The washing cycle does no proceed automatically however it does so when the dial is manually advanced. What could be the problem and how to sort it?

I understand that your washer is not advancing and stuck on one cycle. If you provide a Model and serial number, it will be helpful.

Possible that the timer module is faulty and there is no switching when the cycle proceeds to the spin mode.
Please check the timer module for any loose connection or dry joints on the module.

then you've got a timer problem

Yes sorry

timer is probably faulty

The timer has a motor used to advance it through the cycles. If the machine fills with water and the timer stays in one position no matter where you put it......even in the spin cycle, then replace your timer.

whirpool machine .. it was overload and now it's not draining the water. stops when in the drain cycle./

ohm out the lid switch, with the switch closed it should read contunity if it does not then the lid switch is the issue

Yes there is a small motor just like in most wall clocks the gears strip or the gear bushing slips and refuses to advance the dial.
you have to replace the whole timer unless you know MacGyver microsurgery

Cant understand how the machine will revolve on the 'spin cycle' & yet you can hear the motor on the 'wash cycle' but yet it doesnt revolve!!
Nomally if the water fills, & the tub revolves without the programmer advancing, its because the heater is not working. ie faulty thermostat, heat element, or maybe a wire burned off in the 'heater circuit'. Check if you have 240 volts at both ends of the heat element, with a meter or 240 volt bulb
                         !! BE CAREFUL OF 240VOLTS!!
