How to fix slow water heating in Truma Combi comfort plus?
Water heating slowly in your Truma Furnace may be caused by lime scale (hard water calcification) in the water container. Decalcify the water container.
Why is water dripping from the Truma Furnace pressure relief/drain valve?
Water may drip or flow from the drainage socket of the pressure relief/drain valve for several reasons. It could be due to excessive water pressure in the system, which can be resolved by checking and adjusting the pump pressure or replacing the water pump. If a Truma pressure relief/drain valve is installed, it might be releasing pressure above 65.25 psi (4.5 bar), which is a protective function and not a fault; if this continues, contact Truma service. Other potential causes include excessive water pressure requiring replacement of the water pressure reducer by a qualified technician, or lime/dirt under the valve seat, which can be addressed by rinsing the valve.
What to do if the Truma Furnace water container cannot be emptied?
If the water container cannot be emptied even when the pressure relief/drain valve is open, it is likely that the drainage socket is obstructed. Clear any obstructions such as slush, ice, or leaves from the opening of the drainage socket. Ensure that the faucets are opened to the 'hot' position.
