Thank you very much i will check and report back to you. Peter.

is there a way to make a change to board to start boiler manually so it stops at right temperature by using temp sensor and bypassing microprocessor? thank you.

in test mode temperature shows up as >97c. but boiler cold. when i energize boiler in test mode it heats up. i checked board for shorts and everything seems ok. when i power board on connector goes from 1.92k to -4.41 on display. when i switch multimeter leads goes to infinite. what part on...

thank you i will check.

thank you very much

hallo, Problem mit Saeco Vienna Maschine. veränderten Temperatursensor und mittleren Licht blinkt nicht zu zeigen, Kessel heizt, geht aber auf soliden sofort. prüft Widerstand der Temperatursensor beim Start = 1.92 k. im Testmodus Kessel heizt sich auf. wenn ich starten Maschine geht es von...

hello, problem with saeco vienna machine. changed temp sensor and middle light does not flash to show boiler heating up, but goes on solid right away. checked resistance of temp sensor at startup = 1.92 k. in test mode boiler heats up. when i start machine it goes from 1.92k to infinite...
