How can I check, if the magnet valve is blocked?

Scroll down in the display menu until you reach the temperature display. Observe, if after crossing the switching threshold, the temperature doesn’t change, that the solenoid valve is blocked (when the 2nd thresholds are reached the message “over- or undertemperature” will be displayed).

NOTE: The error message “Ths too low (Ths = Temperature Heatsink)” might be an indication for a contaminated valve.
