Checking fuses
Fuse arrangement (see page 76):
■ Fuse F1 is located on the cross con-
nect PCB.
■ Fuse F3 is located on the main PCB.
Fuses F1 and F3:
■ 6.3 A (slow), 250 V~
■ Max. power loss ≤ 2.5 W
Danger
Contact with 'live' components
can lead to serious injury from
electric current.
Before working on the equip-
ment, always ensure that
the
power circuit is also at zero
volt.
Removing fuses does
not switch
the power circuit to zero volt
.
Appliance too noisy
Possible causes:
■ Transport bracket not removed: See
page 67.
■ Hose outlets in diaphragm grommets
not watertight: See page 108.
■ Casing door not tightly sealed: See
page 125.
