7.1 CAT135
1. The filter may be clogged. If the filter is damaged, replace it.
2. A foreign object may have be lodged in the flexible pipe. Unscrew the flexible pipe from the elbow and
check it by shining a light through it, or using a probe, such as a piece of wire, to inspect it.
3. The pump may not be receiving power. Check the power cord to be sure it is plugged in. Check the
breaker switch for the power supply to be sure it has not kicked out. If so, check for the error condition that
caused it to break before resetting it.
4. The pump may be jammed or burned out. Listen for the sound of the pump. You should be able to
determine if it is attempting to turn or if it is silent. If silent, it must be replaced. If attempting to turn ask a
