If the machine fills with water and cycle starts but it does not spin and drain, then possible problems are drain hose, drain filter, pressure switch and less frequently pump.
Before advancing to spin the timer board performs a test on drain part
of the cycle, stops the drain and checks the door lock. Drain system,
pressure switch and lid switch are all parts that if defective may cause
The first part to be tested is the drain system. This
must be checked regardless of the fact that the pump is working. If
there is blockage, residual water in the drain system or water flowing
back from drain hose may cause the washer not detecting that drain is
complete, and not advancing to spin.
Disconnect power and check the drain system, accessing drain filter and hose connected to the drain pump.
most front loaders this is accessed removing the trim at the base of
the front side of the appliance (under the door), and rotating the
filter cap counterclockwise. The filter should be located behind the
trim at the base of the washer.
Top loader usually offer access to
pump either from back or from the bottom of the appliance. In some case
(eg.Kenmore top load) you have to lean the machine forware to gain
access to the bottom part of the unit, where the pump is located.
opening the pump hose cover be prepared to collect a good amount of
water. Keep a container at hand. Ensure that power is not connected
Also double check drain hose at the back of the
appliance, and check that the elbow height is as prescribed in manual.
Incorrect drain hose settings may result in syphoning, that means water
is flowing back from drain hose into the washer tube. This may result
in no spin.
After performing the check on the drain system test
washer again. Sometimes removing eventual blockage in drain pump may fix
this kind of problem.
If the pump is draining, but drain doesn't
complete, and if there is no blockage in drain lines, a parts that may
be causing the no-spin problem are pressure switch and door latch
The door latch switch is checked by electronic control
before advancing to spin. The door switch is tested running a cycle with
the door switch contacts jumped. If the model has a lock motor more
testing is needed. In that case the switch is tested ensuring that the
lock motor impedance reads according to specifications and energizing
the lock motor.
If the drain stops always at same point and cycle
does not advance replace also the pressure switch. The pressure switch
detects water level and determines when drain is over and when to
advance to spin. This part is difficult to test in full, the part is not
expensive and it is usually replaced without testing. Pressure switch
is a common failure causing no spin. If drain is OK, then either
pressure switch or lid switch/lock system is usually responsible.If the above is OK , with
top loaders you need to add to the list the problems related to motor and
transmission. In front loaders, check problems related to motor and motor control unit. Such problems will be near to the end of the troubleshooting
list. Check them before deciding to replace the electronic control.
Always disconnect power cord or trip the circuit breaker before performing maintainance operations.
