I have an LK 550 AquaMix on which I have replaced the insert. I now have insufficient heat: is there anything I can do about this?
You can increase the maximum temperature. You can do this as follows:
- Turn the knob counterclockwise to (+).
- Loosen the screw and put the knob to one side.
- Then turn the knob in the "air" clockwise towards (–). This adjustment can be made incrementally, with a ¼ turn corresponding to approx. 7°C.
- Replace the knob and feel for when it grips the cog.
- Fasten the screw and then turn the knob to max (+). Maximum calibration to increase the temperature is a ½ turn

Why is my safety valve leaking?
Is it OK to have water coming out of the wastepipe? When water is heated, it expands and the increased volume needs to go somewhere, meaning that your safety valve will drip.
