The drain hose and recirculation
hoses can be responsible for leaks. The drain hose can cause the
dishwasher to fail to drain properly. The recirculation hose can
be responsible for problems with poor rinsing of dishes.
Caution:
Please read our safety
information before attempting any testing or repairs.
Before checking the drain hose, unplug the dishwasher
or shut off the power at the fuse
box or breaker
panel to avoid an electrical shock hazard.
To access the drain hose remove
the lower panel located beneath the door. The panel is usually
held in place with two screws either above or below the panel.
It may be necessary to first open the door to the dishwasher to
reach the screws over the panel, then close the door to remove
the panel.
The drain hose connects to the pump
and runs to the sink drain (or to the air gap on top of the sink).
The pump has a second hose that recirculates the water back into
the dishwasher. The drain hose is roughly 1 1/2 inches in diameter.
While inspecting the drain hose, check the recirculation hose
as well.
If checking for leaks, feel the
hoses where they connect to the pump, for wetness and check the
ground right under the connections. If they are wet, it may be
a loose or improperly mounted clamp, a damaged pump housing or
a leak in the hose itself.
If checking for blockages, disconnect
the drain hose from the pump, pinch the wire clamp with pliers
and slide it up the hose. Place a shallow pan beneath the pump
to catch any spillage. Remove the hose from the pump; wiggling
the hose may help to loosen it.
Check the hose and nipple to the
pump for any debris. The only way to be certain the drain hose
is completely clear is to disconnect it from the sink and run
water through (such as spraying a garden hose through it at full
pressure). Disconnect the recirculation hose and check it in the
same way.
Reconnect the hoses and replace
the clamps. Replace the lower panel and restore electricity to
the dishwasher.
