts the power to the heater at both poles. after the thermal switch is triggered, the error code E3 flashes on the display and all the thermostat functions are inactive.
5.3. Resetting the thermal switch
The thermal switch is non-triple, it means that after activation (turning off the heater) it requires user intervention to restore it to the previous state. After the thermal switch has tripped, disconnect the device from the mains for at least 5 seconds and then reconnect the power supply. if the temperature has dropped below 85 ° C, the thermostat will return to normal operation
