3. Misalignment of press lid: To verify this, do the "bookmark" test. Cut thin strips of paper and
place at different sections of the seal all the way around the press. Close the lid and secure
the latches, then try to remove the paper strips. The paper will normally be held tight. If the
paper can be pulled out, this will indicate there is a gap between the seal and the lid of the
press.
4. Diaphragm has split or has been cut:
diaphragm carefully for holes, particularly around the edges
and in the corners.
bicycle tube repair kit. (Apply the patch to the bottom of the
diaphragm.) If necessary, the diaphragm can be removed
from the press for inspection. Be sure to disconnect the
press from the power source before taking the diaphragm
out.
5. Internal vacuum leakage: Put your thumb over the hole in
the rear corner of the diaphragm and observe the reading on the vacuum gauge. If the reading
is still too low, check the following:
a. Check that all vacuum hose connections are tight.
b. Check the pump filter for blockage. Ensure the pump is off, then unscrew the filter
bowl, pull the filter cartridge out and refit the bowl. If this fixes the problem, the filter
element will need cleaning. Unscrew the retaining plate at the bottom of the cartridge
and withdraw the filter element, wash in household detergent and re-assemble.
ELECTRICAL TROUBLESHOOTING
1. Press shows no readings on temperature or timer controls:
•
Check the two circuit breakers on the rear panel of the unit. The levers should both be pointing
to the right (as seen from the back). Some models have circuit breakers with a color code –
green indicates off, and red indicates the on position.
•
Check power source – verify that the power cord is firmly connected, and that the power outlet
is live. If it is not, check the circuit breaker at the building's electrical distribution panel.
•
Unplug the power cord and check the fuses on the left side of the unit.
2. Press starts up normally, then overheats and shuts off, or the temperature controller
displays an error code such as "PFA" or "LOR".
•
Check heater relay.
Normally, this can be resolved by adjustment of the hinges at
the rear of the press.
section for the procedure.
A gap at the front of the press may also indicate that the
latches need to be adjusted. The latches should snap shut with
a firm "click" but should not be difficult to close. If they are too
loose, follow the adjustment procedure in the maintenance
section. Do not over tighten the latches, as this will cause them
to wear out prematurely and will not improve the vacuum.
Small holes can be repaired with a
