The holding switch is located on
the mounting plate, near the central cam. The holding switch can
be differentiated from the water inlet switch by the thick spacer
which raises the holding switch off of the mounting plate. Also,
the holding switch uses three wires, while the inlet switch uses
only two.
Remove the switch by removing the
two screws that hold it in place. The switch is connected by three
wires. Label the wire placement on the switch before disconnecting
the wires. The wires are connected to the switch with slip-on
connectors. Firmly pull the connectors off of the switch terminals
(do not pull on the wire). You may need to use a pair of needle-nose
pliers to remove the connectors. Inspect the connectors and the
terminals for corrosion. If the connectors are corroded they should
be replaced.
