High-severity Warmhaus fault codes

Your boiler has detected that the water pressure in the system is too low or the pressure sensor settings are incorrect, causing the unit to stop working.

Your boiler has too much water in the system, causing it to shut down to prevent damage from excessive pressure.

Your boiler has lost the ability to measure the temperature of your tap water, meaning you will likely have no hot water until the sensor is fixed.

Your boiler has lost its connection to the sensor that monitors the heating temperature, causing the system to stop running to prevent damage.

Your boiler has shut down because the internal exhaust gases have reached a dangerously high temperature, triggered by a safety sensor.
