Why is my Arebos Florence (AR-HE-SPA4SLH) hot tub not heating up even after performing a reset?

If your Arebos Florence (AR-HE-SPA4SLH) has stopped heating despite performing resets, please check the following common causes and solutions based on the manufacturer's troubleshooting guide:Check the Filter Cartridge: A clogged or dirty filter is the most common cause of heating issues. If the water flow is restricted, the heater will shut off as a safety precaution. Remove the filter and try running the heater briefly without it; if the temperature begins to rise, clean or replace the filter cartridge.Water Level: Ensure the water is filled between the MIN and MAX indicators inside the tub. If the level is too low, the heating system may not activate.Heat Retention: Always use the provided insulated cover when heating. Without the cover, heat loss can exceed the heater's output, especially if the ambient temperature is low.Control Panel Status: Verify that the heater icon is active on the digital display. The system has an automatic standby function; ensure the desired temperature is set (up to 40°C) and the heater button has been pressed.Power Supply: Ensure the unit is plugged directly into a 240V AC outlet. The manual explicitly warns not to use extension cords, as they can cause voltage drops that prevent the heater from functioning correctly.If the unit still fails to heat after checking the filter and water levels, there may be an internal component failure. Since your unit was set up only a week ago, it should be under warranty. You should contact Canbolat Vertriebs GmbH (Arebos) customer support for a potential replacement unit or technical service. Note: If the control panel displays a specific error code (e.g., E1, E3), please provide that code for more specific guidance.
