Water supply is shut off

Soft water connection not connected to the water supply

Dirt-trap filter in solenoid valve or in the water-supply connection is dirty

Water-level sensor has limescale problem (insulating layer) or is faulty

Limescale is restricting the intake gap to the boiler

Limescale in boiler

Appliance does not have soft water supply and so there is limescale build-up in the intake

Water conductivity too low because of water softening → check water quality

Solenoid valve (-Y1) faulty

Injection nozzle in check valve clogged

Contact problems between boiler and case (ground connection)

Contact problems between water-level sensor and connector

(X21) on SIB

Not using original Convotherm cleaning agents causes foaming in the boiler and an insulating layer of limescale on the water-level probe

Пароконвектомат – незаменимая техника на профессиональных кухнях. Поломка такого аппарата является крайне нежелательным явлением для общепита, так как может привести к невозможности подачи заказанного блюда и потере клиентов. В большинстве своем ошибки пароконвектоматов зависят от некорректной эксплуатации оборудования.

Основные правила эксплуатации

• Первый запуск печи проводится с пустой камерой на протяжении получаса и при температуре +200 градусов.
• В начале рабочего дня при загрузке устройства замороженными продуктами или максимально заполнении камеры полуфабрикатами, необходимо провести предварительный нагрев камеры в течение четверти часа при температуре, которая выше стандартного режима на 40 градусов.
• При выкладке сохраняет расстояние между полуфабрикатами не менее 2-х см.
• Открывать камеру во время процесса приготовления рекомендуется как можно реже, чтобы сохранить стабильность температуры.

Важно! Своевременное сервисное обслуживание и ремонт неполадок исключат выход техники из строя и предупредят увеличение расхода электроэнергии.

Пароконвектомат Abat: ошибки

Наиболее частными погрешностями работы ПКА Чувашторгтехника являются:

• Е02 (появляется после нажатия кнопки включения и сопровождается звуковой сигнализацией) – повышение предельной температуры (от +75 градусов) в зоне контроллера либо неисправность последнего.
• Е11 (при выставлении программы «Пар») – закрыт кран, подающий воду на пароконвектомат, либо открыт кран слива воды из бойлера, либо недостаточный уровень воды в устройстве (не покрывает электрод).
• Е04 (при попытке запуска устройства) – обрыв термопары.

Подробно все возможные погрешности в работе агрегата и неисправности описаны в руководстве по эксплуатации.

Ошибки пароконвектомата Unox и Rational

Чаще всего при работе с устройством Унокс встречаются следующие поломки:

• ЕЕ1 – неисправность проводки, соединяющих датчик камеры с источником питания.
• AF01 – перегревание мотора при выполнении функции «конвекция».
• AF02 – запуск аварийной термо-защиты.
• EF4 – перегрев двигателя вентилятора.

Наиболее частые нарушения функциональности устройства Rational серии SCC:

• OPEn – отсутствует подача воды.
• E7 – неисправность термопары платы управления.
• E8 – поломка регулятора температур.
• CHnG bAtt – потребность замены батарейки в блоке управления, пр.

Не представляет сложности расшифровать коды ошибок пароконвектоматов, но не всегда удается самостоятельно исправить поломку даже при наличии соответствующей инструкции. Компания Кобор предлагает не только купить теплотехнику от лучших производителей, но также и услуги по ее обслуживанию и ремонту для жителей Москвы и области. Посмотреть товары и цены можно в каталоге нашего интернет-магазина. Обеспечивается доставка по всей России.
