FAQ

What does the indication E-1 to E-8 on the display of my external heater mean?

As already described in the operating instructions, E stands for Error and indicates an error in the operation of the JBL PROTEMP external heater. Here you can see how each message can be easily solved.

E-1: Cause: Water temperature is at least 1 °C above the set temperature. Solution: Regulates itself when water temperature drops.

E-2: Cause: No water or air bubbles in the heater. Solution: Ensure that the heater is positioned as vertically as possible and that there is sufficient water flow.

E-3: Cause: Electronics defective. Solution: Can only be fixed by a specialist.

E-8: Cause: Temperature above 93°C. No water flow, or the inside is too soiled. Solution: Clean the inside of the heater with a hose brush (see chapter 8 Maintenance) and ensure sufficient water flow.

PUSH messages from JBL

What are PUSH messages? As part of the W3C standard, web notifications define an API for end-user notifications that are sent to the user's desktop and/or mobile devices via the browser. Notifications appear on the end devices as they are familiar to the end user from apps installed on the device (e.g. emails). Notifications appear on the end user’s device, just like an app (e.g. for emails) installed on the device.

These notifications enable a website operator to contact its users whenever they have a browser open - it doesn’t matter whether the user is currently visiting the website or not.

To be able to send web push notifications, all you need is a website with a web push code installed. This allows brands without apps to take advantage of many of the benefits of push notifications (personalised real-time communications at just the right moment).

Web notifications are part of the W3C standard and define an API for end user notifications. A notification makes it possible to inform the user about an event, such as a new blog post, outside the context of a website.

JBL GmbH & Co. KG provides this service free of charge, and it is easy to activate or deactivate.
