Уважаемые мастера! Помогите приблизиться к решению этой проблемы. Случилась эта ошибка после разборки для очистки кофейного блока. Единственное, на мой взгляд, что я сделал при сборке немного не так, как было, это более обильная смазка.
Ситуация кажется технически не сложной, если есть сообщение, есть и сигнал. Для заварного блока я не увидел приборов контроля (типа конечных выключателей или др.) позиционирования. Только на редукторе привода есть 3 проводочка. Я пока не знаю, что это, но скорее всего это источник сигнала об ошибке. Если это конечные выключатели или оптопара, то нужно найти соответствие их срабатывания и окончания движения поршня заварника вверх.  На завершении попытки движения заварника вверх возникает ошибка. Поэтому я, естественно, измеряю напряжение на конечниках привода, откручиваю его, вручную кручу шестерню редуктора и добиваюсь срабатывания, ставлю его обратно в зацепление, предварительно опускаю поршень на пару оборотов большой шестеренки типа для запаса хода и гарантированного срабатывания. Включаю, варю 2 или 3 чашки и снова та же ошибка! Теперь вопросы (возможно я пишу это для себя, так сказать для осмысления).
1. Как связано решение проблем с заеданием механизма и рекомендацией снять фаску с шестерни? Или Другие рекомендации по замене сита, колец, и особенно помола, и тд? Отвечаю для себя: c возможным контролем тока в цепи питания редуктора. Хорошо.
2. Если у меня варит несколько чашек, то управление питанием редуктора в порядке и ошибка связана с накоплением рассогласования в приводе мд положением ротора редуктора  и положения заварника, поэтому нужно его правильно поставить!
3. Но не может же замена редуктора с его установкой быть сложной процедурой для сервиса, вероятно это должно быть просто!
4. Концов для контроля от редуктора идет 3. Это либо 2 конечника, либо 1 активный датчик типа оптопары и тп. Если это 2 КВ, возможно я меряю не ту напругу. А маряю я мд средним и верхним на плате. у меня прыгает с  до 5v
5. заварник ходит очень плавно, ему ничего не мешает, при заваривании кофе или промывке под давлением пара поршень откатывается на 2-3 мм, естественно шестерни вращаются. Это нормально? Видимо да, тк в противном случае был бы самоблокирующий редуктор или стопор.
6. Я не понял, что за датчик расположен возле заварника. справа от него и слева от панели управления. Похож на геркон черненький, запаян в пластик, но вроде тяжеленький.
7. Не могу понять, как машина узнает, что ей не хватает зерен? Контроль тока мельницы? положение редуктора при прессовании в таблетку?
8. Мой план пока что такой: разобраться с редуктором, попробовать поискать сигнал на другой паре контактов, еще раз разобрать, посмотреть заварной блок.
Если кто-то может оказать методическую помощь или дать добрый совет, буду рад!  Вся надежда на мастеров!
