Water is spewing out of the air vent on the back my washer

    I have the same problem with my washer. Water and suds actually shoot out of the air vent on the back of my washer as it spins, not while it’s filling. What is the purpose of this air vent and can I fix it. Thank you.

I really need more information here. Are you saying that there is water spewing out as soon as the fill starts, or does the machine fill and fill and fill until it finally comes out of the vent.

If the latter is the case, then this is almost certainly a faulty pressure switch. It may need replacing or it may have just come loose in the machine and be hanging in a position that causes it not to work (I only saw this happen once, but in my own machine as it happens!). To investigate, you will need to take the top off the machine (My article will explain this). and then take a look at the switch.

You are looking for a circular device, a little smaller than the palm of your hand with 2 electrical wires and a plastic tube about the thickness of a pencil attached to it.
The way this thing works is that as the water in the machine fills up, it pushes a little water up the tube and the pressure of the water compresses air in the tube which operates a tiny bellows device in the unit, switching a microswitch in it and cutting power to the taps that let the water in.

You MAY be able to fix it without replacing it. with the machine empty and unplugged from the mains, remove the tube and blow down it to clear any water in the tube out (If more water that there should be got into the tube, the air pressure as it fills will be too low and the cutoff won't work, blowing down the tube clears out the water and the switch may now work properly again when the tube is replaced.

If this fails, then you will need to replace the switch. Anyone who deals in washing machine parts will be able to source one for you. The goos news is they are fairly cheap.

Water spewing from steam vent whenever I cook rice and I have measured accurately. It is a mess!

I found a solution to the spewing around the lid and through the vent.

The other day I placed the steamer tray in the top and then the lid.

The steamer "broke up" the bubbles -- no spewing out of the pot or mess -- I mostly happened with brown rice -- but the last 2 times -- not mess!!!!! Hope this helps someone else.

Kemore Elite Dishwasher Spews Water When Wash Cycle Begins

After further inspection of my dishwasher I found a bad gasket under the lower wash arm. Over the years it finally gave up and was shooting a torrent of water through the water in the bottom of the wash tub. When all that water hit the door liner it went up into the lower door vents, into to wire harness, and onto the floor.

LG WM2487 front load washer spews suds out of port on rear.

You are likely using too much detergent or the detergent is not high-efficiency detergent. Change detergents and/or lower amount and this problem should go away.

The water port on the back allows air inside the tub to escape. However, if the wrong type or quantity of detergent are used, excess suds will flow from this port.

LG WM-2077 Water leaks out of the Air Vent on the back

Be sure you are using HE detergent and only about 1 Tablespoon for a load. You are ending up with too many bubbles in the machine and when it goes to spin the bubbles come out the air vent. There is a valve that closes during spin but bubbles are not strong enough to lift the valve it has to be water hitting it before it closes.
