Continuously fills with water

I'm guessing it has a float switch that shuts the water off when its full, and if it were bad it would not stop filling. Until the float switch tells the valve to close its also is not going to tell the pump to come on.

Is it possible the drain pump is running because the machine won't stop filling? Does the drain pump start running when machine start filling or doe it come on when machine is about full?

Fyi. All new washing maching already tested on their functionality and features but not test run with water intake and drain function. I would like to share My experience last time with this model. The water outlet valve will release by motor when you set to drain mode.it suppose manage to retract back by spring when drain process finish or afte small you change to wash mode.
Take a look on the spring movement.normally it not properly hold valve switch hence the retracted spring not block the valve to stop water drain. Just rectify the alignment of the valve swich which directly connected to the retractable spring.

lift the drain outlet hose higher to stop the water syphoning out as it is filling.

I would check the inverter on top of the motor. The flashin led light is a code the code legend is on the wiring schematics behind the control panel

where is water draining into? have u got grey water hose attached to it?make sure u can see end of drain hose, put into bucket at lid level, if it still drains as it fills u have a faulty control module.please reply for more help

The cleaner goes into the small bottom at the very rear of the machine. It is uses full strenght (don't add any water to it). You add clean water into the bottom clear plastic section on the front of the machine. The clean water bladder is soft plastic and it is filled from the top. When you start using the machine, the dirty water will get suctioned into the section surrounding this bladder. The machine will stop working when either the bladder is empty or the dirty water section is full. Remove the entire plastic section to dump out the dirty water.

You most likely have a stubborn clog in your kitchen drain. Try filling the sinks with warm soapy water and then letting the water drain while also turning on your garbage disposal. Sometimes the extra water pressure will help push the clog through.

you have the drain pipe too low into tthe house drain pipe, raise the washers drain pipe up , you only need four inches down into the hous drain

also the house drain pipe needs to be as high as the lid of the machine before you put the washer drain tube into the house drain

you have a syphoning effect
