It is a common occurrence for limescale to build up in the tank of a water boiler. The
amount of limescale build up is relative to the water hardness in a particular area.

Water level below low level probe. Machine has to be
refilled manually (shown only in MANUAL mode).
Status LED – 2 red blinks.
Water is being heated. Dispense valve disabled.
Water is up to the temperature and can be used. Note that
this only means that the tank is heated and not that it is
full.
Status LED – green.
Water is being dispensed. If machine is set to time
dispenses – there will also be a progress bar drawn
underneath. Dispense can always be cancelled by clicking
the dispense button again.
Machine was set by the user to a lower temperature than
the current tank temperature and is trying to cool down by
taking in more cold water. This process may take between
20 seconds to a few minutes depending on tank size and
temperature difference. Works only in COOL FILL mode.
Machine cannot take more cold water to cool the tank
because it is full. Water needs to be dispensed to allow
room for more cold water to come in and finish cooling
process.
Descale timer elapsed. Time to descale the tank.
Litres output exceeds set value.
Time to change the water filter.
Low water level probe broken (disconnected). Machine
detects high level probe signal but cannot detect low level
one. Filling is disabled. Status LED – 1 red flash.
Temperature sensor (thermistor) is short circuited.
Dispense and heater disabled. Status LED – 3 red
flashes.
Heating element is broken. Error is triggered when after
20 minutes of heating and not taking in water temperature
in the tank fails to increase.
Dispense is disabled. Status LED – 4 flashes.
Temperature sensor (thermistor) is disconnected.
Dispense and heater disabled. Status LED – 5 red
flashes.
Incoming water pressure too low. The error will be reset
after water supply restores.
All boiler functions are active. Status LED – 6 flashes.
Display board lost communication with boiler PCB (cannot
receive serial data about temperature and probes).
All actions cancelled.
