Pump Motor Test Cable (7201) . If the
Pump runs normally, replace the Diode
Assembly (10409) . The Diode
Assembly is the Black Wire connected
to the Pump and brown wire next to the
yellow wire on the
8 Wire Cable
Assembly (18206 ). NOTE: Use only
the Pump Test Cable (7201) to test the
Pump . There is a Diode inline on this
cable. ALSO: Over time the test Diode
may need replacing.
Pump running at full strength, very little
or no pressure to floor or hand tool
