Hey Ricardo111, you have helped me a lot, I have posted this and hope you will get back to me: Hey, I have a Vaillant Thermoblock turboTEC II that my plummer has given up on. He has exchanged almost everything. It is still unable to restart and goes on F.24 or (if I ask for hot water and centralheating) it will go on forever (two bad things for a heater - never start and never stop - I am looking for the opposite).
Then I found Ricardo111's answer: THE F.24 FAULT CODE IS GENERATED WHEN THE RISE IN TEPERATURE BETWEEN THE TWO `NTC` SENSORS IS TOO FAST A GRADIENT (USUALLY). THE PCB TRANSLATES THIS INFORMATION AS `NO WATER IN BOILER`, AND LOCKS IT OUT WITH F.24, CAUSING YOU TO PRESS RESET. IT MAY THEN WORK FOR SOME TIME. UNSCREW THE NTC`S AND CHECK BEHIND THEM FOR MOISTURE-THIS CAN CAUSE F.24, OR LOOSE NTC`S NOT SCREWED FULLY HOME INTO THE SOCKET.
Dear Ricardo111 (or anyone else) - my plummer says this is an uption, and he knows what NTC is. But can I do this myself and remove moist?
