afterwards, check the cable connections to the pump. If
necessary, replace the proximity switch along with the
connector
Cable connection of the proximity switch to
the pump interrupted
Check the cable connections to the pump. If necessary, replace
the proximity switch with the connector.
Printed circuit board defective
Replace the printed circuit board
Grease line blocked
Clear the blockage (See section below on locating blockages)
