Pro Press 100 / Pro 100 / Pro 100 plus
Belt Noise
A Worn belt – Over time the belt may become dry or worn due to heat and
travel. – Replace the belt
Tight – If the belt was recently replaced or adjusted, the tension may be to
high (to tight). – Adjust the belt
Alignment – If the belt is rubbing against the chassis while traveling, it may
make a squeaking or rubbing sound. – Adjust the belt
Motor Noise
Over tightening – If the motor was recently replaced then the screws
holding the motor to the chassis may have been over tightened. If this is
the case then the casing may be pulling away from the housing. This will
be visible when the chassis top (keyboard) is opened. – Replace the
Dirty Motor brushes – If the motor brushes are dirty the motor will not
function properly and sometimes make an audible grinding sound. –
Remove the motor brushes and clean.
Lift will not go up in steps
Check the program parameters.
Call Whip Mix to have the lift calibrated
Lift will not go up or down
If the motor will not go up, then the motor is bad or the main board is bad
– Call Whip mix for support.
If the motor will not go down then there may be vacuum in the muffle, if
not then the motor or main board may be bad.
The first things to check are the power cord (plugged in?), the circuit breaker and
the fuses.
Melted Fuse Holder – Power loss accompanied by the smell of burning
plastic is a possible indicator that the fuse holders have melted due to
overheating, power surge, increased resistance on the power board
terminals. – This can be repaired at whip Mix or replaced.
Stuck fuse holder socket – If a fuse has gone out and cannot be removed
completely. It was probably over tightened or turned in the wrong
direction. – Unplug the unit and remove the remaining fuse segments,
replace with a new fuse and install power cord. Make sure the unit has
power, if not then check the power section of the FAQs.
Runaway Temperature
This is usually caused by a failed relay stuck in the closed position. This
can be brought on be excessive heat. If the unit is placed to close to other
devises that generate heat or is in a room with poor circulation. – Replace
the relay, check the surrounding area, and check airflow.
No Heat
The muffle wire (element) has opened (broken) or the solid-state relay has
failed in the open state. If the wire failed there are sometimes scorch
marks in the section of the muffle that the wire failed. If the relay failed the
unit will not heat even with a new muffle.
Vacuum Leak:
A vacuum leak can come from anywhere there is an opening in the vacuum
system. Vacuum valve plungers that have worn over time usually cause
them, sometimes the vacuum pump can be weak causing the same effect to
the porcelain.
1. Run a vacuum test (User Manual)
a. If the numbers on the left and middle drop after a short time then
there is a leak.
2. Clean the table
3. To find a vacuum leak
a. Remove the back cover
b. Locate a pair of hemostats or vice grips
c. Run a vacuum test and leave it in the hold mode
d. Clamp the clear vacuum hose (near the lift)
e. If the numbers stop dropping then the vacuum leak is in or near the
f. If the numbers continue to drop then the leak is at or near the
vacuum valves. If this happens then the numbers will decrease
very quickly.
4. If the vacuum leak is near the muffle:
a. The thermocouple potting may have come away from the bolt it sits
b. If the thermocouple was replaced recently then check for sufficient
Teflon tape on the thermocouple and brass plug on the top of the
muffle next to the thermocouple.
5. If the Vacuum leak is in the lower half of the furnace then the vacuum
valve plungers are usually the culprits. Replace the plungers.
Vacuum will not release:
1. Limit switch malfunction
2. Vacuum valve plunger failure
3. Vacuum sensor failure
If the vacuum will not release and work is in the muffle, unplug the unit,
remove the top cover, and unscrew the brass plug on the top of the muffle
next to the thermocouple. This will release the vacuum. Lower the table
using a large flat head screwdriver. Using the brass bolt at the back and
bottom of the unit.
Once the work has been removed, replace the brass plug (using Teflon tape)
and the top cover.
Run a vacuum test (Special Functions Menu – Test Furnace)
When the vacuum test is initiated and the table is down (all the
way) the number on the right will read “99”. If the table is between
top and bottom it will read “0”. If the table is all the way up it will
read “99” and the pump will begin to run. The table has to be up
and the display reading “99” in order for the vacuum test to begin.
If the vacuum test runs and the vacuum will still not be released
then the vacuum valve plungers probably need to be replaced,
specifically the on toward the front of the furnace. The vacuum
valve plungers are inside the furnace where the vacuum hose is
Vacuum will not rise:
Check the vacuum hose connection and vacuum pump.
