I had it for two years and sought advice from several service technicians. Their suggestions ranged from electronic issues to problems with the pump. As an engineer, I couldn't accept such broad explanations. I decided to diagnose and fix the problem myself. In my case, the issue was due to poor ground (GND) connections for the NTC sensors. The GND connection was made through the pipes, and over time, the NTC sensors lost their GND due to copper corrosion. The permanent fix was to clean the copper pipe surface near the NTC sensors and connect two wires from there to the chassis GND connection. I hope this helps someone facing a similar issue.
Плата управления. В этом котле наличие (отсутствие воды в котле) определяется по датчикам температуры (датчика или реле давления в нем нет). Два датчика - на входе и на выходе с теплообменника, контроль циркуляции по разнице температур. Собственно датчики он проверил замером их сопротивлений. В цепи на плате датчиков на плате нашли неисправные элементы - заработало. Неисправность редкая, но случается именно на этих котлах. Из-за снижения характеристик элементов на плате она "видит" неверные показания и фиксирует как отсутствие воды в котле.

Как поднять давление на таком котле???
Как лечится это?
Скажите пожалуйста как понизить давление в этой марке комби? У меня оно 3 бара, кгмби постоянно отключается
С батерии выпустите воздух,а на котле закроите подачю воды...
Подскажите что пришлось перепаять в плате?, просто точно такая же ошибка у меня

как устронить эту не поладку
И какая причина
