Reason: The filter element contains too many impurities, which makes it difficult to absorb oil.The filter element is the core of the machine .The accumulation of impurities will make the filter element blockage , which lead to the increase of pressure.

Solution: replace the filter element


3. The temperature controller show nothing

Reason: The oil temperature thermometer didn’t work or the heater was burnt out, the line was cut off, or the contact arm did not match.

Solution: overhaul the line, replace the heater and adjust the temperature controller.
