The center tower is not able to go all the way down after a cycle

main control board is possibly bad

Hello. I need the make/model to help you accurately. However, if the washer has the tower that has center sections which rise when water is pumped, there might very well be debris clogging the main pump and preventing it from getting adequate water. A lot of those units have a spray arm assembly that can be removed by turning a round collar with a 2-3 inch "handle" sticking out--it looks like a "measuring cup". If your washer has this, remove this filter assembly and clean out any food/debris beneath and inside it. Get your user manual--it will tell you how to do this. The segmented tower depends on adequate water pressure to make it expand and spray--if you hear the main pump going and the tower is not rising, the pump is starving for water--hence the blockage theory. If you are unsure about doing any of this, call for service.--definitely provide the model number here so I can determine more accurate help for you! I hope I helped you and THANKS!

The machine control board is programmed to allow a maximum continous fill time of six minutes
or an accumulated fill time of 8 minutes for each full wash cycle.
If the required fill time exceeds the time limit, the washer will shut down.
This is to prevent flooding in the event there is a loose hose clamp or damaged air dome hose.
Check the incoming water lines for a minimum pressure of 20 psi.
If lower, the customer can use smaller clothes loads and reduce the pressure to 10 psi.
An alternative solution would be to change the plastic inlet screens to metal screened washers
and remove the nozzle extender found in the water valve inlet hose near the dispener inlet."

Push the fabric softener cup down and turn it to lock it into place

if the tower isn't rising DURING the wash cycle it is most likely caused by one of 2 issues. 1 being too low of a water level which can be caused by low flow thru the pipes, blocked filter in the inlet valve, or a bad inlet valve. The 2nd cause can be low pump pressure due to the main food shredder screen, located below the large plastic "filter" in the rear right-hand corner, being plugged with garbage. The valve can be replaced if needed, the filter can be cleaned w/o removal of the entire unit, but if the water flow is low, you will most likely need a plumber.

consult your owner manual about you are unsure about if the machine is acting anormally
Some machines, is running hot water during cycles, other cold water during cycles.

God bless you

It's an auto-clean internal lint filter. Lint is trapped from water circulating through the filter during the wash cycle. During the drain cycle it's backwashed and the lint goes down the drain.

di you try to remove the drawer completely and check for a blockage under he dispenser itself.(sometimes te fabric softener can get kinda gunky.. if you extend the dispenser you see a little black tab in top left corner, push it down and dispenser will release, just in case you didnt know that
