Troubleshooting
There is no power.
• Plug the machine into proper outlets.
• Check the circuit breaker. Other devices should not run on the same circuit as the
extractor. Use a 20 amp outlet.
Pump does not work properly.
• Make sure solution line quick disconnects are properly connected.
• Check Solution tank. May be empty.

• The system could be vapor locked, which results from activating the heater before
the pump. Release pent-up pressure by removing extractor outlet disconnect, or by
depressing the disconnect inner poppet valve using a dull plastic object (such as a
pen). Resume operation, using proper technique outlined beginning on page 6.
• Check outlet disconnect. Remove to test. Replace if necessary.
• Hanging heater check valve. Remove hose to heater check valve, and manually
manipulate the internal valve poppet ball with straightened paper clip. Replace hose
to test. Replace faulty check valve (B108).
Unit is tripping circuit breaker(s).
• Ensure that only a 20 amp circuit is being used.
• Use only a cord approved for the machine.
• Do not add any extension cords to those cords supplied for use with extractor.
• Faulty component may be drawing excessive amperage. Check each component
separately.
• Faulty circuit breaker at site. Use another outlet.
