Fault

Cause

Correction

Mixer does not work

Plug connections of
the power supply are
loose

Check the mains
plug, fasten if
necessary

Folding propeller
does not open

Blades deformed
Blades stuck

Replace the folding
propeller
Clean carefully

Mixer shaft vibrates
strongly

Folding propeller
does not open
Shaft bent
Motor shaft bearing

Clean carefully or
replace the folding
propeller
Replace the shaft,
check the folding
propeller
Send in the complete
mixer for repairs

Liquid leaks from the
leak holes in the
flange housing (mixer
connection side)

Floating ring or motor
shaft seal damaged

Send in the complete
mixer for repairs or
renew replaceable
parts

Liquid leaks from the
shaft coupling
(coupling side)

Mixer shaft seal
damaged

Send in the complete
mixer for repairs or
renew replaceable

Replace mixer shafts that are no longer perfectly centred because they cause unbalanced shaft rotation. This
in turn wears out the motor shaft bearing and damages the floating ring and motor shaft seals. Depending on
the extent of the damage, liquid is then able to penetrate into the motor, which can short circuit.
