6.- Troubleshooting
In case that we have a breakdown at the machine Z22, we must proceed to look over the machine
following next guidelines.
1.
The motor doesn’t run:
a.
Check if the machine is connected to the mains.
b.
Check over the grating disc and try to move it. (check if it’s not blocked)
c.
Check if there’s continuity between both push button (On and Off)
d.
Check if there’s continuity between the locking arm switch
e.
Check the capacitor’s capacity
f.
Check the motor winding resistance
a)
When the motor doesn’t start working, first of all, we will check if the motor has the right
voltage. We will use the voltmeter to test if we have the right voltage at the plug (220V. or
110V.)
b)
If the plug has voltage and it’s still not working, we must try to move the grating disc carefully
to check if it can be move easily
with the hand. It’s for ensure that the motor is not blocked.
Proceed always with the machine disconnected from the mains.
c)
If the grating disc moves softly and it’s not blocked, we will proceed to dismantle the plastic
base cover for leaving visible the buttons.
(see point 2.1)
Once we have both buttons visible, we must check the continuity on the closed contact (OFF)
and on the open contact (ON). We will use a voltmeter for check continuity between both green
circles (open contact) and ensure that when we push the button we have continuity and when
it releases we lose continuity; it means that the contact is ok. For check the closed contact we
will check continuity between both yellow circles (closed contact) and we must have continuity
without pushing it, and when pushing the button, we lose continuity. If this happens it means
that both buttons are ok.
