    What to do if Maquet Heater shows “TEMP >= 40°C” alarm?
    • S
      scottrobertsonAug 18, 2025
      If the Maquet Heater displays the message “TEMP >= 40°C” and you can't acknowledge it with the “Alarm Off” key, it could be due to several reasons. First, the water tank might be empty, so refill it with water. Second, there might be insufficient heat dissipation; avoid operating the unit continuously for more than one hour without the tubes and oxygenator. Third, the ambient temperature could be too high; allow the unit to cool and observe the maximum ambient temperature. Finally, there could be a sensor short circuit T2, in which case you should contact customer service.

    What to do if Maquet HU 35 Heater displays “WATER LEVEL!?” alarm?

      If the Maquet Heater displays the message “WATER LEVEL!?” and it can be acknowledged with the “Alarm Off” key for 10 minutes, it indicates that the water level is too low, so you should refill it with water. Another reason might be that the unit is not positioned horizontally, so ensure that the unit is placed horizontally. It may also indicate a sensor error.

    How to fix no water circulation in Maquet HU 35 Heater?
    • A
      Anthony HughesAug 22, 2025
      If you're experiencing no or insufficient water circulation in your Maquet Heater, there are several potential causes: * The tubes might be kinked. Ensure that the tubes are laid and positioned correctly. * The couplings may not be clicked into place. Push the couplings together firmly. * The unit could be positioned well below the oxygenator. Position the unit at the same height or higher. * The pump may be worn out or defective.

    Why does my Maquet Heater display “HEAT EMISS. 0 W”?
    • M
      Mary BurgessSep 5, 2025
      If you see the display message “HEAT EMISS. 0 W” or “WARMING-UP TIME” on your Maquet Heater, the heat dissipation value is not being shown because the setpoint and actual temperature are not the same. Heat dissipation is only shown if the setpoint and actual temperature are the same.

    Why is the coupling valve dripping on my Maquet HU 35?
    • A

      If the coupling valve of the coupling which is not connected drips continuously on your Maquet Heater, it could be due to a damaged or soiled inner sealing ring. Try connecting and disconnecting the coupling several times.
