4.7. Tank Components
The tank internals are detailed below. Care should be taken when cleaning inside the tank.
The level probes provide much of the control inputs into the PCB and are critical to the operation of
the machine. The wiring to these should be checked regularly and the probes themselves should be
cleaned whenever the machine is serviced.
There are 3 level probes on the 10L Ecoboiler versions and 2 level probes on the 5L versions.
The Ecoboiler T10 tank is shown below – only the low level probe is visible in the picutre.
