BUZZ NOISE ON AND OFF CHECKED HOSE DOESNT SEEM TO BE CLOGGED ALTHOUGH CANT REMOVE END FROM WASHER SIDE CANT BLOW THROUGH, DISPOSAL LINE NOT CLOGGED I USE AN AIR LOCK TUB WONT DRAIN TRIED TO RESTART JUST BUZZES
Hi, there may be an obstruction in the pump housing that is causing the motor to freeze or, the impeller may be stripped and , jamming the pump. this will cause the hum you are hearing. the best way to inspect is to , extract the drain pump by, removing
the bottom drain filter housing or sump. manually
move the pump impeller to self it is moving freely. if the impeller is stripped, it will not be able to produce the draining surge necessary to pull the water out.
If the impeller is fine and, there are no obstructions visible, this will confirm pump failure.. replace the pump in this case
Some models have two impellers inside the pump - one, wash impeller, takes care of the wash cycles, the other, drain impeller, drains the water out. If the drain impeller is broken (broken blades, shaft), the dishwasher would not drain. Replace any broken pump components.

It is a common fault that the drain fails to work in
most machines in a period of time and is the most problematic fault in a
washing machine. In all occasions it is important that your observation is most
important and so is vital to the identification /rectification and solution. If
you have noticed that water has leaked then as the drain hose pump/valve and
fittings are located on the underside of the machine it is important that you
look for possible leaks here. In some cases the drain hose would be clogged at
the drain end to outlet of the house and so there will be back flushing
resulting in overflow to the outside. Also the drain pump/valve can be clogged.
Now remove the drain hose clamps and remove the drain pump/valve, clean the
drain pump/valve, use back flushing to clear off all dirt. Now test using power
to see if this works and can be simulated. When refitting, the hose must be tightened
properly. If the pump/valve does not work even with power then it must be
replaced. If there is intermittent power
to the drain valve/pump then the program controller unit is a suspect.
Cleaning a pump:
Finally the washer must be placed with a tilt- use a
spirit level- so that all water will drain to the outlet port and thereby there
is no residual water remaining.
