Troubleshooting
Fault Cause Remedy
‡ Motor does not start > Fuse of the mains socket
has blown.
• Connect mains fuse.
> Overload protection switch
has tripped.
• Switch off the vacuum
cleaner and allow it to cool
for approx. 5 minutes. If the
cleaner cannot be started
again, contact the Mirka
Service department.
> Motor is faulty. • Have motor changed by
Mirka Service.
‡ Motor does not run
in automatic mode
> Power tool/pneumatic tool is
defective or not connected
properly.
• Check that the power tool
works or that the plug is
inserted correctly.
> The power rating of the
electrical tool is too low.
• Note that minimum power
rating is P>40W
‡ Reduced suction
power
> Suction power selected with
suction power control is too
low.
• Set suction power in ac-
cordance with section „Set-
ting suction power“.
> Hose diameter does not
correspond with switch
position.
• Set correct switch position
for hose diameter.
> Clogged suction hose/noz-
zle.
• Clean suction hose/nozzle
> Tank or Fleece bag is full. • See „Emptying tank“ or
„Replacing Fleece bag“
sections.
> Filter element is clogged. • See section „Cleaning filter
element“ and „Replacing
filter element“.
> Seal between tank and
upper section of vacuum
cleaner is faulty or missing.
• Replace seal.
> Cleaning mechanism is
defective.
• Contact Mirka Service.
‡ No suction power
during wet cleaning
> Tank is full. • Switch off the cleaner.
Empty the tank.
‡ Voltage fluctuations > Impedance of power supply
is too high.
• Connect the cleaner to
another socket closer to the
fuse box. Voltage fluctua-
tions over 7% should not
occur if the impedance
at the transfer point is
≤ 0.15 Ω .
