Dishwasher does not drain in normal cycle. on

Have u tried unplugging it for about 2m and plug it bk in that will master reset everything like u just bought it and see how that's works out

F8 failure (slow/no draining)

In a consumer cycle, the appliance is indicating F8 E1 (slow/no draining). This is because of wrong signals from the circulation pump read by the control board and interpreted as "water present", when there is no water. During draining (and in fact, there is no water), the failure occurs.

1. Check if drain hose is not closed/clogged
2. Drain pump faulty, harness or wiring faulty, control board faulty
3. If machine is equipped with OWl, issue might be caused by damaged or dirty OWl. Clean the sensor lenses then , if issue is not solved, replace OWI (optical water indicator).

One of the reasons for motor not draining during normal cycle is the check valve is stuck. It is meant to return to normal during drain cycle but close during wash. I think the cancel is resetting it and letting water out.

Hi,
Here is a tip that I wrote that will help you with your dishwasher not drainingproblem...

Dishwasher Problems - Waterwill not drain out

heatman101

check if some dirt got in the arms of the washer as sometime this will slow the flow of water and not allow the pressure to clean the dishes well

If there is any blockage in your diposal, water will comes up to the sink, since it happened to me. As soon I installed the air gap then it fixed the problem. No air gap, water flowing is slowing down conflicting with timed draining causing this problem. Let's think of this, if you fill up water in a 1/2 galon milk container, and you try to emty it. If you pull down straightly , it will be slow compared to pull it at an agle to let air going into the opening. The air vent helps water flow better meeting the timed draining.

As you say a clogged line or valve does not make sense.

Try running it without the heated drying and see if it empties or if the cancel button will work then.

The dishes should air dry quickly if you empty it and open the door.

It could be a defective thermostat allowing it to get too hot during the heat cycle

run another cycle, it will drain.

What Brand is it?

have you removed the filter? if it gets clogged the dishwasher wont drain. other wise is sounds like a faulty drain pump
