Важное примечание для владельцев котлов Viessmann (Висман): обслуживание данной техники рекомендуется доверить профессионалам, которые специализируются на техническом обслуживании этого немецкого бренда. Именно они обладают достаточными знаниями и практическими навыками для устранения ошибок viessmann. Если понадобится провести закупку новых деталей, приобретайте только официальные запчасти бренда-производителя, поскольку он будет гарантировать качество и надёжность деталей котлов. Если владелец котла выполнит все эти условия, он может рассчитывать на более длительную, безопасную и комфортную эксплуатацию аппарата. Нельзя игнорировать появление кодов ошибок viessmann на дисплее котла — нужно в кратчайшие сроки заняться осмотром, диагностикой и выявлением технических проблем или механический повреждений деталей котла. Ремонт оборудования не должен откладываться надолго, иначе приведёт к полному выходу котла из строя.
Онлайн диагностика ошибок котлов отопления
На этой странице мы собрали наиболее часто встречающиеся ошибки, которые возникают при эксплуатации отопительных котлов.
База переодически пополняется. Если Вы не нашли необходимую Вам ошибку, свяжитесь с нашими специалистами.
Мы обязательно Вам поможем.
Наш сервис подбора ошибок котлов онлайн — единственный ресурс с полной базой кодов неисправностей.
Мы потратили много времени, чтобы собрать коды неисправностей всех производителей в одну базу, систематизировать и настроить работу ресурса.
Зато теперь любой владелец или сервис-инженер может быстро найти нужный код и получить развернутый комментарий по конкретной ситуации.

Зачем нужны все ошибки котлов в одном месте
Мы собрали вместе ошибки котлов BAXI, Navien, Ariston, Bosch, Protherm и других производителей, ошибки двухконтурных котлов и одноконтурных моделей, коды неисправностей редких и давно снятых с производства аппаратов.
Изначально база собиралась для помощи в ремонте, но как оказалось запрос «ошибки газовых котлов» — популярен в поисковых системах не только у сервис-инженеров, но и среди пользователей.
Через онлайн подбор можно быстрее найти ошибку котла
Первая причина высокого спроса на ошибки котлов Vaillant, Ariston, Electrolux, AEG — через интернет гораздо быстрее найти информацию, чем в инструкции по эксплуатации.
Даже если документация к котлу лежит где-то рядом — нужно найти страницу, сверить код неисправности с таблицей.
Кроме того, в некоторых мануалах значения и рекомендации указаны отдельно.
Например, коды неисправностей котлов Fondital и некоторых моделей De Dietrich аккуратно приведены в таблице, а пояснения приходится искать по всей инструкции.
Иногда производители приводят длинные списки, в которых трудно найти нужный код.
Так выглядят некоторые инструкции с ошибками котлов BAXI, Buderus, Viessmann.
При диагностике такое подробное разделение неисправностей помогает, но приходится искать нужный код в длинном списке.
У нас неисправности приведены в алфавитном порядке, даже если в инструкции расставлены иначе.
Сервис ошибок котлов помогает, когда инструкции нет под рукой
Вторая ситуация, когда проще искать значения кодов онлайн — если документации нет, она устарела, трудно читается.
Документы могут потеряться при покупке котла с рук или если дом достался с готовой системой отопления.
В этом случае без поиска в сети не обойтись.
При сборе базы мы сталкивались с ситуациями, когда инструкций на русском языке или в нормальном виде нет и в интернете.
Тогда мы переводили и печатали вручную с бумажных носителей и нечитаемых pdf файлов — так пришлось собирать некоторые ошибки котлов Ferroli, Airfel, Rinnai.
Есть бренды, которые отказались от выпуска котельного оборудования.
Найти мануал можно в архивах компании, но сколько он пролежит там — неизвестно.
Возможно наш ресурс скоро станет единственным способом найти ошибку котла AEG (Аег), Junkers.
Ошибки котлов и рекомендации сервис-инженера
Советы и комментарии опытного специалиста по ремонту котлов — одна из самых ценных особенностей нашей системы.
Выберите производителя, укажите код неисправности — и получите название, описание, рекомендацию производителя и комментарий сервис-инженера.
Если комментария нет — звоните, объясним значение по телефону.
Примечание: предлагаем совместную разработку. Если вы владелец оборудования или мастер по ремонту котельной техники и знаете что-то, чего не указано в таблице — пишите! Ваша информация может помочь коллегам или другим владельцам быстрее устранить поломку.
Обратите внимание: в некоторых инструкциях ошибки котла приводятся очень лаконично: в формате «код — значение».
В нашем сервисе вы найдете подробное описание, развернутый совет. Даже если основная рекомендация — вызвать специалиста или обратиться в газовую службу.
Расшифровка ошибок — первый этап диагностики котла
Индикация неисправностей в моделях с электронной панелью управления и дисплеем помогает определить состояние котла.
Можно даже «поставить диагноз» удаленно — посмотрите значение,рекомендации мастера.
Если самостоятельно выполнить обслуживание невозможно — сообщите код при оформлении заявки.
Сервис инженер заранее подготовится к работе — захватит необходимые запчасти, инструменты, расходники.
Мы занимаемся комплексным обслуживанием — от компонентного ремонта плат котлов до разработки и обустройства котельных с нуля.
Пользуйтесь онлайн подбором ошибок котлов бесплатно
Мы потратили очень много сил, времени и денег на сбор и доведение «до ума» базы ошибок, но всю информацию о кодах неисправностей, рекомендации из инструкции и пояснения сервис-инженера предоставляем бесплатно.
Хотите помочь проекту? Поделитесь ссылкой на страницу в соцсетях, отправьте коллегам, владельцам газового оборудования.
Не рекомендуем чинить котёл самостоятельно.
Сообщите нашему специалисту код ошибки, чтобы он взял с собой нужные инструменты и запчасти.
Это поможет максимально быстро устранить неисправность.

