Hello & thankyou for your tutorial, I have a Saeco Intelia HD8752 about 11 years old with the following issue: If the unit hasn’t been used for a few hours or the power plug is unplugged and plugged back in again, upon power-up, the automatic rinse cycle starts as it should: You can hear the pump groaning, sounds like it is blocked. This automatic start up rinse is either very slow with little intermittent hot drips taking many minutes for the cycle to complete - which then leads to normal use. OR No automatic start up rinse drips and therefore the process fails entering into ‘prime mode’ which also fails & leads to an unusable ‘maintenance spanner symbol’ code 5. The only way to bypass this is to unplug and re-plug in the power plug, power-up the unit, then as it tries to perform the automatic rinse cycle, manually press the STOP option to bypass the automatic rinse and then the machine can be used as normal & makes great coffee. Note: The above symptom’s got worse after I performed a de-scale cycle, which failed at the end with of the final rinse / prime - but fully worked up until that final point. Maybe there is lime scale lodged in one of the following places: 1. Boiler 2. Solenoid valve 3. Steam & water regulator Note: This is strange because it is 100% possible to run the manual rinse cycle as per the instructions: Press the ‘pre-ground’ coffee button (with no coffee in it), then press the coffee / memo button and it does a big hot rinse no problems at all. Also, after use, when the unit is powered off, it performs a small rinse cycle with continuous hot running water coming out the dispenser, but only for a very short time. I have totally re-built the brewing unit per various RUclips demonstrations with new stainless steel plunger screen + plunger o-ring, disassembled & blasted out all the tiny holes in the plastic plunger, made sure all the elbows and holes are clear and clean, installed the valve spring and glass ball correctly, greased all the o-rings, sliders and pivots. I have also fully taken apart the dispenser locater under the LCD display, disconnected the tube that connects to the brew unit, blasted water + compressed air through it so that it is 100% clear. Fully internally cleaned out the dispenser unit. I have calibrated the coffee grinding unit. The other issue I have is that that GREEN does not work on the LCD display - however I can still faintly see the LCD instructions - enough to get by. I haven’t run the LCD display diagnostics because that is too difficult to see / follow. But it seem like the pump + grinder & heater all work. I have disconnected & reconnected the LCD & checked the other wires, but can’t see any damage. Years ago the green would flicker on every now and then, but dead these days..
Спасибо, всё гениальное - просто! Класс! Лайк и подписка. Поделитесь пожалуйста какие диоды ставили? Похоже ставили по две штуки на цвет? Благодарю за ответ.
@@ilagen75 Спасибо за быстрый ответ. Правильно ли я рассмотрел, что диоды с бесцветными линзами, имеют выводы и диаметр их около 5 мм? Извините мои познания в электронике близки к нулю.
А, Вы молодец! Спасибо за инструкцию. Поможете многим людям!

Привіт. Вирішили проблему?
Попробуйте замінити насос.
Зелене світло на дисплеї не горить - потрібно замінити дисплей або перепаяти світлодіоди

Приветствую Александр!
Модель светодиодов не знаю, просто пришёл в магазин радиодеталей и попросил самые яркие зелёные и красные
@@ilagen75 Спасибо за быстрый ответ. Правильно ли я рассмотрел, что диоды с бесцветными линзами, имеют выводы и диаметр их около 5 мм? Извините мои познания в электронике близки к нулю.
Да, бесцветные линзы. Диаметр точно не помню, скорее всего 4-5мм, выводы были довольно длинные, откусывал.
Здравствуйте. Не очень видно, сколько светодиодов используете.
Здравствуйте
С каждой стороны по два светодиода -красный и зелёный
Спасибо! буду пробовать
А почему шепотом-то, секретно что ли? Громкость на полную вывернул, всё равно не внятно...
Добрый день. Не могли бы Вы оставить почту или вайбер, как раз столкнулся с такой проблемой, не хочу засорять коментарии своими вопросами. Спасибо.
Сделал всё как описано, но светодиоды не горят.
Полярность пробовали менять?
для чего резисторы ?
Резисторы нужны для работы светодиодов-они задают рабочий ток(10-20мА). Без резисторов светодиоды сгорят.
