Fault Indication

A defect within the heating system of the flow heater (i.e.
descaling necessary) is indicated if the indicator lamp (6) starts
to burn.
Descaling is now urgently necessary - and should be per-

protective fuse will be activated within very short time and it
will be necessary to call a service technician to put the machine
back into working order.
Maintenance
Depending on water hardness and how often the machine is
used, the passage heater must be dsescaled regularly. (Hard
water + frequent use = descaling more often)
