Error Description Comments
09 Vacuum Contactor Coil Overload The contactor coil amperage was detected above 2.4 amps for more
than 5 seconds.
• Check for wiring problems on the coil circuit and repair wiring.
• Check resistance on the contactor coil. If the value is less than
50 Ω, replace the contactor.
10 Brush Contactor Coil Overload The contactor coil amperage was detected above 2.4 amps for more
than 5 seconds.
• Check for wiring problems on the coil circuit and repair wiring.
• Check resistance on the solenoid coil. If the value is less than
45 Ω, replace the contactor.
11 Chemical Pump Overload The pump coil amperage was detected above 2.4 amps for more
than 5 seconds.
• Check for wiring problems on the motor circuit and repair wiring.
• If the actual current through the pump is high, replace the pump. It
is a solenoid driven diaphragm pump and a uid blockage will not
increase amperage.
