TROUBLE SHOOTING

LACTEK II
Caution do not open side panels without first turning power OFF to the machine.

(The faster way to test motors and wiring is to use a Multi tester (They are available at hardwarestore, Walmart, etc.)                                    how to use a multi meter (youtube video)








1- Water Valve
2-PC Board
3-Powder motor
4-Heating element
5-water pump
6-Mixing Motor
7-Thermostat
8-Water tank
9-Float valve

-----------------------------------------------------------------
Feeder does not start
No water, no powder, no mixing .
*****Check if power going to feeder
Unplug feeder.
Plug an other devices into outlet ( electric drill, etc)
If it does not work there is not power at the plug.

*****Switch on /off  in off position.
Turn switch on.

*****Mixing bowl full

Drain mixing bowl.

*****Faulty sensor probe.

 
 *- Clean mixing bowl and sensor probe.
  *- End of Sensor probe should be  1/4 inch from head of sensor bolt
and should show at least 1/2 inch of bare wire.

  *-  Open left side panel disconnect sensor probe.
---If feeder starts, the sensor probe needs to be replaced.
---If feeder does not start, replace Lactek II PC board.
 





*******Check fuse
.





     Open right side panel locate fuse.

WATER ISSUES
No water 
in the mixing bowl but powder and mixing motor working.
 Water tank not full.
Water tank full but no water in the mixing bowl.
-----------------------------------------------
No water  in the mixing bowl but powder and mixing motor working.
*****No water going to feeder.
Faucet shut off, no water supply, etc.

***** Concentration knob turn clockwise all the way.
Turn Concentration knob counter clockwise to open concentration valve.

Unplug feeder.
Open left side panel.
Check if water tank full.
------------------------------------------------
 Water tank not full.
(the water level should be 1 inch to the top of water tank)

*****Check water valve filter.

   


   Filter is located inside water valve.






*****Check water valve.

Unplug feeder.
Open right side  panel
.

 



Disconnect  wire from water valve.
Use a multi tester set it up on resistance.
The resistance between the the 2 connector should be  1 kilo ohm.

If the value is different, replace water valve.






*****Check Float switch.

Unplug feeder.



     
Remove float from water tank.
     Clean float. check if float moves freely on shaft.






Disconnect float wire. Use a multi tester set on resistance.

 
  When the float is down the contact should be close ( no resistance).
Move float up the switch and it should open ( high resistance).
If it is different result, replace float.









--------------------------------------------
 Water tank full but no water in the mixing bowl.

 *****Concentration knob turn clockwise all the way.
Turn Concentration knob counter clockwise to open concentration valve.

*****Check for trash in the tubing or in the pump.


Remove the 3 metal clip to open pump and check if propeller is turning freely.

*****Check water pump.
Disconnect wire  and ground wire  from water pump Use a multi tester set on resistance



The resistance between the 2 connector should be 6 ohm.
It should be an open connection between ground and wire connector.
If any of these values are different,  replace water pump.

--------------------------------------------------
POWDER ISSUE
No powder but water and mixing motor are working.
Auger is turning but bring just a little  bit of powder to the mixing bowl.
----------------------------------------------------------------
No powder but water and mixing motor are working.
*****Powder switch on rinse.

*****Check if the auger is disengage.
 

Push auger all the way to the end of the tubing so it hooks back into the connector.
when the hopper is full of milk replacer , the milk replacer pushes the auger against the powder motor and keep the auger in place.
If there is object in the milk replacer (paper, cup) it is possible the that auger will become unhooked.
Object can also prevent the wiper drive to turn freely and prevent the powder motor from turning.
 


****check is powder motor is running

Turn feeder on.


If not running :

Disconnect wires  and ground wire  from powder. Use a multi tester set on resistance.
The resistance between the 2 black wires should be 9 ohm.
It should be an open connection between ground and wire connector.
If any of these values are different replace powder motor.





If powder motor is running but the milk replacer is not coming to the mixing bowl.

****Check if auger coupling is tight on powder motor shaft.

Auger is turning but bring just a little  bit of powder to the mixing bowl.



The wiper wire inside the hopper must be adjusted or bent so it  follows the  contour of the inside of the hopper.
It will prevent the formation of a hole inside the hopper.

--------------------------------------
MIXING MOTOR ISSUES
No mixing motor but water and powder are working.

****Check is shaft is turning freely
  Check if  propeller is not touching side of mixing bowl when running.
Grease mixing motor bearing if needed.




*****Check mixing motor


Disconnect wires  and ground wire  from mixing motor. Use a multi tester set on resistance .
The resistance between the 2 black wires should be 12 ohm.
It should be an open connection between ground and wire connector.
If any of these values are different replace mixing  motor.

------------------------------------------------------
MIXING BOWL ISSUES

Mixing bowl overflowing all the motor are running.


Faulty sensor probe.


   *- Clean mixing bowl and sensor probe.
*- end of Sensor probe should be  1/4 inch from head of sensor return
and should show at least 1/2 inch of bare wire.
*-  open right side panel disconnect sensor probe.
Connect together two black coming from pc board:
If feeder start the sensor probe needs to be replaced.
If feeder does not start replace Lactek PC board.

 
****Check for broken wires or loose connection

-------------------------------------------------

WATER TEMPERATURE ISSUES.



Set thermostat at 100 f.
Red light is on when power is going to heating element.
 

Red light on but cold water
****Check heating element .
Unplug feeder.
Open right side panel.










Disconnect wire  from heating element. Use a multi tester set on resistance .
The resistance between screws  should be 10 ohm.
It should be an open connection between ground and screw.
If any of these values are different, replace heating element.









Heating element removal.






Check thermostat
Unplug feeder.
open left side panel.




Disconnect wires  from thermostat. 

Use a multi tester set on resistance .

Put thermostat bulb in cold water.
Connect tester lead as on picture.
Turn thermostat knob all the way  to off position
Switch should be open (High resistance).
Turn thermostat knob so switch closes ( low resistance).
Warm up thermostat bulb switch should open when temperature is reach.

If different result replace thermostat

-------------------------------------------
LEAKS ISSUES
Water overflowing under  or inside the feeder
.

open right side panel.
Unplug feeder.
if water still running through feeder replace water valve.
There is trash inside the water valve preventing it from closing.

Check Float switch

Remove float from water tank.
Clean float. check if the float move freely on shaft.
Disconnect float wire. With a multi meter set on resistance.

 
  When the  float is down the contact should be close ( no resistance).
Move the float up the switch should open ( high resistance).
If different result replace float.