Run a vacuum program, when the vacuum pump starts, listen to see if the
sound of rushing air can be heard near where the vacuum hose plugs in.
If so then one of the vacuum valves has failed.
General Malfunction
If the furnace displays a series of blocks on the top line of the display, then the
logic board has lost all memory and will need to be reprogrammed at Whip Mix.
Error Messages
1. “Start =Load code”. Furnace software has not been loaded. Generated by
the kernel.
2. “No code box”. Kernel tried to load software from the blue box but failed to
find the blue box. Check if the blue box is attached. If it is, it may be
damaged. Generated by the kernel.
3. “COMPUTER FAILURE”. Error generated by the kernel indicating that CPU
has encountered an internal error. This message is sometimes accompanied
by another message explaining the nature of the error.
4. “CPU clock fail”. CPU has detected an incorrect oscillator/clock signal.
Could mean a bad oscillator, bad CPU (HC11), unstable power line, etc.
Generated by the kernel.
5. “COP watchdog”. A bad CPU, bad oscillator, unstable power line, bad fan
switch, bad SSR, or software error could cause this error, which is generated
by the kernel.
6. “Illegal opcode”. A bad CPU, bad RAM, or error in software can cause this
error, which is generated by the kernel.
7. “Software irq”. This error is caused by an illegal interrupt request, usually
generated by a software error, but could also mean a bad CPU, bad RAM,
etc. Generated by the kernel.
8. “Unknown error”. Unknown error.

test that is run before each pressing program. Check all press and press
sensor board wiring. Check the pressure supply line.
13. “No Connection!!” This error is generated only on the versions of software
that support silver wire calibration. This error indicates that the silver wire is
disconnected even before the calibration temperature was reached. Check
how tightly silver wire is wrapped around the posts.
14. “Thermo cpl error”. This error is generated if furnace reads temperature
above 1200°C, it thermocouple is disconnected, or if open thermocouple is
The thermocouple circuit is open. This is usually an indication that the
thermocouple has failed or gone out. – Replace the thermocouple.
The unit has overheated above 1200C for more than 1 minute. – Check
solid-state relay and thermocouple. If the previous are ok, then the main
board may need to be checked
15. “No vacuum”. Furnace cannot pull vacuum. Check if vacuum pump is
connected (both the power and the air tube). Check vacuum valves.
Sometimes this error indicates bad top limit switch.
16. “Not enough vac”. Furnace cannot maintain vacuum or pull vacuum fast
enough. Check for obvious leaks. Sometimes this error indicates bad top
limit switch.
17. “Receive Error”. Furnace cannot read programs from the red box. Check if
the red box is connected. If it is, this error may indicate bad red box

operations cannot be performed with the vacuum in the chamber.
22. “Cal temp error”. Error has been encountered while trying to calibrate
temperature. Check parameters and try again.
23. “Transmit Error”. Cannot write programs to the red box. Check the
presence of the red box. On older versions of software it is possible to
receive this error even with a good red box. Try writing to it multiple times.
24. “Check Programs”. Program memory area is corrupted.
25. “Calibrate Temp”. Temperature calibration memory area is corrupted.
Recalibrate temperature.
26. “Calibrate Vacuum”.
Recalibrate vacuum.
Vacuum calibration memory area is corrupted.
27. “Calibrate Lift”.
Error was found in lift operation.
Recalibrate lift.
Sometimes this error indicates bad limit switch or corrupted memory.
28. “Check Memory”. General memory is corrupted. Check furnace settings
(idle temperature, night mode temperature, etc.)
29. “Low Voltage”
When a Low Voltage warning occurs on the display there are two possibilities,
internal malfunction or low external supply: If the low voltage warning
appears erratically then the most probable possibility is an external cause. If
the low voltage warning happens consistently than an internal malfunction is
Intermittent low voltage:
1. Has the voltage supplied from the outlet on the wall been low?
2. Is the furnace power cord on an extension cord or an outlet multiplier? The
furnace should be on it’s own outlet or dedicated outlet.
3. Is there any large devise (such as an air conditioner or other large
equipment) in the building that turns on and off in conjunction with the low
voltage warning?
If yes was answered to any of the questions above, the following may be the
solution to the problem:
1. Ensure the proper voltage on the outlet line.
2. Place the furnace on it’s own dedicated outlet.
3. Check for other devises in the building or buildings in close proximity for
large devises that may be causing the low voltage. Then suggest the use
of a power conditioner if this is the case.
