Check and Action Check the wiring to the Low Level probe and the Probe inside the tank. - Page 14 This is a non recoverable error. The machine needs to be reset when this problem is solved. Probable causes: 1. The elements have failed 2. Wiring fault Action required: 1. Check that the resistance on the elements. If there is a reasonable resistance (15-25Ω)on the element it probably has not failed, so the wiring might be at fault.

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. -
Page 16: Descaling Procedure
4.8. Descaling Procedure To descale the machine thouroughly: Unplug the machine. Disconnect from the water supply. Drain as much water from the tank as possible. Remove the lids and allow the machine to cool completely. Drain all the water from the machine. Attempt to remove as much scale as possible by hand. - Page 17 4.9.