Газовый котел Viessmann имеет множество различных функций и довольно сложное устройство. Поэтому, если вы не имеете представление о внутреннем соединении узлов, лучше вызвать мастера сервисного центра, который быстро обнаружит проблему и отремонтирует агрегат.
When your Viessmann boiler encounters an issue, the boiler will lockout and cease to function as a safety precaution. The boiler will then display an error code/fault code on the LCD display on the front of the boiler to help you identify what has caused the issue.
This error code list is to help you identify the problem with your Viessmann boiler, we don’t advise you to try and fix your boiler yourself. This error code list is a guide to help you identify the issue with your Viessmann boiler. Only a Gas Safe registered engineer should attempt to fix your boiler.
If your boiler isn’t working but it isn’t displaying a fault code either then check your water, gas, and electricity supplies to ensure there is no issue with supply. If you have a prepay meter, make sure you have credit. Check your property has running water from the cold taps, that your gas is working by lighting the hob or gas fire and that your electricity is working by turning on a light.
Your boiler may be on a separate circuit, so if the rest of your home has electricity but the LCD display on your boiler isn’t displaying anything your boiler may not be receiving power and you may need to call an electrician or Gas Safe engineer. To know more about the parts that make a combi boiler, check out our blog.
If you’re reading this blog thinking ‘it will be easier to buy a new boiler’, then why not complete our online survey, which helps you get a boiler quote in only 90-seconds. To help you choose your new boiler, we have a Boiler Comparison tool that allows you to compare up to three boiler models or brands at one time, to help you find the best new boiler for your home.

Is it time to get a new boiler?
At some point, your boiler might stop heating your home as it used to, despite its regular yearly service.
If you’ve noticed that your heating experience has changed, i.e. your radiators are taking longer to heat up, or your boiler is losing pressure regularly (more than usual), it might be time to invest in a new boiler.
But before you commit to the big purchase, ask a heating engineer to check that there isn’t a build-up in your heating system preventing your boiler from working as it should.
However, If your boiler keeps breaking down, it may be cheaper, in the long run, to cut your losses and get a new one, just come to us at WarmZilla and we’ll sort you out!
When shopping around for a new boiler, we’d advise using the WarmZilla boiler comparison tool. Just select up to 3 boilers you want to compare and you’ll be able to compare key stats side by side to see which boiler is best for your home.
