My washer is leaking what can be the problem

If you open the top you will see a circular disc with a thin rubber tube attached to it. This is an air pressure switch that switched off the water supply when it reaches its level. When the machine is unplugged remove the tube from the switch and blow into it. It should be clear. Next blow into the little fitting on the switch , if the tube is ok ,and it should click. Either the switch is faulty or the tube is blocked,detached from the machine or burst. Hope this helps.

I did as Drunan did and unplug for 10 and plugged it back in and it started like a champ! Thanks!!!!!! ;)

F35 is a water level error.
The water level switch (pressure switch) has malfunctioned.

If you remove the top panel, three screws in the back, you will have access to the pressure switch.

With the tub empty, remove the vinyl hose from the switch and blow backwards through the hose to clear any restrictions.

If the fault codes return after doing this, you will likely need to replace the pressure switch.


Also - please be sure to use He soap.
