Overflowing through door

WATER PRESSURE SWITCH: This switch keeps your washer from overflowing. It is responsible for shutting off the power to the fill valve and redirects the power to the timer to start the washing machine running once the correct water level has been reached. Meter check ur water pressure switch?
You can test it with a meter and with a manual test? ( first locate it in the panel, it has a plastic clear tube hose going into it, remove that tube from its connection, now put another small tube or hose into the slot where it was and have the machine set to wash cycle with water in it. Blow into the other end of the tube.
If the machine starts to wash. the pressure switch is more than likely good
( No wash starts - then THE DIAPHRAGM IS BAD AND SWITCH HAS TO BE REPLACED) another test u can do is Remove the hose and submerge in water. Seal one end and blow air into the other end and look for bubbles. Check for an obstruction in the hose

also may want to check the door switch

If the washer keeps filling up without overflowing onto the floor , then you have the drain hose too deep into the drain and it is siphoning, pull the drain hose back up from being so deep and have it only about 10 inches into the drain, tie it into place with a shoestring or wire tie.
Now if your problem is that the washer is overflowing onto the floor, then there is a clear rubber hose that has been disconnected from the washer, this is the diaphragm hose. Have a technician reattach it. It shuts the water off and starts the machine when its gets enough water, but it wont if the hose is disconnected. Mr Burk

Consider that the problem may not be the float as mentioned. Leaking can be as simple as the door seals, or misalignment. If someone slams the door or runs into the door from the side, the normal alignment can be out of adjustment. Check the locking tab under the counter and see it that was moved and reset it. Seems you already fussed with the system and it did not solve the problem.

The water float switch, located on the inside bottom of the machine, may be stuck in the up(off) position keeping the water valve from functioning. This is a safety device that turns the water valve off when the machine fills in order to keep it from overflowing.

The water inlet solenoid mounted on the inlet valve under the bottom front may also be malfunctioning not allowing the water valve to open and fill the machine. If electricity is present at the solenoid terminals when the machine is in fill cycle, then check the solenoid coil to see if it is open(no continuity). Also, the timer may not be calling for water/ sending voltage to the inlet valve solenoid.

I would start by manually operating the water float valve a few time to see if that helps. You should hear a microswitch click each time the valve stem is moved up or down by the float. If not, check to see if voltage is getting to the float switch and the water inlet valve solenoid.

Most(if not all) machines have a safety cutoff switch which activates when the door is opened. That switch could also be malfunctioning not allowing voltage to the water inlet valve solenoid in fill cycle.

The water input on washers is controlled by the timer which actuates the solenoid valves for both hot and cold water, telling them when to fill and when to close. I would run the machine thru a fill cycle with the washer back off, and with a voltmeter, observe if the voltage ever cuts off as the timer runs. I Another variable is the water level control. So also determine if that is working since if it failed to open the 'fill' circuit at the proper volume, you might have this overflow problem.

sometimes if the door switch of that machine is not working so there is no auto stop of filling water. or the pressure switch may be not function well.

Your pressure switch stops the water and allows it to start the next cycle. It's a switch either in the control panel or at the top of the tub with a small tube connected to it which goes down between the inner and outer tub. As the water level increases the air in the tube is compressed until there is enough pressure to make the switch stopping the water from filling. This tube can get clogged and the switch won't work. Remove the tube and clean it out. Blowing on the tube when it's still connected to the switch will make the switch if it's working and clear.

Water inlet valve

If it fills with water and starts the cycle and the water keeps running in then your water inlet valve on the back where the water supply comes in is sticking. It needs replacing.

Top load or front? If top loader, the pressure fill switch may be unplugged or broken. Hose leads from the switch to the tub. If the hose is disconnected or has a hole in it, or is plugged the washer will continue to fill with no shutoff.

try unblocking the inlet hose under the machine.. My machine was overflowing inlet water into the tray under the machine setting off the above mentioned aquastopper switch. I removed side pannel, then one end of the inlet hose under the machine and dragged a wire with cloth tied to end through, removing a serious amount of built up scum. no more overflowing!!

fill valve may be hanging open and can be very intermitant may be switch but ck valve first start water entering machine shut washer off and notice if valve takes extra time to shut off if it does would suspect valve problem
