or unplug cord at wall receptacle.

2. Remove the cabinet top.

3. Remove the float switch wire from the L1 wire nut, and check for

continuity across this wire and terminal 3 of the solid state relay.
With the float in the raised position, the circuit should be open.
With the float in the lowered position, the circuit should be closed.
If the float is not defective, reconnect the float switch wire to the
L1 wire nut.  If it proves defective, continue with the steps below.

                                                 Step 5

switch.

                                                 Step 6

9. Strip the end of the cut wire from step 4, and attach it to one of

the new float switch wires, using a wire nut.

10. Connect the other float switch wire to the L1 wire nut.
